[SCAN] The development of the non-endospermic seed of the legume Phaseolus vulgaris L. (common bean)

Title: The development of the non-endospermic seed of the legume Phaseolus vulgaris L. (common bean)

Abstract: The common bean is one of the most important grain legumes worldwide, especially in Subarian and South-American developing countries, due to its high content of protein, fiber, essential vitamins and minerals. In addition, the green immature pods are also consumed as a vegetable and are an important fresh product with increasing production worldwide.

Despite the agronomic and economic importance of this legume, little is known about how common bean seeds develop. Seed development is a complex process that begins with double fertilization and usually comprises three phases in orthodox seeds: embryogenesis, filling and desiccation.

We addressed the major molecular and metabolic mechanisms underlying common bean seed development, focusing on the transition from embryogenesis to filling because of its relevance to seed yield and quality. We also investigated the effect of heat stress on this important stage of seed development. Our results allow us to better understand the genetic, molecular and physiological control of non-endosperm seed development, with implications for future strategies to optimize legume seed quality and resilience to environmental stresses.

SCANs are weekly seminars that happen every Wednesday at noon by in-house researchers and invited speakers at ITQB NOVA.
