ФОРМИРОВАНИЕ КОМПЬЮТЕРНОЙ ПОИСКОВОЙ БАЗЫ ДАННЫХ ПО ДИАГНОСТИКЕ ВОЗБУДИТЕЛЕЙ ЧЕРНОЙ НОЖКИ КАРТОФЕЛЯ (РОД PECTOBACTERIUM)

Abstract

Over the last quarter of century, about 10 new species (varieties) of pectolytic bacteria of the genus Pectobacterium, which cause approximately similar symptoms and are quite common in Western European countries and on other continents, have been added to well-known causative agents of black leg of plants and soft rot of tubers of potato for more than a century. In connection with the importation of seed material, most of these new biological objects were identified in the central regions of the European part of the Russian Federation and are beginning to expand actively their range. The accumulated scientific material of research in the country and abroad on pathogens of the genus Pectobacterium is quite voluminous and requires detailed systematization for their accurate monitoring. The article briefly describes the changes in the systematic position of species of this genus over the past 70 years. The collected material in the form of a computer database, which includes up to 40 indicators for each bioobject, will allow you to successfully navigate through specially created information retrieval system. It describes the symptomatic features of the disease depending on the soil and climatic fluctuations of the growing season, the quality of the seed tubers, the indirect impact of the anthropogenic factor, etc. The required parameters of the pathogen will include a detailed description, synonyms and systematic position, the full scope of comparative information on biological properties, diagnostic methods both in pure culture and in the affected material, as well as measures of control with this bioobject. In view of the simplicity of the computer database can be used by the specialists of plant protection, agronomists, plant growers, farmers, as well as employees of research institutes and institutions of agricultural profile.
