Physical constraints and environmental factors shape phloem anatomical traits in woody angiosperm species

New Phytologist, Volume 248, Issue 5, Page 2316-2330, December 2025.
Summary Xylem trait studies have enhanced our understanding of how plants strategically adapt their morphological and anatomical features to diverse climates. Despite the importance of the phloem in plant functioning, similar studies of phloem traits are lacking.

An Iterative Approach for the Optimization of Pavement Maintenance Management at the Network Level

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
Pavement maintenance is one of the major issues of public agencies. Insufficient investment or inefficient maintenance strategies lead to high economic expenses in the long term. Under budgetary restrictions, the optimal allocation of resources becomes a crucial aspect.

Apocynaceae wood evolution matches key morphological innovations

American Journal of Botany, Volume 111, Issue 11, November 2024.
Abstract Premise This paper provides an overview of the wood anatomy of the dogbane family (Apocynaceae), reconstructs wood anatomical trait evolution, and links this evolution with woody growth‐form transitions and floral and seed trait innovations across the family.

Acción del agua y la temperatura ambiental extrema sobre pavimento flexible

GnosisWisdom, 2021
Para el diseño de pavimentos flexibles se han incluido variables climáticas, pues se ha demostrado que es un factor que incide en el comportamiento estructural de las carreteras; siendo necesario incluir el efecto climático en el diseño de estructuras de pavimentos; en este sentido, el objetivo de esta investigación bibliográfica es mostrar que el ...

Chloroplast NADH dehydrogenase‐like complex‐mediated cyclic electron flow is the main electron transport route in C4 bundle sheath cells

New Phytologist, Volume 243, Issue 6, Page 2187-2200, September 2024.
Summary The superior productivity of C4 plants is achieved via a metabolic C4 cycle which acts as a CO2 pump across mesophyll and bundle sheath (BS) cells and requires an additional input of energy in the form of ATP. The importance of chloroplast NADH dehydrogenase‐like complex (NDH) operating cyclic electron flow (CEF) around Photosystem I (PSI) for ...

Decoupling cell size homeostasis in diatoms from the geometrical constraints of the silica cell wall

New Phytologist, Volume 243, Issue 1, Page 258-270, July 2024.
Summary Unicellular organisms are known to exert tight control over their cell size. In the case of diatoms, abundant eukaryotic microalgae, two opposing notions are widely accepted. On the one hand, the rigid silica cell wall that forms inside the parental cell is thought to enforce geometrical reduction of the cell size.

How and why do species break a developmental trade‐off? Elucidating the association of trichomes and stomata across species

American Journal of Botany, Volume 111, Issue 5, May 2024.
Abstract Premise Previous studies have suggested a trade‐off between trichome density (Dt) and stomatal density (Ds) due to shared cell precursors. We clarified how, when, and why this developmental trade‐off may be overcome across species. Methods We derived equations to determine the developmental basis for Dt and Ds in trichome and stomatal indices (
