Identification of factors that modulate Proliferative Arrest under the influence of seeds

In monocarpic plants, after the production of a certain number of fruits/seeds, the activity of the Shoot Apical Meristem (SAM) and of the meristems of the secondary axes stop in a coordinated way, leading to the cessation of flower production. This phenomenon has been called Proliferative Arrest (PA). It can be assumed as a general phenomenon in monocarpic plants, as it has been described in different species of this economically important group of plants. Studies in the model species Arabidopsis thaliana and Pisum sativum have allowed the identification of factors that affect PA timing. One of them is the production of fruits and seeds. With this RNA-seq, we have identified factors that contribute to the modulation of PA in a seed-dependent manner in Pisum sativum. To better understand the influence of seeds in modulating Proliferative Arrest, samples of Shoot Apical Meristem were collected at four different stages of plant development (with/withouth seeds; active/arrested meristems)
