“…AAL-toxin, thought to be a hostspecific phytotoxin affecting crops, was found to be non-hostspecific due to its phytotoxicity to a wide range of weed species Abbas, Vesonder et al, 1993;Tanaka et al, 1993). Destruxin B (discussed below) was also reported to be host-specific (Bains and Tewari, 1987), but was later found to be non-host-specific (Buchwaldt and Green, 1992).…”

“…Toxins produced by the pathogen are one such factor. To date, A. brassicae is known to produce four destruxins namely, destruxin B, homodestruxin B, destruxin B 2 , and desmethyl-destruxin B (Ayer and Peha-Rodriguez 1987;Bains and Tewari 1987;Buchwaldt and Jensen 1991). Of thèse, destruxin B (Ayer and Peha-Rodriguez 1987;Bains and Tewari 1987;Buchwaldt and Green 1992), destruxin B 2 (Buchwaldt and Green 1992) and homodestruxin B (Buchwaldt and Green 1992;Tewari 1991) are reported to hâve phytotoxic activity.…”

“…Amongthe phytotoxins, only destruxin B has been studied for its host-specificity and its rôle in blackspot pathogenesis (Bains 1989;Bains and Tewari 1987;Buchwaldt and Green 1992). No such detailed information is available for homodestruxin B and destruxin B 2 except that thèse were found to be toxic to the leaves of B. napus at 20.1 x 10 5 mol L 1 , and could hâve phytotoxicities similar to that of destruxin B (Buchwaldt and Green 1992).…”

“…Bains and Tewari (1987) described it as a host-specific toxin, whereas, Buchwaldt and Green (1992) described it as a host-selective toxin and suggested that the discrepancy could be due to différent toxin treatment methods used for host and non-host plants by Bains and Tewari (1987). The discrepancy could also be due to the methods used to monitorthe symptoms caused by the toxin.…”

“…The discrepancy could also be due to the methods used to monitorthe symptoms caused by the toxin. Bains and Tewari (1987) monitored the symptoms visually, whereas, Buchwaldt and Green (1992) used a more sensitive technique and observed symptoms by light microscopy. The technique enabled them to observe symptoms that might not be visible to the naked eye.…”

Homodestruxin B, a compound produced by Alternaria brassicae, the causal organism of the blackspot disease of rapeseed, is known to be phytotoxic to the leaves of Brassica napus. In this study we found that its phytotoxicity was comparable to that of destruxin B, another toxin produced by the pathogen when tested on B. napus. Homodestruxin B caused symptoms of different severities in leaves of various non-host plants. The results suggestthat homodestruxin B is a non-host-specific toxin.

Destruxin A (DA), a cyclodepsipeptidic secondary metabolite of the entomopathogenic fungus, Metarhizium anisopliae, is an important anti-immunity agent against insect hemocytes. To understand the mechanism of the molecular responses to DA, fifth-instar larvae of the silkworm, Bombyx mori, were injected with 2 μg of DA. The proteomics of hemocytes were then investigated using two-dimensional electrophoresis and mass spectrometry, and validated qPCR. As a result, a total of 47 differently expressed protein spots were detected and 22 proteins in 26 spots were identified. There are eight immunity-related proteins, including three downregulated proteins (antitrypsin isoform 3, p50 protein, and calreticulin precursor) and five upregulated proteins (C-type lectin 10 precursor, serine proteinase-like protein, paralytic peptide, PPO-1, and PPO-2). Four resistance- and/or stress-related proteins (arginine kinase, carboxylesterase clade H, member 1, aminoacylase, and thiol peroxiredoxin) were upregulated. Ten proteins with other or unknown functions were also recorded. Five selected proteins were verified with qPCR. These results provide new insights into the molecular mechanism of host immune response to DA challenge.
