Chromosome Evolution In Cyperales, Eric H. Roalson, Andrew G. Mccubbin, Richard Whitkus
Aliso: A Journal of Systematic and Floristic Botany
Karyotypic evolution is a prominent feature in the diversification of many plants and animals, yet the role that chromosomal changes play in the process of diversification is still debated. At the diploid level, chromosome fission and/or fusion are necessary components of chromosomal structural change associated with diversification. Yet the genomic features required for these events remain unknown. Here we present an overview of what is known about genomic structure in Cyperales, with particular focus on the current level of understanding of chromosome number and genome size and their impact in a phylogenetic context. We outline ongoing projects exploring genomic structure …

Karyotypes And Idiograms Of Some Western North American Species Of Lotus (Fabaceae), William F. Grant
Aliso: A Journal of Systematic and Floristic Botany
Karyotypes and idiograms are presented for 12 species (L. argophyllus var. argophyllus, L. crassifolius, L. dendroideus var. dendroideus, L. grandifiorus, L. humistratus, L. oblongifolius var. oblongifolius, L. stipularis, L. scoparius var. scoparius, L. salsuginosus var. salsuginosus, L. rigidus, L. wrangelianus, L. wrightii) and 3 varieties (L. argophyllus var. argenteus, L. nevadensis var. douglasii, L. scoparius var. brevialatus) of Lotus L. (Fabaceae) belonging to four different groups of the genus (Hosackia, Syrmatium, Microlotus, and Simpteria). The chromosome number for L. dendroideus var. dendroideus (2n = 14) is reported …
