Nilaparvata lugens is a serious phloem‐feeding pest of rice throughout Asia. Rice phloem sap can meet its nutrition requirement for sugars but not for some essential amino acids such as isoleucine, leucine, methionine, phenylalanine, tryptophan, lysine, arginine and histidine. N. lugens harbours yeast‐like symbionts in mycetocytes formed by abdominal fat body cells. Removal of the symbionts results...
The oxysterol‐binding protein (OSBP) and OSBP‐related proteins (ORPs) are sterol‐binding proteins that may be involved in cellular sterol transportation, sterol metabolism and signal transduction pathways. Four ORP genes were cloned from Aedes aegypti. Based on amino acid sequence homology to human proteins, they are AeOSBP, AeORP1, AeORP8 and AeORP9. Splicing variants of AeOSBP and AeORP8 were identified...
