Expression profiles of the IbPG006, IbPG034 and IbPG099 under PEG6000-induced drought treatment and NaCl-induced salt treatment. (a) Expression patterns of IbPG006 in response to drought stress in FR. (b) Expression patterns of IbPG006 in response to salt stress in FR. (c) Expression patterns of IbPG034 in response to drought stress in FR. (d) Expression patterns of IbPG034 in response to salt stress in FR. (e) Expression patterns of IbPG099 in response to drought stress in FR. (f) Expression patterns of IbPG099 in response to salt stress in FR. The FR of ‘Xushu18’ was obtained at 0, 3, 12, 24, and 48 h after drought and salt treatment. The mean fold changes of each gene between treated and control FR were used to calculate its relative expression levels. Data are means ± SD of three biological replicates. Means denoted by the same letter do not significantly differ at p < 0.05, as determined by Duncan’s multiple range test
