| potato gene y-1 is an n gene homolog that confers cell death upon infection with potato virus y. | adg2 is a dna sequence mapped to a resistance (r) gene-rich region at the distal end of chromosome xi in potato (solanum tuberosum subsp. andigena). the gene, in which adg2 represents the predicted nucleotide-binding domain (nbs), was cloned and characterized. the coding region of the gene (designated as y-1) is 6,187 bp long and structurally similar to gene n that confers hypersensitive resistance to tobacco mosaic virus in nicotiana spp. both belong to the tir-nbs-lrr class of genes and show 5 ... | 2002 | 12118888 |
