| sequence variation of bemisia tabaci chemosensory protein 2 in cryptic species b and q: new dna markers for whitefly recognition. | bemisia tabaci gennadius biotypes b and q are two of the most important worldwide agricultural insect pests. genomic sequences of type-2 b. tabaci chemosensory protein (btabcsp2) were cloned and sequenced in b and q biotypes, revealing key biotype-specific variations in the intron sequence. a q260 sequence was found specifically in q-btabcsp2 and cucumis melo ln692399, suggesting ancestral horizontal transfer of gene between the insect and the plant through bacteria. a cleaved amplified polymorp ... | 2016 | 26481237 |
