Fig. 1.

Wheat NPR1‐like genes and organisation and structures of the proteins. (a) Genomic blot (Southern) hybridisation result from genomic DNA of seven wheat NT lines and W3SNPR1 as a probe. Lines indicate the chromosome location of each fragment. (b) Arrangement and structures of six NPR1 homologues in wheat group 3 chromosomes. One dashed box represents one predicted gene and the arrow under each box indicates the orientation of the gene. The distance between the two NPR1 homologues in the same chromosome is indicated in base pairs, but not related to the scale in the figure. Each coloured box represents a region of a known functional domain. BTB: Broad complex, Tramtrack and Bric‐à‐brac; UK: DUF3420 unknown domain; Ank: Ankyrin repeats; NPR1_like_C: A region conserved at the NPR1 C‐terminal; PKinase: Protein Kinase. The sizes of the domains are not according to scale. (c) Arrangement and structures of the three NPR1 homologues and the three NB‐CC‐like genes in wheat chromosomes 7A, 7D and 4A(7B).
