A, and ethylene that have been included as optimistic controls of defensesignaling pathways. Immediately after two weeks from transplanting, plants have been sprayed with aqueous solutions of BP178, BP100 or flg15 at 125 , SA, and JA at 2.five mM (Sigma-Aldrich, St. Louis, MO, USA) for the run-off point. For the ethylene therapy, plants had been enclosed within a sealed chamber and exposed to ethylene obtained by reacting ethephon (1 mM) (Nufarm Espa , Spain) with a disodium hydrogen phosphate buffer (two.five mM) (Zhang and Wen, 2010). The concentrations in the peptides BP100 and BP178 had been chosen on the basis from the concentrations that had been discovered productive against infections by plant pathogens observed in planta assays that were previously reported (Badosa et al., 2017; Caravaca-Fuentes et al., 2021). In the case of SA, JA, and ethylene, the concentrations had been selected since they were applied in other reports on topical application of defense elicitors in plants (Reignault and Walters, 2007; Rivas-San and Plasencia, 2011; Zhang et al., 2011). Manage plants have been treated with distilled water. About 24 h just after item application, leaf samples were collected, promptly frozen in liquid nitrogen, and stored at -80 C. For total RNA extraction, the plant material was ground to a fine powder in liquid nitrogen with all the Tissuelyzer II method (Qiagen, Hilden, Germany). Total RNA was extracted from leaves employing TriZol R (Invitrogen, Life Technologies) as mTOR Inhibitor supplier outlined by the manual in the manufacturer. Following the extraction protocol, RNA samples had been routinely subjected to DNAse treatmentFrontiers in Plant Science | www.frontiersinOctober 2021 | Volume 12 | ArticleMontesinos et al.BP178 Bactericidal and Elicitor PeptideTABLE 1 | Associated functions to overexpressed defense related genes, in line with RT-qPCR, in tomato plants in response to BP178 remedy.
