Normalisation of the res tomato mutant phenotype. (a) Comparison of WT and res seedlings (left) and leaves of adult plants (right) in absence of salt stress. (b) Phenotypic changes provoked by salt treatment (5 days at 200 mM NaCl) in roots and leaves of res. (c) Chlorophyll content (SPAD), photosynthetic efficiency (Fv/Fm) and MDA content measured in WT (white bars) and res (red bars) leaves under control conditions (plain coloured bars) and after 5 days of salt stress (dashed coloured bars). Values are means ± SE of three biological replicates. Different letters indicate significant differences between means by LSD test (P < 0.05)
