[Abstract]  In order to quantify P accumulation and P efflux in the ectomycorrhizal basidiomycete fungus Hebeloma cylindrosporum, we supplied 32P to mycelia previously grown in vitro in liquid medium. The culture had four main steps that are 1) growing the mycelium on complete medium with P, 2) transfer the mycelia into new culture solution with or without P, 3) adding a solution containing 32P and 4) rinsing the mycelia before incubation with or without plant. The main point is to rinse very carefully the mycelia after 32P supply in order to avoid overestimation of 32P efflux into the medium. [摘要]  为了量化外生菌根担囊菌真菌Hebeloma cylindrosporum中的P积累和P流出,我们向以前在体外生长的菌液提供了 32 P 中。 培养物有四个主要步骤:1)在具有P的完全培养基上培养菌丝体,2)将菌丝体转移到具有或不具有P的新培养溶液中,3)加入含有32和32的溶液 )在与或不与植物孵育之前冲洗菌丝体。 要点是在 32 P供应之后非常仔细地冲洗菌丝体,以避免过高估计P P。
【背景】众所周知,菌根真菌和植物之间的关联改善了宿主植物的P营养(由Smith和Read,2008; Plassard和Dell,2010; Cairney,2011; Smith等人,2015)。这种积极的作用主要是由于真菌细胞探索远离根部的土壤的磷酸盐(Pi)吸收,允许探索大量的土壤超过主要吸收根部周围形成的耗尽区(Smith and Read,2008; Cairney,2011; Smith ,2015)。然而,为了受益于宿主植物,吸收的Pi必须从探测土壤的真菌细胞转移到与宿主细胞紧密接触的细胞中。在外生菌根共生中,这些交流被认为发生在外生菌根内的“Hartig网”领域(Smith and Read,2008; ...
