The divergence between monocots and dicots represents a major event in higher plant evolution, yet the date of its occurrence remains unknown because of the scarcity of relevant fossils. We have estimated this date by reconstructing phylogenetic trees from chloroplast DNA sequences, using two independent approaches: the rate of synonymous nucleotide substitution was calibrated from the divergence of maize, wheat, and rice, whereas the rate of nonsynonymous substitution was calibrated from the… 
Dating the Monocot–Dicot Divergence and the Origin of Core Eudicots Using Whole Chloroplast Genomes
TLDR
It is proposed that monocots branched off from dicots 140–150 Myr ago, at least 50 Myr younger than previous estimates based on the molecular clock hypothesis, and that the core eudicots diverged 100–115 Myr ago (Albian–Aptian of the Cretaceous).
Angiosperm origin and early stages of seed plant evolution deduced from rRNA sequence comparisons
TLDR
The data obtained suggest that the divergence of all the main groups of extant gymnosperms occurred after the branching off of the angiosperm lineage, and that Magnoliales are the most ancient group among dicotyledons and leads to modern Liliaceae.
A late origin of the extant eukaryotic diversity: divergence time estimates using rare genomic changes
TLDR
The inference of a "young LECA" is compatible with the latest of previously estimated dates and has substantial biological implications, including an early divergence of monocot and dicot plants, raising the possibility of plant-insect coevolution.
Molecular phylogenies in angiosperm evolution.
TLDR
Cloned and sequenced cDNAs for the glyceraldehyde-3-phosphate dehydrogenase of glycolysis, gapC, from a bryophyte, a gymnosperm, and three angiosperms and chloroplast and nuclear sequence data taken together suggest that the separation of monocotyledonous and dicotylingonous lineages took place in late Carboniferous times.
Rates of Nucleotide Substitution in Angiosperm Mitochondrial DNA Sequences and Dates of Divergence Between Brassica and Other Angiosperm Lineages
Abstract. We obtained 16 nucleotide sequences (∼1400 bp each) of the first intron of the mitochondrial (mt) gene for NADH subunit 4 (nad4) from 10 species of Brassicaceae. Using these new sequences
ANGIOSPERM DIVERGENCE TIMES: THE EFFECT OF GENES, CODON POSITIONS, AND TIME CONSTRAINTS
TLDR
Although absolute age estimates of angiosperms and angiosperm clades are older than their earliest fossils, the estimated pace of phylogenetic diversification largely agrees with the rapid appearance ofAngiosperm lineages in stratigraphic sequences.
Evaluation of Monocot and Eudicot Divergence Using the Sugarcane Transcriptome1[w]
TLDR
The wide comparative genome analysis presented here provides information on the evolutionary changes that underlie the divergence of monocots and eudicots and led to the identification of several not yet annotated putative genes and possible gene loss events in Arabidopsis.
Evolution of the angiosperms: calibrating the family tree
TLDR
Angiosperm divergence times are estimated using non–parametric rate smoothing and a three–gene dataset covering ca.
THE AGE OF THE ANGIOSPERMS: A MOLECULAR TIMESCALE WITHOUT A CLOCK
TLDR
Results indicate that widely divergent age estimates can result from the different methods, different sources of data, and the inclusion of temporal constraints to topologies, and agree with the hypothesis that the angiosperms may be somewhat older than the fossil record indicates.
Molecular Phylogeny and Evolution of the Plant-Specific Seven-Transmembrane MLO Family
TLDR
A computational analysis of MLO family members based on 31 full-size and 3 partial sequences revealed evidence for concerted evolution of all three cytoplasmic domains with each other and the C-terminal cytopLasmic tail, suggesting interplay of all intracellular domains for MLO function.
