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 ...
Typical floral diagram of a Brassicaceae (Erysimum "Bowles' Mauve") Flowers may be arranged in racemes, panicles, or corymbs, with pedicels sometimes in the axil of a bract, and few species have flowers that sit individually on flower stems that spring from the axils of rosette leaves. The orientation of the pedicels when fruits are ripe varies ...
Tatsoi (Brassica rapa subsp. narinosa [1] or Brassica rapa var. rosularis [2]) is an Asian variety of Brassica rapa grown for greens. Also called tat choy, it is closely related to the more familiar bok choy. This plant has become popular in North American cuisine as well and is now grown throughout the world.
The turnip or white turnip (Brassica rapa subsp. rapa) is a root vegetable commonly grown in temperate climates worldwide for its white, fleshy taproot.Small, tender varieties are grown for human consumption, while larger varieties are grown as feed for livestock.
The isolates can be differentiated into races based on the reaction of several Brassica lines after inoculation. A race structure including 5 races (0 to 4) was first proposed in 1992; [ 12 ] a revised classification model with 6 races was proposed in 2001 [ 13 ] and, more recently, the model was expanded to include nine races.
Xanthomonas campestris is commonly used industrially to produce a water-soluble exo-polysaccharide, known as xanthan gum, from fermentation of carbon sources like glucose. [5] In this process, a preserved culture of the gram-negative bacterium is expanded through growth and then used as an inoculum in bioreactors with liquid growth media .
