Project description:In this research, an array of 27,448 rice genes was used to elucidate gene expression in air-dried rice seedlings (lead and root) at various periods of treatment times. The analyses show that rice responds to drought stress mainly by down-regulating many biological processes including gene expression and regulation, protein phosphorylation, and cellular metabolism. Among strategies to actively adapt to drought, most significant are inducing protective molecules, which may be differentially regulated based on plant organs.

The analyses show that rice responds to drought stress mainly by down-regulating many biological processes including gene expression and regulation, protein phosphorylation, and cellular metabolism. Among strategies to actively adapt to drought, most significant are inducing protective molecules, which may be differentially regulated based on plant organs. A total of 20 chips was used for the microarray analysis. Total RNAs were extracted from leaf and root of rice seedlings that had undergone 0-12 hrs acute drought. Experiments were duplicated. The profiling was conducted with the Rice 3'-Tiling Microarray designed from 27,448 genes deposited at IRGSP, RAP1 database (http://rapdb.dna.affrc.go.jp/).

Project description:Regulated host cell death is part of a plant defense strategy against pathogens but it is also involved in accommodating certain beneficial root microbes. We have identified extracellular metabolites and intracellular metabolic signals that contribute to beneficial root fungal endophyte colonization, and uncovered a conserved cell death mechanism likely co-opted for establishing plant-endophyte symbiosis.

Project description:This submission comprises all raw sequencing reads generated and/or utilised in the analyses presented in the associated manuscript. The dataset comprises two independent experimental datasets, each designed to address distinct biological questions regarding the transcriptional behaviour of Fusarium oxysporum f. sp. lycopersici (Fol) under varying physiological and conditions of host-interaction. Experiment 1: Raw reads from Fusarium oxysporum f. sp. lycopersici (Fol) grown under four distinct nutrient and substrate conditions: minimal-media broth (Fol-Min-Media), granular microjammed (Gamborg's B5 Microjammed Granular hydrogel), monolithic agarose (Gamborg's B5 in conventional homogeneous agarose), and broth (Gamborg's B5 in liquid). This design enables dissection of transcriptional responses attributable to nutritional composition and substrate mechanical architecture. Experiment 2 Raw reads from a Microjammed Granular hydrogel-based tomato root–Fol infection system. Samples were collected at 12, 24, and 36 hours post-inoculation (hpi). At 12 hpi, tomato root, tip and fungal samples ex-planta surrounding the root surface were profiled. At 24 hpi, tomato root samples and spatially stratified fungal samples collected from ex-planta at the root-proximal and root-distal zones were profiled to characterise host-induced transcriptional rewiring in Fol in proximity to the root surface when the fungus is approaching a host plant before the physical contact. At 36 hpi, only tomato root/tip samples were collected to capture the plant transcriptional responses to infection after establishment of the fungal compatibility within the root.

Project description:In order to understand the mechanisms of Drought induced susceptibility (DIS) we’ve conducted a dual RNAseq experiment on rice infected tissues by Magnaporthe oryzae. At 4 days post inoculation tissues have been collected on mock inoculated and M. oryzae inoculated plants. Rice were conducted under two type of water regime: DIS Drought during three days before inoculation, NoDIS no drought before inoculation. RNAseq was conducted both on rice and fungal RNA.

Project description:Plant responses to drought stress require the regulation of transcriptional networks via drought responsive transcription factors, which mediate a range of morphological and physiological changes. AP2/ERF transcription factors are known to act as key regulators of drought resistance transcriptional networks; however, little is known about the associated molecular mechanisms that give rise to specific morphological and physiological adaptations. In this study, we functionally characterized the rice (Oryza sativa) drought responsive AP2/ERF transcription factor, OsERF71, which is predominantly expressed in the root meristem, pericycle, and endodermis. Overexpression of OsERF71 either throughout the entire plant or specifically in roots, resulted in a drought resistance phenotype at the vegetative growth stage, indicating that overexpression in roots was sufficient to confer drought resistance. The root specific overexpression was more effective in conferring drought resistance at the reproductive stage, such that grain yield was increased by 23-42% over wild type plants or whole-body overexpressing transgenic lines under drought conditions. OsERF71 overexpression in roots elevated the expression levels of genes related to cell wall loosening and lignin biosynthetic genes, which correlated with changes in root structure, the formation of enlarged aerenchyma and high lignification levels. Furthermore, OsERF71 was found to directly bind to the promoter of OsCCR1, a key gene in lignin biosynthesis. These results indicate that the OsERF71-mediated drought resistance pathway recruits factors involved in cell wall modification to enable root morphological adaptations, thereby providing a mechanism for enhancing drought resistance.
