Opis:
The interaction of endophytic microorganisms with plants are a common occurrence that brings mutual benefits to partners. Plants are the main habitat of bacteria that live inside their tissues and do not cause disease symptoms, but affect the growth and development of plants by producing substances that promote their development. Research on the diversity of endophytic bacteria associated with forest trees is insufficient – little is known about the diversity of endophytic bacteria, and especially their function in tree tissues. Bacteria positively affecting the host tree, among others, increase biomass growth by supporting tree health. The species diversity of endophytic bacteria in plants is influenced by the plant genotype, tissue type, development phase and environmental conditions. So far, bacteria that develop in root, stem, and leaf tissues have been best known. Among the forest trees in which the occurrence and diversity of endophytic bacteria have been studied, there are species such as pine, spruce, birch and oak. The presented paper is a review of the latest literature on the subject.

Opis:
Bark beetles (order Coleoptera, family Scolitydae) comprise a taxonomic group of species that look similar although they differ widely in their ecology and biochemical adaptations to host tees. This diversity of bark beetle biology in which each species is adapted to only one or a few host species, has probably resulted from natural selection due to the great variety of trees and their biochemicals. It also is likely that each species of tree has coevolved various chemicals to defend against the herbivorous selection pressures of bark beetles and other insects. Host plant chemicals can be attractive, repellent, toxic or nutritious to bark beetles and have effects on: (1) finding and accepting the host tree (host selection and suitability), (2) feeding stimulation and deterrence, (3) host resistance, (4) pheromone/allomone biosynthesis and communication, and (5) attraction of predators, parasites and competitors of bark beetles. There are two theories on how bark beetles find suitable host trees. The first is that they locate such trees by orienting over several metres to volatile chemicals usually released by damaged or diseased trees (called "primary attraction"). The second theory is that beetles fly about and encounter suitable host trees at random, whereupon they land and test them by short−range olfaction or gestation.
