The fla14-1 mutant (CC-3937) was rescued by transformation with the wild type LC8 gene. This meiotic product has the NIT1 insertion that deleted the original LC8 gene, and the transformed copy of LC8 that has integrated at a site unlinked to the original locus.

From Patrick Ferris, Washington University, April 2002, his strain K33

Phenotype: requires nicotinamide and thiamine

An imp1 arg2 strain (CC-1865) was transformed with pArg7.8 and a 3.5 kb ApaI fragment containing the MID gene. One of these transformants (B28) was crossed to CC-85 (nic7 mt+) to create a nic7 mt+ strain with a MID transgene. This strain was then crossed to CC-123 (thi10 mt+ ) to create the strains called K33 and L21 (see CC-3948). K33 retains the MID transgene, and although genetically plus, it mates as minus.

Phenotype: chlorophyll deficient, yellow in the dark

This strain is blocked in both the light and dark pathways of protochlorophyllide conversion. It is light-sensitive, and should be maintained in darkness. The PC1 locus corresponds to the gene encoding NADPH:protochlorophyllide oxidoreductase. The gene represented by the y1 mutation has not yet been identified.
