Karyological and endosymbiotic notes on two Choricystis species (Trebouxiophyceae, Chlorophyta)

Abstract Two species of the genus Choricystis (Choricystis minor and Choricystis chodatii) have been chromosomally surveyed. In addition, their ability to form symbiotic associations with the ciliate Paramecium bursaria was also investigated. Choricystis minor (clone #8931/1 from strain #8931) was i...

Description
Summary:Abstract Two species of the genus Choricystis (Choricystis minor and Choricystis chodatii) have been chromosomally surveyed. In addition, their ability to form symbiotic associations with the ciliate Paramecium bursaria was also investigated. Choricystis minor (clone #8931/1 from strain #8931) was isolated from a moss sample collected on Livingston Island, Maritime Antarctica. Choricystis chodatii (clone #3090/1) was derived from strain #3090 Chodat-type culture (loc. Switzerland, lake Geneva). The karyotypes of both species showed a haploid number of five chromosomes and shared some similarity in the chromosome lengths. The absolute chromosome lengths ranged from 1.25 µm to 2.95 µm. Studied species possess equal abilities for endosymbiotic associations with Paramecium bursaria. Descriptions of the species and a short discussion on their taxonomical status are given.
