Current State of Research and Teaching Activities
We use forward and reverse genetic approaches to elucidate the logics of plant development, with a special emphasis on "COMPENSATION", a phenomena whereby cell size compensate for cell division in establishment of leaf size. In particular, we focus on the fugu series of mutants (fugu1~fugu5) and others in our laboratory.
We have established close collaborations with scientists in other research groups both within and outside Japan.
We have launched this homepage to share with you our excitement about new discoveries, research activities and interests, and to keep you informed about the opportunities to join our laboratory or to collaborate with us.

- Elucidation of the strategies of mechanical optimization in plants toward the establishment of the bases for sustainable structure system, Grant-in-Aid for Scientific Research on Innovative Areas (Research in a proposed research area), 29 Jun. 2018 - 31 Mar. 2023, Competitive research funding, これまで、植物が機械刺激を内生発生プログラムに反映し利用している可能性については、ほとんど議論されてこなかった。多くの植物発生研究者が、研究手法の確立した分子生物学的・遺伝学的研究を行っている状況の中で、植物を対象とした張力測定や張力の人為的なコントロールといった機械刺激を扱う実験手法が確立されてこなかったことがその要因である。本研究では、植物がもつ2種類の構造システム形成戦略、(1)表皮のタガとしての機能と内部構造の最適化戦略システム、および、(2)重力を含む機械刺激による根系形成の最適化戦略システム、を読み解くことで、機械刺激が植物の形態形成を制御し、力学的構造最適化を図るしくみを明らかにする。このデータをもとに、様々な機械的攪乱に強い建築基礎のモデルを提案することを目的としている。
- ピロリン酸の過剰蓄積が植物の発生に及ぼす影響の時空間的解析, Grant-in-Aid for Scientific Research (B), 01 Apr. 2016 - 31 Mar. 2019, Competitive research funding, Pyrophosphate (PPi) is generated by biological reactions, and its removal is essential for proper cell functions. In plants, H+-PPase is responsible for the removal of PPi, and the H+-PPase loss-of-function mutant fugu5 over-accumulates PPi, and displays postgerminative developmental and growth defects. In this study, the various developmental abnormalities caused by excess PPi have been analyzed in a developmental stage, tissue, and cell type specific manner, in order to elucidate the role of H+-PPase in plant metabolism and developmental regulation. As a result, we demonstrated that the effect of excess PPi differs among leaf tissues, that the degradation of PPi within guard cells is essential for exerting normal stomatal function, and that temporary removal of PPi during the initial phase following seed germination is proved to be necessary and sufficient to recover all developmental abnormalities in fugu5 background.

- 植物初期生育における液胞プロトンピロホスファターゼの役割の解明, Grant-in-Aid for Young Scientists (B), 01 Apr. 2012 - 31 Mar. 2014, Competitive research funding, Following germination, oil-seed plants rely on triacylglycerol (TAG) reserves for growth during a heterotrophic period, where TAG is converted to sucrose (Suc). Also, macromolecular syntheses consume huge amounts of ATP, often hydrolyzed to AMP plus PPi. In Arabidopsis, the vacuolar H+-PPase uses energy from PPi hydrolysis to acidify the vacuole. The fugu5 mutants, lacking the AVP1 H+-PPase, failed to sustain postgerminative heterotrophic growth; recovered upon Suc supply, or specific PPi removal by the cytosolic PPase IPP1. Thus the major function of H+-PPase in seedling development is the removal of inhibitory PPi, rather than H+ pumping. Suc and PPi quantification in WT versus fugu5 indicated that gluconeogenesis is inhibited by elevated level of PPi, but the targets of PPi inhibition remained unclear. Here, profiling of major metabolites that occur during TAG mobilization showed that UDP-Glucose Pyrophosphorylase (UGPase) is specifically inhibited by excess cytosolic PPi in fugu5.
- Molecular anaysis of CUC2 functional specificity, Grant-in-Aid for Scientific Research (B), 01 Apr. 2011 - 31 Mar. 2014, Competitive research funding, Morphogenesis of organisms is regulated by various types of proteins. Among such regulatory proteins, transcription factors constitute a major class of proteins that turn on and off gene expression. CUC2 is a transcription factor required for normal development of various plant organs including leaves and fruits. We investigated the function of CUC2 in detail using the model plant Arabidopsis thaliana (thale cress), and found mechanisms that confer different functions in development of the two organ types.
- Role of vacuolar-type proton pump in compensated cell enlargement, Grant-in-Aid for Young Scientists (B), 01 Apr. 2009 - 31 Mar. 2010, Competitive research funding, A longstanding question in biology is how organ size is predetermined. Compensation is a key, yet unsolved phenomenon, whereby decreased cell number below some threshold triggers enhanced post-mitotic cell expansion in leaf primordia. Thus providing a model case to investigate leaf-size control. Among the Arabidopsis mutants that exhibit compensation, here I focused on fugu5 mutant that is defective in vacuolar-type H^+-pyrophosphatase (H^+-PPase). I clearly demonstrated that high accumulation of PPi in the cytosol mediates gluconeogenesis compromise in fugu5, providing evidence that PPi hydrolysis is the major role of FUGU5 in vivo. Also, I conducted a large-scale screening of enhancers, repressors and suppressors of fugu5 mutant and identified three mutant lines that affect cell expansion in fugu5 in different manners. Finally, I found that V-ATPase is implicated in excessive cell enlargement observed in fugu2-1 and KRP2 o/e.
- Plant regulatory systems that control developmental interactions between meristems and lateral organs, Grant-in-Aid for Scientific Research on Priority Areas, 01 Apr. 2007 - 31 Mar. 2012, Competitive research funding, A number of new findings on mechanisms of differentiation, cell expansion, and morphogenesis in leaf primordia have been obtained from analyses of Arabidopsis thaliana and new model systems such as genera Juncus and Asparagus. These were totally new and some are breakthrough in understanding of molecular mechanisms of leaf organogenesis. The original reports on these findings have been published on top journals, and four of them were chosen by F1000.
- Molecular basis of regulation of organ size-Molecular genetic approaches to reveal mechanisms of compensation, Grant-in-Aid for Creative Scientific Research, 01 Apr. 2006 - 31 Mar. 2010, Competitive research funding, Our studies on mechanisms of leaf development have revealed that an unknown system integrates activities of cell proliferation and cell expansion in leaves, depending on non-cell autonomous regulations. We also showed that gene expression not only regulates leaf form, but the resulting organ shape also secondarily regulates gene expression in a particular part of the organ primordium. These findings strongly indicate importance of understanding of the organ-level integration of cell behaviors to reveal mechanisms of organogenesis in multicellular organs.

- Contributions of lignification, tissue arrangement patterns, and cross-sectional area to whole-stem mechanical properties in Arabidopsis thaliana
26 Apr. 2024, Mariko Asaoka, Eric Badel, Ali Ferjani, Kazuhiko Nishitani & Olivier Hamant, joint, Journal of Plant Research, Springer Nature, 10.1007/s10265-024-01543-2, Plant cells withstand mechanical stress originating from turgor pressure by robustly maintaining the mechanical properties of the cell wall. This applies at the organ scale as well; many plant stems act as pressurized cylinders, where the epidermis is under tension and inner tissues are under compression. The clavata3 de-etiolated3 (clv3-8 det3-1) double mutant of Arabidopsis thaliana displays cracks in its stems because of a conflict between the mechanical properties of the weak epidermis and over-proliferation of inner stem tissues. In this work, we conducted three-point bending tests on various Arabidopsis thaliana mutants, including those displaying the stem cracking phenotype, to examine the differences in their mechanical properties. The clv3-8 det3-1 double mutant exhibited reduced stem stiffness, consistent with reduced differentiation due to the clv3-8 mutation. Yet, in clv3-8, stem cross-sectional area was increased associating with the increase in vascular bundle number, and stem cross-sections displayed various shapes. To uncouple the contribution of geometry and cell-wall differentiation to the mechanical properties of the whole stems, we tested the contribution of lignified fibers to stem stiffness. In order to suppress lignin deposition in stems genetically, we generated multiple higher-order mutants by crossing clv3-8 and/or det3-1 with nst1-1 nst3-1, in which lignin deposition is suppressed. Stem stiffness was reduced markedly in all nst1-1 nst3-1 mutant backgrounds. Overall, our results suggest that stem stiffness relies on the presence of differentiated, lignified, fiber tissue as well as on the alignment or spatial distribution of vascular bundles within the stem organ. - The phosphorylated pathway of serine biosynthesis affects sperm, embryo, and sporophyte development, and metabolism in Marchantia polymorpha

04 Aug. 2022, Shizuka Gunji, Kensuke Kawade, Hiromitsu Tabeta, Gorou Horiguchi, Akira Oikawa, Mariko Asaoka, Masami Y Hirai, Hirokazu Tsukaya, Ali Ferjani, joint, Frontiers in Plant Science, Frontiers, 13, 945225, Research paper (scientific journal), 10.3389/fpls.2022.945225, Excess PPi triggers developmental defects in a cell-autonomous manner. The level of inorganic pyrophosphate (PPi) must be tightly regulated in all kingdoms for the proper execution of cellular functions. In plants, the vacuolar proton pyrophosphatase (H+-PPase) has a pivotal role in PPi homeostasis. We previously demonstrated that the excess cytosolic PPi in the H+-PPase loss-of-function fugu5 mutant inhibits gluconeogenesis from seed storage lipids, arrests cell division in cotyledonary palisade tissue, and triggers a compensated cell enlargement (CCE). Moreover, PPi alters pavement cell (PC) shape, stomatal patterning, and functioning, supporting specific yet broad inhibitory effects of PPi on leaf morphogenesis. Whereas these developmental defects were totally rescued by the expression of the yeast soluble pyrophosphatase IPP1, sucrose supply alone canceled CCE in the palisade tissue but not the epidermal developmental defects. Hence, we postulated that the latter are likely triggered by excess PPi rather than a sucrose deficit. To formally test this hypothesis, we adopted a spatiotemporal approach by constructing and analyzing fugu5-1 PDF1pro::IPP1, fugu5-1 CLV1pro::IPP1, and fugu5-1 ICLpro::IPP1, whereby PPi was removed specifically from the epidermis, palisade tissue cells, or during the 4 days following seed imbibition, respectively. It is important to note that whereas PC defects in fugu5-1 PDF1pro::IPP1 were completely recovered, those in fugu5-1 CLV1pro::IPP1 were not. In addition, phenotypic analyses of fugu5-1 ICLpro::IPP1 lines demonstrated that the immediate removal of PPi after seed imbibition markedly improved overall plant growth, abolished CCE, but only partially restored the epidermal developmental defects. Next, the impact of spatial and temporal removal of PPi was investigated by capillary electrophoresis time-of-flight mass spectrometry (CE-TOF MS). Our analysis revealed that the metabolic profiles are differentially affected among all the above transgenic lines, and consistent with an axial role of central metabolism of gluconeogenesis in CCE. Taken together, this study provides a conceptual framework to unveil metabolic fluctuations within leaf tissues with high spatio–temporal resolution. Finally, our findings suggest that excess PPi exerts its inhibitory effect in planta in the early stages of seedling establishment in a tissue- and cell-autonomous manner. - Looking beyond the gene network: metabolic and mechanical cell drivers of leaf morphogenesis
19 Apr. 2022, Hokuto Nakayama, Hiroyuki Koga, Yuchen Long, Olivier Hamant, Ali Ferjani, joint, Journal of Cell Science, The Company of Biologists, 135, 8, Research paper (scientific journal), 10.1242/jcs.259611, The above-ground organs in plants display a rich diversity, yet they grow to characteristic sizes and shapes. Organ morphogenesis progresses through a sequence of key events, which are robustly executed spatiotemporally as an emerging property of intrinsic molecular networks while adapting to various environmental cues. This Review focuses on the multiscale control of leaf morphogenesis. Beyond the list of known genetic determinants underlying leaf growth and shape, we focus instead on the emerging novel mechanisms of metabolic and biomechanical regulations that coordinate plant cell growth non-cell-autonomously. This reveals how metabolism and mechanics are not solely passive outcomes of genetic regulation but play instructive roles in leaf morphogenesis. Such an integrative view also extends to fluctuating environmental cues and evolutionary adaptation. This synthesis calls for a more balanced view on morphogenesis, where shapes are considered from the standpoints of geometry, genetics, energy and mechanics, and as emerging properties of the cellular expression of these different properties. - A Practical Example of Flower Organ Development and Genetics in High-School through the ABC Model Arabidopsis Mutant Inquiry-Based Observation Activity
Dec. 2021, GUNJI Shizuka, YASUNAGA Mariko, FERJANI Ali, joint, Bull. Tokyo Gakugei Univ. Div. Nat. Sci., Tokyo Gakugei University, 73, Research paper (bulletin of university, research institution), 2434-9380, To teach about the common nature and diversity of life phenomena, biology courses cover a wide range of subjects from the molecular to the macro levels. Scientific activities such as experiments and observations are indispensable to explore them. In this report, we focused on the ABC model of flower development and the mutants of Arabidopsis thaliana (Arabidopsis), a model plant, as a teaching tool for studying genetics, regulation of gene expression, and organ development. Since the effect of a single mutation on the gene involved in the development of floral organs is easy to realize, we thought that it would be easy to make students understand the basic concepts of genetics, gene expression, and development. This time, a special lecture was held for students in the first and second years of high school, and observations of mutants related to the ABC model were conducted. As a result, the students were able to experience the process of building the ABC model from mutant observations and perceive the invisible reality of “genes” in the form of phenotypes of floral organs. Based on these results, we will discuss the prospects for using the Arabidopsis ABC-model mutants as a teaching tool. - An auxin signaling network translates low-sugar-state input into compensated cell enlargement in the fugu5 cotyledon.
06 Aug. 2021, Hiromitsu Tabeta, Shunsuke Watanabe, Keita Fukuda, Shizuka Gunji, Mariko Asaoka, Masami Y Hirai, Mitsunori Seo, Hirokazu Tsukaya, Ali Ferjani, joint, PLOS GENETICS, PLOS, 17, 8, Research paper (scientific journal), 10.1371/journal.pgen.1009674, How leaf size is determined is a longstanding question in biology. In the simplest scenario, leaf size would be a function of cell number and size. Yet, accumulating evidence on the model plant Arabidopsis thaliana suggested the presence of compensatory mechanisms, so that when the leaf contains fewer cells, the size of each cell is unusually increased (the so-called compensated cell enlargement (CCE)). While decreased cell numbers in the compensation exhibiting fugu5 mutants have been ascribed to reduced sugar biosynthesis from seed oil reserves, molecular mechanisms underlying CCE remain ill-known. Recently, IBA (a precursor of the phytohormone auxin) has emerged as a potential regulator of CCE. Here, to further illuminate the role of IBA in CCE, we used a series of high-order mutants and analyzed their genetic interaction with fugu5. We found that while CCE in fugu5 was promoted by IBA, defects in IBA-to-auxin conversion, auxin response, or the vacuolar V-ATPase activity alone cancelled CCE. This provides a scenario in which following seed germination, the low-sugar-state triggers auxin synthesis, leading to CCE through the activation of the V-ATPase, illustrating how fine-tuning cell and organ size regulation depend on interplays between metabolism and auxin levels in plants. - Multiple functions of the vacuole in plant growth and fruit quality

Lim, Ari Pekka Mahönen, Richard J. Morris, Bela M. Mulder, Naomi Nakayama, Ross Sozzani, Lucia C. Strader, Kirsten ten Tusscher, Minako Ueda and Sebastian Wolf, joint, Quantitative Plant Biology, CAMBRIDGE UNIVERSITY PRESS, 2, Research paper (scientific journal), 10.1017/qpb.2021.8, Quantitative plant biology is an interdisciplinary field that builds on a long history of biomathematics and biophysics. Today, thanks to high spatiotemporal resolution tools and computational modelling, it sets a new standard in plant science. Acquired data, whether molecular, geometric or mechanical, are quantified, statistically assessed and integrated at multiple scales and across fields. They feed testable predictions that, in turn, guide further experimental tests. Quantitative features such as variability, noise, robustness, delays or feedback loops are included to account for the inner dynamics of plants and their interactions with the environment. Here, we present the main features of this ongoing revolution, through new questions around signalling networks, tissue topology, shape plasticity, biomechanics, bioenergetics, ecology and engineering. In the end, quantitative plant biology allows us to question and better understand our interactions with plants. In turn, this field opens the door to transdisciplinary projects with the society, notably through citizen science. - Stem integrity in Arabidopsis thaliana requires a load-bearing epidermis.
