The book contains an exposition of more than 30 methods of modern experimental biology, actively used in the study of plants. Methods of genetic engineering and bioinformatics, functional genomics, protein chemistry and histochemistry, methods of studying biologically active compounds and signal transduction, as well as cell biology and analysis of subcellular structures. are considered in detail. A number of methods were developed or modified by the authors of the articles, specialists of the Institute of Plant Physiology and other institutes of the Russian Academy of Sciences. The structure and method of presentation of the material make the task of mastering a method as easy as possible, help to avoid errors during the experiment and correctly interpret the results obtained. Many of the methods described are widely used both in the study of plant objects and objects of other kingdoms of living organisms. This collection will contribute to the competent use of the most modern research methods in the practice of domestic biological science. For students, graduate students, researchers conducting fundamental or applied research in plant biology and agriculture .
