Differential histopathological response of pepper (Solanaceae) cultivars to Nacobbus celatus (Nematoda) populations
Background and aims: The false-root knot nematode (Nacobbus spp.) comprises polyphagous species, with pepper (Capsicum annuum) being one of the most affected crops. Due to the lack of resistant pepper genotypes, we compared the responses of different commercial cultivars to identify possible plant d...

Background and aims: The false-root knot nematode (Nacobbus spp.) comprises polyphagous species, with pepper (Capsicum annuum) being one of the most affected crops. Due to the lack of resistant pepper genotypes, we compared the responses of different commercial cultivars to identify possible plant defence mechanisms against N. celatus.
M&M: Nematodes from Río Cuarto (Córdoba Province) and Lisandro Olmos (Buenos Aires Province) were inoculated on pepper cultivars: California Wonder (control), Fyuco INTA, Yatasto, and Fenomeno RZ. Plants were grown under a greenhouse and galls were analysed by histopathological techniques.
Results: The roots of the commercial cultivars showed the typical morpho-anatomical alterations induced by N. celatus: gall formation, hyperplasia reactions, development of syncytia in the central cylinder and disorganisation of vascular tissues. Syncytial cells in contact with females of nematodes from Lisandro Olmos showed a defence reaction by Fyuco INTA, whereas feeding sites in Fenomeno RZ did not denote high metabolic activity in nematodes of both origins.
Conclusions: The different responses observed between populations and/or hosts demonstrate the importance of considering nematodes from different geographical origins when testing plant material for tolerance and/or resistance to N. celatus. Studies of this nature are necessary since they facilitate a more in-depth understanding of the parasite-plant interaction. |

Introducción y objetivos: El falso nematodo de la agalla (Nacobbus spp.) comprende especies polífagas, siendo el pimiento (Capsicum annuum) uno de los cultivos más afectados. Debido a la falta de genotipos resistentes del pimiento, comparamos las respuestas de diferentes cultivares comerciales para identificar posibles mecanismos de defensa contra N. celatus. M&M: Nematodos provenientes de Río Cuarto (provincia de Córdoba) y Lisandro Olmos (provincia de Buenos Aires) se inocularon en cultivares de pimiento: California Wonder, Fyuco INTA, Yatasto y Fenomeno RZ. Las plantas se desarrollaron en invernadero y las agallas se analizaron mediante técnicas histopatológicas. Resultados: Las raíces de los cultivares analizados mostraron las alteraciones morfoanatómicas típicas inducidas por N. celatus: formación de agallas, reacciones de hiperplasia, desarrollo de sincitios en el cilindro central y desorganización de los tejidos vasculares. Las células sincitiales en contacto con hembras de Lisandro Olmos mostraron una reacción de defensa por parte de Fyuco INTA, mientras que los sincitios en Fenomeno RZ denotaron baja actividad metabólica en nematodos de ambas procedencias. Conclusiones: Las diferencias observadas entre las poblaciones y/o hospedadores demuestran la importancia de considerar nematodos de diferentes orígenes geográficos al analizar material vegetal para determinar su tolerancia y/o resistencia a N. celatus. Estudios de esta naturaleza son necesarios ya que facilitan una comprensión más profunda de la interacción parásito-planta.
