a Expression levels of PP2-1 in leaves of cold-stressed S. habrochaites (LA1777) and S. lycopersicum (AC). b Expression patterns of ShPP2-1 in different tissues collected from four-week-old seedlings of LA1777. c–e Expression pattern of ShPP2-1 in drought-, salt-, and heat-stressed LA1777 seedlings. For a and c, four-week-old seedlings were stressed with cold (4 °C), drought (dehydration), salt (200 mM NaCl), or heat (40 °C °C) treatments for 0, 1, 3, 6, 12, or 24 h, respectively. The relative expression levels were determined using qRT-PCR. The expression levels of the appropriate controls were set to a value of 1. Three biological replicates were analyzed for each of the indicated lines. Each replicate was composed of leaves of three seedlings. The bars indicate the mean values. The error bars indicate the SEs. The asterisks indicate statistically significant differences relative to the appropriate control according to Student’s t test (*P < 0.05; **P < 0.01)
