Comparative transcriptome analysis mining the candidate gene AaBEE1. a Two different color-type A. arguta cultivars, ‘ZHB’ and ‘ZLB’, at three development stages were used for transcriptome analysis. The solid arrows indicate comparisons between two samples. b Venn diagram of the six different comparisons used for gene screening. c Transient overexpression of the candidate gene AaBEE1 in the red-background tobacco. d Subcellular localization of AaBEE1 in Arabidopsis thaliana protoplasts. Scale bar: 10 μm
