Genetic relationships between Lophopyrum elongatum and Dasypyrum villosum (Triticeae - Poaceae) as revealed by isoenzymes
Genetic relationships between Lophopyrum elongatum and Dasypyrum villosum (Triticeae - Poaceae) as revealed by isoenzymes
Polyacrylamide gel electrophoresis was used to reveal genetic relationships between Lophopyrum elongatum and Dasypyrum villosum. Allozymes indicated that gene diversity oceurrs primarily within than between populations of both taxa. Unbiased genetic identities (1) and distances (D) were calculated. Pairwise comparisons between populations of L. elongatum and D. villosum resulted in mean value of D equal to 0.889 - an indication that Lophopyrum and Dasypyrum are distantly related within the tribe Triticeae. The present isoenzyme study tended 10 support data derived from nuclear DNA sequences but it is incongruent with data from chloroplast DNA sequencing.
