Insights into the transcriptomics of polyphagy: Bemisia tabaci adaptability to phenylpropanoids involves coordinated expression of defense and metabolic genes

ABSTRACT: Background: The whitefly Bemisia tabaci is a major generalist agricultural pest of field and horticultural crops world-wide. Despite its importance, the molecular bases of defense mechanisms in B. tabaci against major plant secondary defense compounds, such as the phenylpropanoids, remain unknown. Results: Our experimental system utilized transgenic Nicotiana tabacum plants constitutively expressing the PAP1 M-bM-^AM-^D AtMYB75 transcription factor which activates specifically the phenylpropanoid / flavonoids biosynthetic pathway. Our study used suppression subtractive hybridization (SSH) and cDNA microarray approaches to compare gene expression between B. tabaci adults subjected to wild-type or transgenic plants for six hours. A total of 2880 clones from the SSH libraries were sequenced.
