Arabidopsis abi3 and fus3 mutants are defective in late embryo development and their embryos show precocious growth. To understand the function and role of ABI3 and FUS3, we analyzed expression patterns of genes which were normally activated during late embryo development and germination in these mutants. Using the differential display method, both upregulated and downregulated genes were obser...

Introduction: In vitro maturation and development of immature oocytes, as an artificial reproduction technique, is useful especially in women who are affected by cancer and polycystic ovary syndrome. Despite using many types of in vitro media, an appropriate environment has not been reported yet. Present study was designed to assess the effect of heated human follicular fluid (hHFF), which is s...

Background and purpose: The purpose of this study was to evaluate the effect of mouse embryonic fibroblast cells conditioned medium on resumption of meiosis, in vitro maturation of immature mouse oocytes, fertilization and derived embryos development. Material and Methods: Immature oocytes denuded at the germinal vesicle (GV) stage were obtained from female NMRI mice 46-48 hrs after injecti...

Background: Since the sheep ‘Dolly’ was successfully cloned by somatic cell nuclear transfer (SCNT), the inefficiency of SCNT cloning and abnormality of cloned animals have been a focus of considerable controversy. Oocyte quality has been shown to contribute to poor somatic cloning and cell reprogramming efficiency with many factors affecting oocyte quality and developmental potential. It has b...

The purpose of the research study is to select the best rice explant and variety for Agrobacterium mediated genetic transformation studies. In vitro callus induction and regeneration frequency of two explants i.e. immature embryo and mature grains of 9 rice varieties (Oryza sativa L.) was investigated by culturing explants source on N6 media supplemented with 2, 4-D at 2mg/l for callus inductio...

Gamete cryopreservation combined with in vitro embryo production (IVP) and cryopreservation of resultant embryos are important technologies for gene banking in domestic animals. Especially, cryopreservation of embryos and oocytes offers the possibility for the preservation of female genetic lines. Although several vitrification protocols have been developed for the cryopreservation of embryos a...

Paeonia ostii ‘Feng Dan’ is an economically important, multipurpose woody plant in terms of its medical, ornamental, and oil values; however, there a noticeable contradiction between the increasing demands lack excellent germplasm resources because traditional breeding propagation approaches. In vitro embryo culture attractive option for this issue. This study presents protocol immature P. Dan’...
