Metabolomic and Single‐Cell Transcriptomic Analyses Shed Light on Secondary Metabolite Profiling and Potential Developmental Dynamics of Glandular Trichomes in Artemisia argyi

open access: yesPlant Biotechnology Journal, Volume 24, Issue 3, Page 1064-1081, March 2026.
ABSTRACT Plant glandular trichomes (GTs) are characterised by their ability to synthesise and store abundant secondary metabolites of significant biological importance. The medicinal plant Artemisia argyi exhibits a dense covering of GTs, yet the precise metabolic compositions and the developmental molecular dynamics of A.

An Ustilaginoidea virens Nuclear Effector SCRE7 Inhibits Rice Immunity via Suppressing OsLBD11/12‐Promoted Transcription of OsCPS2

open access: yesPlant Biotechnology Journal, Volume 24, Issue 3, Page 1305-1321, March 2026.
ABSTRACT Phytopathogenic fungi secrete a great number of effector proteins into various organelles of host plants and suppress plant immunity through different mechanisms. In this study, we identify SCRE7 as a unique nuclear effector that is essential for U. virens infection.

A Continuum of Pre‐Activated, Early, Coordinated and Multilayered Transcriptional Defence Responses Underpins Enhanced Resistance to Fusarium oxysporum in Vanilla planifolia

open access: yesPlant Pathology, Volume 75, Issue 2, March–April 2026.
In Vanilla planifolia, CR0020 resistance to Fusarium wilt is linked to early (4–8 hpi) ERF/MYB/WRKY reprogramming and a preactivated transcriptional state, activating ROS, lignification and phytoalexins. ABSTRACT Vanilla planifolia, the main species cultivated for vanilla production, is severely threatened by Fusarium oxysporum f. sp. radicis‐vanillae (
