SPARC plays an important role in the oviposition and nymphal development in Nilaparvata lugens Stal.

ABSTRACT:

Background

The brown planthopper (Nilaparvata lugens Stål)is a notorious rice pest in many areas of Asia. Study on the molecular mechanisms underlying its development and reproduction will provide scientific basis for effective control. SPARC (Secreted Protein, Acidic and Rich in Cysteine) is one of structural component of the extracellular matrix, which influences a diverse array of biological functions. In this study, the gene for SPARC was identified and functionally analysed from N.lugens.

Results

The result showed that the NlSPARC mRNA was highly expressed in fat body, hemolymph and early embryo. The mortality increased significantly when NlSPARC was downregulated after RNA interference (RNAi) in 3 ~ 4^th instar nymphs. Downregulation of NlSPARC in adults sign
