cultural_requirements: Cytochrome-deficient Mendelian mutations have been subdivided into three main classes as follows (87): cyt, deficiency of more than one cytochrome; cya, deficiency of cytochrome aa3; cyb, deficiency of cytochrome b. Apart from diagnostic spectra, the mutants are characterized by slow growth (4 to 7 days for conidiation of mutants versus 3 days for the wild type) and by the inability to reduce tetrazolium (87). These properties have been used in screening new mutants. cni also affects cytochrome spectra (309). The relation of tet(tetrazolium-resistant nonreducer) to cytochrome mutations is not known. Cytochrome defects that result from mutations of the mitochondrial genome (e.g., [mi-1] and [mi-3]) are not considered here except as they interact with chromosomal genes such as su([mi-1]); see reference 394.
