The "triangle of U" diagram, showing the genetic relationships among six species of the genus Brassica. Chromosomes from each of the genomes A, B and C are represented by different colours. The triangle of U (/ uː / OO) is a theory about the evolution and relationships among the six most commonly known members of the plant genus Brassica.
Wisconsin Fast Plants were initially developed as part of a larger breeding project of Rapid-Cycling Brassicas, originating in the early 1970s. [1] Wisconsin Fast Plants and other Rapid-Cycling Brassicas were selected through conventional plant breeding to be a tool that would speed up genetic research for disease resistance in economically important Brassica crops.

The genus Brassica is known for its important agricultural and horticultural crops and also includes a number of weeds, both of wild taxa and escapees from cultivation. Brassica species and varieties commonly used for food include bok choy , broccoli , cauliflower , cabbage , choy sum , kohlrabi , napa cabbage , rutabaga , turnip and some seeds ...
Xanthomonas campestris pv. raphani is a gram-negative, obligate aerobic bacterium that like many other Xanthomonas spp. bacteria has been found associated with plants. This organism is closely related with Xanthomonas campestris pv. campestris, but causes a non-vascular leaf spot disease that is clearly distinct from black rot of brassicas.
The mustard plant is any one of several plant species in the genera Brassica, Rhamphospermum and Sinapis in the family Brassicaceae (the mustard family). Mustard seed is used as a spice. Grinding and mixing the seeds with water, vinegar, or other liquids creates the yellow condiment known as prepared mustard.
Black rot, caused by the bacterium Xanthomonas campestris pv. campestris (Xcc), is considered the most important and most destructive disease of crucifers, infecting all cultivated varieties of brassicas worldwide. [1] [2] This disease was first described by botanist and entomologist Harrison Garman in Lexington, Kentucky, US in 1889. [3]
In Scottish and some other English dialects, the word turnip can also refer to rutabagas (North American English), also known as swedes in England, a variety of Brassica napus, which is a hybrid between the turnip, Brassica rapa, and the cabbage. Turnips are generally smaller with white flesh, while rutabagas are larger with yellow flesh.
Xanthomonas (from greek: xanthos – "yellow"; monas – "entity") is a genus of bacteria, many of which cause plant diseases. [1] There are at least 27 plant associated Xanthomonas spp., that all together infect at least 400 plant species. Different species typically have specific host and/or tissue range and colonization strategies. [1]
