Physical wounding and ethylene stimulated embryogenic stem cell proliferation and plantlet regeneration in protocorm-like bodies of Phalaenopsis orchids.
Phalaenopsis orchids have been regenerated by inducing protocorm-like bodies (PLBs) from etiolated leaf sections. However, the physiological and molecular mechanisms of secondary PLB development and subsequent proliferation have not been explored. Bisectionally cutting primary PLBs resulted in more secondary PLBs at 5 weeks, suggesting an embryogenic stem cell property imposed by wounding of pr...
متن کاملProtocorms and Protocorm-Like Bodies Are Molecularly Distinct from Zygotic Embryonic Tissues in Phalaenopsis aphrodite.
The distinct reproductive program of orchids provides a unique evolutionary model with pollination-triggered ovule development and megasporogenesis, a modified embryogenesis program resulting in seeds with immature embryos, and mycorrhiza-induced seed germination. However, the molecular mechanisms that have evolved to establish these unparalleled developmental programs are largely unclear. Here...
متن کاملEffects of organic additives and different carbohydrate sources on proliferation of protocorm- like bodies in Dendrobium
The purpose of this study was to investigate the effect of the addition of different organic additives and sugar types as carbon source on the growth and proliferation of protocorm-like bodies (PLBs) of a very new Dendrobium hybrid known as D. Alya Pink (DAP). PLBs were supplemented with homogenates of banana, tomato, and coconut water at various concentrations. Proliferation rate was recorded ...
متن کاملEffects of culture medium and supplementation on seed germination, protocorm formation and regeneration of some Phalaenopsis hybrids
An efficient protocol is suggested for in vitro culture of five Phalaenopsis hybrids obtained by hand-cross-pollination of three commercial hybrids Calgary, Ankara, and Kendall. Four nutrient media- namely half-strength Murashige and Skoog, Knudson, Phytamax containing activated charcoal, and Mitra– once supplemented (with coconut water, peptone, or both), and once without any supplement were c...
