The evolutionary fate of rpl32 and rps16 losses in the Euphorbia schimperi (Euphorbiaceae) plastome

open access: yesScientific Reports, 2021
Gene transfers from mitochondria and plastids to the nucleus are an important process in the evolution of the eukaryotic cell. Plastid (pt) gene losses have been documented in multiple angiosperm lineages and are often associated with functional ...

Non-dispersive phloem-protein bodies (NPBs) of Populus trichocarpa consist of a SEOR protein and do not respond to cell wounding and Ca2+ [PDF]

open access: yesPeerJ, 2018
Differentiating sieve elements in the phloem of angiosperms produce abundant phloem-specific proteins before their protein synthesis machinery is degraded.

Horizontal transfer of expressed genes in a parasitic flowering plant [PDF]

open access: yes, 2014
Background: Recent studies have shown that plant genomes have potentially undergone rampant horizontal gene transfer (HGT). In plant parasitic systems HGT appears to be facilitated by the intimate physical association between the parasite and its host ...

Structure and development of flowers and inflorescences in Peraceae and Euphorbiaceae and the evolution of pseudanthia in Malpighiales. [PDF]

open access: yesPLoS ONE, 2018
Pseudanthia are reduced and compact inflorescences which apparently had independent evolution in Euphorbiaceae and Peraceae within Malpighiales. In order to analyze the hypothesis that the different pseudanthia found in Malpighiales have non-homologous ...

Floral anatomy points to autogamy as the evolutionary path in Elatinaceae (Malpighiales) [PDF]

open access: green, 2022
Abstract Since being established, the phylogenetic position of Elatinaceae has been controversial, but recent phylogenetic studies place it in Malpighiales as the sister group of Malpighiaceae. Molecular data support this relationship, but some morphological aspects of it are still poorly understood, especially floral evolution in Elatinaceae ...

Synopsis of Acalypha L. (Euphorbiaceae) of Peru and Bolivia, with description of a new species

open access: yesAnales del Jardín Botánico de Madrid, 2013
A critical review of the Peruvian and Bolivian species of Acalypha L. (Euphorbiaceae) is presented. As a result 41 species (42 taxa) are accepted, 31 from Peru and 28 from Bolivia, and 94 names are considered synonyms.

Evolution of plant ribosome-inactivating proteins [PDF]

open access: yes, 2010
This contribution presents an updated analysis of the evolution of ribosome-inactivating proteins (RIPs) in plants. All evidence suggests that an ancestor of modern seed plants developed the RIP domain at least 300 million years ago.

A specific case in the classification of woods by FTIR and chemometric: discrimination of Fagales from Malpighiales [PDF]

open access: yes, 2014
Fourier transform infrared (FTIR) spectroscopic data was used to classify wood samples from nine species within the Fagales and Malpighiales using a range of multivariate statistical methods. Taxonomic classification of the family Fagaceae and Betulaceae
