Dear Colleagues:
I'm trying to locate seeds related to the sh-m5933 allele isolated by
Barbara McClintock. If you have information about these stocks, please
read on:
My name is Jianbo Zhang, and I am a postdoc in Thomas Peterson's laboratory
at Iowa State University. I would like to compare the structures of
sh-m5933 and its progenitor in order to test models for unconventional
transposition mechanisms. There are 4 stocks carrying DsI in chromosome 9
in Maize Stock Center, but it is not known which one is the
progenitor. Dr. McClintock described an allele named 5933-I in Carnegie
Institution of Washington Year Book No. 51 (page 217); its phenotype is
similar to that of sh-m5933. If 5933-I is sh-m5933, then the progenitor of
sh-m5933 should be Ds 5245. If you have Ds 4864A, the Ds element in
standard location, and sh-m6258, I would also like to have them.
Please contact me if you have any seeds or information about these
stocks. Thanks.
Jianbo
