Embodiment Construction

[0022] Isolation of plant tapetum tissue is one of the necessary prerequisites for studying the specific expression and regulation of genes related to microspore development, pollen and stigma recognition in the tapetum. By applying the method of the present invention, we have obtained a sufficient amount of plant tapetum tissue with less impurities, laying the foundation for carrying out related research. The establishment of our related methods also fills in related gaps.

Abstract

The invention relates to a method for separating and purifying a plant tapetum tissue, and belongs to the fields of developmental biology and cell biology. The method comprises the steps of collection of anthers, preparation of a cleaning liquid, preparation of an enzymolysis liquid, pretreatment of the anthers, removal of anther microspores, and separation and collection of tapetum cells. Suitable enzyme species and concentration are used for enzymolysis separation of a tapetum tissue, and then the tapetum is collected through filtration, centrifugation and purification. The method has the advantages of simple steps, convenient operation, shorter consumed time and the like, the separation efficiency is good, and the obtained tapetum tissue can be used for subsequent experiments.

Description

technical field [0001] The invention relates to a method for separating tapetum tissue from plant anthers, relates to the separation and acquisition of tapetum tissue, and belongs to the fields of developmental biology and cell biology. Background technique [0002] Tapetal cells exist in the inner side of plant anthers, provide the necessary nutrients for the development of microspores, and degrade after the microspores mature. The tapetum is involved in many physiological processes such as microspore development, pollen and stigma recognition, and is the focus of research in developmental biology and other related research fields. [0003] At present, it is an international research trend to study the specific expression of related genes in tissues. However, the tapetum exists inside the anther, and to carry out relevant research, it is first necessary to separate the tapetum tissue, and no relevant technology has been seen so far. In order to solve the above problems, w...
