| Popis: | Using a PCR approach, we showed that puroindoline genes are present in diploid and hexaploid Triticum species but absent in tetraploid species, and that T. tauschii is likely to be the donor of the T. aestivum puroindoline genes. Puroindoline-like genes are present in cereals closely related to wheat (barley, oat and rye) and absent in cereals more distantly related to wheat (maize, rice and sorghum). Barley, oat and rye puroindoline-like sequences and primary structure of deduced proteins are highly conserved. In oat, avenoindolines are more closely related to puroindolines than to tryptophanins. |
