Fruit development can be viewed as the succession of three main steps consisting fruit initiation, growth and ripening. These processes are orchestrated by different factors, notably successful fertilization flowers, environmental conditions hormones whose action is coordinated a large variety transcription factors. Among factor families, TEOSINTE BRANCHED 1, CYCLOIDEA, PROLIFERATING CELL FACTOR (TCP) family has received little attention in frame biology despite its effects on several developmental modulator hormonal pathways. In this respect, comprehension TCP functions remains an incomplete puzzle that needs to assembled. Building abundance genomic transcriptomic data, review aims at collecting available expression data allow their integration light functional genetic studies reported so far. This reveals Class I genes, already known for involvement cell proliferation growth, display significant levels developing fruit, although clear evidence supporting significance process scarce. The extensive compiled our study provide convincing elements shed specific genes ripening, once these reproductive organs acquire mature size. They also emphasize putative role control biological such metabolism dialogue.
