P07 – POLPRO: Control of pollen production under changing environment conditions

Abstract
This project explores how environmental factors, such as temperature and light, influence pollen production and male fertility in plants, focusing on Nicotiana species and cytoplasmic male sterility (CMS) systems. While heat stress typically reduces pollen formation, some male-sterile plants surprisingly regain fertility under elevated temperatures. By uncovering the developmental stages and molecular mechanisms behind this phenomenon, the project will help to develop strategies that ensure stable pollen production and hybrid breeding in the face of climate change.
