Amino‐Functionalized Mesoporous SiO2 Hollow Nano‐Doughnuts for Enhanced Gas Adsorption and Specific Foodborne Pathogen Recognition in Point‐of‐Care Detection

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Developing rapid, precise gas sensors for Listeria monocytogenes (LM) biomarker detection faces challenges due to suboptimal gas‐solid interactions. Herein, we report the rational synthesis of amino‐functionalized mesoporous SiO2 hollow nano‐doughnuts (MS‐2‐NH2‐2) via modification with (3‐aminopropyl) trimethoxysilane (AAPTMS), which enables ...

Domestication‐associated reduction of methyl salicylate in tomato root and its significance for resistance to root‐knot nematode

New Phytologist, Volume 252, Issue 1, Page 414-426, October 2026.
Root volatile profiling reveals domestication‐associated variation in methyl salicylate (MeSA) accumulation in tomato. Summary Methyl salicylate (MeSA) plays diverse roles in the aerial parts of plants. By contrast, its biosynthesis and function in roots remain poorly understood.

Evolution‐Inspired Engineering of Diterpene Biosynthesis via Chloroplast Genome Modification

Plant Biotechnology Journal, Volume 24, Issue 10, Page 5510-5525, October 2026.
ABSTRACT Terpenes constitute the largest and most structurally diverse class of plant secondary metabolites, with critical roles in plant‐environment interactions and broad industrial applications. Although nuclear genome engineering of terpene pathways has been extensively explored, chloroplast genome engineering remains largely undeveloped, with most
