| 英文摘要 | among 20 awnless tibetan wheat cultivars analyzed by sds-page, the migration rate of an hmw-gs in xm001584 and xm001593, named 1bx23*. was shown to be slightly faster than 1bx6. and slower than bx7. its nucleotide sequence was isolated based on homology clones. in a phylogenetic tree of 1bx genes, 1bx23* was apparently clustered with 1bx23. compared with 1bx23. eight single nucleotide replacements caused four single amino acid replacements in 1bx23*. the deletion of "g" at base pair 1463 and insertion of "a" at 1509 bps induced a 42-nucleotide frame shift. "gqrqqagqwqrpgq" was replaced by "dkgnrqdngndrdk". the new segment cannot be found in other hmw-gss, and it is very similar to a segment found in collagen. moreover, an 18-nucleotide deletion made 1bx23* six amino acids shorter than 1bx23. the cultivar xm001593 had 28 chromosomes, which signifies that it was tetraploid wheat, and that the new hmw-gs1bx23* cannot be used directly for breeding in common wheat. |
