Biological function of antisense RNAs that are synthesized by RNA-dependent RNA polymerases under abiotic stress

Project description:To identify RDR1/2/6-dependent antisense RNA loci under 2hr drought stress, expression profiles of Poly (A+) RNA and Poly (A-) RNA between rdr1/2/6 and wild-type using the custom microarray (GPL19830) were analyzed. rdr1/2/6 and wild-type plants (Arabidopsis thaliana ecotype Columbia) were grown on MS medium for 2 hours. Then, the plants were transferred to plastic dish and kept for 1 week. Poly (A+) RNA and Poly (A-) fractions were separated from 100Î¼g total RNA by treating with Ambion Poly A purist twice. Poly (A-) RNA sample was prepared by depleting rRNA using Invitrogen RiboMinus Plant Kit. 5 ng of Poly (A+) RNA and 1.4 Î¼g of Poly (A-) RNA samples were used for the expression profiling using the custom array (GPL19830).

Comprehensive analysis of rice transcriptome during dehydration and rehydration

Project description:Drought is a harmful abiotic stress that threatens the growth, development, and yield of rice plants. To cope with drought stress, plants have evolved diverse and sophisticated stress-tolerance pathways by regulating gene expression. Previous genome-wide studies have revealed many rice drought stress-responsive genes that are involved in various metabolism, hormone biosynthesis and signaling pathways, and transcriptional regulation. However, little is known about the regulation of drought-responsive genes during rehydration after dehydration. In this study, we examined the dynamic gene expression patterns in rice seedling shoots during dehydration and rehydration using RNA-seq analysis. To investigate the transcriptome-wide rice gene expression patterns during dehydration and rehydration, RNA-seq libraries were sequenced and analyzed to identify differentially expressed genes (DEGs). DEGs were classified into five clusters based on their gene expression patterns. The clusters included drought-responsive DEGs that were either rapidly or slowly recovered to control levels by rehydration treatment. Representative DEGs were selected and validated using qRT-PCR. In addition, we performed a detailed analysis of DEGs involved in nitrogen metabolism, phytohormone signaling, and transcriptional regulation. In this study, we revealed that drought-responsive genes were dynamically regulated during rehydration. Moreover, our data showed the potential role of nitrogen metabolism and jasmonic acid signaling during the drought stress response. The transcriptome data in this study could be a useful resource for understanding drought stress responses in rice, and may provide a valuable gene list for developing drought-resistant crop plants.
