Key to plant pH homeostasis plus 3-6x enhanced iron uptake

Proven to increase yield in extensive rice field trials.  Far reaching effects on plant performance via unexpected key role in pH homeostasis, plus 3-6x enhanced iron uptake.  Shown to work in tobacco and Arabidopsis.  Suitable to deploy to crop species. 

NEW 2019: The inventors have generated non-transgenic mutants of rice with high expression of the OsNRT2.3b gene – directly available for conventional breeding (Tech Id 16.614).
