Abstract Leucojum aestivum is a valuable and endangered plant species with bulb scales best suited as explants in micropropagation. In the current study, its micropropagation was investigated by using two different various concentrations combinations of growth regulators (PGRs). Bulbs were first disinfected benomyl® for 5 hours. After meeting chilling requirements, two-scale four-scale provided...

The midto long-term preservation of papaya (Carica papaya L.) would allow for the safeguarding of important germplasm. In this study, soft friable callus (SFC) and hard callus (HC) were induced from the first two true leaves of 10-day-old seedlings containing a midrib derived from the germinated seed of two cultivars (‘Rainbow’ and ‘Sunrise Solo’). Following germination on a Murashige and Skoog...

Arabidopsis LEAFY COTYLEDON (LEC) genes, AtLEC1 and AtLEC2, are important embryonic regulators that play key roles in morphogenesis and maturation phases during embryo development. Ectopic expression of AtLEC1 and AtLEC2 in tobacco caused abnormality in transgenic seedling. When transgenic seeds germinated on medium containing 30 µM DEX, LEC1 transgenic seedlings were ivory and fleshy, with une...

the jatropha curcas l., a plant belongs to euphorbiaceae family, which has great economic and medicinally value. there is high amount of oil in seeds of this plant. because of low germination ability of seed, propagation of jatropha curcas via seed is not usual. the purpose of this work is optimizing of jatropha curcas tissue culture for optimization of callus formation and propagation through ...

A study of callus induction of Tecomella undulata was conducted using a various concentrations of PGRs namely cytokinins such as BAP and KIN and auxins such as 2, 4-D, NAA and IAA. Internodal explants were aseptically cultured on MS medium supplemented with different concentrations (1.03.0 mg/l) of BAP, KIN, 2, 4-D, IAA and NAA. After two weeks callus was formed at the cut surface of the explan...
