Plant Resistance Inducers against Pathogens in Solanaceae Species—From Molecular Mechanisms to Field Application

Abstract

This review provides a current summary of plant resistance inducers (PRIs) that have been successfully used in the Solanaceae plant family to protect against pathogens by activating the plant’s own defence. Solanaceous species include many important crops such as potato and tomato. We also present findings regarding the molecular processes after application of PRIs, even if the number of such studies still remains limited in this plant family. In general, there is a lack of patterns regarding the efficiency of induced resistance (IR) both between and within solanaceous species. In many cases, a hypersensitivity-like reaction needs to form in order for the PRI to be efficient. “-Omics” studies have already given insight in the complexity of responses, and can explain some of the differences seen in efficacy of PRIs between and within species as well as towards different pathogens. Finally, examples of field applications of PRIs for solanaceous crops are presented and discussed. We predict that PRIs will play a role in future plant protection strategies in Solanaceae crops if they are combined with other means of disease control in different spatial and temporal combinations.

Effect of Compost Extract Fortified with Tempe on Chili Mosaic Virus Disease

“…The fermentation liquid used in this study was derived from water extract of over-fermented tempe that reported to contain a non-proteinogenic amino acid, aminobutyric acid (Koh et al, 2012). β-aminobutyric acid (BABA), one of monomer of aminobutyric acid is known to have wide-ranging protection in a number of plant families against a variety of plant pathogens, nematodes and insect herbivores (Alexandersson et al, 2016). BABA has been demonstrated to reduce the performance of the pea aphid, Acyrthosiphon pisum on six legume plant species when applied as a root drench (Hodge et al, 2005).…”

Los fosfitos como alternativa para el manejo de problemas fitopatológicos

“…Due to their structural similarity, phosphites are thought to be akin to phosphates. However, the use of phosphites as fungicides and biostimulants to control plant pathogens is widely accepted, but their use as a phosphorus source in plant nutrition is currently debated (Borza et al, 2014;Gómez-Merino and Trejo-Téllez, 2015;Alexandersson et al, 2016;Manna et al, 2016). Such difference gives .…”

“…La sustitución del oxígeno da lugar a profundas diferencias en la manera en que los fosfatos y fosfitos se comportan en los organismos vivos (McDonald et al, 2001;Achary et al, 2017). Debido a su similitud estructural, los fosfitos son considerados como análogos de los fosfatos, sin embargo, el uso de los fosfitos como fungicidas y bioestimulantes para el control de patógenos de plantas es ampliamente aceptado, pero su utilización como fuente de fós-foro en la nutrición de plantas es actualmente debatida (Borza et al, 2014;Gómez-Merino y TrejoTéllez, 2015;Alexandersson et al, 2016;Manna et al, 2016). Además, esa diferencia da a los fosfitos una mayor movilidad en el suelo y en los tejidos de las plantas, así como una mayor capacidad para penetrar a través de hojas, tallos y raíces (Tkaczyk et al, 2016).…”

“…El uso de los fosfitos en la agricultura, se ha investigado principalmente por su acción en el control de organismos fitoparásitos o como fuente de nutrición en plantas cultivadas (Gómez-Merino y Trejo-Téllez, 2015; Alexandersson et al, 2016). Esto último puede ocurrir únicamente si los fosfitos se aplican al suelo y entran en contacto con bacterias que tienen la capacidad de oxidarlos a fosfatos (McDonald et al, 2001;Manna et al, 2016).…”

“…The use of phosphites in agriculture has been studied mainly because of their action to control phytoparasite organisms or as a nutrition source for cultivated plants (Gómez-Merino and Trejo-Téllez, 2015;Alexandersson et al, 2016). The latter may occur only if phosphites are applied to soil and come into contact with bacteria that have the capacity to oxidize them to phosphates (McDonald et al, 2001;Manna et al, 2016).…”
