[Edgley M] Reciprocal translocation. Suppresses recombination on left arm of LG V and right arm of LG III. Breaks in unc-36. Homozygous viable with Unc-36 phenotype. | ||||
20-bp sequences of either side of the eT1 breakpoints are as follows, eT1(V): aataatttttgaaacaaaaa-GTTTATCATCTCAAGACGTG; eT1(III): GAGCCAATCACTTACTGGTTAGTAATGATTCCAAATATGAGCCAATCACTTACTGGTTAGTAATGATTCCAAA-cttgattccaaatatgacat | Paper_evidence | WBPaper00027674 | ||
Phenotype: Unc | ||||
Summary: Reciprocal translocation, well characterized, extremely stable. Very effective balancer for left portion of LG V from left end through unc-23, and right portion of LG III from right end to unc-36. eT1(III) is LG V (left) translocated to LG III (left), disjoins from normal LG III. eT1(V) is LG III (right) translocated to LG V (right), disjoins from normal LG V. Zhao et al. reports the sequence of the physical breakpoint of eT1 on chromosome V (the breakpoint of eT1 chromosome III is in the unc-36 gene). | Paper_evidence | WBPaper00029020 | ||
Growth characteristics: Original isolate homozygous viable with Unc-36 phenotype caused by the translocation breakpoint. Brood size in heterozygotes ~ 100, in homozygotes ~160. eT1 homozygotes can overgrow a population, especially in balanced strains carrying certain lethal mutations or deficiencies. | Paper_evidence | WBPaper00029020 | ||
Handling: Easy to manipulate. Heterozygous male stock mate well. | Paper_evidence | WBPaper00029020 | ||
Recommended use: General balancing, strain construction, strain maintenance, and mutant screens. | Paper_evidence | WBPaper00029020 | ||
