Sequence diversity in the monooxygenases involved in oxime production in plant defense and signaling: a conservative revision in the nomenclature of the highly complex CYP79 family

open access: yesThe Plant Journal, Volume 120, Issue 3, Page 1236-1256, November 2024.
SUMMARY Cytochrome P450 monooxygenases of the CYP79 family catalyze conversion of specific amino acids into oximes feeding into a variety of metabolic plant pathways. Here we present an extensive phylogenetic tree of the CYP79 family built on carefully curated sequences collected across the entire plant kingdom.

Seeing double: two different homospermidine oxidases are involved in pyrrolizidine alkaloid biosynthesis in different organs of comfrey (Symphytum officinale)

open access: yesThe Plant Journal, Volume 119, Issue 3, Page 1272-1288, August 2024.
SUMMARY Pyrrolizidine alkaloids (PAs) are toxic specialized metabolites produced in several plant species and frequently contaminate herbal teas or livestock feed. In comfrey (Symphytum officinale, Boraginaceae), they are produced in two different organs of the plant, the root and young leaves. In this study, we demonstrate that homospermidine oxidase (

The typification of Cordia flavescens Aubl., the transfer of Firensia Scop. from Cordia L. (Cordiaceae; Boraginales) to the synonymy of Ocotea Aubl. (Lauraceae), and the identity of the species of Firensia

open access: yesPhytoKeys, 2013
Firensia Scop. was based on Cordia flavescens Aubl., a species described and illustrated from a mixed collection that Scopoli never transferred to Firensia. The genus included three additional species formally named by Rafinesque.

Mass Taxon-Sampling as a Strategy towards Illuminating the Natural History of Campanula (Campanuloideae) [PDF]

open access: yes, 2012
Speciose clades usually harbor species with a broad spectrum of adaptive strategies and complex distribution patterns, and thus constitute ideal systems to disentangle biotic and abiotic causes underlying species diversification. The delimitation of such

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.

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.

A New Species of Cordia (Cordiaceae, Boraginales) from Brazil

open access: yesNovon: A Journal for Botanical Nomenclature, 2010
A new species from Brazil, Cordia pilosa M. Stapf & Taroda (Cordiaceae), is described from northeastern Brazil. Illustrations and data on habitat, distribution, and phenology are provided. The new species belongs to Cordia sect. Superbiflorae Taroda, and it is distinguished from similar species in section Superbiflorae by its compact inflorescences and

A revision of Cordiaceae (Boraginales) in Central America, Mexico, and the United States

open access: yesJournal of the Botanical Research Institute of Texas, 2023
A taxonomic revision is provided for Cordiaceae (Boraginales) in Mexico and Central America and the adjacent portions of the United States, including 44 species of Cordia and 17 species of Varronia. Eight of the 44 species of Cordia were described as new to science elsewhere in earlier parts of this study.
