P. syringae can cause water to freeze at temperatures as high as −1.8 °C (28.8 °F), [26] but strains causing ice nucleation at lower temperatures (down to −8 °C (18 °F)) are more common. [27] The freezing causes injuries in the epithelia and makes the nutrients in the underlying plant tissues available to the bacteria.
Halo blight seems to thrive when the temperatures are cooler. The optimal temperature for Pseudomonas Syringae to thrive is 20-23 °C. Moist environments also allow the spread of this disease. The pathogen enters the plant through wounds or stomata and hydathodes during periods of high relative humidity or free moisture.
Pseudomonas syringae pv glycinea should be monitored carefully in seed production fields as it is seed borne and can affect seed quality. [2] A study conducted by Stefani et al. in 1998 found that seeds with contamination levels ranging from 0.5 to 20% did not lead to any significant yield loss when grown in warm and dry regions. [3]
Pseudomonas is a genus of Gram-negative bacteria belonging to the family Pseudomonadaceae in the class Gammaproteobacteria.The 348 members of the genus [2] [3] demonstrate a great deal of metabolic diversity and consequently are able to colonize a wide range of niches. [4]
A spectrum of hemibiotrophic plant pathogens, including the bacterium Pseudomonas syringae and the oomycete Phytophthora infestans (potato blight), also exhibit characteristics of both biotrophs and necrotrophs and thus are called hemibiotrophs, depending on the stages of their life cycle.

Ice-minus bacteria is a common name given to a variant of the common bacterium Pseudomonas syringae (P. syringae).This strain of P. syringae lacks the ability to produce a certain surface protein, usually found on wild-type P. syringae.
Pseudomonas syringae pv. Aesculi is a bacterium that causes bleeding canker of horse chestnut. The pathogen overwinters in the soil and can survive in the soil for about a year. [2] It is spread by water, rain, and tools that were used on the infected tree. [3] It causes lesions on the bark of the tree that can be near the base of the trunk or ...
Pseudomonas infection refers to a disease caused by one of the species of the genus Pseudomonas. P. aeruginosa is a germ found in the environment and it is an opportunistic human pathogen most commonly infecting immunocompromised patients, such as those with cancer , diabetes , cystic fibrosis , [ 1 ] severe burns, AIDS , [ 2 ] or people who ...
