Project description:Jasmonic acid (JA) is involved in various developmental processes and defense responses against abiotic and biotic stresses. We identified JA-responsive genes in rice leaves 6-48 h after treatment using rice 44k microarray. Expression profiling in rice leaves treated with JA for 6, 12, 24 and 48 h was compared with that in the corresponding mock control using two-color method with two biological replicates.

Project description: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. We identified JA-inducible genes in the wild-type rice leaves 0 - 4 h after JA treatment using 44k microarray. Expression profiling in the wild-type rice leaves treated with jasmonic acid for 0.5, 1, 2, and 4 h was compared with that in the untreated wild-type rice leaves using two-color method with three biological replicates.

Project description:Jasmonic acid (JA) is involved in various developmental processes and defense responses against abiotic and biotic stresses. We identified JA-responsive genes in suspension-cultured rice cells 2-12 h after treatment using rice 44k microarray. Expression profiling in rice cells treated with JA for 2, 4, 6, 8 and 12 h was compared with that in untreated control using two-color method with two biological replicates.

Project description: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 OsJAR1M-bM-^HM-^Rrelated JA-inducible genes in osjar1 tos17 mutant (osjar1-2) rice leaves 0 - 2 h after JA treatment using 44k microarray. Expression profiling in the wild-type rice leaves treated with jasmonic acid for 0, 0.5, 1, and 2 h was compared with that in the osjar1 mutant leaves treated with jasmonic acid for 0, 0.5, 1, and 2 h using two-color method with three biological replicates.

Project description: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 1-12 h after treatment using rice 44k microarray. Expression profiling in rice cells treated with chitin oligosaccharide for 1, 2, 4, 6, 8 and 12 h was compared with that in untreated control using two-color method with two biological replicates.

Project description:To see the effect of overexpression of the bZIP transcription factor OsTGAP1, we compared the gene expression profiles in wild type rice cells and OsTGAP1-overexpressing rice cells. Expression profiling in the wild type rice cells and OsTGAP1-overexpressing rice cells treated with chitin oligosaccharide for 0, 6, and 24 h was compared using two-color method with four biological replicates.

Project description:The plant hormone jasmonic acid (JA) has been known as a signal molecule that is induced by various stresses and mediates plant defense responses. Rice O. sativa inductively produces variety of defensive compounds upon abiotic and biotic stress conditions, such as wounding and insect attack. We identified wound-inducible genes by comparison with transcriptomes between wounded and untreated wild-type rice leaves. Expression profiling in wild-type rice leaves treated by wounding for 0.5, 1, 2 and 4 h was compared with that in untreated control using two-color method with two biological replicates.

Project description:The plant hormone jasmonic acid (JA) has been known as a signal molecule that is induced by various stresses and mediates plant defense responses. Rice O. sativa inductively produces variety of defensive compounds upon abiotic and biotic stress conditions, such as wounding and insect attack. The bHLH transcription factor RERJ1 has previously been identified as JA-inducible factor whose expression is also rapidly induced by wounding. We identified RERJ1-dependent and wound-inducible genes by comparison with transcriptomes of wound treated wild-type and a Tos17-rerj1 defective mutant rice. Expression profiling between rice leaves of wild-type and tos17-rerj1 mutant treated by wounding for 0, 0.5, 1 and 2 h was compared using two-color method with two biological replicates.

Project description:Two-week old bread wheat seedlings hydroponically grown Hoagland solution were transferred to potassium (K+)-free conditions for 8 d, their root and leaf proteome profiles were assessed using iTRAQ proteome method, and NCBInr database combined with the recently published bread wheat genome information were used to analyze the identified protein species. Over 4,000 unique proteins were identified, 818 K+-responsive protein species showed significant abundance regulation. The most majority of the identified K+-responsive protein species had exact gene loci, and showed no global but tissue- and chromosome- dependent genome distributions. The identified protein species were associated with diverse functions and exhibited organ-specific differences. Most of identified protein species associated with hormone synthesis were the enzymes involved in the synthesis of jasmonic acid (JA). Allene oxide synthase (AOS), a key JA synthesis-related enzyme, was significantly induced in both root and leaf organs of K+-deficient wheat seedlings, and its overexpression in rice enhanced the tolerance to low K+ or K+ deficiency, increased contents of K+ and JA and transcription levels of some K+-responsive genes. However, rice AOS T-DNA inserted mutant (osaos) exhibited more sensitivity to K+ deficiency. K+ deficiency significantly increased abundance of a high affinity K+ transporter (TaAHAK1), TaAHAK1 transgenic rice seedlings markedly alleviated sensitivity to K+ deficiency, and K+ deficiency also upregulated expression of homologous OsHAK1 gene in TaAOS transgenic rice plants. These results suggested an essential role of JA in K+ deficiency and gave molecular insight into the responses of plant to K+ deficiency.
