From Gianni Piperno, Rockefeller University, June 1990

Phenotype: uniflagellate

This mutant was induced by ICR-191 mutagenesis in the 137c background by Huang and colleagues in Luck’s laboratory. Huang et al. called it uni4, but showed that it was allelic with uni1.

Phenotype: requires acetate

FUD39 is a mutation in the PSBP gene encoding protein OEE2. Despite isolation following 5-fluorodeoxyuridine treatment, which is generally considered to act preferentially on chloroplast DNA, this is a nuclear mutation.

CC-4142 and CC-4143 are more recently acquired stocks of this mutant.

From the Culture Centre of Algae and Protozoa (CCAP), August 1990

This is a mutant of C. moewusii isolated by Lewin, his strain RAL#7. The M.475 mutant was described as paralyzed, and slow to regenerate flagella after deflagellation. This mutant is also in the collection as CC-957, and CC-1482 and in combination with M.1051 as CC-1500.

This strain came originally from Lewin, but is not otherwise identified. The LM numbers were Lewin’s internal stock numbers, and not intended for publication, but CCAP had no other information on this strain.

From Jonathan Jarvik, Carnegie-Mellon University, October 1990

Phenotype: variable number of flagella

This mutant has a variable number of flagella, usually zero to six. The flagella are of normal length, and the cells appear to be of normal size and shape. The mutation was UV-induced in strain ‘NO mt+’ (equivalent to CC-620) by Kuchka and Jarvik, originally vfl-2-220. Taillon et al. determined that vfl2 is a G to A transition mutation in the structural gene for centrin, producing a Glu to Lys change at position 101, the first amino acid of the E-helix of the protein’s third EF-hand.
