Site-directed mutagenesis (T1149A, Y1150A) of AGO2 (RP98-21A13 from BACPAC Resources Center) under the control of the endogenous promoter.
The loss of RNA interference functionality characteristic for AGO251B mutants and manifested by their retaining red eye color upon expression of wdsRNA.GMR is only partially rescued by combination with AGO2m1 and results in light red eye color.
