Article Abstract
is a popular edible mushroom that is cultivated worldwide. Due to its secondary homothallic nature, cultivated strains have low genetic diversity, and breeding novel strains is challenging. The aim of this study was to investigate the genetic diversity and population structure of globally collected . strains using simple sequence repeat (SSR) markers. strains were divided based on genetic distance-based groups and model-based subpopulations. The major allele frequency (MAF), number of genotypes (NG), number of alleles (NA), observed heterozygosity (HO), expected heterozygosity (HE), and polymorphic information content (PIC) were calculated, and genetic distance, population structure, genetic differentiation, and Hardy-Weinberg equilibrium (HWE) were assessed. Strains were divided into two groups by distance-based analysis and into three subpopulations by model-based analysis. Strains in subpopulations POP A and POP B were included in Group I, and strains in subpopulation POP C were included in Group II. Genetic differentiation between strains was 99%. Marker AB-gSSR-1057 in Group II and subpopulation POP C was confirmed to be in HWE. These results will enhance . breeding programs and support the protection of genetic resources.

Population genetics plays a critical role in creating policies for managing fisheries, conservation, and development of aquaculture. The golden snapper, Lutjanus johnii (Bloch, 1792), is a highly commercial and aquaculture important snapper species. This study used mitochondrial markers D-loop (151 specimens) and Cytochrome b (Cyt-b, 120 specimens) from 10 populations, including populations from the east South China Sea, the west South China Sea and the Strait of Malacca to investigate the genetic diversity, population connectivity, and historical demography of L.

Background: Hearing loss (HL) is one of the most common congenital anomalies and is a complex etiologically diverse condition. Molecular genetic characterization of HL remains challenging owing to the high genetic heterogeneity. This study aimed to screen for potential disease-causing genetic variations in a cohort of Indian patients with congenital bilateral severe-to-profound sensorineural HL.

Polyploidy is an important driver of the evolution and diversification of flowering plants. Several studies have shown that established polyploids differ from diploids in floral morphological traits and that polyploidization directly affects these traits. However, for floral scent, which is key to many plant-pollinator interactions, only a few studies have quantified differences between established cytotypes, and the direct effects of polyploidization on floral scent are not yet known.

Background: The chaperoning system, which is responsible for protein homeostasis, plays a significant role in cardiovascular diseases. Among molecular chaperones or heat shock proteins (HSPs), the HSP40 family, the main co-chaperone of HSP70, remains largely underexplored, especially in ischemic heart disease (IHD) risk.
Materials And Results: We genotyped 834 IHD patients and 1,328 healthy controls for three SNPs (rs2034598 and rs7189628 DNAJA2 and rs4926222 DNAJB1) using probe-based real-time PCR.

Epinephelus tukula is an economically important aquaculture animal, and a major parent in grouper crossbreeding. To better preserve and exploit E. tukula germplasm resources, a core collection (containing 34 individuals derived from 10 genetic groups) was first constructed based on phenotypic growth traits and whole-genome resequencing (WGS) data.
