Dual Isotope Analysis Reveals Phylogenetic Patterns and Novel Insights Into Methoxy Group Synthesis of Structural Biomolecules in Leaf and Woody Plant Tissues

open access: yesPlant, Cell &Environment, Volume 48, Issue 12, Page 8483-8501, December 2025.
ABSTRACT Stable carbon and hydrogen isotopes of wood methoxy groups (δ2Hmeth, δ13Cmeth), mainly sourced by structural biomolecules like lignin and pectin, provide important insights into climatic, hydrological and physiological conditions. This study systematically investigated species‐specific δ2Hmeth and δ13Cmeth variations in leaves and woody twigs ...

Pseudogenization of the rhizobium-responsive EXOPOLYSACCHARIDE RECEPTOR in Parasponia is a rare event in nodulating plants

open access: yesBMC Plant Biology, 2022
Background Nodule symbiosis with diazotrophic Frankia or rhizobium occurs in plant species belonging to ten taxonomic lineages within the related orders Fabales, Fagales, Cucurbitales, and Rosales.

Genome duplications, genomic conflict, and rapid phenotypic evolution characterize the Cretaceous radiation of Fagales

open access: yesJournal of Integrative Plant Biology, Volume 67, Issue 11, Page 2929-2944, November 2025.
Fagales show “early burst” model of phenotypic disparification, with morphospace being filled during the early radiation of the Fagales crown and its major families. The elevated levels of phenotypic evolution often correspond to hotspots of gene duplication, whereas species diversification is decoupled from both phenotypic and genomic evolution ...

Expelled by the Antarctic ice: Evolutionary history of the tribe Cunonieae (Cunoniaceae)

open access: yesJournal of Systematics and Evolution, Volume 63, Issue 6, Page 1441-1457, November 2025.
Fossil calibration reveals recent radiations and biogeographical history of the Cunonieae tribe. The most densely sampled phylogeny indicated Antarctica and Patagonia as areas of origin, confirming the reestablishment of Pterophylla and revealing the northward movement of Weinmannia into the tropical Andes.

Non-Target Effects of Transgenic Blight-Resistant American Chestnut (Fagales: Fagaceae) on Insect Herbivores [PDF]

open access: yesEnvironmental Entomology, 2011
American chestnut [Castanea dentata (Marshall) Borkhausen], a canopy dominant species across wide swaths of eastern North America, was reduced to an understory shrub after introduction of the blight fungus [Cryphonectria parasitica (Murrill) Barr] in the early 1900s.

Análisis por técnicas morfológicas y secuenciación de ADN del polen atmosférico de la Comunidad de Madrid: estudios preliminares. Morphological analysis and DNA sequencing of atmospheric pollen in Madrid region: preliminary study [PDF]

open access: yes, 2016
Hasta el momento, el estudio de las partículas biológicas en el aire que respiramos, se ha dirigido, principalmente, al conocimiento y control del polen y esporas, aeroalérgenos cuyo impacto en salud es bien conocido.

Inhibition of rhizobial cheaters by the host Medicago truncatula involves repression of symbiotic functions and induction of defense

open access: yesNew Phytologist, Volume 248, Issue 3, Page 1458-1474, November 2025.
Summary In symbiotic plant–microbe interactions, the host invests considerable amounts of resources in the microbial partner. If the microbe does not reciprocate with a comparable symbiotic benefit, it is regarded as a cheater. The host responds to cheaters with negative feedback mechanisms (sanctions) to prevent fitness deficits resulting from being ...

Intermittent pollen-tube growth in Fagales, especially in alders(Alms sieboldiana)

open access: yesPLANT MORPHOLOGY, 2005
Summary: In Fagales, the ovary is still immature when pollen is delivered to the stigma and the fertilization occurs more than one month after pollination. Developmental study of the pollen-tube growth in the pistil of three species(Casuarina equisetifolia, Alnus sieboldiana and Myrica rubra)in Fagales showed that the pollen tube grows intermittently ...

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,
