Fig. 1From: iTRAQ protein profile analysis of sugar beet under salt stress: different coping mechanisms in leaves and rootsPhysiological indices for sugar beet subjected to salt stress. a Control plants; b stressed plants treated with 300 mM NaCl; c chlorophyll; d malondialdehyde; e proline; f root activity. The mean and SD were calculated from three repeats of each group and the bars indicate one standard deviation. The asterisk indicates significant difference between control (CK) and salt-stressed (ST), (*p < 0.05)Back to article page
