Expression evaluation of the identified PpNAC and stress related genes under different abiotic stresses in P. pyrifolia ‘Suli’. a, b qRT-PCR was used to examine the expression patterns of subgroups 2D and 3D in pear explants under low temperature (4 ^oC), drought (15% PEG 6000) and high salinity (200 mM NaCl) stresses for 0 h, 1 h, 6 h, 12 h and 48 h represented by black, white, red, blue, green and gray bars in graphs respectively. c, To reconfirm the stress status and NAC relation during abiotic stresses, different stress responsive and COR genes are analyzed in same samples. The data were normalized to the pear ACTIN expression level and the mean expression value was premeditated from 4 independent replicates while the standard deviation are shown by vertical bars
