Trichoderma atroviride ID20G inoculation ameliorates drought stress-induced damages by improving antioxidant defence in maize seedlings

Combined inoculation of arbuscular mycorrhizal fungi, Pseudomonas fluorescens and Trichoderma spp. for enhancing defense enzymes and yield of three pepper cultivars

“…Application of Tri reduced PPO, CAT activities but remained unchanged POD, SOD levels ( Table 5), which is inconsistent with a previous study in maze plants under drought stress (Guler et al, 2016). Instead of decreasing PPO, SOD activity in leaves as AM plants did, AM+Tri did not change considerably PPO, SOD levels whereas, intriguingly, these enzyme activities in the three-inoculant treatment (AM+Tri+Pse) leaped ( Table 5).…”

Growth-promoting bacteria alleviates drought stress of G. uralensis through improving photosynthesis characteristics and water status

“…These results indicated that chlorophyll content may adjust water relation, thereby further affecting photosynthesis and improving the resistance of G. uralensis under drought stress (Table 2). Endophyte inoculation has a positive effect on the maintenance of chlorophyll when subjected to drought stress; however, the underlying mechanism remains unknown (Guler et al 2016;Mo et al 2016). Our study found that the Chl a, Chl b, and the Chl a+b contents decrease under drought stress.…”

Fungal endophytes and a virus confer drought tolerance to Nicotiana benthamiana plants through modulating osmolytes, antioxidant enzymes and expression of host drought responsive genes

“…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).…”

“…For example, inoculation with a strain of Chaetomium globosum resulted in an increased water content of wheat leaves subjected to water stress as compared to nonendophytic counterparts (Cong et al, 2015). Also, Trichoderma atrovride colonization in maize (Guler et al, 2016) and T. hamatum colonization in cacao (Bae et al 2009) showed a relative increase in water status under stress conditions. In similar research, it was shown that endophytic plants use significantly less water than non-endophytic plants (Chepsergon et al 2014).…”
