carbohydrate

locus: car

locus_name: carbohydrate

organism_type: B

chromosome_number: IV

chromosome_side: L

link_group: IVL

cultural_requirements: IVL. Linked to cys-10 (1%) (435). Altered morphological rhythm associated with a deficiency in low-affinity glucose transport system. On glucose, the mutant car produces dense and sparse mycelia in cycles (period, ca. 50 h). Originated from a cross between pat and acu-7, but acu-7 is not necessary for the phenotype. Periodicity is affected by composition of the medium rather than time, so that the cycle is not circadian as in bd or patmutants. On acetate, the mutant car is insensitive to the light/dark cycle and has a normal conidiation cycle with a period of about 24 h. Called LPcar: long-period carbohydrate (435). The symbol car was also used formerly for some carotenoid mutations, at least one of which is an al-2 allele (1041), and for a carbohydrate mutation (1030) strain not available for testing.
