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.

Decoding drought tolerance mechanisms in Holm oak (Quercus ilex) throught a combined transcriptomics and proteomics analysis

Project description:Drought is considered as a threat to the sustainability of Mediterranean forests and, of the agro-silvo-pastoral “dehesa” system. Holm oak (Quercus ilex L.) is one of the most representative species of these ecosystems and this abiotic stress causes a high tree mortality rate, being more accused at the seedling stage. In this study, an integrative analysis of transcriptome and proteome in leaves of Q. ilex seedlings under drought conditions was carried out to identify gene products involved in the metabolic pathways related to drought tolerant mechanisms.

Full-length transcriptome of Glycyrrhiza uralensis Fisch. in under five treatment

Project description:Purpose: The goal of this study are to reveal the internal mechanism of Bacillus pumilus G5 and silicon increased Glycyrrhiza uralensis Fisch. seedlings drought-tolerance by RNA-Seq. Methods: mRNA profiles of Glycyrrhiza uralensis Fisch. Seedling in five treatment: control treatment, drought stress treatment, drought stress with G5 treatment, drought stress with Si treatment and drought stress with G5 combined Si treatment. Results: The full-length transcriptome sequencing of 15 samples was completed, and the clean data of each sample was 6.28GB. All the consistent transcript sequences were aligned to the reference genome by minimap2 software and then de-redundant analysis was performed. Finally, 37267 genes were obtained. A total of 6934 DEGs were identified in four comparisons (D vs CK, DB vs D, DSi vs D, and DBSi vs D), among which are 967, 1559, 1278 and 3130 DEGs in four comparisons, respectively. Conclusions: Our study help to better understand the underlying molecular mechanisms of Bacillus pumilus G5 and silicon improve the drought-tolerance of G. uralensis.

Title（Project name）Proteomic Investigation of the Molecular Mechanisms in Response to the PEG-Induced Drought Stress in Soybean Roots

Project description:Roots are generally the critical drought sensors, but little is known about their molecular response to drought stress. We used the drought-tolerant soybean variety ‘Jiyu 47’ to investigate the differentially expressed proteins (DEPs) in soybean roots during the seedling stage based on the TMT proteomics analysis. Results of enrichment analyses based on a total of 468 DEPs revealed a coordinated expression pattern of proteins involved in various cellular metabolisms responding to drought stress in soybean roots. Our results showed that drought stress caused significant alterations in the expression of proteins involved in several metabolic pathways in soybean roots, including the carbohydrate metabolism, the metabolism of the osmotic regulation substances, and the antioxidant defense system (i.e., the glutathione metabolism). Increased production of reduced glutathione (GSH) enhanced the prevention of the damage caused by reactive oxygen species and the tolerance of the abiotic stress. The glutathione metabolism played a key role in modifying the antioxidant defense system in response to drought stress in soybean roots. Our proteomic study demonstrated that the soybean plants responded to drought stress by coordinating their protein expression during the vegetative stage, providing novel insights into the molecular mechanisms regulating the response to abiotic stress in plants.
