Project description:Based our serial analysis of gene expression (SAGE) data from an elite Chinese super-hybrid rice (LYP9) and its parental cultivars (93-11 and PA64s) in three major tissue types at three different developmental stages, we obtained a much more comprehensive view of genes that related to rice heterosis and analyzed the potential effects of gene-expression difference on the heterosis of rice.These heterotic expression genes among different genotypes provided new avenues for exploring the molecular mechanisms underlying heterosis, including variable gene expression patterns. Keywords: Heterosis study by SAGE

Project description:Using a whole-genome oligonucleotide microarray designed based on known and predicted indica rice genes, we investigated transcriptome profiles in developing leaves and panicles of super hybrid rice LYP9 and its parental cultivar 93-11 and PA64s. We detected 22,266 expressed genes out of 36,926 total gene set collectively from seven tissues, including leaves at seedling and tillering stages, flag leaves at booting, heading, flowering, and filling stages, and panicle at filling stage. Clustering result showed that expression profiles between F1 and its parental lines were always more similar than that between the two parental lines. Out of the total gene set, 7,078 were shared by all sampled tissues and 3,926 (10.6%) were differentially-expressed genes (DG). As we divided DG into those between the parents (DGPP) and between the hybrid and its parents (DGHP), the comparative results showed that genes in the two categories, Energy metabolism and transport, were enriched in DGHP rather than in DGPP. The majority of genes were identified as additive expression, and non-additive expression only took a minority (0.53%-1.35%) of the total genes. In addition, we correlated the concurrence of DG and yield-related QTL, providing a potential group of genes as heterosis-related.

Project description:In order to study the effect of polyploidization on gene expression in the leaves of Eucalyptus urophylla, triploid obtained by sexual polyploidization and its diploid control were used as materials, and leaves at different growth stages of different ploidies were collected for transcriptome sequencing.

Project description:Comparative expression analysis between two highly salt-tolerant wheat lines, their parental lines, and a salt-sensitive line. The Chinese Spring (CS) line is salt sensitive. AJDAj5 and PhI are the two parental lines (with Chinese Spring background), and both have some salt-tolerance. W4909 and W4910 are two lines derived from crossing AJDAj5 and PhI, and both are more salt tolerant than either parental line.

Keywords: Heterosis study by SAGE We constructed nine SAGE libraries parallelly, including root at the first tillering stage, leaf at the milky stage of rice grain maturation, and panicle at the pollen-maturing stage of hybrid rice (LYP9) and its paternal lines (9311, PA64s).

We investigated transcriptome profiles in developing leaves and panicles of super hybrid rice LYP9 and its parental cultivar 93-11 and PA64s for seven tissues, and there are at least three independent replicates for each sample pair.
