Overview

Randomized trial reveals conservation of BMAA across plant clades, suggesting complex npAA metabolism.

Key Points

  • The aim is to investigate the production and conservation of BMAA and its isomers across plant evolution.
  • Studied 75 plants from 11 clades under various growth conditions.
  • Used validated methods to quantify BMAA and untargeted metabolomics for isomer discovery.
  • Detected BMAA in multiple plant groups including Acrogymnospermae and Rosids.
  • BMAA was more frequently detected in tissue-cultured plants than in field or agricultural samples.
  • Quantified BMAA levels in specific plant species such as Azolla filiculoides and Myriophyllum aquaticum.
  • Findings emphasize the need for deeper understanding of non-protein amino acid metabolism in higher plants.
