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 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...
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 کاملEffect of Banana Extract on Growth and Development of Protocorm Like Bodies in Dendrobium sp. orchid
An experiment was carried out in Plant Tissue Culture Laboratory, Department of Crop Botany, Bangladesh Agricultural University, Mymensingh to investigate the effect of banana extract on micropropagation of Dendrobium sp. var. Sonia orchid through PLBs. The experiment was conducted during July 2012 to October 2013. Half-Murashige and Skoog (1/2MS) medium were used as basal medium and the medium...
