Pseudomonas sp. DF41 is a biocontrol agent capable of suppressing Sclerotinia sclerotiorum-mediated stem rot of canola. Using transposon mutagenesis, we identified two mutants with greatly reduced antifungal (AF) activity. The first mutant had an insertion in gacS, forming part of the GacS/GacA regulatory system. The second mutation was in a gene involved in lipopeptide (LP) synthesis suggestin...

BACKGROUND Biocontrol agents are regarded as promising and environmental friendly approaches as agrochemicals for phytodiseases that cause serious environmental and health problems. Trichoderma species have been widely used in suppression of soil-borne pathogens. In this study, an endophytic fungus, Trichoderma gamsii YIM PH30019, from healthy Panax notoginseng root was investigated for its bio...

Intensive cultivation of plants in the monoculture field system in order to feed the continuously growing human population creates a need for their protection from the variety of natural competitors such as: bacteria, fungi, insects as well as other plants. The increase in the use of chemical substances in the 20th century has brought many effective solutions for the agriculture. However, it wa...

Early research leading to the successful biological control of invasive species such as Opuntia spp., and Hypericum perforatum set examples and provided data useful for research programs that would follow. However, this early work failed to become established as a source of applicable principles for later workers in weed biocontrol. Recently, retrospective and parallel studies have been suggest...

Globally, governments spend significant amounts of money attempting to prevent or mitigate the negative impacts invasive species using different strategies, including classical biological control for that are widespread in landscape. Arriving at point biocontrol release requires investment time and funds research testing, success agent is uncertain. We present a numerical model designed assist ...

The endophytic bacterium Pseudomonas aurantiaca PB-St2 exhibits antifungal activity and represents a biocontrol agent to suppress red rot disease of sugar cane. Here, we report the completely sequenced 6.6-Mb genome of P. aurantiaca PB-St2. The sequence contains a repertoire of biosynthetic genes for secondary metabolites that putatively contribute to its antagonistic activity and its plant-mic...

Bacillus pumilus is a Gram-positive bacterium widely used in agriculture both as an antifungal and as a growth-promoting symbiont. B. pumilus is rarely infectious but has recently been shown to infect humans. Here, we present the complete genome of B. pumilus phage Glittering, a potential biocontrol agent for B. pumilus.

Rhodotorula kratochvilovae strain LS11 is a biocontrol agent (BCA) selected for its antagonistic activity against several plant pathogens both in the field and postharvest. Genome assembly includes 62 contigs for a total of 22.56 Mbp and a G+C content of 66.6%. Genome annotation predicts 7,642 protein-encoding genes.
