Gene expression data for rice grain (Oryza sativa L.) aroma performed using bulk pools of aromatic and non-aromatic RILs derived from a cross between Pusa 1121 and Pusa 1342

ABSTRACT: Gene expression profile was studied to complement fine mapping studies. Genes co-located in the previously reported three aroma QTLs viz. qaro3.1, qaro4.1 and qaro8.1 were identified. Microarrays were used to study gene expression profile to reduce the number of up- and down regulated genes co-located within the reported aroma QTLs. These genes are the most suitable candidates for further validation studies and development of molecular markers to assist in Marker assisted Breeding for the development of new improved fragrant rice varieties. Six extreme aromatic RILs and six extreme non-aromatic RILs were identified on the basis of their sensory aroma scores. The RILs were pooled together to make two different bulk groups: aromatic bulk (VA) and non-aromatic bulk (VN). The two parents, Pusa 1121, the aromatic parent (VPA) and Pusa 1342, the non-aromatic parent (VRN) were also taken as two groups. RNA was isolated from fresh leaves after about 20-25 days of transplanting seedlings into experimental field, stage at which grain aroma develops. Four biological replicates (1-4) for each group were taken making a total of 16 samples.

Differentially expressed genes in different aromatic grapes at ripening stage

Project description:In order to investigate what differences exist in the aroma-regulated genes of grape varieties with different aromas, we established different aromatic grape varieties at the ripening stage and looked for the differential genes and their expression.

Aromatic dimer dehydrogenases from Novosphingobium aromaticivorans reduce aromatic diketones

Project description:Aromatic diketones are a major product of formic acid lignin depolymerization. Novosphingobium aromaticivorans can degrade these diketones, but the enzymes used in this process were unknown. We used RNA-Seq to identify aromatic dimer dehydrogenases as potential candidates for the initial reduction of the aromatic G-diketone, then verified this using in vitro enzyme assays.

Transcriptome profiling of reproductive stage flag leaves of wheat from drought susceptible parent WL711, drought tolerant parent C306 and drought susceptible and drought tolerant RIL bulks in irrigated and drought condition

Project description:The aim of the study was to identify candidate genes responsible for drought tolerance trait between a pair of wheat varieties ( WL711 and C306) and correspondng progeny bulks (10 drought susceptible RILs and 10 drought tolerant RILs) by combining QTLs analysis with expression analysis. Microarray analysis of RNA extracted from the flag leaves showed large number of differentially expressed genes. The number of differentially expressed genes was reduced to 37 on the basis of their occurance in a major QTL region (responcible for drought tolerance) detected in RIL population derived from WL711 and C306. RNA from the reproductive stage flag leaf of wheat in irrigated and drought condition of drought susceptible parent WL711, drought tolerant parent C306 and drought susceptible and drought tolerant RIL bulks were analysed in three different biological replications (A , B and C) making total twenty four samples

Transcription profiling of parental lines and bulked salt sensitive and salt tolerant RILs derived from 2 rice varieties

Project description:The aim of this study was to minimize the number of candidate genes responsible for salt tolerance between a pair of rice varieties (CSR27 and MI48) with contrasting level of salt tolerance by bulked segregant analysis of their recombinant inbred lines. Microarray analysis of RNA extracted from the tolerant and susceptible parents without and with stress showed 798 and 2407 differentially expressed genes, respectively. The number of differentially expressed genes was drastically reduced to 70 and 30, by pooling the RNAs from ten extreme tolerant and ten extreme susceptible RILs due to normalization of irrelevant differentially expressed genes between the parents. RNA from CSR27, MI48, tolerant bulk and susceptible bulk grown under control and salt stress conditions were analysed in two different biological replications (A and B) making total sixteen samples

Transcription profiling of 148 Arabidopsis recombinant inbred lines treated with Silwet solution to develop genetic markers and derive high-density haplotypes

Project description:The study of natural genetic variation for plant disease resistance responses is a complementary approach to utilizing mutants to elucidate genetic pathways. While some key genes involved in pathways controlling disease resistance, and signaling intermediates such as salicylic acid (SA) and jasmonic acid (JA), have been identified through mutational analyses, the use of genetic variation in natural populations permits the identification of change-of-function alleles, which likely act in a quantitative manner. Whole genome microarrays, such as Affymetrix GeneChips, allow for molecular characterization of the disease response at a genomics level and characterization of differences in gene expression due to natural variation. Differences in the level of gene expression, or expression level polymorphisms (ELPs), can be mapped in a segregating population to identify regulatory quantitative trait loci (expression QTLs, e-QTLs) affecting host resistance responses. We surveyed recombinant inbred lines (RILs) from a population derived from a cross of inbred Arabidopsis accessions Bayreuth-0 (Bay-0) and Shahdara (Sha) in order to map e-QTLs controlling ELPs. We treated vegetatively grown plants with either SA or a control solution (Silwet), and harvested the plants 28 hours after chemical treatment. We present Affymetrix GeneChip microarray expression data for 2 biological replications of the control (Silwet) samples for 148 RILs, plus replicated Bay-0 and Sha control samples grown at the same time as the RILs. These GeneChips were used to develop genetic markers and derive high-density haplotypes for the RILs
