| a transgenic approach to control hemipteran insects by expressing insecticidal genes under phloem-specific promoters. | the first generation transgenic crops used strong constitutive promoters for transgene expression. however, tissue-specific expression is desirable for more precise targeting of transgenes. moreover, piercing/sucking insects, which are generally resistant to insecticidal bacillus thuringiensis (bt) proteins, have emerged as a major pests since the introduction of transgenic crops expressing these toxins. phloem-specific promoters isolated from banana bunchy top virus (bbtv) were used for the exp ... | 2016 | 27708374 |
