Aspergillus flavus YRB2 from Thymelaea hirsuta (L.) Endl., a non-aflatoxigenic endophyte with ability to overexpress defense-related genes against Fusarium root rot of maize

Table 6 Total phenolic content and activities of peroxidase and polyphenol oxidase enzymes of maize roots infected with Fusarium root rot in response to colonization with endophytic Aspergillus flavus YRB2 at 45 days post infection*

Treatment	Total phenols (mg.g^− 1 fresh wt)	Peroxidase (∆A₄₇₀ min^− 1 g^− 1 fresh wt)	Polyphenol oxidase (∆A₄₂₀ min^− 1 g^− 1 fresh wt)
C	115.0 ± 4.5^d	1.053 ± 0.1^d	1.522 ± 0.1^d
P	272.3 ± 3.2^b	2.941 ± 0.2^b	2.033 ± 0.2^b
E	215.4 ± 3.6^c	2.520 ± 0.2^c	1.791 ± 0.1^c
P + E	306.1 ± 3.5^a	3.245 ± 0.1^a	2.787 ± 0.2^a

*In each column, values followed by the same letter are not significantly different according to Tukey’s HSD test (p ≤ 0.05), each value represents the mean of five replicates ± SD. Where, C: non-colonized with A. flavus YRB2 and uninfected with F. solani, P: non-colonized with A. flavus YRB2 and infected with F. solani, E: uninfected with F. solani and colonized with A. flavus YRB2, and P + E: infected with F. solani and colonized with A. flavus YRB2
