| Abstract: | "'Mushroom alcohol,' or 1-octen-3-ol, is a common fungal volatile organic compound (VOC) that has been studied for its flavor properties, its effects on fungal spore germination, mushroom development, and as a signaling agent for insects. Far less is known about its effects on plants. We exposed Arabidopsis thaliana seeds, under conditions conducive to germination, to high (10 and 100 mg/1) and low concentrations (1, 2, and 3 mg/1) of racemic, S, and R forms of 1-octen-3-ol for 3 days. In addition, 1-, 2-, 3-, and 4-week-old A.thaliana plants also were exposed to 1 mg/1 of the compounds for the same period of time. Seedling formation was retarded with all tested levels of exposure to 1-octen-3-ol for both enantiomers and the racemer, while 95% of unexposed control seeds germinated to seedling within 3 days. There was a dose-dependent response in the reduction of seedling formation between 1 mg/1 and 3 mg/1 of exposure. When exposed seeds were removed from the VOC, nearly all resumed germination. Young plants exposed to 1 mg/1 of the R and S enantiomers of 1-octen-3-ol exhibited a mild inhibition of growth and chlorophyll production at 2 and 3 weeks but not at 4 weeks" |
