Rapid diversification rates in Amazonian Chrysobalanaceae inferred from plastid genome phylogenetics
We studied the evolutionary history of Chrysobalanaceae with phylogenetic analyses of complete plastid genomes from 156 species to assess the tempo of diversification in the Neotropics and help to unravel the causes of Amazonian plant diversification. These plastid genomes had a mean length of 162 204 base pairs, and the...Chave, Jerome ; Sothers, Cynthia ; Iribar, Amaia ; Suescun, Uxue ; Chase, Mark W …

Identifying and mapping individual plants in a highly diverse high-elevation ecosystem using UAV imagery and deep learning
The identification and counting of plant individuals is essential for environmental monitoring. UAV based imagery offer ultra-fine spatial resolution and flexibility in data acquisition, and so provide a great opportunity to enhance current plant and in-situ field surveying. However, accurate mapping of individual plants from UAV imagery remains challenging, given...Zhang, Ce ; Atkinson, Peter M. ; George, Charles ; Wen, Zhaofei ; Diazgranados, Mauricio …

Habitat specialisation controls ectomycorrhizal fungi above the treeline in the European Alps
Alpine habitats are one of the most vulnerable ecosystems to environmental change, however, little information is known about the drivers of plant–fungal interactions in these ecosystems and their resilience to climate change. We investigated the influence of the main drivers of ectomycorrhizal (EM) fungal communities along elevation and environmental gradients... -

A robust phylogenomic framework for the calamoid palms
Well-supported phylogenies are a prerequisite for the study of the evolution and diversity of life on earth. The subfamily Calamoideae accounts for more than one fifth of the palm family (Arecaceae), occurs in tropical rainforests across the world, and supports a billion-dollar industry in rattan products. It contains ca. 550...Kuhnhäuser, Benedikt G. ; Bellot, Sidonie ; Couvreur, Thomas L.P. ; Dransfield, John ; Henderson, Andrew …

Fossil data support a pre-Cretaceous origin of flowering plants
Flowering plants (angiosperms) are the most diverse of all land plants, becoming abundant in the Cretaceous and achieving dominance in the Cenozoic. However, the exact timing of their origin remains a controversial topic, with molecular clocks generally placing their origin much further back in time than the oldest unequivocal fossils....Silvestro, Daniele ; Bacon, Christine D. ; Ding, Wenna ; Zhang, Qiuyue ; Donoghue, Philip C.

Stomatal responses to carbon dioxide and light require abscisic acid catabolism in Arabidopsis
In plants, stomata control water loss and CO2 uptake. The aperture and density of stomatal pores, and hence the exchange of gases between the plant and the atmosphere, are controlled by internal factors such as the plant hormone abscisic acid (ABA) and external signals including light and CO2. In this...Movahedi, Mahsa ; Zoulias, Nicholas ; Casson, Stuart A. ; Sun, Peng ; Liang, Yun-Kuan …
