Transcriptomic analysis of rapeseed (Brassica napus) flower buds exposure to male gametocide amidosulfuron

ABSTRACT: To reveal the possible molecular mechanism underpinning the male sterility induced by a sulfonyflurea herbicide amidosulfuron, a comparative transcriptome analysis between rapeseed under amidosulfuron folia spray and the contrast was conducted by using Illumina digital gene expression tag profiling technology (DGE). A total of 54 up-regulated and 119 down-regulated DETs (differentially expressed transcripts) were annotated by 357 GOs and 32 KEGG pathways, indicating that the reaction to amidosulfuron exposure is complicated in rapeseed. Some interesting GOs included (1) amino acid metabolite, (2) energy metabolite, (3) carbohydrate, lipid, protein metabolite, (4) cell division, growth and death, (5) stimulus and defense response, (6) chlorophyll and mitochondria, (7) hormone, (8) oxidoreductase, and (9) flavonoid biosynthesis. Expression of most genes in cell division, growth and death category, and flavonoid biosynthesis were down-regulated. Ethylene mediated signaling pathway was up-regulated, while auxin mediated signaling pathway was down-regulated. Stimulus and defense response were induced.

Exposure to ALS-inhibiting gametocide tribenuron-methyl affects pollen wall formation, lipid metabolism, chloroplast structure, and cell cycle in the flower buds of rapeseed

Project description:To reveal the possible molecular mechanism underpinning the male sterility induced by a sulfonyflurea herbicide tribenuron-methyl (TBM), a comparative transcriptome analysis between rapeseed plants exposed to a TBM solution of 0.2 mg/L concentration and the control (spray with water) was conducted by using Illumina digital gene expression tag profiling technology (DGE). A transcriptomic analysis of the flower buds of TBM treatment identified 208 up-regulated and 164 down-regulated differential expression genes in comparison with the control. It was showed by the genetic network that the main groups of GO terms including response to chemical and hormone stimulus (response to stress), developmental process (pollen wall and pollen exine formation), lipid metabolism, and cellular amino acid derivative biosynthesis process were significantly influenced by the TBM treatment. The cytological and transcriptomic alterations in the treated plants were in accordance with reduction of chlorophyll, photosynthetic rate, and elevation of ethylene release.

RNA-seq of two early-maturing rapeseed varieties treated with different cold stress

Project description:Oil rapeseed (Brassica napus L.) is a typical winter biennial plant, with high cold tolerance during vegetative stage. In recent years, more and more early-maturing rapeseed varieties were planted across China. Unfortunately, the early-maturing rapeseed varieties with low cold tolerance have higher risk of freeze injury in cold winter and spring. Little is known about the molecular mechanisms for coping with different low-temperature stress conditions in rapeseed. In this study, we investigated 47,328 differentially expressed genes (DEGs) of two early-maturing rapeseed varieties with different cold tolerance treated with cold shock at chilling (4°C) and freezing (−4°C) temperatures, as well as chilling and freezing stress following cold acclimation or control conditions. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis indicated that two conserved (the primary metabolism and plant hormone signal transduction) and two novel (plant-pathogen interaction pathway and circadian rhythms pathway) signaling pathways were significantly enriched with differentially-expressed transcripts. Our results provided a foundation for understanding the low-temperature stress response mechanisms of rapeseed. We also propose new ideas and candidate genes for genetic improvement of rapeseed tolerance to cold stresses.

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.

An immature high-oleic acid near-isogenic line of rapeseed

Project description:To identify differentially expressed proteins in a high-oleic acid rapeseed line, self-bred seeds (20 to 35 days after pollination) of a high- and a low-oleic acid rapeseed near-isogenic line (oleic acid contents of 81.4% and 56.2%, respectively) were used as raw materials for iTRAQ (isobaric tags for relative and absolute quantitation) analysis.

Physiological and transcriptomic responses to fishmeal-based diet and rapeseed meal-based diet in two strains of gibel carp (Carassius gibelio)

Project description:This study was conducted to investigate the effects of the rapeseed meal (RM) on two strains of gibel carp (A strain and F strain) and to explore whether two strains show the different molecular mechanisms to the fishmeal (FM) and rapeseed meal (RM). Transcriptomic analysis showed that amino acid metabolism, lipid metabolism and digestive system were three main biological processes affected by RM diet in both strains. The differentially expressed genes between strains were involved in amino acid metabolism, immune responses and lipid metabolism.

Proteome Analysis of rapeseed Cotyledons to Light

Project description:Among multiple factors, light plays a decisive role in the switch from heterotrophic to autotrophic growth. Under dark condition, the rapeseed hypocotyl extended quickly with an apical hook, yellow and folded cotyledon, and the glyoxysome assembling. Whereas under light, the hypocotyl extended slowly, the cotyledon unfolded and turned green. In this study, we performed proteome profiling analyses to show the differential molecular responses of Brassica napus cotyledons to light and dark and reveal metabolic adaptations in postgerminative seedling establishment. In both light and dark-grown conditions.
