General Information

EC Number General Information Comment Organism
3.1.1.7 malfunction silencing of Tcace1 and Tcace2 by RNA interference significantly increases the susceptibility of Toxoptera citricidus to malathion and carbaryl, silencing of isozyme Tcace1 results in a higher mortality rate than silencing of isozyme Tcace2. Additionally, the specific enzyme activity decreases more after silencing Tcace1 than after silencing Tcace2 Aphis citricidus
