“…increased leaf greenness in maize, which enhanced the vigour when an adequate carbon source was available for plant development. In our study, the isolate E-284 did now show any effect on chlorophyll content, while a positive effect of fungal endophytes on plant chlorophyll is common (Bayat et al, 2009;Guler et al, 2016;Khan et al, 2013;Khan et al, 2015;Mastouri et al, 2012;Shukla et al, 2012;Sun et al, 2010b;Waqas et al, 2012;Zhang and Nan, 2007), neutral or negative (Pandey et al, 2016;Ren et al, 2011;Tian et al, 2015b). It is understandable that virus infection severely reduces plant chlorophyll content (Dai et al, 2009;Guo et al, 2005;Plattt et al, 1979).…”
