The Structure of Carboxyl Methyltransferase Provides Insights Into the Substrate Specificity and Divergent Evolution of Iridoid

Plant Biotechnology Journal, Volume 24, Issue 6, Page 3708-3722, June 2026.
ABSTRACT Iridoids constitute a prominent class of plant‐specialised metabolites, with carbocyclic iridoids (e.g., geniposide) and secoiridoids (e.g., loganin) diverging early in their biosynthetic pathways. This divergence is marked by substrate‐specific carboxyl methyltransferases—GjGAMT and CrLAMT—that catalyse the decisive methylation step in ...

Major Components of Epicuticular Wax From Fruit of the Canadian Prairies: Saskatoon Berry (Amelanchier alnifolia), Canadian Dwarf Sour Cherry (Prunus × kerrasis), Haskap (Lonicera caerulea), and Red Twinberry (Lonicera utahensis)

European Journal of Lipid Science and Technology, Volume 128, Issue 5, May 2026.
Composition of chloroform extractable surface wax from fruit was determined by GC and GC/MS. The major components of Saskatoon berry wax were nonacosan‐10‐ol and nonacosane. Canadian sour cherry wax was enriched in the pentacyclic triterpenoids and haskap in nonacosan‐10‐ol and nonacosan‐5,10,‐diol. Red twinberry wax contained triterpenoids.
