the late sexual maturity in sturgeon and the absence of morphological differences between males and females makes sex discrimination difficult. identification of sex at an early life stage is of high interest in caviar production because it allows efficient selection of females. in this study, the genome of 10 mature male and 10 mature female specimens of persian sturgeon (acipenser persicus...

alzheimer’s disease (ad) is the most common form of dementia in the elderly in which interplay between genes and the environment is supposed to be involved. mitochondrial dna (mtdna) has the only non-coding regions at the displacement loop (d-loop) region that contains two hypervariable segments (hvs-i and hvs-ii) with high polymorphism. mtdna has already been fully sequenced and many subsequen...

Halomonas zhanjiangensis Chen et al. 2009 is a member of the genus Halomonas, family Halomonadaceae, class Gammaproteobacteria. Representatives of the genus Halomonas are a group of halophilic bacteria often isolated from salty environments. The type strain H. zhanjiangensis JSM 078169(T) was isolated from a sea urchin (Hemicentrotus pulcherrimus) collected from the South China Sea. The genome ...

micrornas (mirnas) are short rna molecules which bind to target mrnas, resulting in translational repression and gene silencing and are found in all eukaryotic cells. approximately 2200 mirna genes have been reported to exist in the mammalian genome, from which over 1000 belong to the human genome. many major cellular functions such as development, differentiation, growth, and metabolism are kn...

The causal agent of root and butt rot of conifer trees, Heterobasidion annosum, is widespread in boreal forests and economically responsible for annual loss of approximately 50 million euros to forest industries in Finland alone and much more at European level. In order to further understand the pathobiology of this fungus at the genome level, a Finnish isolate of H. annosum sensu stricto (isol...

Mesotrione is among the most recently marketed herbicides belonging to triketone family and applied on maize crops. A Bacillus megaterium Mes11 strain isolated from an agricultural soil was able completely transform 1 mM of mesotrione, alone or in a mixture with nicosulfuron and/or S-metolachlor herbicides, 5 h. Its complete genome contains one circular chromosome (5,191,612 bp) nine plasmids (...

The ability of the Sendai virus major nucleocapsid protein, NP, to support the in vitro synthesis and encapsidation of viral genome RNA during Sendai virus RNA replication was studied. NP protein was purified from viral nucleocapsids isolated from Sendai virus-infected BHK cells and shown to be a soluble monomer under the reaction conditions used for RNA synthesis. The purified NP protein alone...
