In order to know if the reduction in survival of the asrij null flies upon infection is solely due to defect in the hematopoietic system or due to reduction of overall tolerance of the flies, we depleted Asrij specifically in the hemocytes using Hemolectin-Gal4 (HmlGal4) or trachea using breathless-Gal4 (btlGal4) where Asrij was also seen to be expressed in the embryo41. This evidence concerns the gene LGALS4 and infection.
