Autotoxicity of Mycelial Growth in Continuous Cropping Obstacles of Morchella spp.
摘要
Abstract
Autotoxic effect of Morchella mycelia may be a reason for continuous Morchella spp.cropping obstacles.Using M.sextelata strain YMe151 as the experimental material,the autotoxicity of culture medium containing M.sextelata mycelium fermentation broth,or M.sextelata cultivation soil extract,or M.sextelata fruiting body water extract on mycelial growth of M.sextelata was studied.Differential metabolites between continuous Morchella cropping soil and non-continuous Morchella cropping soil were analyzed.The results showed that the mycelial growth rate and biomass of YMe151 decreased when the contents of Morchella fermentation broth,M.sextelata cultivation soil extract and fruiting body water extract were high in the culture medium.Compared with the soil without continuous Morchella cropping,there were 12 differential metabolites in the soil of continuous Morchella cropping.Among these differential metabolites,the abundance of β-L-dioxolane-cytidine,dopamine quinone,alcophosphamide,13-L-hydroperoxylinoleic acid,(8 s,9 s,10 s and 11 s,13,14,17 r)-1 1-dihydroxy-17 in 2-(2-hydroxyacetyl)-10,13-dimethyl-9-nonyl-1-1,2,6,7,8,11,12,14,15,16-decahydrocyclopenta(a)phenanthren-3-one,and palmitoleamide increased,and the abundance of isoferulic acid,a-methylene-y-butyrolactone,4-O-methyl-12-O-tetradecanoylphorbol 13-acetate,N,N-dimethyldodecylamine-N-oxide,sphinganine and 10,20-dihydroxyeicosanoic acid decreased.The results provided a reference for deep understanding of the mechanisms and the subsequent prevention and control of continuous Morchella spp.cropping obstacles.关键词
