Modulation of Dormancy and Growth Responses in Reproductive Buds of Temperate Trees.

摘要: During autumn perennial trees cease growth and form structures called buds in order to protect meristems from the unfavourable environmental conditions, including low temperature desiccation. In addition increased tolerance these abiotic stresses, reproductive modulate developmental programmes leading dormancy induction avoid premature resumption, flowering pathways. Stress tolerance, processes are thus physically temporarily restricted a bud, consequently forced interact at regulatory level. We review recent genomic, genetic molecular contributions knowledge of three trees, highlighting role epigenetic modifications, phytohormones, common factors. Finally, we emphasise utility transcriptomic approaches for identification key structural genes involved bud processes, illustrated with our own experience using peach as model.
