[Bacterial plant diseases]
Since TJ Burrill discovered in 1878 that the pathogen of pear scald was a bacterium, numerous bacterial plant diseases have been discovered. Plant pathogenic bacteria belong to one of the following genus: Agrobacterium , Erwinia , Xanthomonas , Pseudomonas , or Corynebacterium. Most of them are rod-shaped bacteria measuring a few micrometers in length and just under 1 micrometer in diameter, and only Corynebacterium is gram-positive and non-flagellated.
