heterozygous females show the expected mating-induced increase in germline stem cells in the germarium.
mesothoracic tergum & macrochaeta | ectopic tkv1
flies occasionally display ectopic bristles anterior to the anterior dorso-central bristle, when raised at 18o
animals survive until the third larval instar and show a dramatic reduction in neuromuscular junction (NMJ) size compared to wild type. tkv1
animals show a significant reduction in neuromuscular junction (NMJ) size compared to wild type; the number of synaptic boutons/muscle surface area at muscle 6/7 is 71.6 +/- 1.9% of wild type. The evoked excitatory junctional potential (EJP) (measured at muscle 6 of segment A3) shows a decrease in amplitude in tkv1
animals compared to wild type. Quantal content is reduced compared to wild type.
Heterozygotes show a quantitative effect on wing shape in intervein regions B and C compared to wild type.
flies have variable thickening of the wing veins, particularly in regions close to the cross veins and at the distal ends of all longitudinal veins. tkv1
flies have some wing vein thickening, and lack distal stretches of vein LIV.
Thickening and abnormal branching of the wing veins in the region of intersection with the crossveins and near the ends of the longitudinal veins.
Homozygotes have a weak phenotype, hemizygotes have thickening of longitudinal and transverse veins.
homozygous viable with thick veins Veins thickened and branched in region of crossveins, near end of L2, and elsewhere. Sometimes a blister near posterior crossvein in female; L4 sometimes shortened, especially in female. Female more extreme than male. Easier to identify at 19oC. RK2.
