Genomic fragment containing the Atg9 transcription unit flanked by 1kb of both upstream and downstream sequence.
The near lethality of Atg9Gal4KO/Atg9d51 transheterozygotes and of Atg9Gal4KO homozygotes is rescued by Atg9+tgr. Atg9+tgr also rescues the short lived phenotype, the defects in adult locomotion, the defects in the adult midgut (i.e. defects in length and thickness, in the visceral mesoderm layer, in the epithelial barrier function as shown by the abnormal permeability to a non-absorbable food dye, and in cell size), and the defects in autophagy (i.e. abnormal accumulation of ubiquitinated protein aggregates in adult thoracic muscles and both the developmental and starvation-induced autophagy in the larval and adult fat body, respectively) exhibited by Atg9Gal4KO/Atg9d51 transheterozygotes.
