Presence-absence polymorphisms of single-copy genes in the stony coral Acropora digitifera.

ABSTRACT:

Background

Despite the importance of characterizing genetic variation among coral individuals for understanding phenotypic variation, the correlation between coral genomic diversity and phenotypic expression is still poorly understood.

Results

In this study, we detected a high frequency of genes showing presence-absence polymorphisms (PAPs) for single-copy genes in Acropora digitifera. Among 10,455 single-copy genes, 516 (5%) exhibited PAPs, including 32 transposable element (TE)-related genes. Five hundred sixteen genes exhibited a homozygous absence in one (102) or more than one (414) individuals (n = 33), indicating that most of the absent alleles were not rare variants. Among genes showing PAPs (PAP genes), roughly half were expressed in adults and/or larvae, and the PAP
