DNA fingerprinting of non-human populations is beginning to fulfill its early promise, and in the past year there has been a flush of papers on mammalian breeding systems. However, many people, particularly field workers, believe that progress in this area has been slow. Attention is now focused on two amenable alternatives: microsatellite polymorphisms and randomly amplified polymorphic DNA. Of these, it is probable that microsatellites hold the key to rapid, efficient and highly informative screening of the genetic variability that exists within natural populations.

The Psu protein of phage satellite P4 inhibits transcription termination factor ρ by forced hyper-oligomerization.

Many bacteriophages modulate host transcription to favor expression of their own genomes. Phage satellite P4 polarity suppression protein, Psu, a building block of the viral capsid, inhibits hexameric transcription termination factor, ρ, by presently unknown mechanisms. Our cryogenic electron microscopy structures of ρ-Psu complexes show that Psu dimers clamp two inactive, open ρ rings and promote their expansion to higher-oligomeric states.

Recent advancements in viral metagenomics and single-virus genomics have improved our ability to obtain the draft genomes of environmental viruses. However, these methods can introduce virus sequence contaminations into viral genomes when short, fragmented partial sequences are present in the assembled contigs. These contaminations can lead to incorrect analyses; however, practical detection tools are lacking.

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.

PPTC7 is a mitochondrial phosphatase that is essential for mitochondrial biogenesis, metabolism, protein content maintenance and transport. While the mitochondrial roles of PPTC7 are well-characterized, its roles outside the mitochondria are unclear. Here we identified a non-mitochondrial role for PPTC7 in regulating epidermal growth factor receptor (EGFR) trafficking.
