Effect of T1 transgenic cotton on larvae growth. a The dsRNA construct pBI121-dsCYP6AE14 contained a 35S promoter, a sense fragment of CYP6AE14 cDNA from +472 to +940, a 120-nucleotide intron of Arabidopsis RTM1 gene (Johansen and Carrington 2001), the CYP6AE14 fragment in antisense orientation, and a NOS terminator. b northern blot detection of dsRNA homologues to CYP6AE14 in the leaves of transgenic (ds1-ds6) and nontransgenic control (R15) plants. c, d Net weight increase of larvae reared on leaves of T1 transgenic cotton plants. Third-instar larvae previously grown on artificial diet were transferred to nontransgenic (R15) or T1 transgenic cotton plant leaves for 4 days, respectively. Values are means ± standard deviation (SD). *P < 0.05; **P < 0.01
