(Submitter supplied) Jasmonate (JA) is a plant hormone that controls trade-offs between plant growth and responses to biotic and abiotic stresses. Although recent studies uncover core mechanism for JA-induced responses in Arabidopsis thaliana, it remains elusive how plants attenuate those responses. We report here that a basic-helix-loop-helix type transcription factor named JA-INDUCIBLE MYC2-LIKE1 (JAM1) acts as a transcriptional repressor and negatively regulates JA signaling. more...

(Submitter supplied) The plant hormone jasmonate (JA) plays important roles in the regulation of defense responses in many plants. To clarify the response to JA in rice at gene expression level, we performed a microarray analysis using the Agilent Rice Oligo Microarray (44k, custom-made; Agilent Technologies, Redwood City, CA, USA). As a result, treatment of JA caused high upregulation of many defense-related genes including pathogenesis-related (PR) genes in rice. more...

(Submitter supplied) Phosphate (Pi) deficiency severely affects crop yield. Modern high yielding rice genotypes are sensitive to Pi deficiency whereas traditional rice cultivars are naturally compatible to low Pi ecosystems. However, the underlying molecular mechanisms for low Pi tolerance in traditional genotypes remain largely elusive. To delineate the molecular mechanisms for low Pi tolerance, two contrasting rice genotypes - Dular (low Pi tolerant) and PB1 (low Pi sensitive) - have been selected. more...

(Submitter supplied) In plants, basic helix-loop-helix (bHLH) transcription factors play important roles in the control of cell elongation. Two bHLH proteins, PACLOBTRAZOL RESISTANCE1 (PRE1) and Arabidopsis ILI1 binding bHLH1 (IBH1), antagonistically regulate cell elongation in response to brassinosteroid and gibberellin signaling, but the detailed molecular mechanisms by which these factors regulate cell elongation remain unclear. more...

(Submitter supplied) Subsequently to primary growth, most dicotyledonous plants undergo secondary growth leading to an increased diameter of growth axes. During secondary growth initiation in shoots, a cylindrical meristem, the vascular cambium, is established by the initiation of meristematic activity in interfascicular regions, a process that ultimately leads to the formation of a continuous cylinder of vascular tissue along the shoot axis. 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) To investigate how JA regulates Al-induced inhibition of root growth, a transcriptional analysis through RNAseq was performed by comparing the coi1-2 mutant and WT plants in the presence or absence of Al. In the absence of Al, 149 and 147 genes were up- and down-regulated, respectively, at least 2-fold in the roots of the coi1-2 mutant and WT plants. In the presence of Al, 1747 and 5838 genes were up- and down-regulated, respectively, in the roots of WT plants, while 1449 and 3773 genes were up- and down-regulated, respectively in the coi1-2 mutant. more...

(Submitter supplied) To identify genes that are regulated by MeJA and drought, global expression profilings were performed on panicles from Ubi1:AtJMT, drought-treated NT, and untreated NT plants. The underlying assumption of this approach was that high levels of MeJA produced either by overexpression of AtJMT in the transgenic panicles or by drought treatment in the NT panicles regulates genes that are involved in spikelet and/or panicle development. more...

(Submitter supplied) A major role of NINJA is to repress root jasmonate signalling and allow normal cell elongation.

(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) The current knowledge of drought stress transcriptomes in rice are mostly relying on comparative studies of diverse genetic background under drought. A more reliable approach is to use near-isogenic lines (NILs) with a common genetic background (Donar parent: Aday Sel, Recurrent parent: IR64), but contrasting levels of resistance to drought stress under initial exposure to water deficit. Here, we examined two pairs of NILs in IR64 background with contrasting drought tolerance. more...
