Short communication. Phylogeny and genetic diversity within Iberian populations of Ornithopus L. and Biserrula L. estimated using ITS DNA sequences T
Abstract
Genetic diversity within Iberian populations of Ornithopus pinnatus, O. compressus, O. sativus and Biserrula pelecinus were assessed using ITS1 and ITS2 DNA sequences from sixty four specimens, and a phylogeny between Ornithopus species was estimated. Generally within-species variation was low, particularly within Ornithopus. The Mediterranean species of Ornithopus form a sister clade relative to the South American O. micranthopus. The sometimes considered a full species, O. sativus isthmocarpus, was not distinct from O. sativus. Between some species there is limited genetic divergence using these markers, although the situation of O. perpusillus requires additional specimens to be examined before firm conclusions can be drawn.
