(Submitter supplied) Sorghum is an important crop often subjected to simultaneous high temperatures and drought in the field. We examined the gene expression response to heat and drought stress both individually, and in combination, with the aim of identifying important stress tolerance mechanisms.

(Submitter supplied) This study utilized next generation sequencing technology (RNA-Seq) to examine the transcriptome of sorghum plants challenged with osmotic stress and exogenous abscisic acid (ABA) to elucidate those genes and gene networks that contribute to sorghum's tolerance to water-limiting environments with a long-term aim of developing strategies to improve plant productivity under drought.

(Submitter supplied) Purpose: Circular RNAs (circRNAs) and microRNAs (miRNAs) play important roles in abiotic stress responses in plants. The aims of this study are to genome-widely identify the circRNAs, miRNAs and their targets in tomatoes at single heat, drought and their combination by high-throughput sequencing. Results: Following high-throughput sequencing, 765 miRNAs were identified in total with 335 conserved and 430 novel miRNAs in the 12 small-RNA libraries. more...

(Submitter supplied) The combined heat and drought stress influence the plant growth and development. Switchgrass is an economically important crop due to the availability of high biomass with little water and nutrient requirements. Earlier reports suggested that switchgrass growth and yield highly influenced by heat and drought. The mechanism behind heat and drought stress is not fully understood in switchgrass. This study has undertaken to analyze the epigenetic modification using ChIP-Seq analysis with the activation histone mark H3K4me3. more...

(Submitter supplied) Purpose: Increasing biomass yield and quality of feedstock have been a recent interest in switchgrass research. Despite the economic importance of switchgrass, increasing temperature and water deficit are limiting factors to the cultivation of bioenergy crops in the semi-arid areas. The effect of individual drought or heat stress has been studied separately in switchgrass. However, there is relatively limited or no report on the molecular basis of combined abiotic stress tolerance in switchgrass particularly the combination of drought and heat stress. more...

(Submitter supplied) Experimental research on the effects of abiotic stress over grapevine has mainly focused on water shortage. The adaptation of plants to stress is a complex response triggered by cascades of molecular networks involved in stress perception, signal transduction, and the expression of specific stress-related genes and metabolites. Approaches such as array-based transcript profiling allow assessing the expression of thousands of genes in control and stress tissues. more...

(Submitter supplied) Background: Drought stress is the major environmental stress that affects plant growth and productivity. It triggers in plants a wide range of responses detectable at different scales: molecular, biochemical and physiological levels. At the molecular level the response to drought stress results in the differential expression of several metabolic pathways. For this reason, explore the subtle differences existing in gene expression of drought sensitive and drought tolerant genotypes allows to identify drought-related genes that could be used for selection of drought tolerance traits. more...

(Submitter supplied) Populus euphratica is a natural population grown in semirid areas. The molecular response of the poplar to drought maintain to be elucided, especially at global genome level. We used Affymetrix poplar genome genechip microarrays to analyze the full transcript expression underlying different drought intensities and identified significantly differently expressed genes during this process.

(Submitter supplied) In the process of field production, crops are often affected by a variety of abiotic stresses, among which heat (HT) and drought (DR) stress are the most common co-stresses in summer. Although a large number of studies have been carried out on HT and DR stress respectively, little is known about how their combination (DH) affects plants. In this study, we investigated the responses of sweetpotato to HT, DR or DH stress by RNA-seq and DIA technologies, and set up a controlled experiment and quantified gene expression and protein concentrations from paired samples. more...
