Chlamydomonas Genetics Center, Duke University, February 1981

Phenotype: resistant to antibiotics and metabolic inhibitors (cycloheximide, methionine sulfoximine, neamine, pyrithiamine, and streptomycin)

From a cross of CC-975, a multiply marked strain, to CC-919, a wild type strain with nitrate reductase activity.

This was created as a multiply marked strain in a nit+ background, free of auxotrophic and pf markers. Although CC-1144 swims normally, some progeny in crosses seem to have impaired motility, suggesting that it may actually contain pf2 from the CC-975 parent strain, plus a segregating suppressor. CC-1144 carries the wild type alleles at both the NIT1 and NIT2 loci, and can therefore grow on nitrate medium.
