Ethylene regulation of root growth and phytosiderophore biosynthesis determines iron deficiency tolerance in wheat (Triticum spp)

Two separate experiments were conducted with four bread and two durum wheat cultivars, to test a hypothesis that high ethylene production will alter phytosiderophore production and release dynamics either directly, by competitive partitioning of SAM, or indirectly by causing changes in the root system architecture under iron deficiency. A significant decline in the leaf greenness index confirmed the Fe deficiency response across the wheat...
