Improving Seed Vigour in Brassicaceae (EoI-TSP2-05)

Application deadline:

Posdoctoral position in Plant Developmental Biology: we are looking for a highly qualified and motivated postdoctoral researcher in the area of Plant Science to join our group(…).The researcher to be hired will be involved in the Severo Ochoa TSP project: Improving Seed Vigour in Brassicaceae. Seed vigour is a complex trait shaping crop field emergence and comprisesseed dormancy, germination and seed ling establishment. Genetic and environmental conditions during seed production and storage have a profound effect on seed vigour traits. Less attention has been given to elucidation of the genetic control of seed germination and seed ling vigour compared to other traits. Global warming associated to climate change has become a serious threat world wide, and high temperature is a major environmental factor limiting crop productivity. Arabidopsis is a close relative of Brassica crops and the knowledge gained from this model plant provides valuable guidance to translational biology approaches. Brassica species, particularly canola varieties, are cultivated worldwide for edible oil, animal feed, and biodiesel, and suffer dramatic yield loss upon stress. Genetic and phenotypic analysis of B. napus accessions, indicate that vigour can be substantially improved. Our research is focused on integrative approaches to deepen our understanding of how ambient temperature influence three main stages of seed vigour– seed production, germination and early seedling growth–in Brassicanapus. We will use rapeseed accessions to analyze the effect of temperature on seed vigour traits and study the epigenetic and molecular mechanisms under lying those responses. Finally, usingCRISP-Cas9technology, the activity of promising genes will be modified in B.napus to improve seed vigour of this important crop.
