Horizontal transfer (HT) is an event in which the genetic material is transferred from one species to another, even if distantly related, and it has been demonstrated as a possible essential part of the lifecycle of transposable elements (TEs). However, previous studies on the non-LTR R2 retrotransposon, a metazoan-wide distributed element, indicated its vertical transmission since the Radiata-...

The invasion success of gibel carp (Carassius gibelio) depends on demographic and competitive traits. major biological trait responsible for the invasiveness C. gibelio is mode reproduction. Apart from sexual reproduction, which typical in fish, a unique cyprinid species able to reproduce through asexual gynogenesis, also known as sperm-dependent parthenogenesis, observed all-female populations...

This study’s objective was to explore some of the annual Prussian carp’s (Carassius gibelio) biological characteristics (sex ratio, length–weight and gonado somatic index - GSI) in Kopački Rit Nature Park Croatia. The carp is an invasive fish species originated from Asia, which became widely distributed throughout Europe believed be responsible for a decline number indigenous fish, invertebrate...

The purpose of this work was to study the effects of ultraviolet (UV) irradiation on denucleation of eggs and investigate the heat-shock conditions for diploidization for induction of androgenesis in muskellunge, Esox masquinongy. Several egg incubation media, including saline, Ringer's solution, and Ringer's solution supplemented with bovine serum albumin (BSA), were found suitable to maintain...

Abstract Sugar beet ( Beta vulgaris L.) is referred to as a strategic species due its exceptional economic and functional importance. cultivated in order provide material for sugar production it the world’s second source after cane. However, this species, regeneration of haploid shoots difficult comparison other cultures or isolated microspores. Haploid plants can be derived from vitro culture ...
