Systematic Relationships

Amplified fragment length polymorphisms (AFLP) were utilized to examine systematic relationships in Lathyrus L. sect. Lathyrus (Fabaceae). In addition to a parsimony-based phylogenetic tree, AFLP-based trees were constructed using Dice, Jaccard, and mean character difference coefficients to produce distance-based trees using the UPGMA and neighbor-joining methods. All trees clearly show a close relationship among accessions of the same species, confirming the monophyly of the species examined. All analyses indicate that species of the section Lathyrus are distinct from species of other sections. These findings confirm the monophyly of the section and contradict proposals to split it. They do not support the segregation of L. gorgoni in the section Gorgonia. Within the section Lathyrus, several relationships are present but are only weakly supported. The use of AFLP data to resolve systematic relationships in the genus Lathyrus is further demonstrated.Key words: Lathyrus, Fabaceae, systematics, AFLP.

Pcr Conditions

AFLP is a combination restriction fragment/PCR molecular marker technique which detects polymorphisms due to changes at or in the vicinity of restriction enzyme sites. The technique detects multiple polymorphic loci throughout the genome and may be used for fingerprinting and mapping purposes. The main advantages of the method are the consistency and reliability of the technique due to stringent PCR conditions and the ability to rapidly detect many polymorphic loci.
