Project description:Upon virus infections, the transcriptomic profile of host plants markedly changes. The rapid and comprehensive transcriptional reprogramming is critical to ward off virus attack. To learn more about transcriptional reprogramming in tobamovirus-infected pepper leaves, we carried out transcriptome-wide RNA-Seq analyses of pepper leaves following Obuda pepper virus (ObPV) and Pepper mild mottle virus (PMMoV)-inoculations.

Project description:Plants experience a wide array of environmental stimuli to form a memory of adversity. Histone modification plays roles in plant stress memory, of which the mechanisms of H3K4me3 of low temperature memory in plants are poorly understood although H3K4me3 is a key histone modification. Combined with phenotypic analysis, chip-seq, and transcriptome analyses were performed to investigate the potential H3K4me3 contributions for different phases of recurring cold stresses Arabidopsis plants. Chromatin immunoprecipitation DNA-sequencing (ChIP-seq) for H3K4me3 in different low temperature stress.

Project description:Flavonoid biosynthesis in grape berry skin is affected by environmental factors such as light and temperature. However, the components of the light-signaling and low-temperature-induced ABA signaling networks related to flavonoid accumulation in grape berry skin have not been fully elucidated. To clarify details of the possible light- and ABA-related signal transduction networks, we performed comprehensive transcriptome analysis using grape berries cultured under different light and temperature conditions. We identified 40 light-inducible genes, 55 low-temperature-inducible genes, and 34 genes induced by light plus low temperature.

Project description:We used solexa sequencing technology to analysis transcriptome of tobacco seedings under low potassium stress for 6 h,12 h and 24h treatment. Further analysis suggested that 732 differentially expressed genes (DEGs) were up-regulated and 302 DEGs were down-regulated after potassium deficiency. Our results provided comprehensive analysis of gene regulatory network under low potassium stress of tobacco seedings.

We then performed gene expression profiling analysis using data obtained from RNA-seq of different low temperature treatments.

Project description:The size and shape of plant organs are highly responsive to environmental conditions. The plant's embryonic stem, or hypocotyl, displays phenotypic plasticity, in response to light and temperature. The, hypocotyl of shade avoiding species elongate to outcompete neighbouring plants and secure access to sunlight. Similar elongation occurs in high temperature. PHYTOCHROME-INTERACTING FACTORS (PIFs) family transcription are known to be importenet players in these responses. However, it is poorly understood how environmental light and temperature interact to affect plants development. We found that low R/FR combined with warm temperature produces a synergistic hypocotyl growth response that dependent on PIF7 and the hormone auxin. We demonstrate that additional, unknown factor/s must be working downstream of the phyB-PIF-auxin module. As shade responses are known to affect yield, susceptibility to pathogens, and fruit quality in many species, our findings will improve the predictions of how plants will respond to increased ambient temperatures when grown at high density, a condition in which mutual shading occurs.

Project description:During maturation seeds acquire several physiological traits to enable them to survive drying and disseminate the species. The maternal environment during maturation can influence seed quality. RNA-seq analyses of the embryo and the endosperm of seed matured ex planta under standard or stressful condition (high temperature and/or dim light) will underly how light and temperature and a combination of both have an impact on the molecular mechanisms governing seed quality at harvest.

Project description:Thermosensitive genic male sterile (TGMS) lines and photoperiod-sensitive genic male sterile (PGMS) lines have been successfully used in hybridization to improving rice yields. The molecular mechanisms underlying male sterility transitions in most PGMS/TGMS rice lines are unclear, but in the recently developed TGMS-Co27 lines which is based on co-suppression of a UDP-glucose pyrophosphorylase gene (Ugp1). UGPase protein accumulates in TGMS-Co27 florets at low temperatures and temperature-sensitive splicing is involved in its sterility transitions.However, details of the molecular mechanisms involved are unknown. we use microarrays to compare transcriptomic profiles during the meiosis-stage of flower development in TGMS-Co27 and wild-type (H1493) plants grown at high and low temperatures. The detected differences in expression profiles provide further understanding of the regulatory networks underlying flower development generally, identify genes involved in the TGMS process in TGMS-Co27 and may provide reference data for analyses of molecular mechanisms underlying sterility transitions in other PGMS/TGMS rice lines. Meiosis-stage inflorescences were used for this study because pollen mother cells (PMCs) of TGMS-Co27 plants begin to degenerate at this stage. Samples from H1493 grown at high temperature, TGMS-Co27 grown at high temperature, H1493 grown at low temperature and TGMS-Co27 grown at low temperature were harvested to compare the difference between fertile and sterile rice lines.
