"Cattleya iricolor" grows in Peru and Ecuador in montane forests of the eastern Andes
ABC model of flower development "Arabidopsis", where they are also involved in controlling the development of carpels and the ovule and even with structures related to seed dispersal. The appearance of interesting phenotypes in RNA interference studies in "Petunia" and tomato led, in 1994, to the definition of a new type of function in the floral development model. The E function was initially thought to be only involved in the development of the three innermost verticils, however, subsequent work found that its expression was required in all the floral verticils.
