Best insight from top research papers
Beauveria bassiana is an entomopathogenic fungus used in agriculture as a biological controller worldwide. It is a well-studied organism, but there are no genomic studies of B. bassiana isolates from Central American and Caribbean countries . B. bassiana is the most common species of Beauveria and is known for causing muscardine, a disease in silkworms . It can be cultivated on solid or liquid media, and cultivating it on liquid media is expected to shorten the cultivation time and leave no waste . B. bassiana has been used as a biological control agent against Nilaparvata lugens Stal., a major pest of rice, and has been found to reduce oviposition and hatchability of eggs .

How to make gene silencing in beauveria bassiana?5 answersGene silencing in Beauveria bassiana can be achieved through various methods. One approach is the integration of egfp-double-stranded RNA (dsRNA) into the fungus using a protoplast integration method. Another method involves the utilization of the anti-carboxin gene as a selection marker for genetic transformation. Additionally, the alc regulon system based on the AlcR transcription factor and alcA promoter from Aspergillus nidulans can be introduced into B. bassiana to control exogenous gene expression. Agrobacterium-mediated transformation using a phosphinothricin acetyltransferase (bar) gene as a selectable marker has also been developed for B. bassiana. These methods provide effective tools for manipulating gene expression and studying the molecular basis of virulence and host specificity in B. bassiana.
What are the non-enzymatic proteins produced by Beauveria bassiana?5 answersNon-enzymatic proteins produced by Beauveria bassiana include polyketide synthase genes pks14 and pks15, which are important for insect virulence and crosstalk with biosynthetic clusters encoding insect-virulent metabolites. Additionally, the entomotoxic protein BBII, designated as BBF2, has been identified and found to be highly virulent against certain insect pests. Furthermore, a candidate aegerolysin protein called beauveriolysin A (BlyA) has been identified in B. bassiana, which is involved in promoting the entomopathogenic and antagonistic activity of the fungus.
How does the insect host species affect the action speed of the entomopathogneic fungus Beauveria bassiana?5 answersThe insect host species can affect the action speed of Beauveria bassiana. In laboratory experiments, B. bassiana was found to be more virulent against Bactericera cockerelli nymphs maintained on tomato compared to nymphs maintained on potato or chilli peppers. The expression of Egf1.0 in B. bassiana significantly enhanced its pathogenicity against Helicoverpa armigera, reducing the median lethal concentration (LC50) and median lethal time (LT50). Additionally, the study found that the host plant species can modify the outcomes of insect-pathogen interactions, with B. bassiana being more effective against B. cockerelli nymphs on tomato compared to chilli pepper. These findings suggest that the insect host species can influence the virulence and action speed of B. bassiana.
What is Beauveria bassiana?5 answersBeauveria bassiana is an entomopathogenic fungus used in agriculture as a biological controller worldwide. It is a globally distributed fungus that infects insects and produces various secondary metabolites to support its pathogenesis. Two polyketide synthase genes, pks14 and pks15, are important for insect virulence in B. bassiana. These genes and their clusters are associated with key pathways in insect pathogenesis and secondary metabolism. B. bassiana is commonly known as a white muscardine fungus due to the white color of its sporulating colonies. It is widely used as a biocontrol agent against various insect pests. B. bassiana is categorized as a type of biopesticide based on entomopathogenic fungi, and it has shown effectiveness against pests such as whiteflies, aphids, thrips, grasshoppers, and certain types of beetles.
What is Beauveria bassiana?3 answersBeauveria bassiana is a type of fungus belonging to the class Deuteromycetes. It is a widely distributed soil-inhabiting fungus and is categorized as a white muscardine fungus due to the white color of its sporulating colonies. B. bassiana is known for its biocontrol properties and is used as a biocontrol agent against various insects, including the larval stage of the silkworm. It is also used as a biological preparation for preventing and controlling euwallacea fornicatus, a type of pest. B. bassiana has been isolated from soybean ergania doriae yunnanus heller and is used as an active ingredient in insecticides. It has a specific pathogenic effect on soybean ergania doriae yunnanus heller and can effectively kill this pest. Additionally, B. bassiana is used for preventing and controlling piercing-sucking pests such as aleyrodid and aphid in crop production. It is also used for controlling mosquitoes and has shown effectiveness in killing various mosquito species in laboratory research.
What is Beauveria bassiana and what diseases does it cause?4 answersBeauveria bassiana is an entomopathogenic fungus that is widely distributed in soil and is known for its high efficacy against agricultural insect pests. It is also a plant symbiont/endophyte and has been shown to successfully colonize plants, such as Vicia faba bean, reducing the level of infection with phytopathogens and decreasing the development of root rot disease. B. bassiana is categorized as a white muscardine fungus and is used as a biocontrol agent against the larval stage of silkworms. It has also been found to be effective against Psoroptes ovis var. cuniculi, the causative agent of psoroptic mange, both in vitro and in vivo, with a therapeutic response greater than that of the anti-parasitic drug ivermectin. B. bassiana can be used as a biological material to control mosquitoes and has been proven effective against Culex, Aedes, and Anopheles species in laboratory research. Additionally, B. bassiana has a specific pathogenic effect on soybean ergania doriae yunnanus heller and can effectively kill this pest without causing damage to soybean oxidation.
