Expression patterns of PbrGG genes under abiotic stress. The relative expression levels of PbrGG genes were analyzed by qRT-PCR, and the samples were harvested from roots after N-deficiency treatment for five days; and the samples were harvested from leaves after ABA treatment for 6 h. For each gene, the relative expression levels were acquired by normalization to that of pear Actin. The error bars indicate standard deviations. Asterisks indicate a significant difference (*P < 0.05) compared with CK after abiotic stress treatment. Data are expressed as mean ± standard deviation
