Abstract: | "Species of the entomopathogenic fungi Metarhizium are used worldwide as biocontrol agents. Recently, other lifestyles have been associated with some Metarhizium species, which include their role as saprophytes, endophytes, and plant growth promoters. Herein, the effect of three Metarhizium anisopliae strains on the growth of Arabidopsis thaliana plantlets was evaluated using an in vitro split system. Arabidopsis fresh weight and total chlorophyll content significantly increased 7 days post-inoculation with the three Metarhizium anisopliae strains evaluated. The primary root length was promoted by all fungal strains without physical contact, whereas in direct contact primary root growth was inhibited. Volatile organic compounds identification revealed that during the interaction of Arabidopsis with Ma-20 and Ma-25 strains only beta-caryophyllene was produced, whereas in the Arabidopsis-Ma-28 interaction o-cymene was mainly emitted. The plant growth promoting effect induced by Metarhizium anisopliae strains was also achieved in Arabidopsis, tomato and maize plants grown in soil pots. Our results showed that three Metarhizium anisopliae strains were able to increase plant fresh weight, opening promising perspectives for field production, with the advantages of insect biocontrol and plant growth promotion induced by this species of fungus" |
