F. Cardinale is Associate Professor in Plant Physiology at the University of Turin, Italy. Her research has generally been within a group of thematic areas covering molecular plant physiology and pathology, biotic and abiotic stress perception and signal transduction, phytohormones. Her current studies focus on the phytohormones strigolactones both in Arabidopsis thaliana and tomato (Solanum lycopersicum L.) with emphasis on cell type/organ specificity in biosynthesis, perception and effects; role in long-range stress signalling and in stomata closure under drought; interactions with abscisic acid and micro RNAs; effects in developmental phase transition.

Talk title and synopsis
A tale of plant hormones: how strigolactones cross-talk with ABA to set drought responses in tomato
Strigolactones are carotenoid-derived metabolites with a multitude of functions, both in the plant and in the biotic surrounding environment. They have a prominent role as hormones, influencing whole-plant morphology and development also in response to environmental stress. Understanding their biology may help to improve plant yield and resilience in stressful environments. We are trying to unravel what the local and systemic changes of strigolactone levels – observed in different organs of plants undergoing osmotic stress – mean for overall hormonal balance, physiology and water relations in tomato (Solanum lycopersicum L.). Specifically, we aim to elucidate the molecular underpinnings of strigolactone effects in stress resilience, focusing on the cross-talk with ABA and microRNAs, and of the coordinated synthesis of strigolactones and ABA in leaves.
