Plant seeds made Russian biologists reconsider their evolution
The family of Molluginaceae, which is related to carnation, includes almost a dozen genera, and representatives of the genera are found on all continents except Antarctica, and the very fact tells of the impressive age of this group. However, the taxonomy of Molluginaceae remains a knotty and not fully understood problem. Connections of genera within the group are established only with the use of genetic data and are not quite reliable.
Alexander Sukhorukov, a leading researcher at the Department of Morphology and Systematics of Higher Plants of Moscow State University, and his colleagues analysed the seeds and fruits of a total of 76 species of Molluginaceae, representing all 11 genera of the family.
This helped trace the evolutionary interrelationship between individual clades, including several genera of the family. The new work is likely to lead to a revision of the classification of the family.
