Genus species

Description and significance

Infected plants have leaves and fruits with brown colored lesions surrounded by oily, water soaked yellow rings. These lesions may in time fall out creating a sharp hole in the leaves. This bacteria may be found in any or all different types of citrus. These include oranges, grapefruits, limes, lemons, etc.

Genome structure

Chromosome is circular (5,175,554 bp) as well as the plasmids (33,700 bp and 64,920 bp). This bacteria is gram negative and "produces slow growing, non-mucoid colonies in culture, ecologically obligate plant parasite".

Cell structure and metabolism

Flagella is present and interacts through plant pathogen. 2 membranes are present and no inteins.


This bacteria occurs in agricultural and urban areas. It generally affects citrus trees in high temperature areas, heavy rainfalls, and high winds. Due to wind and rainfall, this bacteria may spread throughout situated areas. It is most likely to infect plants in high temperature and heavy rainfall weather. This causes citrus canker, which may progressively and ultimately lead to economic losses on citrus industries.


This bacteria contaminates citrus plants that prevents progressive fruit and health production. It diminishes fruit production of trees, ultimately leading to no fruits and death of plant. This disease may contaminate plants and even equipments.
