Real-time terahertz imaging with a single-pixel detector

2021 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2020
Terahertz (THz) radiation is poised to have an essential role in many imaging applications, from industrial inspections to medical diagnosis. However, commercialization is prevented by impractical and expensive THz instrumentation.

Selection maintains floral color polymorphism in scarlet paintbrush, Castilleja coccinea, reflecting combined ecological factors

American Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise Evolutionary theory predicts polymorphism should be rare; however, intraspecific variation in floral color is common and can be attributed to genetic drift, plasticity, or variable selection. Examining floral color polymorphism both within contact zones and across a species' range can reveal the mechanisms maintaining this variation ...

A multiscale growth atlas of Arabidopsis: linking cell dynamics to organ development

New Phytologist, Volume 249, Issue 1, Page 299-324, January 2026.
Summary Plant development depends on coordinated growth at cellular and organ scales, yet comparative analyses are hindered by inconsistent reporting of growth across studies. We conducted a meta‐analysis of Arabidopsis thaliana growth dynamics, integrating data from 176 studies to create the first multiscale atlas of plant growth.

Mapping the density of giant trees in the Amazon

New Phytologist, Volume 249, Issue 1, Page 152-168, January 2026.
Summary Tall trees (height ≥ 60 m) are keystone elements of tropical forests, strongly influencing biodiversity, carbon storage, and ecosystem resilience. Yet, their density and spatial distribution remain poorly quantified, especially in remote Amazonian regions, limiting our understanding of their ecological roles and contribution to forest–climate ...

A cell‐type‐specific regulon controlling monoterpene indole alkaloid biosynthesis with feedback and feedforward activation loops

New Phytologist, Volume 249, Issue 2, Page 945-960, January 2026.
Summary Monoterpene indole alkaloids (MIA) are a diverse class of plant natural products produced by a subset of lineages within the Asterid clade of eudicots. The diversity of MIAs provides a unique opportunity to study not only the evolution of biosynthetic genes but also their regulation.

Arabidopsis root lipid droplets are hubs for membrane homeostasis under heat stress, and triterpenoid synthesis and storage

New Phytologist, Volume 249, Issue 2, Page 892-916, January 2026.
Summary Plant lipid droplets (LDs) and their associated proteins have numerous subcellular and physiological functions. While considerable progress has been made for LDs in many tissues, the function and composition of LDs in roots remain largely unexplored.
