Transcriptomic profiling of Linolenic Acid-responsive genes in ROS signalling from RNA-seq data in Arabidopsis

ABSTRACT: We describe the transcriptional profiles upon 1 mM linolenic acid (Ln) treatment in Arabidopsis cell suspension cultures. Ln is an important fatty acid in plant. We found that Ln treatment induced the expression of 533 genes and repressed the expression of 2501 gene. GO analysis indicated that most of those genes related to Reactive Oxygen Species signaling, abiotic and biotic stress responses, and/or Jasmonic Acid biosynthesis and signaling. This study provides basic information on how Ln regulates the gene expression and fulfils its role in abiotic and biotic stresses.

Linolenic acid (Ln) released from chloroplast membrane galactolipids is a precursor of the phytohormone jasmonic acid (JA). The involvement of this hormone in different plant biological processes, such as responses to biotic stress conditions, has been extensively studied. However, the role of Ln in the regulation of gene expression during abiotic stress situations mediated by cellular redox changes and/or by oxidative stress processes remains poorly understood. An RNA-seq approach has increased ...[more]

Wound inducible gene in rice leaves

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.

Jasmonic acid-responsive genes in rice leaves

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.

Transcriptomic analysis of the voz1 voz2 double mutant

Project description:Plants adapt to abiotic and biotic stresses by activating abscisic acid-mediated (ABA) abiotic stress-responsive and salicylic acid-(SA) or jasmonic acid-mediated (JA) biotic stress-responsive pathways, respectively. Although the abiotic stress-responsive pathway interacts antagonistically with the biotic stress-responsive pathways, the mechanisms that regulate these pathways remain largely unknown. In this study, we provide insight into the function of vascular plant one-zinc-finger proteins (VOZs) that modulate various stress responses in Arabidopsis. The expression of many stress-responsive genes was changed in the voz1voz2 double mutant under normal growth conditions. Consistent with altered stress-responsive gene expression, freezing- and drought-stress tolerances were increased in the voz1voz2 double mutant. In contrast, resistance to a fungal pathogen, Colletotrichum higginsianum, and to a bacterial pathogen, Pseudomonas syringae, was severely impaired. Thus, impairing VOZ function simultaneously conferred increased abiotic tolerance and biotic stress susceptibility. In a chilling stress condition, both the VOZ1 and VOZ2 mRNA expression levels and the VOZ2 protein level gradually decreased. VOZ2 degradation during cold exposure was completely inhibited by the addition of the 26S proteasome inhibitor, MG132, a finding that suggested that VOZ2 degradation is dependent on the ubiquitin/26S proteasome system. In voz1voz2, ABA-inducible transcription factor CBF4 expression was enhanced significantly even under normal growth conditions, despite an unchanged endogenous ABA content. A finding that suggested that VOZs negatively affect CBF4 expression in an ABA-independent manner. These results suggest that VOZs function as both negative and positive regulators of the abiotic and biotic stress-responsive pathways, and control Arabidopsis adaptation to various stress conditions.

OsJAR1M-bM-^HM-^Rrelated JA-inducible genes in osjar1 tos17 mutant rice leaves.

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.
