RNAs from different tissues (fat body, midgut, and Malpighian tubules of adults), as well as 1st- and 2nd-instar larvae, were isolated by using RNeasy[R] Plus Micro Kit with Qiageng DNA Eliminator spin column (Qiagen, Hilden, Germany).
Trehalase2 activity found in the midgut, Malpighian tubules and fat body was 0.
This pathogen primarily infects the Malpighian tubules but often spreads systemically (Andreadis & Hanula 1987).
Total RNA was isolated from different tissues (fat body, gut, Malpighian tubule and trachea of the third instar larvae), 1- and 4-d larvae, using RNeasy[R] Plus Micro Kit with gDNA Eliminator spin column (Qiagen, Hilden, Germany).
The expression levels of BdEcR-Bl in the gut and the Malpighian tubule greatly exceeded those in the trachea and fat body.
The digestive tracts were divided into the foregut, midgut, ileum, rectum, and Malpighian tubules.
What we observed was quite intriguing: in Celera, Cyp6g1 was expressed in the midgut, the Malpighian tubules and the fat body, the tissues 'traditionally' associated with the detoxification of xenobiotics.
