ABSTRACT The first phototrophic member of the bacterial phylum Gemmatimonadota, Gemmatimonas phototrophica AP64T, received all its photosynthesis genes via distant horizontal gene transfer from a purple bacterium. Here, we investigated how these acqu

ABSTRACT On circular bacterial chromosomes, the majority of genes are coded on the leading strand. This gene strand bias (GSB) ranges from up to 85% in some Bacillota to a little more than 50% in other phyla. The factors determining the extent of the

The bacterium Gemmatimonas phototrophica AP64 isolated from a freshwater lake in the western Gobi Desert represents the first phototrophic member of the bacterial phylum Gemmatimonadota. This strain was originally cultured on agar plates because it d

Polyploidy in sturgeons makes them highly susceptible to interspecific hybridization, and these interspecific hybrids have been described in nature as well as in captivity. Nevertheless, the fitness-related traits between sturgeon hybrids and pure sp

DNA damage caused by exogenous or endogenous factors is a common challenge for developing fish embryos. DNA damage repair (DDR) pathways help organisms minimize adverse effects of DNA alterations. In terms of DNA repair mechanisms, sturgeons represen

Hatchery-reared sterlet originating from the Danube and Volga river basins that showed population-discriminatory alleles on at least one microsatellite locus were used to produce purebred (within-population) and hybrid crosses to evaluate intraspecif

Gynogenetic progeny of sterlet Acipenser ruthenus were obtained by inseminating eggs with UV-inactivated sperm followed by meiotic restoration of ploidy by heat shock. Gynogenetic origin of progeny was assessed by parentage assignment using 15 micros

The aim of the present study was to estimate and compare the growth and survival traits of the hybrids and purebreds produced by crossing the Siberian sturgeon (Acipenser baerii) (S) and sterlet (Acipenser ruthenus) (St) in order to determine the het
