WebDec 6, 2024 · Exposure of the citrus seeds to tryptoquialanine A resulted in a complete inhibition of germination and an altered metabolic response. Since this phytotoxic effect requires the extracellular export of tryptoquialanine A, we investigated the mechanisms of extracellular delivery of this alkaloid in P. digitatum . Web64 It was demonstrated that tryptoquialanine A (TA), purified from P. digitatum extracts, was 65 phytotoxic, showing herbicidal activity against Citrus sinensis seeds in a germination assay (Costa et 66 al. 2024).
