Expression profiling using cDNA-AFLP is commonly used to display the transcriptome of a specific tissue or developmental stage. Here cDNA-AFLP was used to identify transcripts in a segregating F1 population of Phytophthora infestans, the oomycete pathogen that causes late blight. To find transcripts derived from putative avirulence (Avr) genes germinated cyst cDNA from F1 progeny with defined a...

High-temperature stress can cause serious abiotic damage that limits the yield and quality of rice. Heat tolerance (HT) during flowering stage rice is a key trait guarantee high stable under heat stress. HT complex regulated by multiple quantitative loci (QTLs); however, few underlying genes have been fine mapped cloned. In this study, F 2:3 population derived from cross between Huanghuazhan (H...

Abstract Background Plant height is an important plant characteristic closely related to yield performance of many crops. Reasonable reduction crops beneficial for improving and enhancing lodging resistance. Results In the present study, we described Brassica napus dwarf mutant bnd2 that was isolated using ethyl methanesulfonate (EMS) mutagenesis. Compared wild type (WT), exhibited reduced shor...

The utilization of heterosis in rice, maize and rapeseed has revolutionized crop production. Although elite hybrid cultivars are mainly derived from the F1 crosses between two groups of parents, named NCII mating design, little has been known about the methodology of how interacted effects influence quantitative trait performance in the population. To bridge genetic analysis with hybrid breedin...

Artistic diversiform leaf color is an important agronomic trait that affects the market value of ornamental kale. In the present study, genetic analysis showed that a single-dominant gene, Re (red leaf), determines the red leaf trait in ornamental kale. An F2 population consisting of 500 individuals from the cross of a red leaf double-haploid line 'D05' with a white leaf double-haploid line 'D1...

Resistance to soybean rust (SBR), caused by Phakopsora pachyrhizi Syd. & Syd., has been identified in many soybean germplasm accessions and is conferred by either dominant or recessive genes that have been mapped to six independent loci (Rpp1 -Rpp6), but No U.S. cultivars are resistant to SBR. The cultivar DT 2000 (PI 635999) has resistance to P. pachyrhizi isolates and field populations from t...
