Banana micropropagation for obtaining free-virus plants frequently provokes somaclonal variation that could increase useful genetic variability in this asexually propagated crop. Both exploring the cycle of vitro culture which occurs and amount generated polymorphism, are necessary. In work, preliminary results during early cycles banana reported. Four randomly selected regenerated from fifth t...

The clonal propagation of T. cacao by somatic embryogenesis (SE) is a promising approach to multiply elite genotypes. Assessing fidelity in plants regenerated from embryos the first step toward ensuring genetic uniformity mass production planting material. This study assessed stability plantlets propagated SE and conventional grafting for genotypes CCN51 TSH565 using 13 SSR. leaves vitro (IVL) ...

The natural lignan podophyllotoxin, a dimerized product of two phenylpropanoid moieties which occurs in a few plant species, is a pharmacologically important compound for its anticancer activities. Optimization of the in vitro cultures might lead to a renewable source of lignans for medicinal uses. In order to maximize efficiency of podophyllotoxin accumulation via in vitro cultures, the effect...

background to current knowledge, different oocyte's recovery method and various seasons have profound impact on in vitro embryo production (ivep). objectives the aim of this study was to define an efficient recovery method for oocytes harvesting from slaughterhouse material in different seasons, and their effects on ivep yield. materials and methods ovaries from slaughtered ewes in breeding sea...

Every plant propagated by cutting is a clone of the original. Thus cloning of plants has been done since antiquity. Cloning of animals is something new. This paper reviews recent experiments with cloning of animals.

In order to optimize the micropropagation of Qare-Qat (Vaccinium arctostaphylus J.J.Sm), samples were collected from two regions of Iran (Asalem and Kelardasht). Anderson (AN) media containing different concentrations of zeatin (0, 0.5, 1, 2 and 4 mg L-1) and different levels of pH (4.5, 5 and 5.5) were compared. The in vitro shoots were transferred on AN media supplemented with zeatin (1 and 2...
