Chemical fungicides are an important component in disease management for most crops. As part of a program to discover natural product-based fungicides, several sensitive assay systems have been developed for the evaluation of naturally occurring antifungal agents. In this study, we focused on the discovery and evaluation of new natural product-based fungicides from Angelica sinensis (Dong Quai)...
NB-LRR-type disease resistance (R) genes have been used in traditional breeding programs for crop protection. However, functional transfer of NB-LRR-type R genes to plants in taxonomically distinct families to establish pathogen resistance has not been successful. Here we demonstrate that a pair of Arabidopsis (Brassicaceae) NB-LRR-type R genes, RPS4 and RRS1, properly function in two other Bra...
Pepper anthracnose caused by Colletotrichum species is one of the most important limiting factors for pepper production in Korea, its management being strongly dependent on chemicals. The aim of this work was to evaluate the possibilities of using silver nanoparticles instead of commercial fungicides. In this study, we evaluated the effect of silver nanoparticles against pepper anthracnose unde...
The Colletotrichum destructivum species complex – hemibiotrophic pathogens of forage and field crops
Colletotrichum destructivum is an important plant pathogen, mainly of forage and grain legumes including clover, alfalfa, cowpea and lentil, but has also been reported as an anthracnose pathogen of many other plants worldwide. Several Colletotrichum isolates, previously reported as closely related to C. destructivum, are known to establish hemibiotrophic infections in different hosts. The incon...
Colletotrichum dematium has been rarely reported from India before. The present case, a farmer, developed peripheral corneal ulcer five days following trauma with plant. At presentation his visual acuity was 6/60 (unaided) and 6/24P with pinhole. Slit lamp and fluorescent stain examination revealed paracentral corneal ulcer with irregular margins, stromal infiltration and multiple epithelial de...
Phytopathogens secrete effector proteins to manipulate their hosts for effective colonization. Hemibiotrophic fungi must maintain host viability during initial biotrophic growth and elicit host death for subsequent necrotrophic growth. To identify effectors mediating these opposing processes, we deeply sequenced the transcriptome of Colletotrichum higginsianum infecting Arabidopsis. Most effect...
FIRST REPORT OF COLLETOTRICHUM ALATAE ON WATER YAM (DIOSCOREA ALATA) CAUSING LEAF ANTHRACNOSE IN PUERTO RICO
The number of peroxisomes in a cell can change rapidly in response to changing environmental and physiological conditions. Pexophagy, a type of selective autophagy, is involved in peroxisome degradation, but its physiological role remains to be clarified. Here, we report that cells of the cucumber anthracnose fungus Colletotrichum orbiculare undergo peroxisome degradation as they infect host pl...
ABSTRACT Colletotrichum acutatum, which causes anthracnose disease on strawberry, can also persist on several other plant species without causing disease symptoms. The genetic and molecular bases that determine pathogenic and nonpathogenic lifestyles in C. acutatum are unclear. We developed a transformation system for C. acutatum by electroporation of germinating conidia, and transgenic isolate...
