摘 要:Agrobacteriurn tumefaciens-mediated transformation(AtMT) method was used to study the genetic transformation in Rhizopus arrhizus of antisense expression vector pBI121-fad2 of VeFAD2 *** studied the key factors influencing transformation,such as *** strains,bacterial cell volume initially used,co-cultivation time,effective period and concentration of *** results shows that the ideal *** strain is AGL-1,the optimum bacterial cell volume initially used is 50-100 μL and co-culture 24 hours will get the most *** co-culture period,AS induction is *** is beneficial to improve transformation ratio by adding to 200 μmol·L-1 AS at preincubate period and increasing AS concentration to 400-600 μmol·L-1 at co-culture *** determined that antisense VeFAD2 gene has been integrated into the genome of *** by PCR-Southern detection.
