Double fertilization; Early seed-development; Environmental stresses; Abiotic stresses

My lab studies plant responses to environmental stresses as well as sexual reproduction processes: double fertilization and early seed development. The research is carried out in model organism Arabidopsis thaliana as well as important regional crops such as apple and pear. The studies in my lab are carried out using genetic, molecular-biology, physiology and cell biology approaches.
