What was the original name of Xanthomonas juglandis?
In 1905 it was reclassified as Bacterium juglandis, in 1930 it became Phytomas juglandis, and in 1939 it was named Xanthomas juglandis. The International Standards for Naming Pathovars declared it to be named Xanthomonas campestris pv. juglandis in 1980.

What is Xanthomonas campestris?
Xanthomonas campestris is a bacterium that causes a variety of plant diseases, including “black rot” in cruciferous vegetables and bacterial wilt of turfgrass . It is also used in the commercial production of xanthan gum, a high-molecular-weight polysaccharide which has many important uses, especially in the food industry.
What is the disease cycle of Xanthomonas arboricola?
The disease cycle of Xanthomonas arboricola begins on the leaves of the infected plant where the bacteria will live in an epiphytic stage (gathering all nutrients and water from the air) until mid to late spring when sufficient rainsplash spreads the bacteria to new buds and fruits where it becomes pathogenic.
