Fossil record of the Icacinaceae and its paleogeographic implications [PDF]
Review of Palaeobotany and Palynology, 2020 Abstract In the past decades, the concept of Icacinaceae has been refined greatly, as morphological and molecular data have led to a narrower circumscription of a monophyletic Icacinaceae family with only 23 genera (vs 58 sensu Sleumer, 1942 ). This family possesses an extensive fossil record, important to the biogeographic history of the Northern ...

The family classification of the New Caledonian angiosperms has become more stable with the application of the APG system. [PDF]
CladisticsAbstract The era of molecular systematics has had a tremendous impact on taxonomy, with the increasing availability of phylogenetic trees allowing the recircumscription of higher taxa, particularly through the application of the monophyletic principle.

Climate adaptation and functional constraints drive pollen evolution in Apiales. [PDF]
New PhytolSummary Pollen grains exhibit remarkable morphological diversity, shaped by selective pressures from environmental factors and mechanical constraints. Here, we investigate macroevolutionary patterns of pollen morphology in Apiales, an order of angiosperms with significant ecological and geographical diversity, to disentangle the roles of climate and ...

The stepwise rise of angiosperm-dominated terrestrial ecosystems. [PDF]
Biol Rev Camb Philos SocABSTRACT Angiosperms are the most diverse and abundant plant taxon today and dominate the majority of Earth's terrestrial ecosystems. They underwent rapid divergence and biogeographic expansion from the early to the middle Cretaceous. Yet, transformative ecosystem change brought about by the increased ecological dominance of angiosperms unfolded ...

Chromosome-level genome assembly of Iodes seguinii and its metabonomic implications for rheumatoid arthritis treatment. [PDF]
Plant GenomeAbstract Iodes seguinii is a woody vine known for its potential therapeutic applications in treating rheumatoid arthritis (RA) due to its rich bioactive components. Here, we achieved the first chromosome‐level assembly of the nuclear genome of I. seguinii using PacBio HiFi and chromatin conformation capture (Hi‐C) sequencing data.

Applications in Plant Sciences, Volume 11, Issue 5, September-October 2023., 2023 Abstract Premise Quantitative plant traits play a crucial role in biological research. However, traditional methods for measuring plant morphology are time consuming and have limited scalability. We present LeafMachine2, a suite of modular machine learning and computer vision tools that can automatically extract a base set of leaf traits from digital ...

Diversification of the stem vascular system in a clade of recent radiation and multiple habit transitions: The Bunchosia clade (Malpighiaceae). [PDF]
Am J BotAbstract Premise Within the Malpighiaceae, the Bunchosia clade is distinctive for its significant habit variation and abundance of different vascular variants. However, the processes underlying the diversification of the vascular system over time and the ontogenetic events involved remain unclear.

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.
