(Submitter supplied) Rice has evolved regulatory programs and specialized cell types that allow the plant to withstand different environments. To understand how rice root systems cope with water stresses, we profiled translatomes (ribosome-associated mRNAs) and accessible chromatin of developmentally-defined root cell populations from well-watered and drained control (aerobic control), water deficit, waterlogged, fully submerged plants and recovery conditions.  Whereas, the waterlogging responses are limited to specific root domains, water deficit and submergence signatures are extensive, and mostly reversible after 1 day of  recovery, relative to control roots. more...

(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) To elucidate the epigenetic regulation of salt-responsive genes helps to understand the underlying mechanisms that confer salt tolerance in rice. However, it is still largely unknown how epigenetic mechanisms function in regulating the salt-responsive genes in rice and other crops at a global level. In this study, we mainly focused on dynamic changes in transcriptome and histone marks between rice leaf and root tissues during salt treatment by using RNA-seq and ChIP-seq approaches. 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) In this study, we used a cross-species network approach to uncover nitrogen (N)-regulated network modules conserved across a model and a crop species. By translating gene network knowledge from the data-rich model Arabidopsis (Arabidopsis thaliana, ecotype Columbia-0) to a crop, rice (Oryza sativa spp. japonica (Nipponbare)), we identified evolutionarily conserved N-regulatory modules as targets for translational studies to improve N use efficiency in transgenic plants.

(Submitter supplied) The root system is a crucial determinant of plant growth potential because of its important functions, e.g., acquisition of water and nutrients, structural support, and interaction with symbiotic organisms. Elucidating the molecular mechanisms of root development and functions is therefore necessary for improving plant productivity, particularly for crop plants including rice. As an initial step towards developing a comprehensive understanding of the root system, we performed a large-scale transcriptome analysis of the rice root via a combined laser microdissection and microarray analysis approach.

(Submitter supplied) Lateral Organ Boundary Domain (LBD) transcription factors are specific of plants and are involved in the control of development. One LBD clade is related to the control of root development (Coudert et al., 2013, Mol. Biol. Evol. 30, 569-572). Belonging to this clade, CROWN ROOTLESS 1 controls the initiation of crown roots in rice (Inukai Plant Cell, 17, 1387-1396, Liu et al., 2005, Plant J., 43, 47-56). 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...

We analyzed expression data obtained from leaves and roots of rice plants adapted to sufficient and limiting nitrate as well as after shifting them to low (reduction) and sufficient (induction) nitrate conditions.
