Identification of a novel link connecting indole‐3‐acetamide with abscisic acid biosynthesis and signaling

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2452-2466, March 2026.
Summary Plants orchestrate their developmental processes and responses to environmental stimuli through a sophisticated network of small signaling molecules, termed phytohormones. Among these, auxins are recognized for their role in promoting plant growth.

Persistencia y cambio de las unidades de producción hortícola en el Cinturón Verde del Gran Rosario

open access: yesMundo Agrario, 2006
The horticulture production units in the Green Belt of Gran Rosario appeared in a space traditionally used to the exportable agricultural production. Presents since the XIXth century in the area, they were growing in function of the demographic growth to

Nutrient addition and herbivore exclusion alter plant traits and biomass via distinct mechanisms: intraspecific variability vs species turnover

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2251-2262, March 2026.
Summary Soil nutrients and vertebrate herbivory are key ecological factors with opposite and interactive effects on grassland plant traits and biomass. Partitioning trait changes into species turnover and intraspecific change provides a mechanistic linkage between trait shifts and biomass responses.

Was the evolution of faster stomata driven by increased gas exchange rates rather than increasing water use efficiency?

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2355-2371, March 2026.
Summary Following changes in light flux, photosynthesis (A) typically adjusts more quickly than stomatal conductance (gs), which is dependent on changes in stomatal aperture. Faster stomatal responses are proposed to reduce water loss and enhance growth in dynamic light environments. Stomatal opening and closing parameters were determined in a range of

Estructura y cambio social

open access: yes, 2015
ABSTRACT: Concept or reality? To respond to this question is difficult. The most approximated than it is possible to be said is that the structures comprise of the reality, although are not material realities as soon as such (but rather " conceptuales").

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

open access: yesNew 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.

Revisiting the relationship between stomatal size and speed across species – a meta‐analysis

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2338-2354, March 2026.
Summary The rate of stomatal opening and closure in response to changes in light affects leaf photosynthesis and water use. However, it is unclear how strongly stomatal size (SS) and density (SD) influence stomatal conductance (gs) kinetics, and whether variation arises from methodological differences, guard cell type or degree of amphistomaty.
