Rhizobacteria isolated from wild dipterocarp saplings in Central Kalimantan, Indonesia, were subjected to Salkowski's reagent test, which is often used in detecting indolic substances. Among 69 isolates grown in a low-nitrogen medium supplemented with L-tryptophan (TRP), culture fluids of 29

Geometricin A (1), together with the known compounds (7E,12E,18S,20Z)-variabilin (2), clathryimine A (3), tryptophol (4), and L-tryptophan, has been isolated from the methanol extract of the Australian sponge Luffariella geometrica. The structure of the new compound geometricin A (1) was
In fungi, filamentous growth is a major developmental transition that occurs in response to environmental cues. In diploid Saccharomyces cerevisiae, it is known as pseudohyphal growth and presumed to be a foraging mechanism. Rather than unicellular growth, multicellular filaments composed
Reduction of ketosulfonyl indoles with sodium borohydride provides a ready entry to tryptophols in a regiocomplementary fashion with respect to the traditional oxirane ring-opening by indoles under Friedel-Crafts conditions. Compared to traditional β-ketosulfones, ketosulfonyl indoles show a peculiar behavior since
Trichoderma species belong to a class of free-living fungi beneficial to plants that are common in the rhizosphere. We investigated the role of auxin in regulating the growth and development of Arabidopsis (Arabidopsis thaliana) seedlings in response to inoculation with
