Project description:Chilling stress is a major abiotic stress that affects rice growth and development. Rice seedlings are quite sensitive to chilling stress and this harms global rice production. Comprehensive studies of the molecular mechanisms for response to low temperature are of fundamental importance to chilling tolerance improvement. The number of identified cold regulated genes (CORs) in rice is still very small. Circadian clock is an endogenous timer that enables plants to cope with forever changing surroundings including light–dark cycles imposed by the rotation of the planet. Previous studies have demonstrated that the circadian clock regulates stress tolerances in plants show circadian clock regulation of plant stress tolerances. However, little is known about coordination of the circadian clock in rice chilling tolerance. In this study, we investigated rice responses to chilling stress under conditions with natural light-dark cycles. We demonstrated that chilling stress occurring at nighttime significantly decreased chlorophyll content and photosynthesis efficiency in comparison with that occurring at daytime. Transcriptome analysis characterized novel CORs in indica rice, and suggested that circadian clock obviously interferes with cold effects on key genes in chlorophyll (Chl) biosynthesis pathway and photosynthesis-antenna proteins. Expression profiling revealed that chilling stress during different Zeitberger times (ZTs) at nighttime repressed the expression of those genes involved Chl biosynthesis and photosynthesis, whereas stress during ZTs at daytime increases their expression dramatically. Moreover, marker genes OsDREBs for chilling tolerance were regulated differentially by the chilling stress occurring at different ZTs. The phase and amplitude of oscillation curves of core clock component genes such as OsLHY and OsPRR1 are regulated by chilling stress, suggesting the role of chilling stress as an input signal to the rice circadian clock. Our work revealed impacts of circadian clock on chilling responses in rice, and proved that the effects on the fitness costs are varying with the time in a day when the chilling stress occurs.

Project description:It is important to reveal the regulatory mechanism of OsMYB30 gene which participated in cold response. We used microarrays to find differentially expressed genes that might be regulated by OsMYB30 and resolve its regulation mechanism. The rice gene OsMYB30 was overexpressed in the two OsMYB30 overexpression plants (OE2 and OE28) compared to the control plant (CK, ZH11). The rice gene OsMYB30 was knocked out in the two osmyb30 homozygous mutants (mutant1 and mutant2) compared to the wild type (WT, Huayang).OE2-C0h and OE28-C0h are two repititions of OsMYB30 overexpression plants under normal conditions with CK-C0h used as control plant. OE2-C6h and OE28-C6h are two repititions of OsMYB30 overexpression plants under cold stress conditions with CK-C6h used as control plant. mutant1-C0h and mutant2-C0h are two repititions of osmyb30 homozygous mutant plants under normal conditions with WT-C0h used as control plant. mutant1-C6h and mutant2-C6h are two repititions of osmyb30 homozygous mutant plants under cold stress conditions with WT-C6h used as control plant.

Project description:Basic region/leucine zipper (bZIP) transcription factors play vital roles in the abiotic stress response of plants. However, little is known about the function of bZIP genes in Camellia sinensis. Here, we show that CsbZIP6 is induced during cold acclimation in tea plant. Constitutive overexpression of CsbZIP6 in Arabidopsis lowered the plants’ tolerance to freezing stress and ABA exposure during seedling growth. Compared to wildtype (WT) plants, CsbZIP6 overexpression (OE) lines exhibited increased levels of electrolyte leakage (EL) and malondialdehyde (MDA) contents and reduced levels of total soluble sugars (TSS) under cold stress conditions. Microarray analysis of transgenic Arabidopsis revealed that many differentially expressed genes (DEGs) between OE lines and WT plants could be mapped to ‘response to cold’ and ‘response to water deprivation’ terms based on GO analysis. Interestingly, CsbZIP6 overexpression repressed most of the cold- and drought-responsive genes as well as the starch metabolism under cold stress conditions. Taken together, our data suggests that CsbZIP6 functions as a negative regulator of the cold stress response in Arabidopsis thaliana, potentially by down-regulating cold-responsive genes. To obtain insights into the molecular mechanisms by which CsbZIP6 mediates senstivity to cold stress in Arabidopsis plants, gene expression profiles in leaves of two CsbZIP6 OE lines and WT plants under normal (22ºC) and cold (4ºC) conditions were compared. The Agilent Arabidopsis Gene Expression (4×44K, Design ID: 021169) was used in this experiment.

Project description:The experiment tested organ-specific responses of rice (Oryza sativa ssp. japonica) to cold stress with a special focus on phytohormonal regulation. Cold stress (5°C, 24 h) was applies on the whole plants, leaves or roots. The results showed distinct responses when cold stress was applied on leaves, relating to photosynthesis and sugar synthesis as well as specific changes in phytohormones. On the other hand, stress applied to roots was more similar to the stress on the whole plant indicating roots to be more important in cold stress responses. Acclimation by mild temperature (15°C, 12 h) highlighted changes which are connected even with lower temperature exposure or which are characteristic for untreated organs. Recovery (3 d) indicated ability of plants to restore growth which correlated between individual phytohormones and plant growth. The article connect transcriptome, hormonome, proteome and sugar analyses of rice cold-stress responses.
