Project description:Salinity represses plant root growth, resulting in reduced biomass of agricultural plants. Little is known about how plants maintain root growth and development to counteract salt stress. SOS2-mediated PLT1/2 phosphorylation stabilizes PLT1/2, which is critical for root apical meristem maintenance under salt stress.

Project description:To understand affected genes by HDA19 and HDA5/14/15/18 under salinity stress conditions, hda19 and hda5/14/15/18 mutants and control (Col-0) plants were analyzed under normal and salinity stress conditions using Arabidopsis custom microarrays (GEO array platform: GPL19830).

Project description:Soybean's productivity is significantly compromised by soil salinity, but, like most plants, it has evolved a variety of mechanisms to aid its survival under environmental stress. The expression of many plant genes is altered by salinity stress. We used microarrays to detail the global programme of gene expression and identified distinct up or down-regulated genes between salinity stressed and non stressed soybean

Project description:We examined changes in steady-state transcript level in leaves of Arabidopsis plants subjected to salinity, heat stress and their combination by a transcriptome analysis of leaves. mRNA profiles of Arabidopsis plants subjected to salinity, heat stress and their combination were generated by RNA-Seq analysis, in triplicate, using an Illumina HiSeq2000.

Project description:In the present study, we compared transcriptional response to salinity between male and female individuals of Populus yunnanensis. We found that several functional groups of genes involved in important pathways were differentially expressed, including photosynthesis-related genes which were mainly up-regulated in males but down-regulated in females. This gene expression pattern is consistent with physiological observation that salinity inhibited photosynthetic capacity more in females than in males. In conclusion, our study provided molecular evidence of sexual differences in poplar salinity tolerance. Identified sex-related genes in salinity tolerance and their functional groups will enhance our understanding of sexual differences to salinity stress at the transcription level. 4 samples examined: males without salinity stress, males exposed to salinity stress, females without salinity stress and females exposed to salinity stress. Nine plants of each sex were exposed to each treatment, and RNA samples from the 9 individuals were pooled with equal proportion.

Project description:Micro RNAs (miRNAs) are a class of small endogenous RNAs conserved in eukaryotic organisms including plants. They suppress gene expression post-transcriptionally in many different biological processes. Previously, we reported salinity-induced changes in gene expression in transgenic Arabidopsis thaliana plants that constitutively expressed a pea abscisic acid-responsive (ABR17) gene. In the current study, we used a microarray to investigate the role of miRNA-mediated post-transcriptional gene regulation in these same transgenic plants in the presence and absence of salinity stress. We identified nine miRNAs that were significantly modulated due to ABR17 gene expression, and seven miRNAs that were modulated in response to salt stress. The target genes regulated by these miRNAs were identified using starBase (sRNA target Base) Degradome analysis and through 5' RNA Ligase Mediated-Rapid Amplification of cDNA Ends (RLM-RACE). Our findings revealed miRNA:mRNA interactions comprising regulatory networks of Auxin Response Factor (ARF), ARGONAUTE 1, (AGO1), Dicer-like proteins 1 (DCL1), Squamosa Promoter Binding (SPB), NAC, APETALA 2 (AP2), Nuclear Factor-Y (NFY), RNA binding proteins, Arabidopsis thaliana vacuolar phyrophosphate 1 (AVP1) and Pentatricopetide repeat (PPR) in ABR17 transgenic A. thaliana, which control physiological, biochemical and stress signalling cascades due to the imposition of salt stress. Our results are discussed within the context of the effect of the transgene, ABR17, and the roles miRNA expression may play in mediating plant responses to salinity.

Project description:Yield losses as a result of abiotic stress factors present a significant challenge for the future of global food production. While breeding technologies provide potential to combat negative stress-mediated outcomes over time, interventions which act to prime plant tolerance to stress, via the use of phytohormone-based elicitors for example, could act as a valuable tool for crop protection. However, the translation of fundamental biology into functioning solution is often constrained by knowledge-gaps. Photosynthetic and transcriptomic responses were characterised in young tomato (Solanum lycopersicum) seedlings in response to pre-treatment with a new plant health activator technology, M-bM-^@M-^XAlethea,M-bM-^@M-^Y followed by a subsequent 100 mM salinity stress. Salinity treatment led to a maximal 47% reduction in net photosynthetic rate 8 d following NaCl treatment. In Alethea pre-treated seedlings, sensitivity to salinity stress was markedly reduced during the experimental period. Microarray analysis of leaf transcriptional responses showed that while salinity stress and Alethea individually impacted on largely non-overlapping, distinct groups of genes, Alethea pre-treatment substantially modified the response to salinity. Alethea affected the expression of genes related to biotic stress, ethylene signalling, cell wall synthesis, redox signalling and photosynthetic processes. Since Alethea had clear effects on photosynthesis/chloroplastic function at the physiological and molecular levels, we also investigated the ability of Alethea to protect plants against methyl viologen, a potent generator of oxidative stress in chloroplasts. Alethea pre-treatment produced dramatic reductions in visible foliar necrosis caused by methyl viologen compared with non-primed controls. Tomato leaves from four groups of treated plants were harvested at a single point following treatment for RNA extraction and hybridization on Affymetrix microarrays. Plants came from two initial groups, pre-treated either with water (control) or the Alethea product. Equal numbers of plants from within these groups were subsequently treated either with water (control) or salinity (100 mM NaCl), generating 4 main experimental groups in a 2x2 factorial design. Samples were collected from 3 biological replicate experiments, and each sample included leaves pooled from 3 individual plants from each treatment group.

Project description:The res (restored cell structure by salinity) mutant exhibits a remarkable growth inhibition and morphological alterations in roots and leaves, which are suppressed when the mutant plants are exposed to salinity. The analysis of mutants like res may be very helpful in understanding how plants are able to coordinate the balance between growth and stress, a fundamental and not fully-understood question of important agronomical implications In order to understand the molecular basis of phenotype recovery and tolerance induced by salt stress in res mutant, we carried out a comparative transcriptomic analysis between res and WT plants. This analysis revealed a constitutive alteration of an important number of genes involved in different pathways in res mutant, and identified genes specifically overexpressed under salt stress and responsible of both maintaining plant growth and promoting stress tolerance in res mutant.
