Somatic embryos and plants were produced from mature and immature embryo derived callus of wheat. Immature embryo showed a better capacity for somatic embryogenesis and plant regeneration. Presence of 2, 4-D was shown to be essential for induction and maintenance of somatic embryogenesis. Organic nitrogenous additives (L-proline, L-asparagine and casein hydrolysate) marked an effect on somatic ...

Wheat (Triticum aestivum L.) is one of the most successful domesticated plant species in the world. The majority of wheat carries mutations in the Puroindoline genes that result in a hard kernel phenotype. An evolutionary explanation, or selective advantage, for the spread and persistence of these hard kernel mutations has yet to be established. Here, we demonstrate that the house mouse (Mus mu...
