In combination with other aberrations

Df(3R)Tl-I/Df(3R)D605 flies are viable and fertile.

Df(3R)Tl-I/Df(3R)D605 flies show a normal humoral response.

Df(3R)Tl-I/Df(3R)D605 flies show strongly impaired levels of phagocytosis of gram-positive bacteria compared to wild-type or heterozygous controls. These flies also show an impairment in phagocytosis of gram-negative bacteria, althoughh to a lesser extent.

Df(3R)Tl-I/Df(3R)D605 hemocytes show impaired levels of phagocytosis of both gram-positive and gram-negative bacteria, but show wild-type levels of phagocytosis of india ink carbon particles. These hemocytes appear to adhere less tightly to the larval cuticle than wild-type hemocytes.

After feeding on gram-negative bacteria, Df(3R)Tl-I/Df(3R)D605 flies die more rapidly than wild-type flies. The hemolymph of these flies contains about a 10,000-fold increase in bacterial number compared to wild-type flies.

Inferred to overlap with: Df(3R)Espl3.

NOT in combination with other aberrations

Df(3R)D605/Df(3R)Tl-I flies ("eater null" flies) exhibit increased susceptibility to R.oryzae as compared to control wild-type flies.

Injection of spz1.9 or spz2.1 transcripts rescues spz4/Df(3R)Tl-I embryos to hatching, injection of spz2.2 weakly rescues and spz1.8 fails to rescue.
