Pollen aperture evolution--a crucial factor for eudicot success?
Carol A. Furness,Paula J. Rudall +1 more
TLDR
Increased aperture number in angiosperm pollen grains offers a potential selective advantage because it increases the number of prospective germination sites, thus facilitating contact between at least one aperture and the stigmatic surface.About:

Testing the Impact of Calibration on Molecular Divergence Times Using a Fossil-Rich Group: The Case of Nothofagus (Fagales)
Hervé Sauquet,Simon Y. W. Ho,Simon Y. W. Ho,Maria A. Gandolfo,Gregory J. Jordan,Peter Wilf,David J. Cantrill,Michael J. Bayly,Lindell Bromham,Gillian K. Brown,Gillian K. Brown,Raymond J. Carpenter,Daphne M. Lee,Daniel J. Murphy,J. M. Kale Sniderman,Frank Udovicic +15 more
TL;DR: It is suggested that increased background research should be made at all stages of the calibration process to reduce errors wherever possible, from verifying the geochronological data on the fossils to critical reassessment of their phylogenetic position.
Journal ArticleDOI
Establishing a time-scale for plant evolution
TL;DR: A post-Jurassic origin of angiosperms and a post-Cambrian origin of land plants are rejected, and it is suggested that the establishment of the major embryophyte lineages occurred at a much slower tempo than suggested in most previous studies.

Toward a predictive understanding of the fitness costs of heterospecific pollen receipt and its importance in co-flowering communities
TL;DR: A conceptual framework for understanding variation in fitness consequences of HP receipt is developed and can guide much needed additional work so that it can evaluate whether and which plant traits contribute to the variation in the effects of HP receipts.
Journal ArticleDOI
Morphological and molecular phylogenetic context of the angiosperms: contrasting the ‘top-down’ and ‘bottom-up’ approaches used to infer the likely characteristics of the first flowers
TL;DR: This work advocates maintenance of parallel, reciprocally illuminating programmes of morphological and molecular phylogeny reconstruction, respectively supported by homology testing through additional taxa and evolutionary-developmental genetic studies that explore genes potentially responsible for major phenotypic transitions.

Phylogenetics of seed plants: an analysis of nucleotide sequences from the plastid gene rbcL.
TL;DR: Two exploratory parsimony analyses of DNA sequences from 475 and 499 species of seed plants, respectively, representing all major taxonomic groups indicate that rbcL sequence variation contains historical evidence appropriate for phylogenetic analysis at this taxonomic level of sampling.
Journal ArticleDOI
Pollen Morphology and Plant Taxonomy
TL;DR: In this article, Pollen Morphology and Plant Taxonomy is discussed. But the focus is on plant taxonomy, and not on pollen morphology and taxonomy of plants.

TL;DR: Recent cladistic analyses are revealing the phylogeny of flowering plants in increasing detail, and there is support for the monophyly of many major groups above the family level.

Angiosperm phylogeny inferred from multiple genes as a tool for comparative biology
TL;DR: The results of parsimony analyses of DNA sequences of the plastid genes rbcL and atpB and the nuclear 18S rDNA for 560 species of angiosperms and seven non-flowering seed plants are reported and show a well-resolved and well-supported phylogenetic tree for the angios perms for use in comparative biology.
