Abstract
To examine variation in phytosiderophore biosynthesis in Triticeae, phytosiderophores were investigated in wild and cultivated species of wheat and barley with different genomes. All wheats tested including hexaploid (AABBDD), tetraploid (AABB), and diploid (AA or DD) lines produced only one phytosiderophore, 2'-deoxymugineic acid. The phytosiderophores biosynthesized in wild barleys varied among species. Using substitution-type triticale lines and wheat-barley addition lines, it was revealed that, in triticale, genes for the biosynthesis of both mugineic and hydroxymugineic acids were located in the long arm of chromosome 5R and that, in barley, the gene for production of mugineic acid was located in the long arm of chromosome 4H.
