Chromosome studies of Mexican alpine plants

, : Chromosome studies of Mexican alpine plants. Brittonia 12(3): 226-230

Cytological studies were made of 16 species in 11 genera and 5 families in the alpine flora of Mexico. Only one of these spp. (Eryngium carlinae) has received previous chromosomal study, and the 1st record of a chromosome count in the genus Oxylobus (n=16) is included. Meiotic chromosome counts are reported for 15 spp., and the mitotic count of 1 sp. is given. Eight spp. appear to be polyploid, 3 spp. have the lowest chromosome number known in their genera, and 4 spp. have numbers slightly higher than the lowest known number in their genera.

To better understand the role of these two proteins in homologous recombination in the RecF pathway...
