Aspergillus fumigatus fingerprints generated by random amplification of polymorphic DNA (RAPD), restriction fragment length polymorphism (RFLP) upon hybridization with repeated DNA sequences, and PCR detection of microsatellite length polymorphism (MLP) were compared among 67 isolates. In contrast to RAPD, RFLP and MLP gave discriminating and significantly concordant genotyping results.

Y-chromosomal short tandem repeats (Y-STRs) at rapidly mutating (RM) loci have been suggested as tools for differentiating paternally related males. RMplex is a recently developed system that incorporates 26 RM loci and four fast-mutating (FM) loci, targeting 44 male-specific loci. Here, we evaluated the RMplex by estimating Y-STR mutation rates and the overall differentiation rates for 542 Korean father-son pairs, as well as the genetic population values for 409 unrelated males.

Segmental duplications (SDs) contribute significantly to human disease, evolution and diversity but have been difficult to resolve at the sequence level. We present a population genetics survey of SDs by analyzing 170 human genome assemblies (from 85 samples representing 38 Africans and 47 non-Africans) in which the majority of autosomal SDs are fully resolved using long-read sequence assembly. Excluding the acrocentric short arms and sex chromosomes, we identify 173.

Enhancing salt tolerance genetically through defining the genetic and physiological mechanisms intergenerational and transgenerational stress memory that contributes to sustainable agriculture by reducing the reliance on external inputs such as irrigation and improving the adaptability of barley to changing climate conditions. Salinity stress poses a substantial challenge to barley production worldwide, adversely affecting crop yield, quality, and agricultural sustainability. To address this, the present study utilized a genome-wide association san (GWAS) to identify genetic associations underlying intergenerational and transgenerational stress memory in response to salinity in a diverse panel of 138 barley accessions.

The presence of Azotobacter bacteria in the soil plays an important role in increasing its fertility and enhancing plant health. Azotobacter diversity depends on several environmental factors, particularly soil texture, pH, and nutrient content. The current study investigated the diversity of Azotobacter in various soil samples collected from 10 different governorates along the river Nile valley and its delta, Northern Mediterranean shore, Sinai, and Upper Egypt regions.
