The Sweetpotato Black Rot Pathogen Ceratocystis fimbriata

Molecular Plant Pathology, Volume 27, Issue 11, November 2026.
We review current knowledge of the soilborne Ceratocystis fimbriata pathogen's biology, epidemiology, virulence and management, and identify priorities for future research. ABSTRACT Black rot, caused by the soilborne fungus Ceratocystis fimbriata, is a major postharvest disease of sweetpotato (Ipomoea batatas) worldwide.

High‐Resolution LC–MS/MS Characterization of Budmunchiamine‐Type Alkaloids in Albizia niopoides

Rapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.
ABSTRACT Rationale Budmunchiamines are macrocyclic spermine alkaloids that constitute a distinctive class of polyamine natural products predominantly found in species of the genus Albizia. Comprehensive characterization of these compounds remains challenging because of their structural diversity and the limited availability of reference standards. This

One‐Shot Pd(II)‐Catalyzed Multiple C–H Activation Enables Modular Construction of Fluorenylidene Oxindole‐Based Multi(Polycyclic) Aromatic Enes

Chemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
A one‐shot Pd(II)‐catalyzed C─H activation strategy enables the rapid conversion of simple linear propiolamides into structurally diverse mono‐, di‐, and tri‐olefin‐bridged MPAEs. This cascade process orchestrates up to six sequential C–H activations in a single operation, providing streamlined access to highly conjugated architectures.
