(Submitter supplied) Plant stress response and tolerance mechanisms are controlled by diverse genes. Transcription factors have been implicated in drought tolerance under drought stress conditions. Identification of target genes of such transcription factors could offer molecular regulatory networks by which the tolerance mechanisms orchestrated. Previously, we generated transgenic rice plants with 4 rice transcription factors OsNAC5, 6, 9, and 10 under the root-specific promoter RCc3 that were tolerant to drought stress with less loss of grain yield under drought conditions. more...

(Submitter supplied) To understand the molecular mechanisms of drought tolerance, we performed ChIP-Seq and RNA-Seq analyses to identify direct target genes of the OsNACs using the RCc3:MYC-OsNACs roots. A total of 475 binding loci of 4 OsNACs were identified by cross-referencing the binding occupancy of OsNACs at promoter regions and expression levels of corresponding genes. The binding loci are distributed on promoter regions of 391 target genes that were directly up-regulated by OsNACs in four RCc3:MYC-OsNAC transgenic roots. more...

(Submitter supplied) OsNAC6 is a stress responsive NAC transcription factor in rice known as a regulator for the transcriptional networks of the drought tolerance mechanisms. However, little is known about the associated molecular mechanisms for drought tolerance. Here, we identified OsNAC6-mediated root structural adaptation such as increased root number and root diameter that was sufficient to confer drought tolerance. more...

(Submitter supplied) The AP2/ERF family is one of the plant-specific transcription factors (TFs) whose members have been associated with various developmental processes and stress tolerance. Here, we functionally characterized the drought-inducible OsERF48, a group Ib member of the rice ERF family that contains four conserved motifs, CMI-1, 2, 3 and 4. Transactivation assay in yeast revealed that the CMI-1 at the C-terminal end was essential for its transcriptional activity. more...

(Submitter supplied) Plants capture solar energy and atmospheric carbon dioxide (CO2) through photosynthesis, which is the primary component of crop yield, and needs to be increased considerably to meet the growing global demand for food. Environmental stresses, which are increasing with climate change, adversely affect photosynthetic carbon metabolism (PCM) and limit yield of cereals such as rice (Oryza sativa) that feeds half the world. more...

(Submitter supplied) NAD(H) and NADP(H) are crucial coenzymes and play important and distinguishable roles in all living organisms. NAD(H) is primarily involved in catabolic reactions, whereas NADP(H) participates in anabolic reactions, such as NADP(H)-dependent reductive anabolic pathways, signal transduction, and defense against oxidative stress. Hence, regulation of the intracellular balance of NAD(H) and NADP(H) is critical. more...

(Submitter supplied) To dissect the molecular mechanisms underlying drought tolerance (DT) in rice, transcriptome differences of a DT introgression line H471, the DT donor P28 and the drought sensitive recurrent parent HHZ under drought stress were investigated using deep transcriptome sequencing. Results revealed a differential constitutive gene expression prior to stress and distinct global transcriptome reprogramming among three genotypes under time-series drought stress, consistent with their differential genotypes and DT phenotypes.

We identified numerous downstream targets of OsHOX24 under desiccation stress and control by analyzing the comprehensive binding site map of OsHOX24 at whole genome level in rice.

(Submitter supplied) Rice is highly sensitive to drought, and the effect of drought may vary with the different genotypes and development stages. Genome-wide gene expression profiling was used as the initial point to dissect molecular genetic mechanism of this complex trait and provide valuable information for the improvement of drought tolerance in rice. Affymetrix rice genome array containing 48,564 japonica and 1,260 indica sequences was used to analyze the gene expression pattern of rice exposed to drought stress. more...

(Submitter supplied) Lamin proteins in animals are implicated in many nuclear functions, including chromatin organization, signaling transduction, gene regulation, and cell differentiation. Nuclear Matrix Constituent Proteins (NMCPs) are lamin analogues in plants, but their regulatory functions remain largely unknown. In this work, we report that OsNMCP1 positively regulates root growth and drought resistance through modulating chromatin state and expression levels of many genes functioning in root growth and stress resistance. more...
