Studies of Angiosperm Phylogeny using Protein Sequences

In previous papers we have reported the N-terminal 40 amino acids of the small subunit of rubisco for samples from four families of gymnosperms, nine families of monocotyledons, and 26 families of dicotyledons.We expanded this list to 122 families of dicots and derived a phylogenetic tree for all 335 species.The main computing program used was HENNIG86, with which a reliable result can be assured with only 17 subsequent testing using the longer sequences from nucleic acids.u species, the nature of the N-terminus of rubisco-SSU, and evidence that natural selection is powerful taxa or less, so a major part of this Topics discussed include amino acid sequence.The rate of evolution has been shown to vary between major taxa, and data suggest that angiosperms originated in the Jurassic.
