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:Arsenic (As) is a carcinogenic metalloid that is a contaminant widely polluting rice paddy soils around the world. In order to gain better insight into molecular mechanism of rice exposed to As(III) stress, we used next-generation sequencing technology to acquire global transcriptome alteration and miRNA regulation in rice upon As(III) treatments. Our results suggest time course and As(III)-dosing treatments were devised. Cluster analyses show that root and shoot samples were differentially grouped. For roots, sub-clusters were more distinct in the dosage course whereas for shoots they were most recognizable for the time course treatments. Other than the significantly regulated gene expression in the heavy metal-responsive sulfur and glutathione metabolism pathways, the expression of genes related to heavy metal transportation, jasmonate biosynthesis and signaling pathways, lipid metabolism and gene transcription were sharply regulated, indicating that rice allocates energy and resources from growth to stress response under As(III) stress. In addition to the detection of previously identified stress-related miRNAs, we further discovered 36 new As(III)-responsive miRNAs. These results expand our understanding of As(III) stress mechanism to the As(III)-responsive mRNA and miRNA transcriptomes, which provide a foundation for subsequent functional research.

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:To understand the dynamics and global gene reprogramming in the early response to mechanical wounding in rice, the transcriptional response to mechanical injury was analyzed. A time-course experiment revealed the highly dynamic nature of the wound response in rice. Mechanical wounding triggered extensive gene expression reprogramming in the locally wounded leaf, affecting various physiological processes, including defense mechanisms and potentially tissue repair and regeneration. The rice response to mechanical wounding displayed both differences and similarities compared to the response to jasmonate treatment. These results highlight the importance of early JA signaling in response to mechanical stress in rice. This analysis provides an overview of the global transcriptional response to mechanical stress in rice, offering valuable insights for future studies on rice's response to injury, insect attack, and abiotic stresses.

Project description:In our earlier study, thiourea has been shown to improve the growth of rice and reduce the arsenic load from aerial parts of the seedlings. We have also shown the applicability of thiourea to delineate the redox regulatory mechansisms under arsenic stress in rice. To move further, present microarray was performed to reveal the involvement of overall gene and regulatory netwrok under arsenic with/without thiourea treatment in rice.
