Pyramiding of two rice bacterial blight resistance genes, Xa3 and Xa4, and a closely linked cold-tolerance QTL on chromosome 11.

We fine mapped the Xa4 locus and developed a pyramided rice line containing Xa3 and Xa4 R - alleles and a cold-tolerance QTL. This line will be valuable in rice breeding. Bacterial blight (BB) caused by Xanthomonas oryzae pv.

A correlation between tocopherol content and antioxidant activity in seeds and germinating seeds of soybean cultivars.

Background: Tocopherols are crucial lipid-soluble antioxidants and essential nutrients. There is increasing interest in the biofortification of crops with vitamin E for reducing micronutrient malnutrition. However, relatively little is known about the development of soybean cultivars with high levels of tocopherol through combined breeding.

Variation block-based genomics method for crop plants.

Background: In contrast with wild species, cultivated crop genomes consist of reshuffled recombination blocks, which occurred by crossing and selection processes. Accordingly, recombination block-based genomics analysis can be an effective approach for the screening of target loci for agricultural traits.

Results: We propose the variation block method, which is a three-step process for recombination block detection and comparison.

Introduction and nutritional evaluation of germinated soy germ.

Germinated soy germ (GSG) were developed and evaluated for their nutritional value. Separated soy germ was germinated at room temperature for 24h under running water. As germination progressed, the protein and fibre content of GSG increased slightly, while the lipid and carbon to nitrogen (C/N) ratio decreased; free amino acids including GABA increased considerably while free sugars decreased.
