Project description:This SuperSeries is composed of the following subset Series: GSE32633: Jasmonic acid-responsive genes in suspension-cultured rice cells GSE32634: Jasmonic acid-responsive genes in rice leaves Refer to individual Series
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.
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.
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.

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:Analysis of leaves of wild-type and rice COI mutants treated with methyl jasmonate (MeJA). Results provide the role of rice COI on response to jasmonic acid.
Project description:A time course gene expression profiling of rice treated with various plant hormones (abscisic acid, gibberelin, auxin, brassinosteroid, cytokinin and jasmonic acid) was performed to obtain an overall signature of the rice transcriptome in response to each phytohormone.
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.
