Summary

A1 (Kaufmann) will study plasticity of leaves and flowers to temperature and to light quality in Arabidopsis thaliana. While leaves show a high plasticity to a range of environmental cues, floral organs generally are much less plastic, and their growth is highly integrated. The project will characterize the phenotypic responses of leaf and floral traits to variation in temperature and light quality and query the degree of phenotypic integration between vegetative and reproductive organs. Quantitative genetics complemented by organ-specific and single-cell transcriptomics will identify loci affecting plasticity and the level of phenotypic integration.
