Temperature is one of the climatic factors that determine the limits of the natural distribution of plants on earth. When the temperature drops below 0oC, it is not possible for physiological events to occur in the plant as the water in the plant freezes. Small ice crystals inside and between cells mix into the cytoplasm during freezing and cause death by disrupting the protoplasmic structure. Bacteria are thought to be one of the factors affecting the freezing event, which is initiated by internal or external nucleators and occurs heterogeneously in nature. These bacteria, which trigger the formation of ice crystals (INA bacteria), especially those belonging to the Pseudomonas syringae species, are thought to significantly restrict the habitats of grapevines and many other woody fruit species. In this review, it was investigated whether there is a relationship between the damage caused by low temperatures during different periods in vineyards and orchards and bacteria. In this direction, the relationships between bacteria species, structures, habitats, seasonal population sizes, mechanisms of action, temperatures triggered by ice crystal formation, cold damage, and supercooling have been examined and tried to be explained in the light of current studies.
