Little is known about the genome of Anthurium other than chromosome observations, which frequently indicate supernumerary (“B”) chromosomes. New genome size estimates for 34 species and nine cultivars presented here  provide insights into genome organization and evolution in this very large genus.

Molecular genetic diversity and population structure analysis were used to clarify the controversial botanical classification of Stylosanthes guianensis.  In this paper, the accessions were clustered in nine groups, each of which was mainly composed of only one of the four botanical varieties.

Innovative MTOCs organize mitotic spindles in bryophytes, the earliest extant lineages of land. Triple staining of γ-tubulin, microtubules, and nuclei here reveal that three types of MTOCs initiate spindles in bryophytes. Polar organizers in liverworts and plastid MTOCs in hornworts are unique and nuclear envelope MTOCs in mosses appear like those in seed plants. Roy C. [...]
