Subject: DTS91
Dated:  Oct 24, 1994
Background:  A Bloomington stock received from Ted Wright contains a mutation he called DTS-91, now DTS91.  No published reference was found
so Ted was queried about the identify of this DTS.  
Information communicated:  
DTS91 was received from Dave Suzuki 1/18/69. Suzuki stated that DTS91 is located in the dp-b region close to clot - 'very
tight' - and DTS91/DTS91 dies at room temp. Whether the recessive lethality is caused by DTS91 or by other lethals on the chromosome is not known.
Its location suggests that DTS91 is an allele of the group of dominant cold sensitive mutants that Suzuki's lab isolated around the same time
(see Rosenbluth et al. 1972 Genetics  70:75-86 ; see also Suzuki and Procunier 1969 PNAS  62:369-376 ), although Suzuki was not able to
provide the new designation (used in the publication) for DTS91. The conclusion is that DTS91 is one of the 11 DTSs that mapped between
dp and b reported in the Suzuki-Procunier paper.  None of the DTSs listed in the Red Book map between dp and b, so DTS91 may be the
only survivor from this region of Suzuki and Procunier's work.
