A large number of spores from fruiting bodies can lead to allergic reactions and other problems during the cultivation of edible mushrooms, including Pleurotus eryngii (DC.) Quél. A cultivar harboring a sporulation-deficient (sporeless) mutation would be useful for preventing these problems, but traditional breeding requires extensive time and labor. In this study, using a sporeless P. eryngii ...
In Chinese cabbage, heading type is a key agricultural trait of significant economic importance. Using a natural microspore-derived doubled haploid plant, we generated self-crossed progeny with overlapping or outward curling head morphotypes. Sequencing-based bulked segregant analysis (Seq-BSA) revealed a candidate region of 0.52 Mb (A06: 1,824,886~2,347,097 bp) containing genes enriched for pl...
BACKGROUND Common diseases may be attributed to combinations of variant alleles, but there are few model systems where the interactions among such variants can be studied in controlled genetic crosses. While association studies are designed to detect common polymorphisms of moderate effect, new approaches are required to characterize the impact on disease of interactions among rare alleles. M...
Anthocyanin accumulation in various maize tissues plays important roles in plant growth and development. In addition, some color-related traits can be used as morphological markers in conventional maize breeding processes and purity identification of hybrid seeds. Here, we noticed that the leaf sheath color was controlled by a dominant gene, because purple (PSH) and green leaf sheaths (GSH) wer...
Genetic male sterility is controlled by one pair of ressesive allele (aa) in sugar beet. This trait is used in most breeding programes. The exsistance of the character in a line or population facilitates transfer of important trait to the breeding material (for example resistance to plant disease). Also, it is possible to increase genetic diversity of monogerm populations by using genetic ma...

Clubroot disease caused by Plasmodiophora brassicae is one of the major threats to Brassica crops. New clubroot resistant varieties Chinese cabbage (B. rapa ssp. pekinensis) have been developed through breeding, but underlying genetic mechanism resistance still unclear. In this study, two DH lines, clubroot-resistant Y635-10 and susceptible Y177-47 were crossed develop F2 population for fine ma...
