Synorganisation without organ fusion in the flowers of Geranium robertianum (Geraniaceae) and its not so trivial obdiplostemony [PDF]

open access: yes, 2017
Background and Aims Synorganisation of floral organs, an important means in angiosperm flower evolution, is mostly realized by congenital or post-genital organ fusion.

Nuclear phylogenomics of angiosperms and insights into their relationships and evolution

open access: yesJournal of Integrative Plant Biology, Volume 66, Issue 3, Page 546-578, March 2024.
This review synthesizes numerous nuclear phylogenomic analyses of angiosperms (analyses that resolved the relationships of major clades, most orders, and many families and subgroups) and discusses the improved understanding of angiosperm biogeography, diversification dynamics, and character evolution.

Floral structure and systematics in four orders of rosids, including a broad survey of floral mucilage cells [PDF]

open access: yes, 2018
Phylogenetic studies have greatly impacted upon the circumscription of taxa within the rosid clade, resulting in novel relationships at all systematic levels. In many cases the floral structure of these taxa has never been compared, and in some families,

A new remarkable Early Cretaceous nelumbonaceous fossil bridges the gap between herbaceous aquatic and woody protealeans [PDF]

open access: yes, 2023
Dating back to the late Early Cretaceous, the macrofossil record of the iconic lotus family (Nelumbonaceae) is one of the oldest of flowering plants and suggests that their unmistakable leaves and nutlets embedded in large pitted receptacular fruits ...

Angiosperm‐wide analysis of fruit and ovary evolution aided by a new nuclear phylogeny supports association of the same ovary type with both dry and fleshy fruits

open access: yesJournal of Integrative Plant Biology, Volume 66, Issue 2, Page 228-251, February 2024.
Phylogenetic analysis and molecular dating elucidate relationships for orders and families, trace crown angiosperms’ Triassic origin, unveil parallel carpel fusions in early eudicots, monocots, and magnoliids and associate specific fruit types sharing the same ovary type.

The Immense Diversity of Floral Monosymmetry and Asymmetry Across Angiosperms [PDF]

open access: yes, 2018
Floral monosymmetry and asymmetry are traced through the angiosperm orders and families. Both are diverse and widespread in angiosperms. The systematic distribution of the different forms of monosymmetry and asymmetry indicates that both evolved numerous

Angiosperm phylogeny inferred from sequences of four mitochondrial genes [PDF]

open access: yes, 2010
An angiosperm phylogeny was reconstructed in a maximum likelihood analysis of sequences of four mitochondrial genes, atp1, matR, nad5 , and rps3 , from 380 species that represent 376 genera and 296 families of seed plants.

PLANiTS: a curated sequence reference dataset for plant ITS DNA metabarcoding [PDF]

open access: yes, 2020
DNA metabarcoding combines DNA barcoding with high-throughput sequencing to identify different taxa within environmental communities. The ITS has already been proposed and widely used as universal barcode marker for plants, but a comprehensive, updated ...

A Rosid Is a Rosid Is a Rosid . . . or Not [PDF]

open access: yes, 2013
The current structure of 583 Magnoliopsida (Dicotyledons) and 584 Liliopsida (Monocotyledons) in the Dewey Decimal Classification (DDC) system reflects changes made when the life sciences were thoroughly revised in 1996.

First steps towards a floral structural characterization of the major rosid subclades [PDF]

open access: yes, 2018
A survey of our own comparative studies on several larger clades of rosids and over 1400 original publications on rosid flowers shows that floral structural features support to various degrees the supraordinal relationships in rosids proposed by ...
