[Identification and expression pattern analysis of a secretory phospholipase gene in ].

Phospholipase A2 (PLA2) is widely distributed in animals, plants, and microorganisms, and it plays an important role in many physiological activities. In a previous study, we have identified a secretory PLA2 in (). In this study, we further identified four new genes (, , , and ) in .

A secreted phospholipase A (BmsPLA ) regulates melanization of immunity through BmDDC in the silkworm Bombyx mori.

Insect immune-associated phospholipase A (PLA ) is an important target of pathogen invasion. Melanization, an effective defense response, has significant correlations with other immune responses to coordinate immune attack against invaders. However, the effect of PLA on melanization has not yet been reported in insects or other arthropods.
