Project description:The aim of this study was to investigate the role of strigolactones (SLs) in controlling tillering and their involvement as a signal for nitrogen status. RNA-seq analysis was performed on 18-day-old hydroponically grown Tad17 triple knock-out TILLING mutant plants (SL-deficient mutant) and WT-segregant plants, 8 days after introducing them to nitrogen limiting conditions. The experiment consisted of two different treatments: High Nitrogen (10 mM N) and Low Nitrogen (0.1 mM N). Each treatment included six biological replicates. Total RNA was extracted from pooled samples of four basal node sections per biological replicate. In this study, the basal node was defined as the 0.5 cm section from the base of the main shoot, comprising the apical meristem, lateral buds, leaf meristems, etc.
Project description:4 rice genotypes were sequenced for nitrogen usage under low and high nitrogen conditions to determine the uptake, and later combine with RNASeq data to figure which genes were modulated
Project description:To examine the effect of hasty KO mutation on miRNA expression, we performed miRNA-seq analysis using Arabidopsis Col-0 WT and hasty KO mutant that were grown under control and low nitrogen conditions.
Project description:his study investigates how Arabidopsis thaliana seeds integrate genetic and environmental stress during development. We analyzed wild-type (WT) and cruabc triple seed-storage-protein (SSP) mutants to test whether proteome rebalancing—the ability to maintain overall amino acid and protein composition despite loss of SSPs—persists under additional stress. Plants were subjected to low nitrogen, high nitrogen, or drought treatments applied exclusively during seed filling. We measured seed physiological traits, carbon and nitrogen content, fatty-acid composition, free and protein-bound amino acids, and performed DIA-based total proteomics.
Project description:DNA microarray analysis was used to profile gene expression in a commercial isolate of Saccharomyces cerevisiae grown in a synthetic grape juice medium under conditions mimicking a natural environment for yeast: High-sugar and variable nitrogen conditions. The high nitrogen condition displayed elevated levels of expression of genes involved in biosynthesis of macromolecular precursors across the time course as compared to low-nitrogen. In contrast, expression of genes involved in translation and oxidative carbon metabolism were increased in the low-nitrogen condition, suggesting that respiration is more nitrogen-conserving than fermentation. Several genes under glucose repression control were induced in low-nitrogen in spite of very high (17%) external glucose concentrations, but there was no general relief of glucose repression. Expression of many stress response genes was elevated in stationary phase. Some of these genes were expressed regardless of the nitrogen concentration while others were found at higher levels only under high nitrogen conditions. A few genes, FSP2, RGS2, AQY1, YFL030W, were expressed more strongly with nitrogen limitation as compared to other conditions. Set of arrays organized by shared biological context, such as organism, tumors types, processes, etc. Keywords: Logical Set
Project description:We performed ChIP-seq of histone modifications and RNA-seq in WT and kmt6 mutant Fusarium graminearum grown in high and low nitrogen conditions. Two replicates of RNA seq for WT and kmt6 strains at high and low nitrogen. Four histone modification ChIPs in WT and kmt6 mutant strains at high and low nitrogen, plus two histone modifications in a kmt6+ complemented strain at high nitrogen.
Project description:To understand the role of SL-signaling components in water stress response, we have carried out comparative expression analysis of the SL-response max2-3 mutant and WT plants under dehydration and well-watered (control) conditions. Aligent’s whole Arabidopsis Gene Expression Microarray (G2519F-021169, V4, 4x44K) was used.
