Pseudomonas syringae is a rod-shaped, Gram-negative bacterium with polar flagella.As a plant pathogen, it can infect a wide range of species, and exists as over 50 different pathovars, [2] all of which are available to researchers from international culture collections such as the NCPPB, ICMP, and others.
Xanthomonas actively kill other bacterial using type IV secretion system and defend itself from amoeba using type VI secretion system. [19] [20] [1] To prevent infections, limiting the introduction of the bacteria is key. Some resistant cultivars of certain plant species are available as this may be the most economical means for controlling ...

Bacterial soft rot on taro (Colocasia esculenta) Bacterial soft rots are caused by several types of bacteria, but most commonly by species of gram-negative bacteria, Erwinia, Pectobacterium, and Pseudomonas. It is a destructive disease of fruits, vegetables, and ornamentals found worldwide, and affects genera from nearly all the plant families.
These bacteria are facultative saprophytes, meaning that they are typically parasitic while also having the ability to live on dead or decaying organic matter under the proper conditions. Upon initial infection, the bacteria remain in the epiphytic stage; however, the harmful endophytic stage is reached when the bacteria actually enter the ...
