(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 ROOT LESS 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) 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. 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) 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) 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.

(Submitter supplied) Crown roots constitute the main part of the rice root system. Several key genes involved in crown root initiation and development have been identified by genetics and functional genomics approaches. Nevertheless these approaches are impaired by gene function redundancy and mutant lethality. To overcome these limitations, genome-wide transcriptome analysis can help to identify genes involved in crown root formation and early development. more...

(Submitter supplied) Plasma membrane NADPH oxidases (NOXs) are major producers of reactive oxygen species (ROS) in plant cells under normal growth and stress conditions. Rice NOXs have multiple homologs but their functional mechanisms are largely unknown. We used microarrays to detail the global gene expression profiles in rice wild-type (WT, Dongjin) and a mutant osnox2 which loss the functions of OsNOX2 protein under drought and identified distinct classes of genes between the two type rice plants under both normal growth and drought stressed conditions.

(Submitter supplied) Potassium (K+) is one of the most important nutrient ions in plant cells and play crucial roles in many plant physiological and developmental processes. K+ deficiency is the common abiotic stress in natural environment, which inhibits plant growth and reduces production of crops. We used microarrays to analyse the transcriptomic changes in rice roots after suffering K+ starvation at different times. more...

(Submitter supplied) Autotoxicity plays an important mechanism in regulating plant productivity. Ferulic acid (FA) is phytotoxic and was identified in extracts and residues of rice plants as a candidate for rice allelochemicals. To help characterize the autotoxicity mechanism of rice, we present the first large-scale, transcriptomic analysis of rice root responses to ferulic acid.

(Submitter supplied) Despite the major physiological dissimilarities between roots and their tips, differences in their gene expression profiles remain largely unexplored. In this research, the transcriptome of rice (Oryza sativa L. subsp. Japonica) mature root tissue and root tips was monitored using mRNA-Seq at 2 time points. Almost 50 million 76 bp reads were mapped onto the rice genome sequence, differential expression patterns between tissues and time points were investigated and at least 1,006 novel transcriptionally active regions (nTARs) were detected to be expressed in rice root tissue. more...

(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) Several metals are essential nutrients for plants but metals are toxic in excess, deleteriously affecting crop yield and quality. Various kinds of genes involved in metal homeostasis have been investigated in detail over the past few decades and the mechanisms of how metals are absorbed from soil and distributed in plants have been elucidated. However, numerous genes related to metal homeostasis remain to be investigated and a comprehensive analysis of the expressions of these genes is required. more...
