Expression patterns of B. distachyon ARF genes under various abiotic stresses. The expression profiles of nine representative B. distachyon ARF genes under various abiotic stresses, including IAA, ABA, SA, Cr3+, Zn2+, NaCl, PEG and Hot (42 °C). IAA, indole-3-acetic acid; ABA, abscisic acid; SA, salicylic acid; PEG, polyethylene glycol. The leaf and root are separately analyzed, red color bar presents leaf, sky blue color bar presents root. Statistically significant differences between control group and treatment group were calculated by an independent Student’s t-tests: *p < 0.05, **p < 0.01. 9 BdARFs are sorted according to their clade (Clade Ia: BdARF6, BdARF8, BdARF10; Clade Ib: BdARF2, BdARF4; Clade II: BdARF12, BdARF15; Clade III: BdARF17, BdARF18). And the ordinate represents the expression level, and the abscissa shows different tissues and organs
