BACKGROUND Angiosperm mitochondrial genomes are more complex than those of other organisms. Analyses of the mitochondrial genome sequences of at least 11 angiosperm species have showed several common properties; these cannot easily explain, however, how the diverse mitotypes evolved within each genus or species. We analyzed the evolutionary relationships of(More)
A saturated map was constructed using SNP markers to fine-map a Brassica napus dominant locus for dwarf mutant onto a 152-kb interval of chromosome A09 containing 14 genes. Major dwarf loci in crops may play important roles in crop improvement and developmental genetics. The present study investigated and fine-mapped a Brassica napus dwarf-dominant locus(More)
Leaf colour regulation is important in photosynthesis and dry material production. Most of the reported chlorophyll-deficient loci are recessive. The dominant locus is rarely reported, although it may be more important than the recessive locus in the regulation of photosynthesis efficiency. During the present study, we mapped a chlorophyll-deficient(More)
Common cutworm (CCW) is one of the more serious leaf-feeding pests of soybean, causing significant yield losses in China. We have studied a sample (526 accessions) of the Chinese soybean germplasm population by association analysis using 233 polymorphic markers. Our aim was to detect quantitative trait loci (QTL) and corresponding alleles relating heritable(More)
Utilizing an innovative GWAS in CSLRP, 44 QTL 199 alleles with 72.2 % contribution to SIFC variation were detected and organized into a QTL-allele matrix for cross design and gene annotation. The seed isoflavone content (SIFC) of soybeans is of great importance to health care. The Chinese soybean landrace population (CSLRP) as a genetic reservoir was(More)
Bacterial blight, caused by Xanthomonas oryzae pv. oryzae (Xoo), is a serious disease in rice production worldwide. To understand the genetic diversity of bacterial blight resistance a population consisting of 175 indica accessions from nine countries was collected and detected their association between SSR (Simple Sequence Repeat) markers and resistance to(More)
Experimental error control is very important in quantitative trait locus (QTL) mapping. Although numerous statistical methods have been developed for QTL mapping, a QTL detection model based on an appropriate experimental design that emphasizes error control has not been developed. Lattice design is very suitable for experiments with large sample sizes,(More)
