Allelochemicals from Stauranthus perforatus, a Rutaceous tree of the Yucatan Peninsula, Mexico.
Aqueous leachates and a CHCl3-MeOH extract of roots of Stauranthus perforatus showed a significant phytotoxic effect on Amaranthus hypochondriacus and Echinochloa crus-galli and the decomposition of the leaves and roots in the soil had a significant inhibitory effect on the growth of weeds. Expand
Allelochemical Effects of Volatile Compounds and Organic Extracts from Muscodor yucatanensis, a Tropical Endophytic Fungus from Bursera simaruba
In general, extracts inhibited plants more than endophytic or phytopathogens fungi, and the possible allelopathic role that metabolites of M. yucatanensis play in its ecological interactions with its host plant and other organisms is discussed. Expand
Pentacyclic Triterpenes with Selective Bioactivity from Sebastiania adenophora Leaves, Euphorbiaceae
Six known pentacyclic triterpenes possessing oleanane, lupane, or taraxerane-type skeletons were isolated from the leaves of Sebastiania adenophora (Euphorbiaceae) and are reported for the first timeExpand
Naphthoquinone spiroketal with allelochemical activity from the newly discovered endophytic fungus Edenia gomezpompae.
This is the first report of allelochemicals with antifungal activity from the newly discovered endophytic fungus E. gomezpompae, and the acetylated derivatives of preussomerin EG1, 1a and 1b exhibited significant bioactivity against all microorganisms tested with the exception of Alternaria solani.

Comparative study of two GH19 chitinase‐like proteins from Hevea brasiliensis, one exhibiting a novel carbohydrate‐binding domain
Two CLPs of the GH19 family from the rubber tree Hevea brasiliensis were cloned, expressed and characterized and were highly thermostable and exhibited antifungal activity against Alternaria alternata, suggesting their participation in plant defense mechanisms. Expand
Naphthoquinone spiroketals and organic extracts from the endophytic fungus Edenia gomezpompae as potential herbicides.
From the fermentation mycelium of the endophytic fungus Edenia gomezpompae were obtained several phytotoxic compounds including two new members of the naphthoquinone spiroketal family, namely, palmarumycin EG1 and preussomerin EG4, which were unambiguously determined by X-ray analysis. Expand
A new endophytic ascomycete from El Eden Ecological Reserve, Quintana Roo, Mexico
During a preliminary survey to report the biodiversity of endophytic fungi associated with leaves of some woody plants from El Eden Ecological Reserve in Mexico, a new fungus was isolated from Callicarpa acuminata leaves and proposed to be a member of the Pleosporaceae (Pleosporales) and has not been previously described.

Secondary metabolites of endophytic Xylaria species with potential applications in medicine and agriculture
Fungal endophytes are important sources of bioactive secondary metabolites. The genus Xylaria Hill (ex Schrank, 1789, Xylariaceae) comprises various endophytic species associated to both vascular andExpand
Antifungal Volatile Organic Compounds from the Endophyte Nodulisporium sp. Strain GS4d2II1a: a Qualitative Change in the Intraspecific and Interspecific Interactions with Pythium aphanidermatum
This study demonstrates volatile organic compounds (VOCs) production as one of the defense mechanisms of the antagonistic endophyte Nodulisporium sp. GS4d2II1a, and the volatile changes in two timesExpand
