Plant dormancy research: from environmental control to molecular regulatory networks.

Yamane H,Wada M,Honda C et al. (2019) Overexpression of Prunus DAM6 inhibits growth, represses bud break competency of dormant buds and delays bud outgrowth in apple plants. Potential bud dormancy regulators DAM/SVP2/SVL Our understanding of molecular regulators of bud dormancyactivity cycles has increased substantially in the last decade. In the Rosaceae, the flowering period between the formation of floral meristem (i.e., structural conversion of the vegetative shoot apical meristem in terminal, lateral and adventitious buds to the floral meristem with ensuing floral organ primordia formation) and anthesis spans several months over autumn and winter. This leads to the question of whether Rosaceae floral buds establish dormancy during tree dormancy phase, or if the term dormancy should not be used in the case of winter floral buds of Rosaceae family members.
