Phytotoxins from Tithonia diversifolia [PDF]

Journal of Natural Products, 2015
Tithonia diversifolia (Mexican sunflower) is a dominant plant of the Asteraceae family, which suggests it produces allelochemicals that interfere with the development of surrounding plants. The study described herein was conducted to identify the compounds that have phytotoxic activity in T. diversifolia extracts.

The Search for Quorum Sensing in Botrytis cinerea: Regulatory Activity of Its Extracts on Its Development

Plants, 2020
Botrytis cinerea is a phytopathogenic fungus that causes large crop and post-harvest losses. Therefore, new and effective strategies are needed to control the disease and to reduce resistance to fungicides.

Two Homologues of the Global Regulator Csr/Rsm Redundantly Control Phaseolotoxin Biosynthesis and Virulence in the Plant Pathogen Pseudomonas amygdali pv. phaseolicola 1448A

Microorganisms, 2020
The widely conserved Csr/Rsm (carbon storage regulator/repressor of stationary-phase metabolites) post-transcriptional regulatory system controls diverse phenotypes involved in bacterial pathogenicity and virulence. Here we show that Pseudomonas amygdali

Bacillus subtilis PTA-271 Counteracts Botryosphaeria Dieback in Grapevine, Triggering Immune Responses and Detoxification of Fungal Phytotoxins

Frontiers in Plant Science, 2019
Plant pathogens have evolved various strategies to enter hosts and cause diseases. Particularly Neofusicoccum parvum, a member of Botryosphaeria dieback consortium, can secrete the phytotoxins (-)-terremutin and (R)-mellein during grapevine colonization.

Phytotoxins produced by Lasiodiplodia laeliocattleyae involved in Botryosphaeria dieback of grapevines in Brazil

Phytopathologia Mediterranea, 2019
Botryosphaeria dieback (BD) is an important trunk disease affecting grapevines. Several Lasiodiplodia species have been shown to be involved in BD affecting the perennial organs of grapevine, mainly causing cankers.
