Article Abstract
In this study, microsatellite loci in geese were initially screened, after which a multiplex PCR system was constructed and the genetic diversity and genetic structure of 40 samples from each of the three Huoyan goose populations in Liaoning were analyzed using the STR typing test. The results showed that 12 microsatellite loci were screened, and one quadruple PCR system, two triple PCR systems and one double PCR system were constructed with consistent and reliable reproducibility. A total of 90 alleles were detected in 120 samples, the number of alleles(Na), observed heterozygosity (Ho), expected heterozygosity (He) and polymorphic information content(PIC) of the three populations ranged from 5.083 to 6.083, from 0.149 to 0.184, from 0.555 to 0.577 and from 0.503 to 0.512.respectively, the populations present an unbalanced state, and the genetic diversity of three populations was highly polymorphic and highly inbred. The results of Principal Coordinates Analysis (PCoA) and genetic structure analysis showed that the genetic backgrounds of the three populations of Huoyan geese were similar, with close affinities and frequent gene exchanges.

Distinct evolutionary trajectories of subgenomic centromeres in polyploid wheat.

Background: Centromeres are crucial for precise chromosome segregation and maintaining genome stability during cell division. However, their evolutionary dynamics, particularly in polyploid organisms with complex genomic architectures, remain largely enigmatic. Allopolyploid wheat, with its well-defined hierarchical ploidy series and recent polyploidization history, serves as an excellent model to explore centromere evolution.

Background: Rare genetic variation provided by whole genome sequence datasets has been relatively less explored for its contributions to human traits. Meta-analysis of sequencing data offers advantages by integrating larger sample sizes from diverse cohorts, thereby increasing the likelihood of discovering novel insights into complex traits. Furthermore, emerging methods in genome-wide rare variant association testing further improve power and interpretability.

Retinitis pigmentosa (RP) affects around 1 in 4000 individuals and represents approximately 25% of cases of vision loss in adults, through death of retinal rod and cone photoreceptor cells. It remains a largely untreatable disease, and research is needed to identify potential targets for therapy. Mutations in 94 different genes have been identified as causing RP, including AGBL5 which encodes the main deglutamylase that regulates and maintains functional levels of cilia tubulin glutamylation, which is essential to initiate ciliogenesis, maintain cilia stability and motility.

Potato bolters are caused by excision of a transposon from the StCDF1.3 allele, resulting in a somatic mutant with late maturity. Somatic mutations during vegetative propagation can lead to novel genotypes, known as sports.

Insulin resistance is a heritable risk factor for many chronic diseases; however, the genetic drivers remain elusive. In seeking these, we performed genetic mapping of insulin sensitivity in 670 chow-fed Diversity Outbred in Australia (DOz) mice and identified a genome-wide significant locus (QTL) on chromosome 8 encompassing 17 defensin genes. By taking a systems genetics approach, we identified alpha-defensin 26 (Defa26) as the causal gene in this region.
