Molecular-based characterization and bioengineering of Sorghum bicolor to enhance iron deficiency tolerance in iron-limiting calcareous soils.

Plant biomass can significantly contribute to alternative energy sources. Sorghum bicolor is a promising plant for producing energy, but is susceptible to iron deficiency, which inhibits its cultivation in iron-limiting calcareous soils. The molecular basis for the susceptibility of sorghum to iron deficiency remains unclear.
