“…Besides, the resistance might also involve the ability of the plant to form a specific structure that can inhibit the development of pathogens, this structural changes such as the lack of stomata per unit area of the leaf, thickness of the cuticle layer, the formation of tissue of cork, or the production of toxic substances before or after the pathogens entered the plant tissue, so the pathogens fail to develop further and cause disease (Andersen et al, 2018). Pathogens that successfully infect tissue can cause damage to epidermal cells, the nucleus of the cells and other organelles, ultimately causing severe damage to the leaves (Dalimunthe et al 2015).…”
