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 new diabetic mouse strain, the Akita.PlGF knockout ((-/-)), was generated to study the role of placental growth factor (PlGF) in the pathogenesis of diabetic retinopathy (DR). PlGF deletion did not affect blood glucose but reduced the body weight of Akita.PlGF(-/-) mice. Diabetes-induced retinal cell death, capillary degeneration, pericyte loss, and(More)
Diabetic retinopathy (DR) is a leading cause of blindness in working age adults. The objective of this study is to investigate the effects of vascular endothelial growth factor receptor 1 (VEGFR1) blockade on the complications of DR. Experimental models of diabetes were induced with streptozotocin (STZ) treatment or Insulin2 gene mutation (Akita) in mice.(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)
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)
Definitive haematopoiesis occurs during the lifetime of an individual, which continuously replenishes all blood and immune cells. During embryonic development, haematopoietic stem cell (HSC) formation is tightly controlled by growth factors, signalling molecules and transcription factors. But little is known about roles of the cytochrome P450 (CYP) 2 family(More)
the study and reviewed and edited the manuscript. P.C. generated and provided the PlGF knockout mice. H.H. is the guarantor of this work and, as such, had full access to all the data in the study and takes responsibility for the integrity of the data and the accuracy of the data analysis. The online version reflects these changes.
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)
