Developmental timing in the female reproductive cycle of Araucaria araucana: seasonality and evolutionary perspectives AbstractBackground and Aims. Shifts in the timing and rate of reproductive development have played a central role in plant evolution, often being shaped by

The study provides the first detailed comparison of female cone development timing in Araucariaceae, highlighting how conserved structures can differ in developmental timing. (8/8)

The committee and the new doctors

February was the month of PhD vivas! This time in Milano, two at the same time, Camilla BANFI and Chiara ASTORI, supervised by Lucia Colombo. In the committee, with Lucio Conti and Barbara Baldan. Great work and a lot to learn (for me at least) #PlantScience #LoveTourGametophytes #PlantReproduction
