Flagellar-length mutants used in the current study with the relevant information as cited in literature

Cell type	Allele	Protein (kDa)	Phenotype	Flagella length (μm)	Reference
WT	–	–	Normal length flagella	10 to 12	[29]
CC-802	lf1-1	88	Flagella 3× WT	Never exceeds 32	[27]
			Re-grows very slowly after amputation
			Novel protein - Glycine-rich
CC-803	lf2-1	38	Unequal length flagella and do not regenerate their flagella. Results in a truncated protein product (Cyclin-dependent PK)	18 to 22	[26, 28]
CC-2287	lf2-5	26	Retains partial functions, hypomorphic, regenerates with normal kinetics	17 ± 2.2	[28]
CC-3662	lf3-2	133	Flagella 1.5–2×, <15% of the population with stumpy flagella, 30–80% with long flagella; novel protein (contains an amber mutation, truncated product)	19 to 24	[28]
lf4	lf4	63	Null mutants of lf4 show almost two-fold increase in the lengths of the flagella; gene encodes a MAPK	23 to 28	Gift from P. A. Lefebvre [25]
