In the Mexican axolotl (Ambystoma mexicanum), sex is determined by a single Mendelian factor, yet its sex chromosomes do not exhibit morphological differentiation typical of many vertebrate taxa that possess a single sex-determining locus. As sex chromosomes are theorized to differentiate rapidly, spec...
The formation of meiotic DSBs is commonly resolved via crossovers (COs) or other recombination outcomes, called non-COs3. COs can be divided into two classes4,5. In plants, class I COs are the most prevalent and are sensitive to interference—they do not occur near each other along a ...
May you enjoy serious discussions re the size of a movie monster’s head with someone you love; May you be the good people still willing to fight the good fights; May you convert to pacifism anyone foolish enough to declare that people are declaring a war on any holiday; ...
Joanna Kowal and his team showed several classical exosomes by proteomic analysis, and proteins such as major histocompatibility complexes (MHC), flotillin, and 70 kD heat shock protein were found in almost all EVs. They finally identified proteins that are specifically enriched in small EVs and ...
Among the major compounds of chicory root, inulin has been the subject of multiple studies concerning its prebiotic effect [2,3], but less is known about the specific mechanisms of other molecules that enter the composition of roots. The hydrolysis products of inulin, fructose and oligofructose,...
Meiosis is a highly conserved specialized cell division process that generates haploid gametes. Many of its events are associated with dynamically regulated chromosomal structures and chromatin remodeling, which are mainly modulated by histone modificati
Meiosis of interspecific hybrids and cytological maps of three complete genomes of lilies (L, A, O) based on recombination sites in BC progenies of two interspecific hybrids[8] were studied. On the other hand, genetic mapping of lily has not yet been well studied. The currently available ...
