Table I. Rosette fresh biomass and chlorophyll fluorescence of 8-week-old wild-type and nramp3nramp4 plants grown on perlite in the presence (control; 5 μm Mn) or absence of Mn (−Mn)

Results shown correspond to means ± se with n number of plants weighted and n′ number of F_v/F_m measurements on different leaves. Results from one representative experiment out of five are shown. Asterisks denote significant differences based on Mann-Whitney U test: ** P < 0.01, * P < 0.05.
