Cluster 1 included genes with the highest expression in floral tissue (Figure 4b). Among genes in this cluster several are of interest. For example, this cluster includes many genes defining floral organ identity such as floral homeotic protein AGAMOUS, APETALA 2, PMADS 2 and DEFICIENS. In addition, Cluster 1 also included chromatin structure‐remodelling complex protein SYD, MADS‐box protein CMB1 and many chloroplast and carotenoid genes. Leaf‐enriched Cluster 2 included transcripts‐encoding enzymes involved in photosynthesis, Rubisco and oxygenase activity in addition to many chloroplast and plastid‐regulating genes. Cluster 3 contained genes with high expression in stem and peduncle tissue, and included genes/transcripts‐encoding enzymes involved in nutrient transport, structural growth with a high activity of various receptor kinases, expansins and transferases. Developing seed‐enriched Cluster 4 showed genes genes/transcripts involved with embryogenesis and growth. Cluster 5 enriched with root tissue gene expression profiles included different nodulins, binding proteins, MYB‐transcription factors and both stress‐ and defence‐related genes.
