Resumen
[EN] Halo blight disease of beans (Phaseolus vulgaris L.), caused by the bacterium Pseudomonas
syringae pv. phaseolicola (Pph), is responsible for severe losses in crop production worldwide. As the
current agronomic techniques used are not effective, it is necessary to search for new ones which
may prevent disease in common bean. In this study, we challenged four plant-based preparations
(PBPs), with no other agronomic uses, as they come from industrial waste (grapevine pomace (RG)
and hop residue (RH)) or wild plants (Urtica dioica (U) and Equisetum sp. (E)), to be used as immune
defense elicitors against Pph in common bean. After studying their inhibitory effect against Pph
growth by bioassays, the two most effective PBPs (RG and U) were applied in common bean plants.
By measuring the total H2O2, lipid peroxidation, and antioxidant enzymatic activities, as well as the
expression of six defense-related genes—PR1, WRKY33, MAPKK, RIN4, and PAL1—, it was observed
that U-PBP application involved a signaling redox process and the overexpression of all genes, mostly
PR1. First infection trials in vitro suggested that the application of U-PBP involved protection against
Pph. The elicitation of bean defense with U-PBP involved a decrease in some yield parameters, but
without affecting the final production. All these findings suggest a future use of U-PBP to diminish
halo blight disease.
