Expression under the control of Scer\GAL4^eya.enh1+E+2 results in a glossy and small eye phenotype.

At lower expression level (25[o]C), blw^JF02896 driven by Scer\GAL4^VP16.bam does not significantly affect the number of cysts undergoing meiosis I or II. At higher expression levels (29[o]C), there are significantly fewer cysts undergoing meiosis II or containing spermatids, with fewer mature sperm being produced; spermatocytes accumulate at prometaphase I with perturbed nuclear morphologies yet abnormal divisions proceed.

The expression of blw^JF02896 under the control of Scer\GAL4^VP16.bam leads to a significant increase in sister chromatid arm cohesion in S5/6, but not S1, spermatocytes; S5/6 spermatocytes show a significant increase in the number of centrosomes compared to controls.

The expression of blw^JF02896 under the control of Scer\GAL4^Mhc.PW leads to the dorsal longitudinal indirect flight muscles exhibiting mitochondria defects, including abnormal morphology and a significant decrease in electron density in electron microscopy images at 14 and 21 days post eclosion, as compared to controls.
