ITPK4 is critical for root elongation under salt stress in Arabidopsis

Project description:Salt stress is one of the abiotic stresses that adversely affect plant growth and agricultural productivity all over the word. Root is the organ that immediately suffers salt stress in soil, and thus the ability of roots to adapt to high salinity is critical for salt stress tolerance in plants. During a long-term evolution, plants have developed a variety of strategies to respond to salt stress. The mechanisms of salt stress response are complicated and are stilly largely unknown. In this study, through the screening of Arabidopsis mutants that are sensitive to salt stress, we identified a mutant itpk4, that displayed reduced root growth, reduced seeds germination, and increased root hairs under salt stress compared with wild type plants. in future, the molecular mechanism underlying the role of ITPK4 in root elongation under high.

Calmodulin-binding transcription activator (CAMTA) 6 is a key regulator of Na+ homeostasis and salinity stress responses during early germination

Project description:In view of the continuous salinization of arable lands world-wide, there is an urgent need to better understand the mechanisms underlying plant responses to salt stress at different stages of their development. We investigated the role of calmodulin (CaM)-binding transcription activator 6 (CAMTA6) under salinity stress during early germination in Arabidopsis. These analyses suggest that ABA signaling is involved in CAMTA6-dependent salt-responsive gene expression, consistent with the ABA hyper-tolerance phenotype and the lack of HKT1 response to ABA and NaCl in the camta6 mutants.

Expression data in an Arabidopsis cytokinin-deficient mutant, ipt1,3,5,7 and its wild type plant (Col-0) under high salinity and control conditions.

Project description:To understand the role of cytokinins (CKs) in salt stress response, we have employed transcriptional profiling of the CK-deficient mutant, ipt1,3,5,7 and wild type plant, Col-0 under high salinity and control conditions to identify genes differentially expressed in ipt1,3,5,7 under salt stress and control conditions. Agilent's Whole Arabidopsis Gene Expression Microarray (G2519F, V4, 4x44K) was used.

Functional characterization of Arabidopsis WRKY15 overexpressor plants

Project description:Transcriptional profiling of Col4WT and WRKY15 overexpressor (WRKY15OE) plants, grown under controlled and mild salt stress conditions in order to identify molecular mechanisms underlying the increased salt stress sensitivity of WRKY15OE plants. Two genotypes x two conditions experiment, including Arabidopsis Col4WT and WRKY15OE plants grown on half-strength MS plant medium supplemented with 0 or 50 mM NaCl. Three biological replicates. Each sample was hybridized to one GenechipM-BM-. Arabidopsis Tiling 1.0R array.

Defective cytokinin signaling reprograms lipid and flavonoid gene-to-metabolite networks to mitigate high salinity in Arabidopsis

Project description:Cytokinin (CK) in plants regulates both developmental processes and adaptation to environmental stress. Arabidopsis histidine phosphotransfer ahp2,3,5 and type-B response regulator arr1,10,12 triple mutants are almost completely defective in CK signaling, and the ahp2,3,5 mutant was reported to be salt tolerant. Here, we demonstrate that the arr1,10,12 mutant is also more tolerant to salt stress than wild-type plants. A comprehensive metabolite profiling coupled with transcriptome analysis of the ahp2,3,5 and arr1,10,12 mutants was conducted to elucidate the salt tolerance mechanisms mediated by CK signaling. Numerous primary (e.g., sugars, amino acids and lipids) and secondary (e.g., flavonoids and sterols) metabolites accumulated in these mutants under both non-saline and saline conditions, suggesting that both pre- and post-stress accumulation of stress-related metabolites contribute to improved salt tolerance in CK-signaling mutants. Specifically, the level of oligosaccharides, amino acids [e.g., proline and gamma-aminobutyric acid], anthocyanins, sterols, and unsaturated triacyglycerols, were higher in the mutant plants than in wild-type plants. Notably, the reprograming of flavonoid and lipid pools was highly coordinated and concomitant with changes in transcriptional levels, indicating that these metabolic pathways are transcriptionally regulated by CK signaling. The discovery of the regulatory role of CK signaling on membrane lipid remodelling provides a greater understanding of CK-mediated salt tolerance in plants. This knowledge will contribute to the development of salt-tolerant crops with the ability to withstand salinity as a key driver to ensure global food security in the era of climate change.
