Project description:Purpose: In this study we investigated the role of JASMONATE RESISTANT 1 (JAR1) and JAR1 mediated JA-Ile formation in drought stress tolerance in Arabidopsis thaliana. Methods: Global transcriptional changes in a newly generated over-expression line (JAR1-OE; 35S::JAR1-1-YFP)), a T-DNA insertion line in the JAR1 locus (jar1-11;SALK_034543), and wild-type Col-0 were investigated by RNA-seq analyses of rosette leaves from 32 day-old plant that were either well-watered (control) or not watered after day 18 (drought). Plants were grown on soil under long-day conditions Results: Under control conditions, using a stringent cut-off (DESeq, adjusted to FDR < 0.01 and LogFC ≥ 1), we found only four differentially expressed genes (DEGs) between jar1-11 and Col-0, all of them downregulated. By contrast, we found 339 DEGs between JAR1-OE and Col-0, of which 134 were downregulated and 205 were upregulated. A comparison of the RNA-seq data from Col-0 between control and drought conditions revealed 3401 DEGs, of which 2023 were down- and 1378 upregulated. By comparison, jar1-11 plants, which were most heavily affected by drought stress, showed a much higher number (6139 in total; 2616 up- and 3523 down-regulated) of DEGs, while the more drought-tolerant JAR1-OE line displayed a lower number (2025 in total; 971 up- and 1054 down-regulated) of DEGs. 2411 DEGs were found between Col-0 and jar1-11 under drought among which 966 genes showed a higher and 1445 genes a lower expression level in jar1-11. On the other hand, out of 998 DEGs found between Col-0 and JAR1-OE under drought, 737 genes showed a higher and 261 genes a lower expression level in JAR1-OE. Moreover, we found 391 DEGs counter-regulated between jar1-11 and JAR1-OE. Conclusion:RNA-seq analysis and additional experiments of plants under control and drought stress conditions provided insight into the molecular reprogramming caused by the alteration in JA-Ile content.

Project description:Nontargeted and targeted metabolomics measurements of abiotic stress responses in three-week-old Arabidopsis thaliana plants' rosette leaf tissue for Col-0 wild type plants and double/triple knockout mutants of aquaporins (pip2;1 pip2;2 and pip2;1 pip2;2 pip2;4) treated with drought, heat at different air humidities, or combined drought-heat stress at different air humidities. This experiment contains FT-ICR-MS measurements for 103 Arabidopsis thaliana rosette leaf samples covering three genotypes under six different environmental conditions. The three genotypes comprise the Col-0 wildtype and two loss-of-function mutants of aquaporins, a pip2;1 pip2;2 double mutant and a pip2;1 pip2;2 pip2;4 triple mutant (respective AGI locus identifiers: AT3G53420, AT2G37170, AT5G60660). The six conditions include control condition (well-watered, 22 °C, 70% relative air humidity), drought stress (one week without watering), heat stress without changing the absolute humidity of the ambient air (6 hours at 33 °C, 37% relative air humidity), heat stress with supplemented air humidity to maintain a constant vapor pressure deficit before and during the heat episode (6 hours at 33 °C, 84% relative air humidity), and the combinations of drought pretreatment with each of the two heat stress variants (one week of drought followed by 6 hours of heat stress). Samples from all conditions were harvested at the same time (within 15 min starting at 5 pm). For validation, GC-TOF-MS measurements were done for two genotypes (wildtype, double mutant) and two conditions (drought, control) on partially overlapping samples.
