Application
Driselase from Basidiomycetes has been used in a study to assess the digestion by fungal glycanases of arabinoxylans with different feruloylated side-chains. Driselase from Basidiomycetes has also been used in a study to investigate the purification, characterization, and mode of action of a rhamnogalacturonan hydrolase.
The enzyme from Sigma has been used as a control while testing the ability of p-coumaroyl esterase to release p-coumaroyl and feruloyl groups from intact cell walls.[2]It has also been used in the protoplast preparation from mycelia during a study to investigate the pathogenicity of Cochliobolus carbonum on Maize.[1]
Biochem/physiol Actions
Driselase is a cell wall degrading enzyme that contains cellulase, hemicellulase, pectinase etc. Therefore, it is very effective in removing plant cell walls to make protoplasts.[3]

文献和实验生殖不发达或不发生。其无性孢子因种而异,有的经菌丝体断裂形成粉孢子,有的形成分生孢子或夏孢子(如锈菌目),有的进行芽殖(如黑粉菌目有的种)。有性生殖经双核菌丝进一步发育为担子,双核在担子内经核配和减数分裂形成担孢子。担孢子通常4个,着生在孢子梗上,为单倍体。担子有棒状、管状、球形,担子菌担孢子形成过程示意图分隔或不分隔,散生或聚集在担子果(子实体)上。担子果由双核菌丝组成,也有多种类型。担子及担子果的特征均为分类的依据。根据担子果的有无及类型,将担子菌亚门分为冬孢菌纲、层菌纲及腹菌纲。冬孢菌纲不产生担子
,形成一种特殊的结构,叫锁状连合(下图),在锁状连合的过程中,细胞内二核经过一系列的变化由分裂到融合,形成一个二倍体(2n)的核,此核经二次分裂,其中一次为减数分裂,于是产生4个单倍体(n)子核。这时顶端细胞膨大成为担子,担子上生出4个小梗,于是4个小核分别各移入小梗内,共发育成4个孢子——担孢子。产生担孢子的复杂结构的菌丝体叫做担子果(basidiocarp),就是担子菌的子实体。其形态、大小,颜色各不相同,如伞状、扇状、球状、头状、笔状等。现代分类学将担子菌亚门分为4个纲,即层菌纲(Hymeno
