Functional conservation of the fruitless male sex-determination gene across 250 Myr of insect evolution.

abstract：:Silks are strong protein fibers produced by a broad array of spiders and insects. The vast majority of known silks are large, repetitive proteins assembled into extended beta-sheet structures. Honeybees, however, have found a radically different evolutionary solution to the need for a building material. The 4 fibrous ...
