Induced Androgenic Embryogenesis in Cereals

LECTURES Induced embryogenesis via egg cell activation in cereals

اثر رقم، نوع محیط کشت و ترکیب هورمونی آن بر کشت بساک توت‌فرنگی (.Fragaria × ananassa Duch)

Production of haploid plants is an efficiant method in plant breeding programs, genetics and cytogenetics studies. Effects of cultivar, medium and plant growth regulators were investigated on anther culture of strawberry. This study was carried out using two commercial cultivars of satrawberry (Selva and Paros), three medium (MS, H1 and N6) and different concentrations of IAA and BAP as factori...

Androgenic switch: an example of plant embryogenesis from the male gametophyte perspective.

Embryogenesis in plants is a unique process in the sense that it can be initiated from a wide range of cells other than the zygote. Upon stress, microspores or young pollen grains can be switched from their normal pollen development towards an embryogenic pathway, a process called androgenesis. Androgenesis represents an important tool for research in plant genetics and breeding, since androgen...

Induction of Callus and Somatic Embryogenesis from Cotyledon Explants of Fagonia indica Burm.

To explore the potential for in vitro rapid regeneration of Fagonia indica Burm., cotyledon explants were obtained from 10-day old aseptically germinated seedlings that cultured on MS medium which supplemented with 1.0-5.0 µM 2,4-D. Callus was initiated from cotyledon explant on MS medium supplemented in all concentrations of 2,4-D investigated. 2,4-D was more effective than IAA and NAA for cal...

A Study on Evening-Primrose (Oenothera biennis L.) Callus Regeneration and Somatic Embryogenesis

Evening primrose (Oenothera biennis L.) is a wild flower with high and valuable oil content. High seedshattering, indeterminate inflorescence and heterogeneous germination limit the commercial cultivation ofthis plant. Besides agronomical research, breeding programs can also remedy the above mentioned problems.Since traditional breeding methods take a long time, using techniqu...
