Amborella Trichopoda and Angiosperm

In "Emotional evidence of developmental instability in the evolution of early angiosperms", William E. Friedman discusses the reconstruction of the embryonic pattern of various flowering plants (mainly angiosperm plants). Angiosperms are characterized by recent plants that produce seeds in a closed carpet with closed flowers. It has a plant and flower trait evolved from three major lineages of flowering plants - monocots, eumagnoliids and eudicotyledons.

Recent DNA analysis (molecular phylogeny) showed that Amborella trichopoda found in New Caledonia's Pacific islands is the only species of other flowering plant sister population, and morphological studies Suggest that it has distinctive features. The earliest flowering plant. There is definite evidence of this flower about 140 million years ago, but there is some circumstantial evidence that it took up to 250 million years ago. Plants were used to protect the flowers, while olean chemicals are not flowering plants, but they evolved at that time and were detected in fossil plants including monitored lizards with many features of modern flowering plants. As we found that only stems and thorns hold the details, they themselves, one of the earliest examples of petrification

The family Amborellaceae is considered to be the sister branch of all other life flowering plants. As of March 2012, the whole genome of Amborella trichopoda is still sequenced. By comparing its genome with the genome of all other living flowering plants the most likely characteristics of A. trichopoda ancestry and all other flowering can be calculated. Plant, ancestral flowering plant. At the organ level, the leaves seem to be flower ancestors, or at least some flower organs. When several important genes involved in flower development mutate, leaves-like clusters appear instead of flowers. Thus, at some point in history, developmental processes leading to the formation of leaves must be changed to produce flowers. There may be a holistic and robust framework in which flower diversity is created.
