Transcriptome analysis of iron and phosphorus interaction in rice seedlings

The antagonistic interaction between iron (Fe) and phosphorus (P) has been noted in the area of plant nutrition. To understand the physiology and molecular mechanisms of this interaction, we studied the growth performance, nutrient concentration, and gene expression profiles of root and shoot segments derived from 10-d-old rice (Oryza sativa) seedlings under four different nutrient conditions: (1) full strength of Fe and P (+Fe+P); (2) full strength of P and no Fe (-Fe+P); (3) full strength of Fe and no P (+Fe-P); and (4) without both Fe and P (-Fe-P).
