A flower's anatomy, as defined by the presence of a series of organs (sepals, petals, stamens and carpels) positioned according to a given pattern, facilitate sexual reproduction in flowering plants. The flower arises from the activity of three classes of genes, which regulate floral development: • Meristem identity genes, which code for the transcription factors required to ini… WebJul 1, 2001 · The inflorescence of Arabidopsis consists of a continuum of siliques at different stages of development. As such, the most mature siliques shatter to release …

WebThe early development of the flower of Arabidopsis thaliana is described from initiation until the opening of the bud. The morphogenesis, growth rate, and surface structure of floral organs were recorded in detail using scanning electron microscopy. Flower development has been divided into 12 stages using a series of landmark events. WebOct 12, 2010 · A huge variation in floral morphology exists among eudicots and between eudicots and monocots. Arabidopsis has become a model for flower development due to its stereotypical floral ontogeny, with four sepals, four petals, usually six stamens comprised of four medial and two lateral, and a gynoecium consisting of two fused carpels, in … imss hamburgo 289
