Dynamic crystallography reveals early signalling events in ultraviolet photoreceptor UVR8 [PDF]
Nature Plants, 2015 Arabidopsis thaliana UVR8 (AtUVR8) is a long-sought-after photoreceptor that undergoes dimer dissociation in response to UV-B light. Crystallographic and mutational studies have identified two crucial tryptophan residues for UV-B responses in AtUVR8. However, the mechanism of UV-B perception and structural events leading up to dimer dissociation remain

Angewandte Chemie International Edition, Volume 65, Issue 21, 18 May 2026.Time‐resolved native mass spectrometry uncovers the blue‐light‐dependent kinetic mechanism of Arabidopsis CRY1 oligomerization, proceeding sequentially from monomers to dimers and tetramers. ATP promotes assembly, whereas BIC1 actively blocks and disassembles tetramers independent of light, providing mechanistic insight into the regulation of ...

Physiologia Plantarum, Volume 178, Issue 3, May/June 2026.ABSTRACT Plants are frequently exposed to adverse conditions. Priming, also known as acclimation or hardening, induces stress memory and prepares plants for future challenges by activating defense and protective mechanisms. For this reason, priming is an effective means to maintain plant yield in the face of climate change. Memory behind the priming is

Plant Biotechnology Journal, Volume 24, Issue 3, Page 1533-1547, March 2026.ABSTRACT Artemisinin, an antimalarial sesquiterpene lactone, is biosynthesized in glandular trichomes of Artemisia annua. Although numerous transcription factors have been demonstrated to regulate artemisinin biosynthesis, the molecular mechanisms underlying the high expression of artemisinin‐associated biosynthetic enzyme and transcription factor ...

Traceless Regulation of Genetic Circuitry
Advanced Science, Volume 13, Issue 10, 18 February 2026.Energy‐based, as opposed to molecular, control offers unprecedented improvements in key circuit parameters. This review summarizes the fundamentals of such traceless switches, categorizes them by trigger modalities, and compares and contrasts distinct advantages as well as shortcomings of each kind.

Functional Ecology, Volume 40, Issue 2, Page 534-552, February 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Non‐structural carbohydrates (NSC) are critical mediators of plant adaptation to fluctuating light environments. They are tightly coordinated with plant economic strategy, that is, leaf economics spectrum (LES) and root economics spectrum (RES).

Subcellular localisation and functional analysis of UVR8, a UV-B specific signalling component in Arabidopsis [PDF]
, 2008 UV-B is an integral component of the daylight spectrum that regulates plant gene expression and development, but very little is known about how plants perceive UV-B.
