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:Using the HiSeqTM 2000 sequencing platform, the anther transcriptome of photo thermo sensitive genic male sterile lines (PTGMS) rice Y58S and P64S (Peiâai 64S) were analyzed at the fertility sensitive stage under cold stress.These datas would be most beneficial for further studies investigating the molecular mechanisms of rice responses to cold stress.

Project description:The rice gene SUB1A-1 confers flooding tolerance restricting shoot growth during submergence. Rice with SUB1A also show more rapid recovery after submergence ends, but mechanisms by which SUB1A improves recovery from submergence had not been examined. In this study, the transcriptome was sequenced at five time points over a 24 hour submergence recovery period in near-isogenic rice genotypes with and without SUB1A.

Project description:IDS1 is a rice AP2-type transcription factor with transcritpional repression activity. To understand how IDS1 regulate rice salt tolerance, the ChIP-seq experiments were performed to identify IDS1 binding site in globle genomic level. The two-weeks-old rice seedlings were lysated and sonificated and IDS1-DNA complexes were immune precipated with myc-antibody and protein A beads. The purified DNA samples were used to construct sequencing libraries and sequenced with Illumina. The data were then analyzed with bio-informatic tools.

Project description:Long non-coding RNAs (lncRNAs) are essential regulators of a broad range of biological processes in plants. Spectacular progress in next-generation sequencing technologies has enabled genome-wide identification of lncRNAs in multiple plant species. In this study, genome-wide lncRNA sequencing technology was used to identify cold-responsive lncRNAs at the booting stage in rice by comparison of a tolerant variety, Kongyu131 (KY131), and a sensitive variety, Dongnong422 (DN422). GO and KEGG enrichment analysis were performed, focusing on the cis- and trans- target genes of differential lncRNAs. To identify cold-responsive genes, a meta-analysis was used to integrate cold-tolerant QTLs at the booting stage. In total, 13 cold-responsive target genes were obtained by KEGG enrichment analysis combined with meta-analysis, as confirmed by qRT-PCR. Finally, three of these genes were identified in response to cold stress. These results sought to provide new insight into cold-resistance research for rice.
