Plant growth regulators from the liquid culture of Lepista sordida

Abstract

“Fairy rings” are zones that stimulate or inhibit grass growth, caused by interactions between a fungus and a grass. Lepista sordida is one of the fairy ring-forming fungi. (1S,2S)-1-(4-Chloro-3-methoxyphenyl)propane-1,2-diol (1) along with ten compounds (2–11) were isolated from the culture broth and mycelia of L. sordida. The structures were identified by spectroscopic data analyses, and this was the first reported isolation of 1 from a natural source. The plant growth regulatory activity of 3–6 was investigated using bentgrass seedlings. Compound 3 promoted root growth at 0.1 μmol/paper, while inhibited it at 1 μmol/paper. Compound 4 inhibited root growth at 0.1 and 1 μmol/paper. Compound 6 significantly promoted shoot growth at 1 μmol/paper.

Accepted manuscripts

Accepted manuscripts are PDF versions of the author’s final manuscript, as accepted for publication by the journal but prior to copyediting or typesetting. They can be cited using the author(s), article title, journal title, year of online publication, and DOI. They will be replaced by the final typeset articles, which may therefore contain changes. The DOI will remain the same throughout.
