Nthesize them de novo, so thethe nematodes readily absorb sterols.By way of example, Meloidogyne arenaria, M. incognita, and Pratilenchus agilis incorporate and transform sterols Meloidogyne arenaria, M. incognita, and Pratilenchus agilis incorporate and transform sterols into necessary derivatives in their development and reproduction [56]. As a result, nematodes really should into needed derivatives in their growth and reproduction [56]. Therefore, nematodes must elicit a biological response to some sterols. Also, plant ematode interactions need elicit a biological response to some sterols. Also, plant ematode interactions need flaflavonoids and may be required for nematode reproduction. Nevertheless, some flavonoids vonoids and could be required for nematode reproduction. Having said that, some flavonoids with particular Bax Inhibitor site structural arrangements have shown toxic effects on particular targets including with particular structural arrangements have shown toxic effects on distinct targets such as enzymes. Ultimately, thiophenes could inhibit enzymes like superoxide dismutase [57] and enzymes. Lastly, thiophenes could inhibit enzymes like superoxide dismutase [57] and damage DNA [58]. The transformation of secondary metabolites to much more toxic compounds harm DNA [58]. The transformation of secondary metabolites to much more toxic compounds also happened with PAs, as pointed out ahead of. also happened with PAs, as talked about before.three.
