Dinàmica orientacional i estructura local en liquids moleculars sobrerefredats

, 2023
The aim of this thesis is to study, by means of molecular dynamics simulations, the behaviour of two molecular models at different temperatures, approaching the glass transition. One of them mimics methanol molecules, whereas the other differs from the former only in the ability of forming hydrogen bonds.

Climate adaptation and functional constraints drive pollen evolution in Apiales

New Phytologist, Volume 249, Issue 5, Page 2574-2587, March 2026.
Summary 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 Water Vapor Abundance in Orion KL Outflows [PDF]

, 2006
We present the detection and modeling of more than 70 far-IR pure rotational lines of water vapor, including the 18O and 17O isotopologues, towards Orion KL.

Biogeography and host associations of Russula subsection Xerampelinae based on large‐scale analysis of UNITE sequence data

New Phytologist, Volume 249, Issue 5, Page 2547-2558, March 2026.
Summary Estimating fungal geographic ranges and niche potential is limited by the ephemeral nature of fruiting bodies. While environmental DNA offers broader insights, species‐level identification remains difficult due to uncertain sequence clustering thresholds, low interspecific variation in barcoding regions, and limited taxonomic resolution.

Transcriptomic prey‐capture responses in convergently evolved carnivorous pitcher plants

New Phytologist, Volume 249, Issue 5, Page 2559-2573, March 2026.
Summary The Australian pitcher plant Cephalotus and the Asian pitcher plant Nepenthes exhibit striking morphological and functional similarities, serving as compelling examples of convergent evolution. Although trapping pitchers in both lineages represent some of the most elaborate leaf structures in angiosperms, it remains unknown whether their ...

Understanding the dynamic nature of plant lipid anabolic and catabolic metabolism is key to sustainable oilseed engineering

New Phytologist, Volume 249, Issue 5, Page 2196-2214, March 2026.
Summary Plant‐derived oils are essential sources of reduced carbon and various fatty acid (FA) structures for food, biofuels, and the oleochemical industry. Despite extensive efforts, engineering mainstream oilseed crops to produce high levels of industrially valuable unusual FAs (UFAs) remains challenging.

Mechanism of Molecular Orientation by Single-cycle Pulses

, 2012
Significant molecular orientation can be achieved by time-symmetric single-cycle pulses of zero area, in the THz region. We show that in spite of the existence of a combined time-space symmetry operation, not only large peak instantaneous orientations ...

Leaf litter and fine roots have distinct effects on particulate and mineral‐associated soil organic matter in a tree common garden

New Phytologist, Volume 249, Issue 5, Page 2263-2272, March 2026.
Summary Soil organic matter (SOM) is primarily derived from leaf and root inputs, but the relative contributions of each are difficult to study without the use of isotopic tracers. Furthermore, associations between trees and mycorrhizal fungi can influence the production and persistence of SOM.
