Environmental plasticity of asexual endosperm formation in Arabidopsis (A02)

• Subject Area: Plant Cell and Developmental Biology
• Term: since 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 512328399

A2 (Figueiredo) will investigate the plasticity of asexual endosperm development to ambient temperature. In many apomictic species that can form asexual seeds, the ratio of sexual versus asexual reproduction depends on the environment. In Arabidopsis, asexual seed development is seen in some mutants and can be induced in wild type by hormone treatment. The project will determine the reaction norms of hormone-induced asexual seed development to temperature across Arabidopsis accessions and study the underlying genetic basis for variation in plasticity by quantitative genetics, complemented by a candidate approach to study the intergration of temperature response across different seed tissues.
