Expression profiles of transcription factor-encoding genes and hormone-related genes during key stages of Arabica SE. The x-axis corresponds to the different developmental stages and the y-axis to the number of normalized counts for each gene after RNA-seq read mapping on the Arabica reference genome followed by DESEq2 normalization. A SERK1, SERK2, CLV3, BBM, ABI3, LEC1, AGL15, WOX2, WUS and FUS3 were studied. Genes were classified in 4 types of expression profiles (I, II, III, IV). Class III was subdivided into 2 subclasses (a & b) corresponding to high and low gene expression, respectively. B Auxin-related genes (IAA29, TAA1 and YUCCA4), cytokinin-related genes (ARR10, ARR14), ABA-related genes (PYR1, ABI5) and ethylene-related genes (ERF022, ACS7) were investigated. The colored area corresponds to total exogenous auxin removal from the medium
