“…in response to fungal and bacterial infection (Grosskinsky et al, 2011;Song et al, 2019). Capsidiol is toxic to many oospore and fungal pathogens, such as Phytophthora capsici and Botrytis cinerea (Stoessl et al, 1972;Ward et al, 1974), and suppresses the mobility of false rootknot nematode Nacobbus aberrans (Godinez-Vidal et al, 2010). We found that A2-O induces the expression of CYP71D7-like protein, the closest homologue to CYP71D20 from Nicotiana benthamiana, which converts 5-epiaristolochene to capsidiol (Ralston et al, 2001).…”

Root-knot nematodes (RKNs) are among the most devastating pests in agriculture. Solanum torvum Sw. (Turkey berry) has been used as a rootstock for eggplant (aubergine) cultivation because of its resistance to RKNs, including Meloidogyne incognita and M. arenaria. We previously found that a pathotype of M. arenaria, A2-J, is able to infect and propagate in S. torvum. In vitro infection assays showed that S. torvum induced the accumulation of brown pigments during avirulent pathotype A2-O infection, but not during virulent A2-J infection. This experimental system is advantageous because resistant and susceptible responses can be distinguished within a few days, and because a single plant genome can yield information about both resistant and susceptible responses. Comparative RNA-sequencing analysis of S. torvum inoculated with A2-J and A2-O at early stages of infection was used to parse the specific resistance and susceptible responses. Infection with A2-J did not induce statistically significant changes in gene expression within one day post-inoculation (DPI), but afterward, A2-J specifically induced the expression of chalcone synthase, spermidine synthase, and genes related to cell wall modification and transmembrane transport. Infection with A2-O rapidly induced the expression of genes encoding class III peroxidases, sesquiterpene synthases, and fatty acid desaturases at 1 DPI, followed by genes involved in defense, hormone signaling, and the biosynthesis of lignin at 3 DPI. Both isolates induced the expression of suberin biosynthetic genes, which may be triggered by wounding during nematode infection. Histochemical analysis revealed that A2-O, but not A2-J, induced lignin accumulation at the root tip, suggesting that physical reinforcement of cell walls with lignin is an important defense response against nematodes. The S. torvum-RKN system can provide a molecular basis for understanding plant-nematode interactions.

“…(Manzanilla-López et al, 2002). Similarly, Godínez- Vidal et al (2013) reported that during the compatible Capsicum annuum-N. aberrans interaction, at 7 dpi only 12.3% of the inoculated J 2 were observed inside the roots. The same as in Meloidogyne spp., a certain proportion of individuals that enter the root are different, some are female and others are male; males are vermiform and leave the root, while females become wider Cuadro 1.…”

Nacobbus aberrans sensu lato es uno de los nematodos más importantes en el cultivo de jitomate. Para su manejo, es de importancia el estudio de estrategias sostenibles como la resistencia genética, comúnmente encontrada en parientes silvestres de los cultivos. Al respecto, surgió el interés por conocer la respuesta de poblaciones locales (Michoacán, México) de jitomate silvestre (Solanum lycopersicum var. cerasiforme) a la inoculación con juveniles de segundo estadio de N. aberrans s.l. Se montaron tres experimentos (E1, E2, y E3). Se evaluaron cinco genotipos silvestres y uno cultivado (cv. Río grande). A los 7 y 21 días posteriores a la inoculación (dpi) se evaluó el número de nematodos dentro de la raíz, y a los 45 y 60 dpi el agallamiento de raíces. En E1 y E2, a 7 y 21 dpi se encontraron los estadios J2 y J3-J4. En los tres experimentos ocurrió agallamiento, y a 60 dpi la producción de huevos fue evidente. N. aberrans s.l. invadió las raíces, y completó su desarrollo y reproducción. Estos resultados revelan la aptitud de las cinco poblaciones mexicanas de jitomate silvestre como hospedantes del nematodo, y sugieren la necesidad de explorar otras solanáceas silvestres como posibles fuentes de resistencia al nematodo.

“…Plant sophisticated defense mechanisms include the pathways of phytohormones, salicylic and jasmonic acid, whose genes have been characterized in local and systemic responses in many cultivated species associated with Nacobbus spp. ( Godinez-Vidal et al., 2010 ; Godinez-Vidal et al., 2013 ; Villar-Luna et al., 2015 ; Cabrera-Hidalgo et al., 2021 ).…”

Sustainable strategies for management of the “false root-knot nematode” Nacobbus spp.

The genus Nacobbus, known as the false root-knot nematode, is native to the American continent and comprises polyphagous species adapted to a wide range of climatic conditions. Alone or in combination with other biotic and abiotic factors, Nacobbus spp. can cause significant economic yield losses on main food crops such as potato, sugar beet, tomato, pepper and bean, in South and North America. Although the genus distribution is restricted to the American continent, it has quarantine importance and is subject to international legislation to prevent its spread to other regions, such as the European Union. The management of Nacobbus spp. remains unsatisfactory due to the lack of information related to different aspects of its life cycle, survival stages in the soil and in plant material, a rapid and reliable diagnostic method for its detection and the insufficient source of resistant plant genotypes. Due to the high toxicity of chemical nematicides, the search for alternatives has been intensified. Therefore, this review reports findings on the application of environmentally benign treatments to manage Nacobbus spp. Biological control strategies, such as the use of different organisms (mainly bacteria, fungi and entomopathogenic nematodes) and other eco-compatible approaches (such as metabolites, essential oils, plant extracts, phytohormones and amendments), either alone or as part of a combined control strategy, are discussed. Knowledge of potential sources of resistance for genetic improvement for crops susceptible to Nacobbus spp. are also reported. The sustainable strategies outlined here offer immediate benefits, not only to counter the pathogen, but also as good alternatives to improve crop health and growth.
