Fig. 3: Expression patterns of rose MIKC^C genes in different tissues.

a Heatmap of the expression patterns of rose MIKC^C genes. The heatmap was generated using MeV software v. 4.9.0 and is accompanied by a color scale corresponding to the gene expression level (FPKM values) from undetected (0.0) to ≥ 6. The sample names correspond to the previous descriptions⁴³—BFL, closed flower; CYN, rose hip from pollination up to early pigmentation; DBO, active axillary buds (vegetative meristem); DET, stamens at microsporogenesis and microgametogenesis stages; FTB, leaves infected with Botrytis cinerea LR18; FTN, young leaves and stems; FTS, leaves from water-stressed plants; IFL, floral bud at floral meristem transition; IMO, floral meristem and early floral organ (sepals, petals, stamens and carpels) development; NDB, dormant axillary buds (vegetative meristem); OFT, open flower; RAC represents white young roots; and SEN, senescent flower. The black box marks the two most important stages (IFL and IMO) of floral transition. b The percentage of all MIKC^C genes detected in the transcriptome dataset of Dubois et al.⁴³ The percentages were cumulated according to the total number (58) of the MIKC^C genes we identified in our study. The top three clades with a higher percentage of detected genes are highlighted in red
