Long-lasting effect of jasmonic acid (JA) seedling treatment on the transcriptional response to JA challenge of five-week-old Arabidopsis thaliana (ecotype Col-0).

Project description:Treatment of Arabidopsis thaliana (ecotype Col-0) seedlings with jasmonic acid (JA) elicits long-term induced resistance (IR) against the chewing herbivore Spodoptera littoralis. We used RNA-seq to profile the transcriptional changes associated with this long-lasting JA-IR.

Whole genome bisulfite sequencing of five-week-old Arabidopsis thaliana (ecotype Col-0) plants from water and jasmonic acid treated seedlings.

Project description:Treatment of Arabidopsis thaliana (ecotype Col-0) seedlings with jasmonic acid (JA) elicits long-term induced resistance (IR) against the chewing herbivore Spodoptera littoralis. We used whole genome bisulfite-seq to profile the methylome associated with this long-lasting JA-IR.

Effect of jasmonic acid (JA) on the metabolome of actinobacteria

Project description:Actinobacteria are prevalent in the rhizosphere and phyllosphere of diverse plant species where they help to enhance tolerance of plants against biotic and abiotic stresses. Here, we show that the plant hormones jasmonic acid (JA) and methyljasmonate (MeJA) alter growth, development and specialized metabolism of Streptomyces. Exposure of Streptomyces coelicolor to JA or MeJA led to enhanced production of the polyketide antibiotic actinorhodin. JA also exhibited toxicity towards Streptomycetaceae, whereby streptomycetes were more tolerant to JA than members of the genus Streptacidiphilus. This defensive response was associated with amino acid conjugation of JA with glutamine (Gln)-JA as the most prevalent conjugant, while conjugates with Val, Tyr, Phe and Leu/Ile were identified after longer exposure to JA. Synthetic JA conjugates failed to activate antibiotic production and showed significantly reduced toxicity. Thus, our findings shed light on a previously unknown defense mechanism deployed by Streptomyces, with amino acid conjugation protecting against the toxic effects of plant hormones. This study adds to the growing body of evidence that plant hormones can have a significant impact on members of the plant microbiome by affecting their growth, development, and secondary metabolism.

Correlation between JA and jasmonic acid receptor COI1 in tobacco

Project description:JA-signaling in plants is manipulated by COI1 that recruits the protein complex perceiving JA signal . To determine JA correlated with the function of tobacco COI1, NtCOI1-silenced and control before and after MeJA treatment were analyzed using microarray chip.

Microarray analysis of rice plants exposed to jasmonic acid (JA)

Project description:In this study, integrated transcriptomics and proteomics approaches were applied to investigate the molecular responses of JA in the shoots of 7-days old rice (cv. Nipponbare) seedlings exposed to 5 micromolar JA for a period of 7 days. Based on the morphological alteration of JA-exposed rice seedlings, transcript profiling of rice genes was performed in seedlings using rice DNA microarray chip, and proteomics by 2-DGE. This systematic survey showed that JA triggers a chain reaction of altered gene and protein expressions involved in multiple cellular processes in rice growth and development and defense.

Whole genome tomato transcriptional response to jasmonic acid treatment and Tetranychus urticae herbivory [def-1]

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.

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.
