Subject: bel alleles Personal communication from: Kathy Matthews, Indiana University Subject: bel alleles Dated: 12 April 2001 Information communicated: belM2 EMS-induced on kniri-1 e1, selected for lethality with bel6. Fails to complement Df(3R)p13. belM2/Df(3R)Antp17, alphaTub67CRE1.1 heterozygotes, which have half the normal complement of wild-type maternally-expressed alpha-tubulin genes, are semi-sterile. belM3 EMS-induced on kniri-1 e1, selected for lethality with bel6. Fails to complement Df(3R)p13. belM3/Df(3R)Antp17, alphaTub67CRE1.1 heterozygotes, which have half the normal complement of wild-type maternally-expressed alpha-tubulin genes, are semi-sterile. belM4 EMS-induced on kniri-1 e1, selected for lethality with bel6. Fails to complement Df(3R)p13. Fertility of belM4/Df(3R)Antp17, alphaTub67CRE1.1 heterozygotes, which have half the normal complement of wild-type maternally- expressed alpha-tubulin genes, is good relative to that of comparable heterozygotes with belM2 and belM3.
