Identificação por PCR dos alelos-S associados à compatibilidade gametofítica em ameixeira japonesa

Abstract: Resumo -O objetivo deste trabalho foi identificar e caracterizar molecularmente os alelos-S de cultivares de ameixeira japonesa e verificar a compatibilidade gametofítica entre estes. Foram utilizados dois pares de iniciadores específicos na amplificação dos alelos via PCR, em 18 cultivares: Pluma 7, Gulf Rubi, Blood Plum, Wickson, América, Santa Rosa, Rosa Mineira, Estrela Púrpura, Amarelinha, The First, Harry Pieckstone, Santa Rita, Seleção 16, Seleção A26 (Burbank), Seleção 21, Seleção 19, Methley e Simka. … Show more

“…The identification and characterization of the allelic series (S-alleles), which is named 'S 1 ', 'S 2 ', 'S 3 ', 'S 4 ', and 'S 5 ' or 'S a ', 'S h ', 'S i ', 'S c ', and 'S e ', that encode the RNases in the stigma of the Japanese Plum cultivars, can help to manage orchards, since the cultivation of genotypes with different alleles may increase fertilization and effective fruit set (Ushijima et al, 1998;De Nettancourt, 2001;Kondo et al, 2002;De Conti et al, 2013;Sassa, 2016). Molecular studies to understand the reproductive process in Prunus species are focused on the identification and characterization of S-RNases genes through tools like Polymerase Chain Reaction (PCR) and DNA sequencing.…”
