Growth of Thellungiella seedlings exposed to nitrogen deficit and/or salt stress. A) Representative Thellungiella salsuginea (Ts) and Arabidopsis thaliana (At) seedlings grown on media containing 1 mM or 0.1 mM nitrogen (HN and LN, respectively) in the presence (+S) or absence (-S) of 100 mM NaCl. Scale bars = 6.5 mm. B) Primary root elongation kinetics of Thellungiella seedlings. Treatments shown are: HN, ■; LN, ▴; HN + S, □; LN + S, ▵. Root measurements were taken at the same time daily. All data are presented as the mean ± SE of 40 seedlings per measurement across three biological replicates. Growth rates for roots of seedlings grown in the presence or absence of NaCl are presented in mm·d^-1. C) The extent of Thellungiella shoot biomass and root length at harvest after growing on media containing varying concentrations of nitrogen and salt.
