CC-1097 arg4? mt-
$30.00
Chlamydomonas Genetics Center, Duke University, 1980
Phenotype: requires arginine
This strain was derived as follows:
CC-125 wild type mt+ was crossed to CC-10, the original arg4 stock in our collection. This cross gave many incomplete tetrads. An arginine-requiring product was then back-crossed to CC-125, and two products selected that became CC-1097 arg4 mt- and CC-1098 arg4 mt+. However, in a subsequent test cross to CC-1084 ac9, the expected linkage was not observed, and we are therefore concerned that this isn’t really arg4. For better arg4 strains, and more on the ARG4 locus, please see CC-1997.
