Root transcriptional profile of maize seedlings supplied with FePO4 nanoparticles as source of Fe and P.. Root transcriptional profile of maize seedlings supplied with FePO4 nanoparticles as source of Fe and P.

FePO4 nanoparticles (NPs) were used as source of Fe and P for the growth of maize seedlings. Through a series of transcriptional profiles comparison of plants treated with FePO4 NPs, bulk FePO4 (non-nanometric ) and Fe-deficient and P-deficient plants, transcripts speciffically modulated by NPs as source of Fe and P were identified. Overall design: Twenty-one root samples were analyzed: 3 biological relicates for each of the seven treatement (C, -P, PNP, PB, -Fe, FeNP and FeB).
