Effect of abiotic stresses on the growth of OX lines. Growth of transgenic lines with increased OsALMT4 expression (OX5 and OX2) and null lines (OX5_null and OX2_null) was measured after longer-term treatments in various abiotic stresses. Data show the relative growth (biomass in treatment/biomass in control) for each line after 28 days in a growth chamber in hydroponics with and without (A) 100 mM NaCl, (B) 50 mM mannitol or (C) low-Cl- solution. In separate experiments shown in (D) plants were grown for 56 days in soil in growth chambers where the maximum diurnal light intensity was either 700 μmol m-2s-1 (control) or 300 μmol m-2s-1 (low). Results show total biomass in (A–C) whereas shoot biomass is shown in (D). Results show mean and SE (n = 4–6). Biomass data is shown in Supplementary Table S1. The combined data from the RNAi lines were significantly different from the combined data from the null lines for the low light treatment only (P < 0.05) using a t-test test as shown.
