THE ACADEMICIAN N.I. VAVILOV AND INTRODUCTION OF RICE IN RUSSIA

Зерновое хозяйство России, 2018
The article considers the role of N.I. Vavilov in creating the theory of introduction of plants. N.I. Vavilov was the first who showed the possibility and practicability of expanding rice from the southern parts of the country to the northern ones ...

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Yeast Gcn2 retains activity following humanization of its auto‐phosphorylation region

FEBS Open Bio, EarlyView.
Using Saccharomyces cerevisiae as a model to study Gcn2 activation and regulation is limited by the lack of antibodies detecting phosphorylated Gcn2. To overcome this, we engineered Gcn2‐HsC, a yeast Gcn2 variant recognizable by commercial anti‐human phospho‐GCN2 antibodies.

Analysis of genotype resistance and HIV‐1 transmission risk in HIV‐1‐infected men who have sex with men in Guiyang, China

Immunity, Inflammation and Disease
Background As the social economy has developed and population mobility has increased, differences in the Human immunodeficiency virus type 1 (HIV‐1) genotype distribution among men who have sex with men (MSM) have become apparent in the provinces and ...

ATZ‐1 promotes DNA replication efficiency to maintain normal meiotic function

FEBS Open Bio, EarlyView.
Absence of ATZ‐1 interferes with meiotic DNA replication and cell cycle function via CHK‐1. This causes downstream defects associated with DNA damage and genomic integrity. Taken together, this study suggests that ATZ‐1 influences DNA replication efficiency and cell cycle function to maintain normal meiotic function.

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants

FEBS Open Bio, EarlyView.
Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...

Parametric and Non-Parametric Measures to Identify Stable and Adaptable Cotton (Gossypium Hirsutum L.) Genotypes

Journal of Natural Fibers
The study, comprised seventeen genotypes, was conducted during 2016 to 2019 growing seasons. The design was Randomized Complete Block Design (RCBD) with three replications to identify adaptable cotton genotypes.

Thalassemia: genotypes and phenotypes

Annals of Hematology, 1991
The large degree of phenotypic heterogeneity of thalassemia can now be related to the underlying genomic defects. This information has accumulated rapidly over the last years through the recent advances in molecular technology. The list of main types of thalassemia (alpha or beta) that can be differentiated includes several gene deletions (complete or ...

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

FEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Molecular detection of piroplasms, Anaplasma, and Ehrlichia species in Kazakhstan

Frontiers in Veterinary Science
Tick-borne pathogens (TBPs) are a global public health issue. However, there have been few reports on the prevalence of piroplasms, Anaplasma, and Ehrlichia in Kazakhstan.
