“…This result is consistently in all nematode stages as they invade and infect the host tissues and confirms the potential nematicidal effect of water soluble compounds present in S. nigrum extract (Haseeb and Butool 1996;Pestana et al 2014a).…”

Isolation and expression of effector genes encoding proteins secreted by plant-parasitic nematodes into a host can be helpful in improving the understanding of parasitic interactions. In this study, calreticulin, a highly conserved Ca 2+ -binding and multifunctional protein, and beta-1,4-endoglucanase, a cell wall-degrading enzyme, both known to be secreted from oesophageal gland cells and injected through the nematode stylet into host tissue, were analysed. Full-length cDNAs from calreticulin (crt) and beta-1,4-endoglucanase (eng) with an estimated size of 1549 and 1342 bp, respectively, were isolated from the root-lesion nematode Pratylenchus goodeyi (Pg) by RT-PCR and RACE techniques. Pg-crt and Pg-eng cDNAs were characterized in silico, and their expression assessed by semiquantitative PCR in nematodes exposed to a chemical stress provided by a Solanum nigrum extract showing nematicidal activity. It was demonstrated that the plant extract down-regulated the levels of Pg-crt mRNA, whereas the transcripts of Pg-eng mRNA held steady. This extract also affected nematode behaviour towards the roots since the number of nematodes that reached and penetrated the roots diminished when the exposure time rose. These observations indicate that the nematicidal compounds present in the plant extract were effective as a signal to influence the infection success of P. goodeyi in vitro and it might be tested against other phytoparasitic nematodes.

“…Recently, there has been a resurgence of interest in this group of plants, perhaps because the media and governmental agencies have given greater attention to health foods (Foster, 1991). Some herb species are known hosts of phytoparasitic nematodes (Chinappen et al, 1988;Inserra et al, 1989;Mustika, 1992;Rhoades, 1988), and conversely, certain herbs or medicinal plants can control nematodes (Haroon and Huettel, 1991;Haseeb and Butool, 1990;Mukhopadhyaya et al, 1980;Tanda et al, 1989). Information on plants with resistance or tolerance to common plant nematodes is becoming increasingly important, especially for urban gardeners where using pesticides for nematode control is limited or nonexistent.…”

Twenty herb species were exposed to root-knot nematode under greenhouse conditions. The root systems were examined for root gall development and nematode reproduction as an indication of host suitability. The herbs evaluated were balm (Melissa officinalis L.), basil (Ocimum basilicum L.), catnip (Nepeta cataria L.), chamomile (Matricaria recutita L.), coriander (Coriandrum sativium L.), dill (Anethum graveolens L.), fennel (Foeniculum vulgare Mill.), hyssop (Hyssopus officinalis L.), lavender (Lavandula augustifolia Mill.), oregano (Origanum vulgare L.), peppermint (Mentha ×piperita L.), rocket-salad (Erurca vesicaria L.), rosemary (Rosmarinus officinalis L.), rue (Ruta graveolens L.), sage (Salvia officinalis L.), savory (Satureja hortensis L.), sweet marjoram (Origanum majorana L.), tansy (Tanacetum vulgare L.), thyme (Thymus vulgaris L.), and wormwood (Artemisia absinthium L.). Peppermint, oregano, and marjoram consistently were free of root galls after exposure to initial nematode populations of two or 15 eggs/cm3 of soil medium and were considered resistant. All other herb species developed root galls with accompanying egg masses, classifying them as susceptible or hypersusceptible to root-knot nematode. The highest initial nematode egg density (15 eggs/cm3) significantly decreased dry weights of 14 species. The dry weights of other species were unaffected at these infestation densities after 32- to 42-day exposure.
