Presence-Absence Polymorphisms of Highly Expressed FP Sequences Contribute to Fluorescent Polymorphisms in Acropora digitifera.

ABSTRACT: Despite many hypotheses regarding the roles of fluorescent proteins (FPs), their biological roles and the genetic basis of FP-mediated color polymorphisms in Acropora remain unclear. In this study, we determined the genetic mechanism underlying fluorescent polymorphisms in A. digitifera. Using a high-throughput sequencing approach, we found that FP gene sequences in FP multigene family exhibit presence-absence polymorphism among individuals. A few particular sequences in short-to-middle wavelength emission and middle-to-long wavelength emission clades were highly expressed in adults, and different sequences were highly expressed in larvae. These highly expressed sequences were absent in the genomes of individuals with low total FP gene expression. In adults, presence-absence differences of
