Stock provided by Hugo Dooner. This stock was derived by R.A. Brink at the U. of Wisconsin for his studies on paramutation at the R locus by five back-crosses of the regular W22 inbred (colorless seed because of c1; r alleles) to a purple seed stock that he apparently obtained from Cornell (Brink, 1956, Genetics 41:872-889). This resulted in the introgression of C1 and R alleles from the purple stock into W22. The C1 allele was characterized by Karen Cone. The R allele is the paramutable R-r: standard allele (Brink, 1956, op. cit.; Dooner & Kermicle, 1971, Genetics 67:427-436). Allele was obtained in 1972 from the U. of Wisconsin cold storage collection (pedigree CS-810) and has been selfed for 30 generations. Known alleles of color genes: C1 (Cooper and Cone, unpub.; GenBank AF320614); R-r: std (Walker et al., 1995, EMBO J. 10: 2360-2363; only partial sequence); Bz1-W22 (Dooner & He, 2008, Plant Cell 20:249-258; GenBank EU338354).
