Momilactone A and B as Allelochemicals from MossHypnum plumaeforme: First Occurrence in Bryophytes

Convergent or parallel molecular evolution of momilactone A and B: Potent allelochemicals, momilactones have been found only in rice and the moss Hypnum plumaeforme

“…1; Kato-Noguchi, 2004;Kobayashi et al, 2007;Nozaki et al, 2007). Momilactone A and B in rice plants are known to be synthesized as a part of defensive responses and exhibit phytoalexin activity (e.g., Tamogami and Kodama, 2000;Jung et al, 2005;Okada et al, 2007) and allelopathic activity (e.g., Kato-Noguchi et al, 2002, 2008aKato-Noguchi, 2004;Kong et al, 2004).…”

Allelopathy and allelopathic substance in the moss Rhynchostegium pallidifolium

“…Momilactone A and B were recently isolated as allelopathic substances in two independent laboratories from the moss Hypnum plumaeforme, which often forms large pure colonies (Kobayashi et al, 2007;Nozaki et al, 2007). Although the two plants are taxonomically quit distinct, momilactone A and B have been found only in rice and H. plumaeforme to date.…”

Jasmonic acid, protein phosphatase inhibitor, metals and UV-irradiation increased momilactone A and B concentrations in the moss Hypnum plumaeforme

“…Potent growth inhibitors, momilactone A and B, were recently isolated from the moss, Hypnum plumaeforme (Kobayashi et al, 2007;Nozaki et al, 2007). Although H. plumaeforme is phylogenetically quite distinct from rice, momilactone A and B have so far been found only in rice and H. plumaeforme.…”
