“…Another promising research direction is the induction of systemic resistance in host plants. There are many studies on the possible induction of systemic resistance by abiotic agents, such as BTH (benzo[1,2,3]thiadiazole-7-carbothioic acid S-methyl ester) and its derivatives, BABA (β-aminobutyric acid) or MeJa (methyl jasmonate) (Frąckowiak et al 2019;Fujimoto et al 2011;Mutar and Fattah 2013;Veronico et al 2018) as well as by microorganisms such as bacteria or fungi (El-Fattah and Sikora 2007; Siddiqui and Shaukat 2004;Vos et al 2013). This topic, however, still has great investigation potential in nematode studies.…”

Background Root-knot nematodes (RKNs)-Meloidogyne spp.are a group of nematodes distributed worldwide that infect monocotyledonous and dicotyledonous crop species. Plant responses to RKNs have been described in many studies of various host plants. In the course of parasitism, RKNs induce the transcriptional reprogramming of host cells to establish giant cells. Nematode attack induces many mechanisms in host plants, including pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI) and effectortriggered immunity (ETI). Research on plant-RKN interactions has shown the activation and suppression of the expression of genes encoding various defenserelated proteins. Scope and conclusions In this review, our goal is to critically summarize current knowledge on monocotyledonous and dicotyledonous plant-Meloidogyne interactions, including data on the role of RKN effectors and nematode PAMPs in host plant defense responses.

“…Lignin contributes to the protection of plants from physical and chemical stresses, including pathogen challenges. Several studies have revealed that lignification can affect parasitic nematode infection rates [18][19][20][21] . Galls during early stages were subjected to phloroglucinol-HCl staining to detect lignin, which was weakly stained in 3 dpi galls but became more prominent in 5 dpi galls in WT (Fig.…”

Plant materials and growth conditions. All Arabidopsis thaliana plants used in this study are of the Col-0 ecotype background. The mutant line, del1-1, was obtained from the Arabidopsis Biological Resource Center (ABRC). Arabidopsis seeds were stratified for 2 days in 4 °C in the dark, then allowed to germinate and grown for 5 days on 0.25 × Murashige and Skoog (MS) salt mixture (Sigma), 0.5% (w/v) sucrose, and 0.6% (w/v) gellan gum at pH 6.4 under continuous light at 23 °C.

“…incognita invasion the plant defense mechanisms are activated [10]. The plant cell wall plays a fundamental role in this process [11,12]. Plant cell walls differentiate from the primary walls of growing cells to the secondary walls, deposited after the end of cell expansion, which gradually thicken.…”

Meloidogyne incognita is a root knot nematode (RKN) species which is among the most notoriously unmanageable crop pests with a wide host range. It inhabits plants and induces unique feeding site structures within host roots, known as giant cells (GCs). The cell walls of the GCs undergo the process of both thickening and loosening to allow expansion and finally support nutrient uptake by the nematode. In this study, a comparative in situ analysis of cell wall polysaccharides in the GCs of wild-type Col-0 and the microtubule-defective fra2 katanin mutant, both infected with M. incognita has been carried out. The fra2 mutant had an increased infection rate. Moreover, fra2 roots exhibited a differential pectin and hemicellulose distribution when compared to Col-0 probably mirroring the fra2 root developmental defects. Features of fra2 GC walls include the presence of high-esterified pectic homogalacturonan and pectic arabinan, possibly to compensate for the reduced levels of callose, which was omnipresent in GCs of Col-0. Katanin severing of microtubules seems important in plant defense against M. incognita, with the nematode, however, to be nonchalant about this “katanin deficiency” and eventually induce the necessary GC cell wall modifications to establish a feeding site.
