Abstract:
... KEY MESSAGE: In the soybean cultivar Suweon 97, BCMV-resistance gene was fine-mapped to a 58.1-kb region co-localizing with the Soybean mosaic virus (SMV)-resistance gene, Rsv1-h raising a possibility that the same gene is utilized against both viral pathogens. Certain soybean cultivars exhibit resistance against soybean mosaic virus (SMV) or bean common mosaic virus (BCMV). Although several SMV-r ...

Abstract:
... Spinach is a popular vegetable native to central and western Asia. It is dioecious with a pair of nascent sex chromosomes. The difficulties of working with the non-recombining sex determination region of XY individuals have hindered the progress toward sequencing sex chromosomes of most dioecious species. Here we present important advances toward characterizing the non-recombining sex chromosomes ...

Abstract:
... The domesticated gene Q on wheat chromosome 5A (5AQ) encodes an AP2 transcription factor. The 5AQ was originated from a G to A mutation in exon 8 and/or C to T transition in exon 10 and resulted in free-threshing and subcompact spike characters of bread wheat. The Q homeoalleles on 5B and 5D are either a pseudogene or expressed at a low level. Our previous study identified a mutant, named NAUH164, ...
