W22 (C1:R-r:std - PI 674445) Sequence and Assembly. Zea mays subsp. mays cultivar:W22

Whole Genome Sequencing, assembly and annotation of the W22 Zea mays inbred.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).
