“…The regulation of gene expression under the effects of epigenetic mechanisms is another field not yet explored involving the M. perniciosa pathosystem and its hosts. The understanding and manipulation of resistance responses of plants with great agronomic importance affected by biotic and abiotic factors from an epigenetic standpoint is already well described for some species [ 41 , 103 , 104 , 105 ]. In this sense, there are no reports of Theobroma cacao , the main host of M. perniciosa , so there are no methods that aim to identify epigenetic mechanisms associated with resistance to the fungus.…”

“…The accumulation of miRNAs differentially modulated by drought stress was affected by the grafting of grapevine [ 182 ]. Citrus rootstocks affected the hypermethylation and hypomethylation in grafted scion under drought conditions [ 183 ]. The DNA methylation pattern in apples was transferred from donor trees to newly grafted trees [ 184 ].…”

“…Healthy growth and survival of grafted scion varieties are generally linked with the less drought damaging effect which might be associated with the increased rate of enzymatic activity through the relatively tolerant wild grapevines that can efficiently upregulate the cellular activities and subsequently reduce the production of ROS in the shoot and leaves of scion. Increased enzymatic activities were also observed by Santos et al [39] in drought tolerant citrus Rangpur lime and Citrus sunki rootstocks, which were attributed by the efficiently upregulation of APX enzyme activities that assist the elastic properties of grafted 'Citrus latifolia Tanaka' cell wall which increased the plant shoot growth under drought stress conditions. Similarly enzymatic activities of peroxidase were also reported to be upregulated significantly in Flame Seedless cultivar when grafted on relatively drought tolerant grapevine rootstock Paulsen [46].…”

“…Plants also develop several antioxidative system which reduce the negative effect of ROS accumulation by detoxify them into less toxic compounds [ 38 , 39 ]. To eliminate and degrade harmful oxygen species at early stage, SOD and CAT are considered as most active enzymes that maintain oxidative equilibrium during stress condition [ 40 ].…”
