Research progress on molecular regulation mechanisms in bulbous plants at dormancy

doi:10.11686/cyxb20130635

Abstract

Abstract: The main factor of dormancy induction in bulbs is the repression of DNA activation. A series of cell genes and proteins are activated during dormancy breaking, Using Arabidopsis, poplar, and potato as model plants it has been found that the systems of endogenous hormone balance and their levels regulate the processes of dormancy, and that carbohydrates are continually transformed in the bulbs. The degradation of starch provides materials and energy. Dormancy characteristics can be delayed or brought forward using genetic engineering. Recent research progress on inducing dormancy and on dormancy breaking in bulbous plants are summarized in this review and the prospects for further research on bulb dormancy are discussed.
