“…In addition, application of either NO scavenger or a mammalian NOS inhibitor affected appressorial lobe formation (Prats et al, 2008). NO has a regulatory effect on trap formation of nematode trapping fungi Drechslerella stenobrocha by acting contrary to abscisic acid (Xu et al, 2010).…”

SUMMARYAn explosion of research in plant nitric oxide (NO) biology during the last two decades has revealed that NO is a key signal involved in plant development, abiotic stress responses and plant immunity. During the course of evolutionary changes, microorganisms parasitizing plants have developed highly effective offensive strategies, in which NO also seems to be implicated. NO production has been demonstrated in several plant pathogens, including fungi, but the origin of NO seems to be as puzzling as in plants. So far, published studies have been spread over multiple species of pathogenic microorganisms in various developmental stages; however, the data clearly indicate that pathogen-derived NO is an important regulatory molecule involved not only in developmental processes, but also in pathogen virulence and its survival in the host. This review also focuses on the search for potential mechanisms by which pathogens convert NO messages into a physiological response or detoxify both endo-and exogenous NO. Finally, taking into account the data available from model bacteria and yeast, a basic draft for the mode of NO action in phytopathogenic microorganisms is proposed.

“…These studies evaluated different species of nematode-trapping fungi such as Arthrobotrys oligospora, Monacrosporium cytosporum, Arthrobotrys conoides, Drechslerella stenobrocha and D. flagrans, as well as other fungi that do not have nematode trapping activity, but which have been well studied for the production of chlamydospores such as Giberella zeae, Pochonia sp. and Candida albicans [16][17][18][19][20].…”

Resistance structures such as chlamydospores produced by the fungus Duddingtonia flagrans allow the reduction of infectious larvae from gastrointestinal nematodes. The objective of this research was to study the effect of carbon and nitrogen sources on the production of chlamydospores of the fungus in a solid state fermentation system (SSF). Twelve substances were studied using a statistical strategy, evaluating their effect on the production of Chlamydospores Finally, using an optimization strategy, the modifications of the substances that favor the production of chlamydospores were defined, and the effect of these on the predatory capacity of the fungus was evaluated. Optimal conditions were the variability of 0.25% w / w ammonium sulfate and 0.56% w / w sodium acetate in broken rice. The maximum concentration reached under this condition was 2.27x107 chlamydospores g of dry substrate-1, with a productivity of 1.62x106 chlamydospores g of dry substrate-1 day-1.

For example, the average number of traps per colony and the percentage of captured nematodes ( C. elegans ) were greatly increased by addition of ABA to CMA, and the results showed that 100 µM ABA was highly effective at enhancing trap formation of D. stenobrocha (Xu et al ., ). Recently, an evolutionarily highly conserved family of small molecules (ascarosides) was identified in nematodes; they can induce trap formation in all adhesive‐network‐producing species which are phylogenetically closely related to A. oligospora , such as Arthrobotrys musiformis , Arthrobotrys javanica and Dactylella gampsospora , but not in the other species which are more distantly related and produce morphologically different traps (Hsueh et al ., ).…”

“…Abscisic acid (ABA), ascarosides, and other substances (see Table 1) are also effective to induce trap formation (e.g. Balan & Lechevalier, 1972;Cayrol et al, 1984;Kaplan, Davis & Walter, 1991;Persmark & Nordbring-Hertz, 1997;Xu et al, 2011).

Nematode-trapping fungi (NTF) are potential biological control agents against plant- and animal-parasitic nematodes. These fungi produce diverse trapping devices (traps) to capture, kill, and digest nematodes as food sources. Most NTF can live as both saprophytes and parasites. Traps are not only the weapons that NTF use to capture and infect nematodes, but also an important indicator of their switch from a saprophytic to a predacious lifestyle. Formation of traps and their numbers are closely related to the nematicidal activity of NTF, so the mechanisms governing trap formation have become a focus of research on NTF. Recently, much progress has been made in our understanding of trap formation, evolution, and the genome, proteome and transcriptome of NTF. Here we provide a comprehensive overview of recent advances in research on traps of NTF. Various inducers of trap formation, trap development, structural properties and evolution of traps are summarized and discussed. We specifically discuss the latest studies of NTF based on genomic, proteomic and transcriptomic analyses.
