Dynamic transcriptomic features accompanying the onset of first flowering in roses.

ABSTRACT:

Background

Onset time of the first flowering is pivotal for the reproductive success of perennial polycarpic plants especially in woody species, like roses. Despite the key innovation of continuous flowering in some roses, little is known about the molecular features underlying the onset of their first flowering due, in large part, to the difficulties in the promotion and synchronization of seed germination.

Results

In this study, we optimized a germination procedure to explore the dynamic transcriptomic features along seedling establishment through the first flowering in a rose line, Rosa 'Yann Arthus-Bertrand'. Low temperature treatments at 5 °C or 10 °C for three or four months significantly enhance germination rates up to 60%. We then generated leaf transcriptomes for fi
