Is Brassica rapa an invasive species?

It is sometimes grown in rotation as a cool season crop, as a green manure, or for grazing. It is also used for phytoremediation in some circumstances. The same vigorous habits that make it useful and easy to study in experiments can make it a difficult plant to control. It can become an invasive weed.

What is the common name of Brassica rapa?

Brassica rapa is a diverse wild plant species known with several common names: wild turnip, field mustard, turnip mustard, wild mustard, wild kale or bird rape. It has bright yellow flowers which attract bees. Brassica rapa has several subspecies with different uses as crop plants. Turnip (Brassica rapa subsp.

Are turnips part of the Brassica family?

turnip, (Brassica rapa, variety rapa), also known as white turnip, hardy biennial plant in the mustard family (Brassicaceae), cultivated for its fleshy roots and tender growing tops. The roots are also cooked and served whole or mashed and are used in stews.

What is in the Brassicaceae family?

The Brassicaceae family includes broccoli, Brussels sprouts, cauliflower, kale, mustard (greens), and collards. Collectively, these crops are referred to as cole crops or crucifers.

Why is B Rapa a model organism?

rapa can be used as a relevant model organism for teaching human genetics because they share two important features with humans: 1) they do not self-pollinate, and 2) they are genetically diverse. Self-incompatibility also preserves genetic diversity within B. rapa strains.

Who developed Brassica rapa?

Dr. Paul H. Williams
The Wisconsin Fast PlantTM is a trademark name for a species of plant called Brassica rapa. Dr. Paul H. Williams, plant pathologist at the University of Wisconsin at Madison, spent 15 years developing rapid-cycling versions of six species of Brassica.

What family is Brassica rapa in?

B1.0 General Description and Use as a Crop Brassica rapa L. belongs to the Cruciferae (Brassicaceae) family, also known as the mustard family. The name crucifer comes from the shape of flowers, with four diagonally opposite petals in the form of a cross.

What is the difference between B rapa and B campestris?

Part B The Biology of Brassica rapa Brassica rapa and B. campestris were first described as two species by Linnaeus, with B. rapa being the turnip form and B. campestris the wild weedy form. Metzger in 1833 concluded that these were the same species and combined the taxa under the name B. rapa (Toxeopus et al., 1984).

Should we give subspecies names to the different forms of B rapa?

Scientists are still unsure as to whether to give subspecies names to each of the forms of B. rapa. Because the cultivars (cultivated varieties) of various forms can be crossed so easily, many intermediate forms are being produced by plant breeders.

How can we improve the genome assembly of B rapa?

Over the last few years, the genome assembly of B. rapa(version 3.0) has been improved using single-molecule sequencing, optical mapping, and chromosome conformation capture technologies (Hi-C), resulting in an approximately 30-fold improvement with a contig N50 size of 1.45 Mb compared with that of previous references (Zhang et al., 2018).
