    is aiming at bridging the basic research to applied research in field. GNOM, which we recently identified as a central regulator of cold temperature stress response, is widely conserved among plant species. In the current project, we would like to identify the proteins that are trafficked by GNOM during cold stress and also investigate the roles of GNOM in tomato in relation to cold stress. Through this research, we expect to generate new tomato lines which will be able to withstand cold stress.

    Keywords : cesium, cadmium, ABC transporter

    Style of Research： Individual

    Research Program： Basic Science Research on Life Science  

    Contents of Research Career

    This project was aimed at identifying the molecular and cellular pathways that may function in detoxifying these metals. One of the major pathways for plant to detoxify toxic metals is through transporting them to vacuole and sequestering them. The ABC transporters, also called multidrug resistance proteins, are ubiquitous in plant and animal kingdom and play an important role in transporting various substances, including metals. Based on the function of ABC proteins in animal, we hypothesized that these proteins may function in transporting Cs and Cd to vacuole for detoxification. To prove or refute this hypothesis, we took a multi facet approach that includes; 1) mutant screening; 2) transcript profiling; 3) comparison of Cd content in wild-type and mutant, 4) cellular expression analysis of target proteins.

  • Actin isovariant ACT2-mediated cellular auxin homeostasis regulates lateral root organogenesis in Arabidopsis thaliana

    Hanzawa A, Rahman AA, Rahman A

    Cytoskeleton ( Willey )  0   1-13   2024.11  [Refereed]

    Academic Journal  Multiple authorship

    Lateral root (LR) organogenesis is regulated by cellular flux of auxin within pericycle cells, which depends on the membrane distribution and polar localization of auxin carrier proteins. The correct distribution of auxin carrier proteins relies on the intracellular trafficking of these proteins aided by filamentous actin as a track. However, the precise role of actin in lateral root development is still elusive. Here, using vegetative class actin isovariant mutants, we revealed that loss of actin isovariant ACT8 led to increased lateral root formation. The distribution of auxin within pericycle cells was altered in act8 mutant, primarily due to the altered distribution of AUX1 and PIN7. Interestingly, incorporation of act2 mutant in act8 background (act2act8) effectively nullified the LR phenotype observed in act8 mutant, indicating that ACT2 plays an important role in LR development. To explore further, we investigated the possibility that the act8 mutant's LR phenotype and cellular auxin distribution resulted from ACT2 overexpression. Consistent with the idea, enhanced lateral root formation, altered AUX1, PIN7 expression, and auxin distribution in pericycle cells were observed in ACT2 overexpression lines. Collectively, these results suggest that actin isovariant ACT2 but not ACT8 plays a pivotal role in regulating source-to-sink auxin distribution during lateral root organogenesis.

    To better understand the salt tolerance of the wild rice, Oryza coarctata, root tissue-specific untargeted comparative metabolomic profiling was performed against the salt sensitive Oryza sativa. Under control, O. coarctata exhibited abundant levels of most metabolites, while salt caused their downregulation in contrast to metabolitesin O. sativa. Under control conditions, itaconate, vanillic acid, threonic acid, eicosanoids, and a group of xanthin compounds were comparatively abundant in O. coarctata. Similarly, eight amino acids showed constitutive abundance in O. coarctata. In contrast, under control, glycerolipid abundances were lower in O. coarctata and saltstress further reduced their abundance. Most phospholipids also showed a distribution similar to the glycerolipids. Fatty acyls were however significantly induced in O.coarctata but organic acids were prominently induced in O. sativa. Changes in metabolite levels suggest that there was upregulation of the arachidonic acid metabolism in O. coarctata. In addition, the phenylpropanoid biosynthesis as well as cutin, suberin,and wax biosynthesis were also more enriched in O. coarctata, likely contributing to its anatomical traits responsible for salt tolerance. The comparative variation in the number of metabolites like gelsemine, allantoin, benzyl alcohol, specific phospholipids,and glycerolipids may play a role in maintaining the superior growth of O. coarctata insalt. Collectively, our results offer a comprehensive analysis of the metabolite profile in the roots of salt-tolerant O. coarctata and salt-sensitive O. sativa, which confirm potential targets for metabolic engineering to improve salt tolerance and resilience in commercial rice genotypes.

  • Heat stress impairs floral meristem termination and fruit development by affecting the BR-SlCRCa cascade in tomato

    Floral meristem termination is a key step leading to carpel initiation and fruit development. The frequent occurrence of heat stress due to global warming often disrupts floral determinacy, resulting in defective fruit formation. However, the detailed mechanism behind this phenomenon is largely unknown. Here, we identify CRABS CLAW a (SlCRCa) as a key regulator of floral meristem termination in tomato. SlCRCa functions as an indispensable floral meristem terminator by suppressing SlWUS activity through the TOMATO AGAMOUS 1 (TAG1)–KNUCKLES (SlKNU)–INHIBITOR OF MERISTEM ACTIVITY (SlIMA) network. A direct binding assay revealed that SlCRCa specifically binds to the promoter and second intron of WUSCHEL (SlWUS). We also demonstrate that SlCRCa expression depends on brassinosteroid homeostasis in the floral meristem, which is repressed by heat stress via the circadian factor EARLY FLOWERING 3 (SlELF3). These results provide new insights into floral meristem termination and the heat stress response in flowers and fruits of tomato and suggest that SlCRCa provides a platform for multiple protein interactions that may epigenetically abrogate stem cell activity at the transition from floral meristem to carpel initiation.

    Cell fate determination and primordium initiation on the placental surface are two key events forovule formation in seed plants, which directly affect ovule density and seed yield. Despite ovulesform in the marginal meristematic tissues of the carpels, angiosperm carpels evolved after theovules. It is not clear how the development of the ovules and carpels is coordinated inangiosperms. In this study, we identify the S. lycopersicum CRABS CLAW (CRC) homologueSlCRCa as an essential determinant of ovule fate. We find that SlCRCa is not only expressed in theplacental surface and ovule primordia but also functions as a D-class gene to block carpel fateand promote ovule fate in the placental surface. Loss of function of SlCRCa causes homeotictransformation of the ovules to carpels. In addition, we find low levels of the S. lycopersicumAINTEGUMENTA (ANT) homologue (SlANT2) favour the ovule initiation, whereas high levels ofSlANT2 promote placental carpelization. SlCRCa forms heterodimer with tomato INNER NOOUTER (INO) and AGAMOUS (AG) orthologues, SlINO and TOMATO AGAMOUS1 (TAG1), to repress SlANT2 expression during the ovule initiation. Our study confirms that angiosperm basal ovule cells indeed retain certain carpel properties and provides mechanistic insights into the ovuleinitiation.t SlCRCa expression depends on brassinosteroid homeostasis in the floral meristem, which is repressed by heat stress via the circadian factor EARLY FLOWERING 3 (SlELF3). These results provide new insights into floral meristem termination and the heat stress response in flowers and fruits of tomato and suggest that SlCRCa provides a platform for multiple protein interactions that may epigenetically abrogate stem cell activity at the transition from floral meristem to carpel initiation.

  • Cold stress induces malformed tomato fruits by breaking the feedback loops of stem cell regulation in floral meristem

    Fruit malformation is a major constrain in fruit production worldwide resulting in substantial economic losses. The farmers for decades noticed that the chilling temperature before blooming often caused malformed fruits. However, the molecular mechanism underlying this phenomenon is unclear.
    Here we examined the fruit development in response to cold stress in tomato, and demonstrated that short-term cold stress increased the callose accumulation in both shoot apical and floral meristems, resulting in the symplastic isolation and altered intercellular movement of WUS.
    In contrast to the rapidly restored SlWUS transcription during the recovery from cold stress, the callose removal was delayed due to obstructed plasmodesmata. The delayed reinstatement of cell-to-cell transport of SlWUS prevented the activation of SlCLV3 and TAG1, causing the interrupted feedback inhibition of SlWUS expression, leading to the expanded stem cell population and malformed fruits. We further showed that the callose dynamics in response to short-term cold stress presumably exploits the mechanism of bud dormancy during the seasonal growth, involving two antagonistic hormones, abscisic acid and gibberellin.
    Our results provide a novel insight into the cold stress regulated malformation of fruit.
