Expression Patterns of ERF Genes Underlying Abiotic Stresses in Di-Haploid Populus simonii × P. nigra

Figure 1

Expression trends of 176 Populus ERF genes in response to NaCl stress in the leaves by RT-PCR analysis. Relative expression level was log2 transformed: >0: upregulation; =0: no change in regulation; <0: downregulation. (a) Expression patterns of 59 responsive PthERFs; (b) 176 ERF genes distributions: 66.48% were no change in regulation; 6.25% were downregulated; the rest were upregulated in different degrees.
