芽生孢子

真菌无性孢子中叶状孢子的种类
image
芽生孢子指的是芽孢子，属于真菌无性孢子中叶状孢子的一种。由细胞出芽生成，如酵母菌、隐球菌及念珠菌可产生此类孢子。芽生孢子单细胞，形态多变，无侧生分生孢子，关节孢子呈桶状或长方形，末端多圆形，无附着孢。丝孢酵母属有芽生孢子，无环痕孢子，尿素酶阳性，而地霉属无芽生孢子，但可见从关节角部发芽。

简介

即芽孢子。以出芽形式进行营养繁殖所产生的一种孢子。常见于真菌门中的酵母菌。芽生孢子的形成过程是在细胞一定部位的细胞壁向外突出，细胞膜和原生质体也随着向外突出，细胞核分成2个，一个留在母细胞中，一个进入突起中，形成的突起的过程即为出芽。开始阶段芽仍与母体相连通，以后在与母细胞相连处缢断，芽即变成1个孢子，即芽生孢子。芽生孢子从母体上脱离后，直接发育成1个新个体。有时出芽生殖进行得很快，所形成的芽孢子还未从母细胞上脱落，又通过出芽产生出芽孢子，甚至可形成由多个细胞连成的假菌丝.GOOGLE

Namely, Bacillus sub. In the form of vegetative propagation by budding produces a spore. Is common in the door in the yeast fungi. Blastospore process is the formation of certain parts of the cell wall outward prominent cell membrane and also as to the protoplast outside the prominent nuclei were divided into two, a stay in the mother cell, one into the processes in the process of formation processes shall be sprouting. the beginning of bud is still connected with the mother's body pass, after the connected with the mother cell at constriction off, bud that is into a spore, that is, blastospore. blastospore the detachment from the mother, directly develop into a new individual. sometimes budding reproduction is proceeding very quickly, the spores formed by the child has not yet detached from the mother cells, but also through the budding produce budding spores, and even can be formed by a number of cells connected into a pseudo-mycelium.
