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:The plant hormone jasmonic acid (JA) plays a central role in plant defense responses.12-oxo-phytodienoic acid (OPDA) reductase 3 (OPR3) is a key enzyme in the JA synthesis pathway.To discover what facilitates defense functions in the JA pathway, we conducted a microarray analysis of OPR3 overexpressing rice plants (OPR3ox) and the wild-type Zhonghua 11.
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: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: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: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:The two-spotted spider mite, Tetranychus urticae, is one of the most significant mite pests in agriculture that can feed on more than 1,100 plant hosts, including model plants Arabidopsis thaliana and tomato, Solanum lycopersicum. In order to refine the involvement of jasmonic acid (JA) in mite-induced responses, we analyzed transcriptional changes in tomato JA signaling mutant defenseless1 (def-1) upon JA treatment and spider mite herbivory. We used microarray to assess global gene expression in Solanum lycopersicum def-1 cv. Castlemart upon jasmonic acid treatment and Tetranychus urticae attack.
Project description: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.
