Extensive ribosomal DNA genic variation in the columnar cactus Lophocereus.

Journal of molecular evolution - 1 Aug 2001

Hartmann S, Nason J D, Bhattacharya D

Abstract excerpt

Sequence analysis of the hypervariable internal transcribed spacer (ITS) regions of ribosomal DNA (rDNA) is commonly used to gain insights into plant and animal population structure and phylogeny. We characterized ITS1, ITS2, and the 5.8S coding region of 18 senita (Lophocereus) individuals from 12 different populations in Baja as well as from closely related cactus species. Analyses of multiple clones...
