三孢布拉霉老化性状传递特征初报

DISCOVERY OF SENESCENCE TRANSFERRING IN BLAKESLEA TRISPORA

胡萝卜素产生菌三孢布拉霉（Blakesleatrispora）的老化现象及其特征。其老化菌株通过菌丝接触，将老化性状传递给正常菌株。并通过转变正常菌株的孢子，使老化性状传递给后代。菌丝的老化伴随着体内胡萝卜素的消失。

A senornt strain of the carotene-producing species, Blakeslea trispora, was discovered. The senescence can be transfrred from the senscent strain to the wild strain and by mycelial contact. The senescent process is accompanied by the disappearing of carotene in mycelium.
