title: Characteristics of defective phage particles of Pectobacterium carotovorum ZM1.
abstract: It is shown for the first time that the expression products of defective prophages are typical of defective lysogenic systems of phytopathogenic Pectobacterium carotovorum. It is established that virus-like particles (LP) such as phage capsids are packing bacterial DNA which size is determined by pulse field gel electrophoresis separation. Based on data about capsid structures which are formed by the virulent mutant ZF40/421, there is made a suggestion about the forming mechanism of defective virions of P carotovorum.
