Project description:Three rice major tissues, namely flag leaf, shoot and panicle, were involved in this study. Each tissue had two kinds stress treatment, drought and high salinity, in 3 different time courses. For drought treated samples, an additional water recovery was applied. Each experiment had three replicates. Keywords: Comparison of gene expression in three tissues with stress treatment and without treatment

Each experiment had three replicates. Keywords: Comparison of gene expression in three tissues with stress treatment and without treatment To globally elucidate potential genes involved in drought and high-salinity stresses responses in rice, an oligomer microarray covering 37,132 genes including cDNA or EST supported and putative genes was applied to study the expression profiling of shoot, flag leaf, and panicle under drought or high-salinity treatment. Three rice major tissues, namely flag leaf, shoot and panicle, were involved in this study. Each tissue had two kinds stress treatment, drought and high salinity, in 3 different time courses. For drought treated samples, an additional water recovery was applied. Each experiment had three replicates.

Project description:In this study, RNA-Seq was used to reveal the differences of molecular pathways in hepatopancreas of O. niloticus adapated to water with salinity of 8 or 16 practical salinity (psu), respectively, with fish at freshwater as the control,. Significantly changed pathways were mainly related to lipid metabolism, glucose utilization, protein consumption, osmotic regulation, signal transduction and immunology. Based on the tendencies from freshwater to 8 or 16 psu, the differentially expressed gene unions were categorized into eight unique models, which were further classified into three categories which were constant-change (either keep increasing or decreasing), change-then-stable and stable-then-change. In constant-change category, steroid biosynthesis, steroid hormone biosynthesis, fat digestion and absorption, complement and coagulation cascades were extremely significantly affected by ambient salinity (P < 0.01), indicating that these pathways play pivotal roles in molecular response to salinity acclimation from freshwater to saline water in O. niloticus, and should be the main research focus in the future. In change-then-stable category, ribosome, oxidative phosphorylation, peroxisome proliferator-activated receptors (PPAR) signaling pathway, fat digestion and absorption changed significantly with ambient increasing salinity (P < 0.01), showing these pathways were sensitive to environmental salinity variation, but had a response threshold, and would stop changing once salinity exceeds the threshold. In stable-then-change category, protein export, protein processing in endoplasmic reticulum, tight junction, thyroid hormone synthesis, antigen processing and presentation, glycolysis/gluconeogenesis and glycosaminoglycan biosynthesis - keratan sulfate were the top changed pathways (P < 0.01), suggesting that these pathways were not sensitive to salinity variation, but these pathways will respond significantly under salinity exceeding a certain level. The pathways and genes reported in this study laid on a solid foundation for future studies in understanding the underlying mechanism for salinity adaptation of freshwater fish.

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.
