Resumen
Background: Bud dormancy is a crucial stage in perennial trees and allows survival over winter to ensure optimal
flowering and fruit production. Recent work highlighted physiological and molecular events occurring during bud
dormancy in trees. However, they usually examined bud development or bud dormancy in isolation. In this work,
we aimed to further explore the global transcriptional changes happening throughout bud development and
dormancy onset, progression and release.
Results: Using next-generation sequencing and modelling, we conducted an in-depth transcriptomic analysis for all
stages of flower buds in several sweet cherry (Prunus avium L.) cultivars that are characterized for their contrasted
dates of dormancy release. We find that buds in organogenesis, paradormancy, endodormancy and ecodormancy
stages are defined by the expression of genes involved in specific pathways, and these are conserved between
different sweet cherry cultivars. In particular, we found that ...
