The glue that builds bristles

n actin cable is the sum of its parts, according to Guild et al. (page 1069), who find that short bundles of actin filaments are grafted together to form extra long actin cables in fly bristle cells. Bristle cells, which can reach lengths of up to 400 ␮ m, are initially supported by an assembly of multiple short stretches of polarized actin bundles. By looking closely at these bundles as they b...

iroquois: a prepattern gene that controls the formation of bristles on the thorax ofDrosophila

We have isolated a Drosophila mutant where the lateral parts of the notum are completely naked, leaving unaffected a median stripe of hairs. This mutation, iroquois (iro), defines a new gene which maps at 69D. We show that, in the presumptive lateral notum of mutant discs, sense organ precursor cells fail to form and the proneural gene scute is not expressed. The expression of a reporter gene i...
