SAMANIEGO-GAMEZ, Blancka Y.; REYES-RAMIREZ, Arturo; MORENO-VALENZUELA, Oscar A.  and  TUN-SUAREZ, José M.. Induced systemic resistance against plant viruses elicited by inoculation with rhizobacteria Bacillus spp.. Rev. Protección Veg. [online]. 2017, vol.32, n.1, pp.10-22. ISSN 1010-2752.

Plants have developed various defense mechanisms against pathogen attack. After recognition of the pathogen, a number of responses including the expression of defense related genes are activated; one of them is the induced systemic resistance. Studies show that this resistance is independent of salicylic acid but requires jasmonic acid signaling and ethylene. Jasmonic acid and ethylene transduce the extracellular stimuli recognized by cell receptors to a large number of target molecules, which in a fully coordinated way, integrate the highly specific intracellular responses to external stimuli. Several studies have shown elicitors like Bacillus spp. to induce this mechanism with in the plant. While many studies show induction of resistance mechanisms by Bacillus spp. against fungi, bacteria, and nematodes, few studies have focused on the induction of virus resistance in the virus-plant-rhizobacteria interaction.  In this paper, the main signaling pathways of salicylic acid, jasmonic acid and ethylene, and the expression of genes involved in the interaction Bacillus-plant-virus are discussed. This review contributes to a better understanding of the effects of Bacillus spp. on the reduction of viral disease symptom expression and the possibility of Bacillus of being included into a sustainable vegetable management program
