Comprehensive characterization and phylogenetic analysis of the complete plastomes of two ant-orchids, Caularthron bicornutum and Myrmecophila thomsoniana.

ABSTRACT:

Background

Myrmecophytes, characterized by specialized structures like hollow stems that facilitate mutualistic relationships with ants, serve as an important system for studying ant-plant interactions and the adaptation mechanisms. Caularthron and Myrmecophila are exemplary myrmecophytes within Orchidaceae. Previous studies suggested a genetic relationship between these two genera, placing them within Laeliinae (Epidendreae), yet the precise phylogenetic positioning remained uncertain. The absence of available plastome resources has hindered investigations into plastome evolution and phylogeny.

Results

In this study, we sequenced and assembled the complete plastomes of Caularthron bicornutum and Myrmecophila thomsoniana to elucidate their plastome characteristics and phylog
