(Submitter supplied) A rice transcription factor OsMYC2 plays important role in the regulation of defense responses in rice. To clarify the OsMYC2-responsive genes, we performed a microarray analysis using the Agilent Rice Oligo Microarray (44k, Agilent Technologies, Redwood City, CA, USA). As a result, many defense-related genes including pathogenesis-related (PR) genes were upregulated in the OsMYC2-overexpressing transgenic rice.

(Submitter supplied) Jasmonates is inductively produced as a major plant hormone responsible for defense reactions in plants against both biotic and abiotic stresses, such as pathogen infection and mechanical wounding. Jasmonoyl isoleucine is known to be a bioactive compound of jasmonate and plays a pivotal role for plant defenses. We identified OsJAR1−related JA-inducible genes in osjar1 tos17 mutant (osjar1-2) rice leaves 0 - 2 h after JA treatment using 44k microarray.

(Submitter supplied) Allantoin is a metabolic intermediate of purine catabolism that often accumulates in stressed plants. Recently, using Arabidopsis knockout mutants (aln) of ALLANTOINASE, we showed that this purine metabolite activates ABA production, thereby stimulating stress-related gene expression and enhancing seedling tolerance to abiotic stress. A detailed re-examination of the microarray data of an aln mutant (aln-1) not only confirmed increased expression of ABA-inducible genes, but also revealed altered expression of genes involved in jasmonic acid (JA) responses, likely under the control of MYC2, a master switch in the JA signaling pathway. more...

(Submitter supplied) Purine catabolism is regarded as a housekeeping function that remobilizes nitrogen for plant growth and development. However, emerging evidence suggests that certain purine metabolites might contribute to stress protection of plants. Here, we show that in Arabidopsis, the intermediary metabolite allantoin plays a role in abiotic stress tolerance via activation of abscisic acid (ABA) metabolism. The aln loss-of-function of ALN, encoding allantoinase, results in increased allantoin accumulation, genome-wide up-regulation of stress-related genes, and enhanced tolerance to drought-shock and osmotic stress in aln mutant seedlings. more...

(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 cell wall degrading enzyme LipA (Lipase/Esterase A) is a Type II secretion system secreted protein of Xanthomonas oryzae pv. oryzae (Xoo; the casual of bacterial leaf blight of rice). LipA is an Xoo virulence factor. However, LipA is a double edged sword for Xoo as it induces rice defense responses such as programmed cell death/hypersensitive response like reaction (HR) and callose deposition. more...

(Submitter supplied) Pathogens target phytohormone signalling pathways to promote disease. Plants deploy salicylic acid (SA) mediated defences against biotrophs. Pathogens antagonise SA immunity by activating jasmonate signalling, e.g. Pseudomonas syringae pv. tomato DC3000 produces coronatine (COR), a jasmonate (JA) mimic. This study found unexpected dynamics between SA, JA and COR and co-operation between JAZ jasmonate repressor proteins during DC3000 infection. more...

(Submitter supplied) Accumulating information indicates that plant disease resistance signaling pathway frequently interact with other pathways regulating developmental processes or abiotic stress responses. However, the molecular mechanisms of these types of crosstalk remain poorly understood in most cases. Here we report that OsWRKY13, an activator of rice resistance to both bacterial and fungal pathogens, functions as a convergent point of the crosstalk between pathogen-induced salicylate-dependent defense pathway and at least five other physiological pathways. more...

(Submitter supplied) Chitin is a major component of fungal cell walls and serves as a molecular pattern for the recognition of potential pathogens in the innate immune systems of both plants and animals. In plants, chitin oligosaccharides have been known to induce various defense responses in a wide range of plant cells including both monocots and dicots. We identified chitine oligosaccharide-responsive genes in suspension-cultured rice cells 6 and 24 h after treatment using rice 44k microarray.
