Two chromosome walks covering 420 and 110 kb on the left arm of linkage group VI (LGVIL) of Neurospora crassa were purscrooued with the goal of cloning carotenogenic loci. Complementation analysis with clones isolated in the 420-kb walk allowed identification of the yellow-1 (ylo-1) gene which is essential for Neurospora carotenogenesis. We have physically located a second gene, unknown-13 (un-13), between the cross-pathway control-1, (cpc-1) and ylo-1 loci. Cloning of a second potential carotenogenic locus, vivid (vvd), from our walks was attempted using screening of Northern blots with radiolabeled DNA fragments from walk clones to identify gene transcripts. The radiolabeled DNA fragments were used to clone complementary DNA isolates representing an additional four genes in the two walks.
