Wheat (Triticum aestivum L.) is one of the major grain crops, and heat stress adversely affects wheat production in many regions of the world. Previously, we found a heat-responsive gene named Lipid Transfer Protein 3 (TaLTP3) in wheat. TaLTP3 was deduced to be regulated by cold, ABA, MeJA, Auxin and oxidative stress according to cis-acting motifs in its(More)
It is important to estimate the genetic diversity between the parents for improving the heterosis of hybrid wheat. In this study, ISSR(inter-simple sequence repeat) marker was used to measure the genetic diversity within and among common wheat (Triticum aestivum L.), spelt (Triticum spelta L.), compactum (Triticum compactum Host.) and progeny of foreign(More)
In order to understand molecular basis of heterosis, mRNA differential display was used to analyze the differences in gene expression between seeds of 18 reciprocal hybrids and their 6 parents at 6th day after pollination. The relationship between gene expression patterns and heterosis was determined. Only bands that can be repeated in duplicate PCR were(More)
Two SSR molecular markers, genomic-SSR and EST (expressed sequence tagged)-SSR, were used to measure the genetic diversity among 18 accessions of common wheat with known pedigrees, which were collected from winter wheat production region in Northern China. In addtion, the genetic diversity revealed by pedigree, EST-SSR and genomic-SSR was also compared. The(More)
Simple sequence repeat (SSR) molecular marker was used to measure the genetic diversity of D-genome in 26 synthesized hexaploid wheat (AABBDD) introduced from CIMMYT. Twenty-three D-genome specific SSR primers were selected for PCR amplification, among which 22 primers can detect polymorphism. A total of 92 alleles were identified at 23 loci using the above(More)
Complete genomic and cDNA sequences of the Waxy gene encoding granule-bound starch synthase I (GBSSI) were isolated from the rye genome and characterized. The full-length rye Waxy genomic DNA and cDNA are 2767 bp and 1815 bp, respectively. The genomic sequence has 11 exons interrupted by 10 introns. The rye Waxy gene is GC-rich, with a higher GC frequency(More)
The availability of high-throughput genotyping technologies and microarray assays has allowed researchers to investigate genetic variations that influence levels of gene expression. Expression Quantitative Trait Locus (eQTL) mapping methods have been used to identify the genetic basis of gene expression. Similar to traditional QTL studies, the main goal of(More)
