Description

Hsp26 sequences from -1917bp to +632bp are fused upstream of lacZ.

(Lu et al., 1992)

2.6kb PvuII fragment of Hsp26 promoter sequences containing 2kb of upstream sequence and 0.6kb of the Hsp26 gene is fused upstream of lacZ.

Additional Information
Statement
Reference

In absence of heat shock, strongly expressed in spermatocytes, nurse cells (strongest in stage S10), and in epithelial cells of imaginal discs; lower levels of expression in the proventriculus, and in neurocytes of the larval brain and ventral ganglion.
