Molecular discrimination of lemon cultivars by Bernet, Guillermo P., Mestre, P. F., Pina, José A., Asins, María J.

“…Similar to clementines, polymerase chain reaction (PCR) markers using primers anchored in copya-like retrotransposons resulted in a higher rate of polymorphisms (36.4%) than did primers of random sequence (27.3%) or those anchored at simple sequence repeats (0%), indicating a higher molecular variability at the locations where these retrotransposons inserted. …”
