Project description:Salinity stress is a major problem affecting plant growth and crop productivity. While plant biostimulants have been reported to be an effective solution to tackle salinity stress in different crops, the key genes and metabolic pathways involved in these tolerance processes remain unclear. This study focused on integrating phenotypic, physiological, biochemical and transcriptome data obtained from different tissues of Solanum lycopersicum L. plants (cv. Micro-Tom) subjected to a saline irrigation water program for 61 days (EC: 5.8 dS/m) and treated with a combination of protein hydrolysate and Ascophyllum nodosum-derived biostimulant, namely PSI-475. The biostimulant application was associated with the maintenance of higher K+/Na+ ratios in both young leaf and root tissue and the overexpression of transporter genes related to ion homeostasis (e.g., NHX4, HKT1;2). A more efficient osmotic adjustment was characterized by a significant increase in relative water content (RWC), which most likely was associated with osmolyte accumulation and upregulation of genes related to aquaporins (e.g., PIP2.1, TIP2.1). A higher content of photosynthetic pigments (+19.8% to +27.5%), increased expression of genes involved in photosynthetic efficiency and chlorophyll biosynthesis (e.g., LHC, PORC) and enhanced primary carbon and nitrogen metabolic mechanisms were observed, leading to a higher fruit yield and fruit number (47.5% and 32.5%, respectively). Overall, it can be concluded that the precision engineered PSI-475 biostimulant can provide long-term protective effects on salinity stressed tomato plants through a well-defined mode of action in different plant tissues.

Project description:Global warming and heat stress belong to the most critical environmental challenges to agriculture worldwide, causing severe losses of major crop yields. In present study we report that the endophytic bacterium Enterobacter sp. SA187 protects Arabidopsis thaliana to heat stress. To understand the mechanisms at molecular level we performed RNA-seq

Project description:CuZn-superoxide dismutase (CuZn-SOD) and ascorbate peroxidase (APX) constitute first line of defence against oxidative stress. In the present study, PaSOD and RaAPX genes from Potentilla atrosanguinea and Rheum australe, respectively were overexpressed individually as well as in combination in Arabidopsis thaliana. We performed RNA-seq analysis of wild type and transgenic Arabidopsis thaliana overexpressing CuZn-SOD, APX and CuZn-SOD + APX under control and salt stress

Project description:Phototropins are plasma membrane‐associated photoreceptors of blue light. Arabidopsis thaliana genome has two genes, PHOT1 and PHOT2, encoding two phototropins that mediate phototropism, chloroplast positioning and stomatal opening. They are well characterized in terms of photomorphogenetic processes, but so far little was known about their involvement in photosynthesis and response to stress factors triggering oxidative stress and cell death. This work fills the gap in our understanding of PHOT1 and PHOT2 involvement in these processes. We used UV-C treatment to promote oxidative stress and cell death in Arabidopsis thaliana wild-type (Col-0 gl1), phot1, phot2 and phot1/phot2 mutants. Using RNAseq we identified genes differentially expressed in phot mutants, in comparison to the wild-type, in both non-stress conditions and after UV-C stress.

Project description:The mechanism by which plants regulate channeling of photosynthetically derived electrons into different areas of chloroplast metabolism remains obscure. In higher plants, these electrons are made accessible to stromal enzymes, or cyclic electron flow, as reduced ferredoxin (Fd), or NADPH. We investigated how the specific loss of an Arabidopsis (Arabidopsis thaliana) ferredoxin:NADPH reductase (FNR) isoprotein affected channeling of photosynthetic electrons into NADPH and Fd dependent metabolism. Affymetrix gene chip comparison of transcript changes in these mutants against two different ecotype backgrounds indicates that stress signaling is perturbed, and experiments revealed that the mutants are more susceptible to oxidative stress. Keywords: mutant wild type transcript profile comparison
