TRIMETHYLGUANOSINE SYNTHASE1 mutations decanalize female germline development in Arabidopsis

New Phytologist, Volume 240, Issue 2, Page 597-612, October 2023., 2023
Summary Here, we report the characterization of a plant RNA methyltransferase, orthologous to yeast trimethylguanosine synthase1 (Tgs1p) and whose downregulation was associated with apomixis in Paspalum grasses. Using phylogenetic analyses and yeast complementation, we determined that land plant genomes all encode a conserved, specific TGS1 protein ...

Native palms and trees mediate drought impacts on dry neotropical pastures

Journal of Applied Ecology, Volume 60, Issue 7, Page 1376-1387, July 2023., 2023
Abstract Dry forests are the most threatened biome across the global tropics. Despite their massive conversion into agricultural landscapes, local farmers often retain disperse trees and palms within grazing pastures. Understanding how on‐farm tree cover in the dry neotropics impacts the environmental and productive functions of pastures is key for ...

From the ground up: Patterns and perceptions of herbaceous diversity in organic coffee agroecosystems

Ecological Solutions and Evidence, Volume 3, Issue 3, July–September 2022., 2022
Smallholder farms that transition to organic and biodiverse production are increasingly recognized as strongholds of agrobiodiversity. Yet the emergent herbaceous communities in these organic systems remain understudied, with the functional diversity and management of this stratum relatively unknown.

Cuerpos de cobre: Extractivismo en Chuquicamata, Chile

The Journal of Latin American and Caribbean Anthropology, Volume 26, Issue 2, Page 200-218, June 2021., 2021
Resumen ¿Qué extraen y qué producen los extractivismos? El presente artículo intenta responder a esta pregunta analizando críticamente, la relación entre cuerpos, trabajo y mi‐nería principalmente bajo el modelo neoliberal chileno, en la mina estatal de cobre a tajo abierto más grande del planeta: Chuquicamata.

A Narrative Walks Into a Forum: Bridging the Narrative Policy and Ecology of Games Frameworks

Policy Studies Journal, Volume 54, Issue 3, August 2026.
ABSTRACT Policy process research has expanded rapidly, yet many frameworks still develop in silos, limiting dialogue and leaving complementary mechanisms underused. In an effort to bridge these silos, we bring together two influential frameworks that have largely developed in parallel: the Narrative Policy Framework (NPF) and the Ecology of Games ...

Phosphate starvation induces root cell‐type‐specific transcriptional responses and alternative splicing

New Phytologist, Volume 250, Issue 5, Page 3212-3229, June 2026.
Summary Phosphate (Pi) is an essential nutrient for plant growth, and understanding how Arabidopsis thaliana root cells respond to Pi deficiency is crucial to decipher whole plant responses. We perform high‐resolution transcriptomic profiling across five distinct root cell types, identifying differentially expressed genes (DEGs) and differential ...
