Rhizobacteria‐Induced Systemic Priming Against Fungal Pathogens Involves Hydroxycinnamic Acid Amides

Plant, Cell &Environment, Volume 49, Issue 8, Page 4907-4921, August 2026.
ABSTRACT The rhizosphere, a narrow region of soil surrounding roots, contains diverse microorganisms with a composition that is distinct from the surrounding soil. Some rhizosphere bacteria can trigger a heightened state of immunity in the whole plant, termed Induced Systemic Resistance (ISR).

Light‐Activated Communication Between Synthetic and Living Cells via Photoresponsive Membranes

ChemBioChem, Volume 27, Issue 14, 29 July 2026.
Light‐triggered membrane rupture of SCs enables controlled release of adenosine triphosphate (ATP) and histamine, which activate purinergic and histaminergic signaling in HeLa cells, leading to intracellular Ca2+ mobilization. This biomimetic communication platform provides a simple strategy for engineering remotely controlled chemical signaling ...

Reenvisioning the De Mayo Reaction: A Boron‐Enabled Cycloaddition Approach

Angewandte Chemie, Volume 138, Issue 29, 13 July 2026.
An oxa‐boracycle conformational lock strategy enables photocatalytic [2+2] cycloaddition to afford densely substituted cyclobutylboronates. The conformational constraint suppresses triplet relaxation and promotes productive bimolecular reactivity.

Toward Chromoselective Transformations in Biological Systems: Perspectives and Challenges

Angewandte Chemie International Edition, Volume 65, Issue 31, 27 July 2026.
Controlling biological systems with small‐molecule chromophores has evolved into a powerful strategy and is applied from chemical biology to medicine. However, the complexity of in vivo systems cannot be matched by a single wavelength of light. Developing methods to combine and individually control multiple chromophores is crucial.

Multicolor and Attenuated Light Intensity Responses in Protein Hydrogels Arising from Photoregulated Crosslink Dynamics

Angewandte Chemie International Edition, Volume 65, Issue 31, 27 July 2026.
A fully protein‐based hydrogel integrated two orthogonal photoreceptors to enable reversible manipulation of stiffness with red/far‐red light and irreversible gel‐sol transitions with green light. Unexpectedly, high‐intensity red light results in attenuated stiffening and dark‐adaptation, arising from increased crosslinking dynamics in the ...
