Serological variability of the Pellia endiviifolia-P. megaspora complex

Abstract

Analysis of antigenic proteins in populations of terrestrial and aquatic forms of P. endiviifolia and populations from Japan revealed the antigenic differentiation of the examined samples into two distinct groups. Pellia megaspora from the eastern part of the USA also exhibits a significant antigenic devergence and bears the most resemblance to the group of populations of the aquatic form of P. endiviifolia from Poland and samples from Japan. The observed serological distances between terrestrial and aquatic forms of P. endiviifolia are of the same rank as differences between remaining species of the genus Pellia. Clarification of the nature of the detected serological differentiation in the Pellia megaspora-P, endiviifoliacomplex will require further studies.
