chamaecyparis lawsonia, which brings beauty in parks and green space, is attacked by a variety of pathogenic agents specially fungi. in this study, some chamaecyparis lawsonia available in parks that had disease symptoms were sampled. after sample collection, in order to isolate fungal pathogens, cuts of the infected plant tissues were placed on pda (potato dextrose agar) and later were put on...
The oomycete Pythium periplocum is an aggressive mycoparasite of a number of plant pathogenic fungi and oomycetes and therefore has potential as a biological control agent. Here, we report the first draft genome sequence of P. periplocum, which comprises 35.89 Mb. It contains 1,043 scaffolds and 14,399 predicted protein-coding genes.
Fungal diseases of plants represent one of the most eminent threats to agriculture. Given the food needs of a growing world population and that more and more crops are devoted to fuel production, the necessity to develop crops with better resistance to disease is increasing. To accomplish this, the mechanisms that plant pathogenic fungi use to colonize plants need to be elucidated. As of now, t...
Streptomyces sp. strain Wb2n-11, isolated from native desert soil, exhibited broad-spectrum antagonism against plant pathogenic fungi, bacteria, and nematodes. The 8.2-Mb draft genome reveals genes putatively responsible for its promising biocontrol activity and genes which enable the soil bacterium to directly interact beneficially with plants.
The genome of Paenibacillus polymyxa Sb3-1, a strain that shows antagonistic activities against pathogenic fungi and bacteria, consists of one 5.6-Mb circular chromosome and two plasmids of 223 kb and 8 kb. The genome reveals several genes that potentially contribute to its antagonistic and plant growth promotion activity.
We report here the whole-genome shotgun sequence of Bacillus amyloliquefaciens strain UASWS BA1, isolated from inner wood tissues of a decaying Platanus × acerifolia tree. This strain proved to be antagonistic to several plant pathogenic fungi and oomycetes and can be developed as a biological control agent in agriculture.
Oligomycin F, a new homologue of oligomycin A (1), was isolated from a Streptomyces species and structure 2 was deduced by NMR methods. Compound 2 is highly active against plant pathogenic fungi and is an extremely potent suppressive agent for various immunological systems.
Paracoccidioides is a fungal pathogen and the cause of paracoccidioidomycosis, a health-threatening human systemic mycosis endemic to Latin America. Infection by Paracoccidioides, a dimorphic fungus in the order Onygenales, is coupled with a thermally regulated transition from a soil-dwelling filamentous form to a yeast-like pathogenic form. To better understand the genetic basis of growth and ...
Our review includes a genomic survey of multitude reactive oxygen species (ROS) related intra- and extracellular enzymes proteins among fungi Basidiomycota, following their taxonomic classification within the systematic classes orders, focusing on different fungal lifestyles (saprobic, symbiotic, pathogenic). Intra- ROS metabolism-involved (49 protein families, summing 4170 models) were searche...
Numerous plant species, which are main components of various mixtures used in animal nutrition, can be contaminated by mycotoxins created by large number of pathogenic and toxigenic fungi (moulds). From the aspect of animal nutrition, most important are cereals and oil crops (in form of meals) because they constitute the highest share in preparation of animal food, and on the other hand, they a...
