The genetic basis of natural variation in the timing of vegetative phase change in Arabidopsis thaliana.

ABSTRACT: The juvenile-to-adult transition in plants is known as vegetative phase change and is marked by changes in the expression of leaf traits in response to a decrease in the level of miR156 and miR157. To determine whether this is the only mechanism of vegetative phase change, we measured the appearance of phase-specific leaf traits in 70 natural accessions of Arabidopsis thaliana. We found that leaf shape was poorly correlated with abaxial trichome production (two adult traits), that variation in these traits was not necessarily correlated with the level of miR156, and that there was little to no correlation between the appearance of adult-specific vegetative traits and flowering time. We identified eight quantitative trait loci controlling phase-specific vegetative traits from a cross betwee
