Genes involved in floral meristem in tomato exhibit drastically reduced genetic diversity and signature of selection.

ABSTRACT:

Background

Domestication and selection of crops have notably reshaped fruit morphology. With its large phenotypic diversity, tomato (Solanum lycopersicum) illustrates this evolutive trend. Genes involved in flower meristem development are known to regulate also fruit morphology. To decipher the genetic variation underlying tomato fruit morphology, we assessed the nucleotide diversity and selection footprints of candidate genes involved in flower and fruit development and performed genome-wide association studies.

Results

Thirty candidate genes were selected according to their similarity with genes involved in meristem development or their known causal function in Arabidopsis thaliana. In tomato, these genes and flanking regions were sequenced in a core collection of 96 acces
