Phenolic metabolism in Sarcandra glabra is mediated by distinct BAHD hydroxycinnamoyltransferases. [PDF]

Plant J
Significance Statement Four genes and enzymes involved in the formation of hydroxycinnamoyl esters with shikimic, quinic, hydroxyphenyllactic, and benzoic acids as well as amides with hydroxyanthranilic and d‐amino acids were identified in Sarcandra glabra (Chloranthaceae), placed in a sister clade of the magnoliids.

Phenolic compounds in species of the Blechnaceae. [PDF]

Plant Biol (Stuttg)
The occurrence of caffeic acid derivatives in 32 species of Blechnaceae revealed differences in the presence of rosmarinic acid and blechnic acid B, a novel compound in ferns. Abstract Rosmarinic acid and other caffeic and 4‐coumaric acid derivatives are widespread in land plants.

A new vesselless angiosperm stem with a cambial variant from the Upper Cretaceous of Antarctica [PDF]

Acta Palaeontologica Polonica, 2020
We sectioned a permineralized stem preserved in marine calcareous concretions from the Campanian (Upper Cretaceous) of James Ross Island, Antarctic Peninsula using the cellulose-acetate peel technique.

A comprehensive illustrated protocol for clearing, mounting, and imaging leaf venation networks. [PDF]

Appl Plant Sci
Abstract Premise Leaf venation network architecture can provide insights into plant evolution, ecology, and physiology. Venation networks are typically assessed through histological methods, but existing protocols provide limited guidance on processing large or challenging leaves.

Toward a phylogenomic classification of magnoliids. [PDF]

Am J Bot
Abstract Premise Magnoliids are a strongly supported clade of angiosperms. Previous phylogenetic studies based primarily on analyses of a limited number of mostly plastid markers have led to the current classification of magnoliids into four orders and 18 families. However, uncertainty remains regarding the placement of several families.

Sexual systems in the New Zealand angiosperm flora

New Zealand Journal of Botany, Volume 61, Issue 4, Page 201-231, December 2023., 2023
ABSTRACT We present data on sexual systems and associated traits in the New Zealand angiosperm flora and discuss reasons for the anomalously high levels of gender dimorphism in the flora, and the low levels of monoecy in woody species. Along with Hawai'i and New Caledonia, New Zealand has exceptionally high levels of gender dimorphism (19.5% of ...

Osmoxylon-like fossils from early Eocene South America: West Gondwana-Malesia connections in Araliaceae. [PDF]

Am J Bot
Abstract Premise Araliaceae comprise a moderately diverse, predominantly tropical angiosperm family with a limited fossil record. Gondwanan history of Araliaceae is hypothesized in the literature, but no fossils have previously been reported from the former supercontinent.

Meta‐analysis of Red List conservation assessments of Mexican endemic and near endemic tree species shows nearly two thirds of these are threatened

PLANTS, PEOPLE, PLANET, Volume 5, Issue 4, Page 581-599, July 2023., 2023
Mexico's extraordinary tree diversity is threatened by the increasing demand for resources because of the tenfold population growth in the last century. The conservation status of trees, and both urban and rural livelihoods, are also negatively affected by agriculture, mining and tourism.
