Project description:Sampada and Sujata are two contrasting genotypes of Papaver somniferum that are contrasting in terms of their latex and alkaloid profiles. The major objective of the present study was to use a small-scale (750 target genes) microarray of P. somniferum for identification of genes that are differentially expressed in the capsule walls of the two contrasting genotypes, Sampada and Sujata. Nidarshana Chaturvedi and Mridula Singh made equal contribution as first authors to this data.

Project description:The aim of the present study was to investigate the response of rapeseed microspore-derived embryos (MDE) to osmotic stress at proteome level. The PEG-induced osmotic stress was studied in cotyledonary MDE of two genotypes: Cadeli (D), and Viking (V), which were previously reported to reveal contrasting leaf proteome responses under drought. 156 representative protein spots – obtained by 2D-DIGE – have been selected for MALDI-TOF/TOF, 63 proteins have been successfully identified and divided into 8 functional groups. Eight selected protein accumulation trends were validated by using qRT-PCR. Biomass accumulation in treated D was significantly higher (3-fold) than in V, so we can claim D as resistant to osmotic stress. Cultivar D displayed resistance strategy thanks to accumulation of proteins in energy metabolism, redox homeostasis, protein destination and signalling functional groups accompanied by high ABA and active cytokinins. In contrast, V protein profile displayed high requirements of energy (ATP) and nutrients with a significant number of stress-related proteins and cell structure changes accompanied by quick down-regulation for active CK content, SA, JA, GA20. MDE proteome profile is discussed together with leaf proteome results from our previous study (Urban et al., 2017, 30:152, J. Proteomics). We propose different mechanisms to cope with osmotic stress in the genotypes studied. This proteomic study is a first step to validate MDE as a suitable model for follow-up research on characterization of new crossings, and can be used for selection of resistant genotypes.

Project description:Poplars are known to be highly tolerant species to boron toxicity and accumulation. However, genes and molecular networks responsible in boron toxicity tolerance have not been investigated yet. Therefore, we performed a pot experiment with 20 black poplar clones collected from the vicinity of boron mines and polluted areas to investigate its potential role in phytoremediation and to select the most boron toxicity tolerant genotype. Trees were treated with irrigation water containing seven elevated boron concentrations from 0 to 160 ppm. Then a microarray based comparative transcriptome profiling was conducted to identify boron toxicity regulated genes responsible in defence responses of black poplar. The results of the study indicated that black poplar is quite suitable for phytoremediation of boron pollution. It could resist 15 ppm soil B content and < 1600 mg/kg boron accumulation in leaves which are highly toxic concentrations for almost all agricultural plants. Transcriptomics results of study revealed totally 1625 and 1419 altered probe sets under boron toxicity in leaf and root tissues, respectively. The highest induction were recorded for the probes sets annotated to tyrosine aminotransferase, ATP binding cassette transporters, glutathione S transferases and metallochaperone proteins. Strong up regulation of these genes attributed to internal excretion of boron into the cell vacuole and existence of detoxification processes in black poplar. Many candidate genes functional in signalling, gene regulation, antioxidation, boron uptake, transport and detoxification processes were also identified in the current study. This is the first transcriptomic study identifying boron toxicity regulated poplar genes and their potential role in boron toxicity tolerance. Total RNA used in microarray experiment was isolated from the leaves and roots of black poplar clone; N.92.237 which accumulated the highest amount of boron its tissues. Total RNA used in the microarray experiment was isolated from leaves and roots of three black poplar saplings grown in ~ 2 ppm (control) and ~ 15 ppm (toxic) soil B contents. RNA isolation was made according to Lithium chloride precipitation method described in Chang et al. (1993). These three isolated RNAs (biological replicates) for each tissue loaded onto three Affymetrix poplar Gene Chips (technical replicates). Totally, 12 GeneChips (2 tissues Ã? 2 different B treatment Ã? 3 biological replicates) were used for transcriptional analysis.

Project description:This study investigates the transcriptome and physiological responses of rapeseed to post-flowering temperature increases, providing valuable insights into the molecular mechanisms underlying rapeseed tolerance to heat stress. Two rapeseed genotypes, Lumen and Solar, were assessed under control and heat stress conditions in field experiments conducted in Valdivia, Chile. Results showed that seed yield and seed number were negatively affected by heat stress, with genotype-specific responses. Lumen exhibited a 9.3% average seed yield reduction, while Solar showed a 28.7% reduction. RNA-seq analysis of siliques and seeds revealed tissue-specific responses to heat stress, with siliques being more sensitive to temperature stress. Hierarchical clustering analysis identified distinct gene clusters reflecting different aspects of heat stress adaptation in siliques, with a role for protein folding in maintaining silique development and seed quality under high temperature conditions. In seeds, three distinct patterns of heat-responsive gene expression were observed, with genes involved in protein folding and response to heat showing genotype-specific expression. Gene coexpression network analysis revealed major modules for rapeseed yield and quality, as well as the trade-off between seed number and seed weight. Overall, this study contributes to understanding the molecular mechanisms underlying rapeseed tolerance to heat stress and can inform crop improvement strategies targeting yield optimization under changing environmental conditions.
