AI Article Synopsis
- This study created the first genetic linkage map for the brown planthopper (BPH), a major rice pest, using data from two backcross populations of three inbred strains.
- The final map features 518 genetic markers spread across 17 linkage groups, covering a distance of 1093.9 centimorgans, with an average of 2.3 centimorgans between markers.
- The research also identified a sex-linkage group, providing valuable resources for future genetic studies on BPH.
Article Abstract
In this study, we developed the first genetic linkage map for the major rice insect pest, the brown planthopper (BPH, Nilaparvata lugens). The linkage map was constructed by integrating linkage data from two backcross populations derived from three inbred BPH strains. The consensus map consists of 474 simple sequence repeats, 43 single-nucleotide polymorphisms, and 1 sequence-tagged site, for a total of 518 markers at 472 unique positions in 17 linkage groups. The linkage groups cover 1093.9 cM, with an average distance of 2.3 cM between loci. The average number of marker loci per linkage group was 27.8. The sex-linkage group was identified by exploiting X-linked and Y-specific markers. Our linkage map and the newly developed markers used to create it constitute an essential resource and a useful framework for future genetic analyses in BPH.

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.
