柽柳不同生育期可培养内生真菌群落特征
Characteristics of Culturable Endophytic Fungal Communities detected at Different Growing Stages of Tamarix ramosissima
摘要
Abstract
In order to understand the variations of distribution pattern and community composition of fungi at different growth stages of Tamarix ramosissima for clarification of their relationships with each other,genera and species of endophytic fungi present in T.ramosissima at the dormancy,growth and flowering stages were investigated.Morphological and molecular biological studies of the endophytic fungi isolated from different organs of T.ramosissima plant led to obtainment of a total number of 216 fungi strains,identically belonging to a number of 26 genera or 62 species.Comparative and statistical analysis demonstrated an existence of variations on the composition and structure of endophytic fungal community between the different growth stages of plants.The dominant genus of endophytic fungi observed in branches at both dormancy and vegetative growth stages was Alternaria while at the flowering stage that was Botrytis.On the other side,the dominant genus of endophytic fungi in leaves at the growing stage became to be Chaetomium.A.tenuissima and A.alternata were detected at all three stages.Interestingly,it was found that the species diversity in branches was higher than that in leaves at both of the growth and flowering stages.As T.ramosissima changed from dormancy to growth and flowering stage,the number of endophytic fungi species dropped and the content between species and genera changed significantly.关键词
