AI Article Synopsis
- Olive flounder, a key fish species in Asia, has had a genetic linkage map developed using 180 microsatellites and 31 markers to enhance understanding of its genome.
- The study identified 24 linkage groups, matching the species' 24 chromosomes, with a total map distance of 1,001.3 cM and an average inter-locus distance of 4.7 cM.
- This linkage map can be valuable for mapping traits important to olive flounder and can support breeding efforts in fisheries and aquaculture.
Article Abstract
Olive flounder, Paralichthys olivaceus, is an important fish species in Asia, both for fisheries and aquaculture. As the first step for better understanding the genomic structure and functional analysis, we constructed a genetic linkage map for olive flounder based on 180 microsatellites and 31 expressed sequence tag (EST)-derived markers. Twenty-four linkage groups were identified, consistent with the 24 chromosomes of this species. The total map distance was 1,001.3 cM based on Kosambi sex-average mapping, and the average inter-locus distance was 4.7 cM. Linkage between the loci was identified by an LOD score of > or =3. This linkage map may be used to map quantitative trait loci associated with important traits of the species and may assist in breeding programs.

BrCYP71 encoding multifunctional oxidase was mapped using BSA-Seq and linkage analysis, and its function in stay-green of pak choi was verified through Arabidopsis heterologous transgenic experiment. Stay-green refers to the phenomenon that plant leaves remain green during senescence and even after death, which is of great significance for improving the commerciality of leafy vegetables during storage or transportation and extending their shelf life. In this study, we identified a stay-green mutant of pak choi and named it nye2.

Green rice leafhopper (GRH, Uhler) is a serious insect pest of rice in the temperate regions of Asia. Myanmar has a high genetic diversity and is located at the center of the origin of rice. To understand the genetic architecture of GRH resistance in Myanmar rice landraces, a genome-wide association study (GWAS) was performed using a diversity panel collected from diverse geographical regions.
