Barley embryo proteome analysis

Project description:To provide a more detailed insight into molecular changes in seeds exposed to the accelerated ageing process, we excised embryos and compared the differences in the proteome composition. Seeds collected from four contrasting locations were exposed to accelerated ageing. Next, embryos were dissected and analyzed in five biological replicates [1-5]. Sample description:CAS [1-5] - location n. 5 - (Caslav) - high yield, above average temperature and high rainfall; a significant decrease in germination energy after the accelerated ageing test. UHO [1-5] - location n. 11 (Uhersky Ostroh) - low yield, high temperature and low rainfall; very low decrease in germination energy after the accelerated ageing test.CH [1-5] - location n. 2 (Chrastava) - average yield, low temperature, very high rainfall; a significant decrease in germination energy after the accelerated ageing test.K [1-5] - location n. 8 (Krasne Udoli) - average yield, low temperature, average rainfall; a significant decrease in germination energy after the accelerated ageing test.

Transcriptome Profiling for Escherichia coli K12 wild type and ΔcsdA mutant before and after rifampicin-treatment

Project description:The cell cycle coordinates with growth to ensure suitable genome inheritance. The CsdA protein is a highly conserved, DEAD-box RNA helicase and assists RNA structural remodeling at low temperature. The absence of CsdA yields a severe growth defect manifested by increased doubling time, more extensive cell size, or slower colony growth at low temperature. Nevertheless, it is unknown how the lack of CsdA at low temperature affects the cell cycle and the causes of the yield of severe growth defect phenotypes. This work shows that the lack of CsdA results in incoordination of the cell cycle to growth at low temperature. We performed microarray analyses to compare the transcriptome profiles of ΔcsdA mutant with WT cell before and after rifampicin-treatment in LB to understand how the lack of CsdA at low temperature affects the cell cycle and the causes of the yield of severe growth defect phenotypes.

Transcriptome and physiological analysis of rapeseed tolerance to post-flowering temperature increase

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.

Photooxidative stress and light acclimation in the PSII antenna-deficient ch1 mutant

Project description:cea10-02_light - photooxidative stress - To characterize the metabolic pathways implicated in oxidative stress responses and in acclimation mechanisms in the ch1 mutant - The extracts are carried out starting from sheets of Arabidopis thaliana having pushed on compost in controlled conditions (light: 250 µmol.m-2.s-1, temperature: 22°C day 18°C night, moisture: 55%, photoperiod: 8:00 jour/16h night) during 4 and 8 weeks for respectively the Col0 genotype and the mutant ch1. The acclimatization of the plants is done during 48 H under an average luminous intensity (450 µmol.m-2.s-1, photoperiod 8:00), whereas the stress requires a strong luminous intensity (900 µmol.m-2.s-1, photoperiod 8:00) and low temperature (10°C day, 14°C night) also during 48 hours. 24 dye-swap - genotype comparison, treated vs untreated comparison

Gene expression profiling of flower and leaf of Cold-tolerant rice variety Stejaree45

Project description:To stabilize crop yield under low temperature stress conditions, it is important to improve stress tolerance in crops. Upon exposure to low temperature stress, many genes are induced and their products are thought to function as cellular protectants of stress-induced damages Therefore, responses of global gene expression profiles to cold stress was analyzed at the booting stage using the 60K Rice Whole Genome Microarray.

Expression data from fully-expanded leaflet of Bambara groundnut genotype (S19-3)

Project description:Low temperature stress in a number of African countries, such as Botswana, at night can effect the growth and development of bambara groundnut, leading to losses in potential crop yield. Therefore, we made an attempt to identify and analyze the genes and gene modules associated with low temperature stress response in bambara groundnut using the cross-species microarray technique, as bambara groundnut has no microarray chip, coupled with network-based analysis.

PIF7 is the master regulator of thermomorphogenesis in shade [ChIP-seq]

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.
