Transcriptomic analysis of maize developing earshoot from tropical maize hybrid genotypes native to Nigeria

ABSTRACT: Tropical maize genotypes are well known for their traits of late flowering and higher biomass. Carbon/Nitrogen balance in these genotypes is significantly different from temperate genotypes. Microarray analysis of gene expression changes occuring in developing earshoots was done and results were compared with the temperate genotype microarray analysis, previously conducted. A low yielding variety was used as a reference against three high yielding varities. Keywords: Genotype response Technical replicates, dye swaps, technical replicates of dye swaps, no biological replicates

Genetic factors that respond to N in maize leaf tissue

Project description:Genotype and nitrogen-dosage effect on maize leaves collected at V8 leaf stage B73 is a model maize genotype while Illinois high protein line (IHP) is a metabolic extreme selected for higher grain protein concentration. It is a well known fact that the leaves serve as source and earshoot as a sink. Microarray analysis of V8 leaf collected from B73 and IHP genotypes grown at vairable nitrogen applications. Keywords: Genotype and N-treatment response Technical replicates, dye swaps, technical replicates of dye swaps, no biological replicates

Transcriptomic analysis of maize developing earshoot, IBMRIL X IHP1 hybrid

Project description:Maize earshoot is a metabolic sink espcially related to nitrogen metabolism. Studies on the transcriptomic and metabolic changes occuring in earshoot can provide interesting answers about the nitrogen metabolic potential of the maize variety under study. Intermated B73 X Mo17 recombinant inbred lines (IBMRIL) belong to a predominantly used mapping population. Illinois high protein (IHP) line is a metabolic extreme with respect to nitrogen mebolism with around 30% seed protein. Developing earshoots from this genotype grown at nitrogen-deficient and nitrogen-sufficient conditions were sampled, processed and analyzed through microarray technology. IBMRIL population was crossed to IHP to find the allelic interaction related to nitrogen metabolism. Microarray experiment was conducted using the developing earshoots from IBMRIL X IHP1 lines that deffered in their grain yield significantly. Keywords: Yield response Technical replicates, dye swaps, technical replicates of dye swaps, no biological replicates

Transcriptome analysis of 16 DAP seeds of Illinois protein lines.

Project description:Illinois protein lines (IPL) comprise lines known as Illinois high protein (IHP), Illinois low protein (ILP), Illinois reverse-low protein (IRLP) and Illinois reverse-high protein (IRHP) lines. These lines represent over a century old experiment containing lines that represent various levels of nitrogen metabolism potential as a function of their grain protein concentration. Microarray experiment was conducted using 16 DAP seeds from the above mentioned four IPLs. Keywords: Genotype response Technical replicates, dye swaps, technical replicates of dye swaps, no biological replicates

Illinois protein lines (IPL) comprise lines known as Illinois high protein (IHP), Illinois low protein (ILP), Illinois reverse-low protein (IRLP) and Illinois reverse-high protein (IRHP) lines. These lines represent over a century old experiment containing lines that represent various levels of nitrogen metabolism potential as a function of their grain protein concentration.

Transcriptomic analysis of maize developing earshoot, B73 X Mo17 hybrid

2010-01-13 | E-GEOD-17932 | biostudies-arrayexpress

Project description:Expression profiling analyses for 5 maize inbreds and 4 hybrids, chosen to represent diversity in genotypes and heterosis responses, revealed a correlation between genetic diversity and transcriptional variation. This is a companion dataset to an Affymetrix profiling experiment (GEO Series GSE10236). Keywords: Genotype comparison series Expression profiling was used to study gene expression in aerial tissue from 11-day seedlings of maize. Three biological replicates were performed for nine different genotypes; B37, B73, B84, Mo17, Oh43, B37xB73, B84xB73, Oh43xB73 and Oh43xMo17.

Genome-wide expression profiling and phenotypic evaluation of European maize inbreds at seedling stage in response to heat stress

Project description:BACKGROUND: Climate change will lead in the future to an occurrence of heat waves with a higher frequency and duration than observed today, which has the potential to cause severe damage to seedlings of temperate maize genotypes. In this study, we aimed to (I) assess phenotypic variation for heat tolerance of temperate European Flint and Dent maize inbred lines, (II) investigate the transcriptomic response of temperate maize to linearly increasing heat levels and, (III) identify genes associated with heat tolerance in a set of genotypes with contrasting heat tolerance behaviour. RESULTS: Strong phenotypic differences with respect to heat tolerance were observed between the examined maize inbred lines on a multi-trait level. We identified 607 heat responsive genes as well as 39 heat tolerance genes. CONCLUSION: Our findings indicate that individual inbred lines developed different genetic mechanisms in response to heat stress. We applied a novel statistical approach enabling the integration of multiple genotypes and stress levels in the analysis of abiotic stress expression studies.

Gene expression study after 3 days of salt exposure in a Solanum tuberosum cultivar called Desirée

Project description:The molecular response to salt exposure was studied in the leaves of an S. tuberosum clone using cDNA microarray. Differentially expressed genes were classified according to their known or predicted function and their expression ratio as compared to the control. The major changes upon a 150 mM NaCl exposure in potato leaves occurred in the photosystem apparatus and Calvin cycle: many transcripts coding for proteins belonging to photosystems I and II and chlorophyll synthesis were repressed, whereas cell rescue and transcription factor-related genes were mostly up-regulated. A strong down-regulation of several functional categories including primary metabolism, detoxication apparatus and signal transduction was also observed. Gene expression has been followed three days after salinity treatment (150 mM NaCl). For each condition, 4 independent biological replicates were sampled. Dye-swaps were performed.
