Project description:We investigate the functional complexity of the Plutella xylostella transcriptome in defending against a Bt toxin using Illumina sequencing technology. Over 2,900 differentially expressed unigenes were obtained in resistant P. xylostella comparison to their susceptible counterpart. All the P. xylostella were maintained on cabbage.The susceptible strain (MM) was cultured without exposure to any Bt toxins.Before the sample collected, Cry1Ac-resistant P. xylostella were treated with 750μg/mL Bt toxin Cry1Ac to eliminate the heterozygous individuals. Then the survivors were collected after 48 hours and designed as the resistant sample (MK and GK). Then fourth-instars larvae midgut tissues of MK,GK and MM were collected, respectively, The RNA was extracted and sequenced using Illunima HiSeq 2000.
