dc.descriptionInfection by the root-knot nematode (RKN), Meloidogyne incognita, impacts crop productivity worldwide, including parsley cultures (Petroselinum crispum). Meloidogyne infection involves a complex relationship between the pathogen and the host plant tissues, leading to the formation of galls and feeding sites that disorganize the vascular system, affecting the development of cultures. Herein, we sought to evaluate the impact of RKN on the agronomic traits, histology, and cell wall components of parsley, with emphasis on giant cell formation. The study consisted of two treatments: (i) control, where 50 individuals of parsley grew without M. incognita inoculation; and (ii) inoculated plants, where 50 individuals were exposed to juveniles (J2) of M. incognita. Meloidogyne incognita infection affected the development of parsley, reducing the growth of some agronomical characteristics such as root weight and shoot weight and height. Giant cell formation was noticed at 18 days after inoculation, promoting disorganization of the vascular system. Epitopes of HGs detected in giant cells reveal the continuous capacity of giant cells to elongate under the stimulus of RKN, essential processes for feeding site establishment. In addition, the detection of epitopes of HGs with low and high methyl-esterified groups indicates the PMEs activity despite biotic stress.
