Subject: koj and cant alleles The following information comes from correspondence with Paul Adler, University of Virginia, 9/22/99. kojVAI51 and cantWO21 were induced by EMS on FRT-bearing chromosomes. The cant mutation is homozygous lethal. The koj mutation is not lethal, but homozygotes are quite weak. koj maps to 47E and is allelic to shavenoid. shavenoid is a very misleading name since it implies similarity to shaven. In actuality, their phenotypes are completely different. shaven results in a lack of sensory bristles, but has no phenotype in trichomes while shavenoid has no phenotype in bristles but results in a dramatic loss of denticles and trichomes.
