Vast, overlooked peat, and organic soils in Brazil's Cerrado: carbon storage, dynamics, and stability

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2946-2965, June 2026.
Summary Tropical peatlands are critical for climate mitigation due to their dual role as major carbon sinks and methane sources. In rainforests, high and stable rainfall supports peat accumulation in tropical climates. However, groundwater‐fed peatlands in seasonally dry tropical ecosystems remain poorly understood, despite their potential importance ...

An eco‐evolutionary optimality model explains the acclimated temperature response of photosynthesis

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2884-2899, June 2026.
Summary The optimal temperature of photosynthesis (Topt) generally increases with plant growth temperature. Changes in Topt are associated with changes in the maximum carboxylation capacity at 25°C (Vcmax25) and the maximum electron transport rate at 25°C (Jmax25). The ratio between Jmax25 and Vcmax25 declines with warming.

Da Vinci's mischief: xylem conduits in the stems of woody plants do not furcate

open access: yesNew Phytologist, Volume 250, Issue 5, Page 3001-3013, June 2026.
Summary The hydraulic architecture of plants is often modeled as a ‘furcating’ network, in which xylem conduits proliferate in number toward the stem apex, analogous to animal circulatory systems. Yet whether furcation actually occurs within woody stems remains untested, despite major implications for carbon costs and hydraulic efficiency.

Atmospheric dust is a global nutrient source for plants via foliar uptake

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2867-2883, June 2026.
Summary Atmospheric mineral dust is a critical nutrient supplier to marine ecosystems, but its role in terrestrial plant nutrition remains underexplored due to the assumption that nutrients are acquired solely from soils via roots. Here, we demonstrate that plants directly acquire nutrients from dust through leaves, revealing an unrecognized ...

Estructura florística de especies forestales de un sector del Arboretum Forestal del Centro de Investigación y Enseñanza Forestal “Puerto Almendra” – Loreto – Perú

open access: yes, 2020
O principal objetivo do estudo foi avaliar a estrutura florística de espécies florestais em um setor de floresta tropical, referente à abundância, frequência, dominância, índice de valor de importância (IVI); índice de reflorestamento, (IR); complexidade florística, (CF); estrutura horizontal (EH) e estrutura vertical (EV) de um grupo de espécies ...

Retención variable en bosques de Nothofagus pumilio (Poepp. & Endl.) Krasser en Patagonia sur: estructura forestal, estabilidad estructural y regeneración

open access: yes, 2013
Nothofagus pumilio forests are managed by shelterwood cuts and thinning, producing impacts on the original forest, transforming the primary forest on managed secondary forests with high timber productivity. The aim of this work is to analyze the management schemes, and propose an alternative that improves conservation taking into account current ...

Bioconversion of carotenoids into high‐value crocins using a marine sponge carotenoid cleavage dioxygenase

open access: yesNew Phytologist, Volume 250, Issue 5, Page 3230-3246, June 2026.
Summary Carotenoids and apocarotenoids are widespread specialized metabolites, yet animals, including sponges, lack the ability to synthesize carotenoids de novo and must obtain them from dietary or microbial sources. The roles of carotenoid cleavage dioxygenases (CCDs) in marine animals remain largely unexplored. A CCD from the marine sponge Suberites

Constitutive and inducible oleoresin defenses share genetic architectures and mechanisms in Pinus taeda

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2966-2987, June 2026.
Summary The oleoresin defense system of loblolly pine (Pinus taeda) protects trees from insects and pathogens and is an important source of renewable biofuels and chemicals, but the genetic basis of oleoresin production is poorly understood. We characterized the genetic architecture of oleoresin flow, resin canal number, stem wood terpene content, and ...
