Expression profiles of chickpea ARF genes. Each measurement is the mean of two independent biological samples. a. Multidimensional scaling plot showing relationships between sample types. Distance between samples indicates similarity. b. Expression levels of ARF genes between leaves and roots. Only those genes showing > 2-fold difference expression are shown. c. Hierarchical clustering of CaARF genes. The heat map was constructed using the log2-transformed expression levels. d. Expression levels of selected ARF across different samples. NRQs are rescaled to the control sample. Control R, control roots; ControlL, control leaves; ASL, ascochyta susceptible leaves; ARL ascochyta resistant leaves; DL, drought leaves; DS, drought stems; SL, salt leaves; SS, salt stems; SR salt roots; CL, cold leaves; CF, cold flowers
