Molecular Cloning and Expression Patterns of a Serpin-2 from the Beet Armyworm, Spodoptera exigua

다국어 초록 (Multilingual Abstract)

Serpins are known to play a critical role in insect imunity and physiology. Here, we present a 1,296 nucleotide sequence of a serpin gene from the beet armyworm, Spodoptera exigua ing the conserved reactive center loop (RCL) residues found in serpin, and has the highest identity to Bombyx mori serpin-2 (67%). In addition, it has a homology to serpins of other insects such as Lonomia obliqua (6%), Manduca sexta (52%), and Plutella xylostella (41%). RT-PCR analysis eichoic acid (LTA), whereas SeCecropinB i s i n d u c e d u n d e r t h e s a m e c o n d i t i o n . I n a d i t i o n , i t i s n o t i nduced by nucleopolyhedrosis virus of S. exigua (SeNPV), whereas SeCecropinB and inhibitor of apoptosis (SeNPV-IAP) are induced by SeNPV infection. The lack of dramatic induction of S. exigua t i t m a y h a v e a n unknown function during the developmental stages albeit it remains to be further elucidated.
