Ambient temperature and genotype differentially affect developmental and phenotypic plasticity in Arabidopsis thaliana.

ABSTRACT:

Background

Global increase in ambient temperatures constitute a significant challenge to wild and cultivated plant species. Forward genetic analyses of individual temperature-responsive traits have resulted in the identification of several signaling and response components. However, a comprehensive knowledge about temperature sensitivity of different developmental stages and the contribution of natural variation is still scarce and fragmented at best.

Results

Here, we systematically analyze thermomorphogenesis throughout a complete life cycle in ten natural Arabidopsis thaliana accessions grown under long day conditions in four different temperatures ranging from 16 to 28 °C. We used Q₁₀, GxE, phenotypic divergence and correlation analyses to assess temperature se
