Figure 1From: TaMSH7: A cereal mismatch repair gene that affects fertility in transgenic barley (Hordeum vulgare L.)MSH7 sequence alignments. (A) Three distinct sets of TaMSH7 sequences were identified which are representative of the three bread wheat genomes (A, B and D). The T. tauschii (Tt) sequence, CS D sequence and the N3B T3Ad sequence represent the D genome. The N3B T3Aa and CS A sequences represent the A genome, while the remaining sequence (CS B) represents the B genome. (B) The majority of differences in the sub-genomic amino acid sequence were at non-conserved residues. One change Leu → Ser at residue 596 of genome B (pink) was at a residue that is conserved amongst other MSH7 and MSH6 proteins and the prokaryotic homologue, MutS. (C) Two differences in amino acid sequence between the CS and ph2b D genome sequences were identified (pink). Both these amino acids were present in other MSH7 proteins.Back to article page
