Abstract:

The seed containing an embryo, a miniature of new plant, structurally and physiologically equipped to sustain the growing seedling until it establish as new plant. Some traits are acquired during evolution for capacity to survive under unfavourable condition. One of such trait is ‘dormancy’, an intrinsic/extrinsic block to germination. The ABA and GA are involved in induction and release of dormancy and it also showed the involvement and complex interaction with other plant hormones such as ethylene, brassinosteriods and reactive oxygen species. The use of transcriptomic and proteomic analysis refined the variation and similarities of the pathways affected by dormancy and germination. It provides a basis for studying the role of individual genes in these pathways. Advances in molecular technology, especially next-generation sequencing, will make it possible to study non model species in depth at the molecular level. Genetic and molecular mechanisms like silencing and over expression help us to induce and release of seed dormancy in many agricultural crop species which enables to farmers to take up sowing at any time.


Keywords: Seed dormancy, Seed germination, ABA and GA.
