Differences in sucrose metabolism among extracted tetraploid wheat (ETW), its common wheat donor (line TAA10, genome BBAADD), Ae. tauschii (line TQ18), an extant tetraploid wheat line (line ALTAR81, genome BBAA), and a resynthesized allohexaploid wheat (XX329, genome BBAADD) obtained by crossing ETW (maternal parent) and TQ18 (paternal parent). a Sucrose content. b Expression of genes involved in sugar metabolism. The expressional values are means of four biological replicates. c Changes in sucrose metabolism network of ETW. Asterisks indicate significant differences (t-test, P < 0.05) between ETW and each wheat line.
