抄録

Hordatines A and B, strong antifungal components in shoots of barley seedlings, were found to occur in a barley chromosome 2H addition line to wheat, but not in a wheat line carrying the long arm of chromosome 2H. These results showed that some genes that encode hordatine biosynthetic enzymes are located on the short arm of chromosome 2H. The total content of the hordatines was about six fold less than that in the parental barley, but was still at a concentration more than 20-fold higher than that required for inhibition of spore germination of pathogenic fungi.<br>
