The main purpose of my PhD thesis project is to analyse gene expression changes occurring in grapevine affected by Flavescence dorée, an epidemic disease caused by phytoplasma (FDp) infection. More in detail, objective of the thesis is to investigate the evolution of recovery mechanisms in plants of Vitis vinifera cv Barbera, subjected to different abiotic stress treatments performed under controlled conditions.

Strigolactones are carotenoid derived phytohormones acting as master regulators of several aspects of plant development and physiology. In particular, they play an important role in plant drought stress resistance by modulating guard cells movements and ABA sensitivity.

Within my PhD I am interested in elucidating the role of strigolactones in stomata after-effect, a drought stress recovery specific process characterized by hysteresis of stomata closure after rewatering.

Grapevine root acts mostly as a sink of carbon during periods of water availability. During periods of drought stress, root changes drastically its metabolism, orchestrating whole plant stress responses. The goal of my PhD project is understand the pattern of carbon allocation to sink organs (root and fruits) during periods of drought stress and post-drought. Studies of C allocation follow pulse-chasing isotopic C strategy and involve ecophysiological and molecular investigation.

The aim of my PhD project is to investigate the molecular and physiological response of crop plants during drought stress and the recovery period using tomato as model. The general aim is to find new markers of drought stress resilience and I am particularly focused in elucidating the role of ORA47, a transcription factor that might repress strigolactone and ABA biosynthetic gene expression under well-watered conditions.
