查询词典 polymorphism

RAPD method was used to determine the molecular nature of the variants, and polymorphism, such as OPD05-1250 and OPH16-800 in NaCl-tolerant line of sainfoin and OPA08-1180 and OPH01-760 in ethionine-resistant cell line alfalfa, could be clearly detected among different lines, indicating these variations were caused by the changes in DNA.
