Deciphering the biosynthetic pathways of lichen acids

open access: yesNew Phytologist, Volume 250, Issue 3, Page 1784-1799, May 2026.
Summary Depsides and depsidones are polyketide‐derived lichen acids widely distributed in lichen thalli, yet the biosynthetic gene clusters (BGCs) responsible for their production remain poorly understood. To address this gap, we investigated the diversity and evolutionary relationships of polyketide BGCs in lichens.

The Unruh effect without thermality

open access: yes, 2018
We show that uniformly accelerated detectors can display genuinely thermal features even if the Kubo-Martin-Schwinger (KMS) condition fails to hold. These features include satisfying thermal detailed balance and having a Planckian response identical to ...

School starters’ early structure sense [PDF]

open access: yes, 2012
Low and high achieving children’s competences regarding pattern and structure at the beginning of formal schooling are comparatively analyzed in order to evaluate the range of school starters’ early structure sense.

Nonlinear 3-D inversion of gravity data over a sulfide ore body

open access: yesGeofísica Internacional, 2000
El gradiente gravimétrico horizontal y el principio de superposición de campos potenciales son utilizados en la interpretación de los datos gravimétricos de un yacimiento de sulfuros mediante una estructura 3-D de densidades.

The Arabidopsis NPF7.2 mediates coumarin uptake for root iron acquisition

open access: yesNew Phytologist, Volume 250, Issue 3, Page 1619-1633, May 2026.
Summary Iron (Fe) is a transition metal necessary for achieving essential physiological processes throughout the plant lifecycle. In Arabidopsis thaliana, secreting Fe‐mobilizing coumarins (FMC) is a key mechanism enabling roots to acquire nonbioavailable Fe present in soils.

Efficient preliminary floating offshore wind turbine design and testing methodologies and application to a concrete spar design [PDF]

open access: yes, 2015
The current key challenge in the floating offshore wind turbine industry and research is on designing economic floating systems that can compete with fixed-bottom offshore turbines in terms of levelized cost of energy. The preliminary platform design, as

Análisis estructural de un bosque natural localizado en zona rural del municipio de Popayán

open access: yesBiotecnología en el Sector Agropecuario y Agroindustrial, 2009
Las características estructurales de un bosque natural son un aspecto muy importante para conocer su dinámica y especialmente para definir su estructura y composición, lo que permitirá diseñar un plan de manejo dependiendo de los resultados obtenidos.

Antisense reduction in NADP‐ME in the C4 species Flaveria bidentis alters stomatal sensitivity to intercellular [CO2]

open access: yesNew Phytologist, Volume 250, Issue 3, Page 1585-1597, May 2026.
Summary Stomata have the crucial role of balancing the uptake of CO2 for photosynthesis and water loss via transpiration by adjusting their aperture. In C3 plants, coordination between photosynthesis and stomatal conductance can be disrupted by mutations in Calvin–Benson–Bassham (CBB) cycle expression, but it is not clear whether the disruption of the ...
