For plant extracts, the situation is even worse: leaf homogenates are loaded with polyphenols and ascorbate that reduce DTNB independently of any thiol, generating "cysteine" signals in tissues where cysteine has been genetically depleted

Additionally, we synthesized another tripeptide (Glu-Pro-Ala), which contains glutamate along with two different amino acids, and investigated its effects in triggering systemic Ca 2+ signal propagation in plants
