The mps1 mitotic recombination groups

Group	Members	Nonpermissive temperature	Intragenic complementation
I	1*, 773, 1169	30°C
II	412*, 585, 688	34°C	With 737
III	737*	34°C	With 412, 3796
IV	422, 502, 676, 1237*, 3497, 3704	34°C
V	3796*	34°C	With 737
	6*	30°C

The 14 isolates were subdivided into five mitotic recombination groups. One isolate, mps1-6, was not examined by this method. The representative of each group that was chosen for further analysis is marked with an asterisk. When mps1-737 is combined with either mps1-412 or mps1-3796 in a diploid cell, partial intragenic complementation occurs. The diploid can now grow at 36-37°C, which is normally lethal for each allele alone. These diploids remain ts at 38°C.
