Endophytic fungi Beauveria bassiana Balsamo accelerates growth of common bean (Phaeseolus vulgaris L.)

Abstract

Background: Common bean (Phaseolus vulgaris L.) is a source of antioxidant-containing vegetable protein that is beneficial to human health. The intense cultivation of common bean may result in environmental degradation. Thus, environmentally friendly cultivation methods that use an endophyte to improve productivity are needed. An entomopathogenic fungus, Beauveria bassiana, can serve as an endophyte that stimulates the growth of Gossypium. Therefore, we isolated and identified B. bassiana and also examined its function as a beneficial endophyte that promotes the growth of common bean. Results: An entomopathogenic fungus, B. bassiana, was collected and identified based on macroscopic and microscopic characteristics that were observed during morphological examination. B. bassiana was propagated and inoculated into common bean via seed soaking, soil wetting, and leaf spraying. The soil-wetting and leaf-spraying methods used to inoculate B. bassiana effectively enhanced the growth of common bean, which was observed at day 10 postinoculation. However, no significant growth enhancement of common bean was observed when the seed-soaking inoculation method was used. Conclusions: These results suggest a positive correlation between the B. bassiana inoculation method and growth enhancement of common bean. This study showed the endophytic potency of the fungus that may be used in the development of environmentally friendly cultivation methods of common bean.

Effects of Beauveria bassiana (Hypocreales) on plant growth and secondary metabolites of extracts of hydroponically cultivated chive (Allium schoenoprasum L. [Amaryllidaceae])

“…The root lengths varied significantly among treatments, and the shortest length was observed in plants exposed to the highest concentration of fungal treatment, which may suggest that fungus might have had a negative effect on root length. In a more recent study, B. bassiana inoculation had a positive influence on plant growth parameters including root length of common beans ( Phaeseolus vulgaris ) (Afandhi et al., 2019). Nevertheless, the colonization of plant tissues by fungal endophytes can be influenced by many factors, such as inoculation method, species and fungal strain (Muvea et al., 2014; Afandhi et al., 2019).…”

Increased fecundity of Aphis fabae on Vicia faba plants following seed or leaf inoculation with the entomopathogenic fungus Beauveria bassiana

“…bassiana is suppressing the plant defense against aphids via defense pathway cross talk. Several studies have found that EEF benefit plant growth [39–44], and that EEF can translocate nitrogen to their plant host [45]. Specifically, endophytic B .…”

Endophytic colonization of tomato by Beauveria bassiana for control of the greenhouse whitefly, Trialeurodes vaporariorum (Hemiptera: Aleyrodidae)

“…Beauveria bassiana (Balsamo) Vuillemin (Hypocreales: Cordycipitaceae) is a soil borne fungus that attacks an extensive host range of insects at all stages of development (Ownley et al, 2004). In addition to insecticidal activity, B. bassiana has been found to protect plants against certain plant pathogens (Ownley et al, 2004; as well as to function as a biofertilizer (Vega, 2018;Afandhi et al, 2019). Different isolates of B. bassiana have been reported as naturally occurring endophytes in a variety of plant species such as tomato, potato, maize, cotton, cucumber, melon, and rice (Vega, 2008;Brownbridge et al 2012;Vidal, Jaber, 2015).…”
