ACE2 and TMPRSS2 polymorphisms and the development of COVID-19: a review of the literature
Published on: 28th April, 2022
SARS-CoV-2 is a virus that has a positive-sense, single-stranded RNA genome that encodes 4 structural proteins, the main one being the S protein (Spike) responsible for mediating with ACE2 and TMPRSS2 for entry into the host cell. The study of single nucleotide polymorphisms (SNPs) of ACE2 and TMPRSS2 can elucidate their possible intervention in the action of the protein, its activity, and the gene expression of encoding these enzymes, which may increase susceptibility to viral infection. From this, literature searches were carried out until December 2021, listing 11,820 publications for literary analysis on the described genetic variations of these protein structures, as well as their relation and influence on the pathology. It was possible to conclude that there is a great influence exerted by genetic variability in ACE2 and TMPRSS2 increasing the ability of the virus to bind to the host cell and the development of COVID-19 with complications.
Genetic variability, divergence, and path coefficient analysis of yield and yield related traits of Durum wheat (Triticum turgidum l. var. Durum) genotypes at Jamma district, south wollo zone, amhara region, Ethiopia

Durum wheat (Triticum turgidum L. var. durum) is a member of the Poaceae family and tetraploid (genomes of AABB) with 28 chromosomes (2n=4x=28). Narrow genetic variability was a problem to develop genotypes with better adaptation to different agro-ecologies. Therefore, the objective of this study was to investigate the genetic variability, divergence, and path coefficient analysis of durum wheat genotypes by using morphological traits and identifying essential yield-related traits of durum wheat, and to identify promising candidate genotypes to be used in future durum wheat breeding program. The study was carried out on 81 genotypes and the experiment was laid out in a triple lattice design with an arrangement of 9 x 9 x 3 treatment, which made 243 experimental units. Results obtained on genetic variability, path coefficient, and genetic divergent analysis among yield-related traits are presented here under the present study. Generally, the present study revealed the existence of significant genetic variability among the tested genotypes for different traits helpful for direct and indirect selection.This study recommended that the potential durum wheat genotypes 214552, 208150, 238516, 5645, Mekuye, 236984, 7960, 7152, 231599, and 208242 could be used for durum wheat breeding programs for yield and yield component traits improvement under similar agro-ecologies.
Genetic variability in the susceptibility of immature peach fruit to Monilinia laxa is associated with surface conductance but not stomatal density
Published on: 25th August, 2022
OCLC Number/Unique Identifier: 9599097875
Monilinia laxa is a fungus that causes brown rot in stone fruit. Immature green fruits in the first stage of fruit development (stage I) are generally susceptible. To investigate the relationship between the physical characteristics of immature fruit and susceptibility to M. laxa, we characterized the progeny, derived from a clone of wild peach (Prunus davidiana) crossed with two commercial nectarines (Prunus persica) varieties, through laboratory infection, transpiration monitoring and stomata counting. Two types of fruit infections were observed - ‘classic’ brown rot and ‘clear spot’ symptoms - which have not previously been described in the literature. The number and density of stomata did not explain the observed variability of infection in the progeny. However, surface conductance was positively correlated with infection level. This study provides experimental evidence partially linking physical fruit characteristics to brown rot infection at the immature fruit stage. The role of delayed cuticle deposition in susceptibility to brown rot of immature fruit is discussed.
A look at polyploidy and plant breeding
Published on: 28th November, 2022
Polyploidization is a process that generates genetic variability and therefore one of the engines of biological evolution. Since polyploidization produces important changes in the phenotype, mainly an increase in the size of the organs (i.e.: flowers and fruits), it is also a very important and powerful tool for plant improvement. Despite its intense use in breeding programs for various species, very little is known so far about the nature of this phenomenon. This work presents a brief review of the results obtained by the use of this tool in plant breeding and also raises some reflections on its mechanism of action.
