Fumonisin- and AAL-Toxin-Induced Disruption of Sphingolipid Metabolism with Accumulation of Free Sphingoid Bases.[Pubmed:12232389]
Plant Physiol. 1994 Nov;106(3):1085-1093.
Fumonisins (FB) and AAL-toxin(include AAL Toxin TC1) are sphingoid-like compounds produced by several species of fungi associated with plant diseases. In animal cells, both fumonisins produced by Fusarium moniliforme and AAL-toxin(include AAL Toxin TC1) produced by Alternaria alternata f. sp. lycopersici inhibit ceramide synthesis, an early biochemical event in the animal diseases associated with consumption of F. moniliforme-contaminated corn. In duckweed (Lemna pausicostata Heglem. 6746), tomato plants (Lycopersicon esculentum Mill), and tobacco callus (Nicotiana tabacum cv Wisconsin), pure FB1 or AAL-toxin(include AAL Toxin TC1) caused a marked elevation of phytosphingosine and sphinganine, sphingoid bases normally present in low concentrations. The relative increases were quite different in the three plant systems. Nonetheless, disruption of sphingolipid metabolism was clearly a common feature in plants exposed to FB1 or AAL-toxin(include AAL Toxin TC1). Resistant varieties of tomato (Asc/Asc) were much less sensitive to toxin-induced increases in free sphinganine. Because free sphingoid bases are precursors to plant "ceramides," their accumulation suggests that the primary biochemical lesion is inhibition of de novo ceramide synthesis and reacylation of free sphingoid bases. Thus, in plants the disease symptoms associated with A. alternata and F. moniliforme infection may be due to disruption of sphingolipid metabolism.
Arabidopsis AAL-toxin-resistant mutant atr1 shows enhanced tolerance to programmed cell death induced by reactive oxygen species.[Pubmed:18725200]
Biochem Biophys Res Commun. 2008 Oct 31;375(4):639-44.
The fungal AAL-toxin(include AAL Toxin TC1) triggers programmed cell death (PCD) through perturbations of sphingolipid metabolism in AAL-toxin-sensitive plants. While Arabidopsis is relatively insensitive to the toxin, the loh2 mutant exhibits increased susceptibility to AAL-toxin(include AAL Toxin TC1) due to the knockout of a gene involved in sphingolipid metabolism. Genetic screening of mutagenized loh2 seeds resulted in the isolation of AAL-toxin-resistant mutant atr1.Atr1 displays a wild type phenotype when grown on soil but it develops less biomass than loh2 on media supplemented with 2% and 3% sucrose. Atr1 was also more tolerant to the reactive oxygen species-generating herbicides aminotriazole (AT) and paraquat. Microarray analyses of atr1 and loh2 under AT-treatment conditions that trigger cell death in loh2 and no visible damage in atr1 revealed genes specifically regulated in atr1 or loh2. In addition, most of the genes strongly downregulated in both mutants were related to cell wall extension and cell growth, consistent with the apparent and similar AT-induced cessation of growth in both mutants. This indicates that two different pathways, a first controlling growth inhibition and a second triggering cell death, are associated with AT-induced oxidative stress.
