Turnip (Brassica rapa) - Wikipedia, the free encyclopedia rapa) is a root vegetable commonly grown in temperate climates worldwide for its white, bulbous taproot. The turnip discussed here, a variety of Brassica rapa, is not the same plant as the rutabaga, though confusion occurs because of regional variations in usage: both may be referred to as "turnip" (see disambiguation page). Varieties of Brassica rapa that have been developed specifically for use as leaf vegetables are called Chinese cabbage. en.wikipedia.org /wiki/Turnip_(brassica_rapa)   (1253 words)

Brassica Breeding and Research - Areas of Interest Brassica is a genus within the Brassicaceae (Cruciferae), commonly known as the mustard family. Brassica napus, is thought to exist primarily through a natural cross between close relatives, the parents, B. oleracea (Cabbage, Kale, Cauliflower, Broccoli) X B. Brassica juncea: The center of origin is believed to be in Central Asia-Himalayas, with migration to secondary centers in India, China and the Caucasus (mountainous region of south-central Russia). www.ag.uidaho.edu /brassica/area_of_interest.htm   (1197 words)

Last check: 2007-09-21) Studies on the effects of space flight factors on integral processes of plant growth and development require an investigation of phytohormones - compounds that affect cellular, tissue-specific and organismal interactions which are necessary for triggering and controlling the physiological and morphological programs. Research object - AstroPlants Brassica rapa L. grown in soil culture on earth for 9 and 15 days and for 9 days in microgravity condition (on the space shuttle Columbia STS-87, 1997).The phytohormones were investigated by HPLC, bioassay and MS/MS spectrometry.

Brassica rapa, is a biennial (life cycle completion is within two seasons) cool season crop, and is one of the most commonly grown and widely adapted root crops today. www.uga.edu /vegetable/turnip.html   (2287 words)

Brassica rapa - Wikipedia, the free encyclopedia Brassica rapa is a plant species widely distributed through temperate climates as a weed, and widely cultivated as a leaf vegetable, a root vegetable, and an oilseed. Bred for over 30 years at the University of Wisconsin by Professor Paul H. Williams, they require little more attention than continuous fluorescent light, water, and fertilizer. Students use these "fast plants" to conduct basic biology experiments, as the Bassica rapa grows quickly, maturing in about 30 days. en.wikipedia.org /wiki/Brassica_rapa   (133 words)

[No title] Because the ingredients for Downy Care were unlisted, the effects of the fabric softener were tested on Brassica rapa, and the expectation was that addition of fabric softener to the soil might enhance growth of B. Five seeds of the Brassica rapa plant were used in each treatment canister using an artificial soil mix containing 50% growth media and 50% vermiculite. The NAR reduced mostly due to the reduced RGR, but because of the reduced NAR, concentrations of nutrients in the plant tissues, such as potassium and calcium were decreased and concentrations of sodium, magnesium, and chlorine were all increased (He and Cramer 1993). w3.uwyo.edu /~dwwilson/downy3.htm   (1326 words)

Brassicas Genome Mapping Projects - North America In Brassica, populations have been prepared and polymorphisms are being identified for mapping genes responsible for the amplification of the inflorescence of Brassica oleracea cv. In agreement with previous findings in other BRASSICA species, 40% of the sequences mapped were duplicated in B. These were either scattered throughout the genome, organized in tandem or in blocks of duplicated loci conserved in more than one linkage group. Although the BRASSICA genomes seems to originate from an ancestral genome of fewer chromosomes, the cultivated genomes are not the result of the reiteration of one or more ancestral chromosomes. www.nal.usda.gov /pgdic/Map_proj/brassica.html   (5367 words)

Carolina Biological: Carolina Tips: Hairy's Inheritance (page 2 of 3) Another example of selective breeding is Brassica rapa, a close relative of turnip, Chinese cabbage, and pak choi. B. rapa has been selected for traits that make it convenient to study, including a short life cycle with rapid flowering time and seed maturation, petite plant form, an ability to grow under continuous fluorescent light and to produce large amounts of seed, and an absence of seed dormancy. Because of their short life cycle, the B. rapa plants used in Wisconsin Fast Plants™ programs are well suited for both plant research and classroom education; they provide ideal tools for investigating the concepts of variation, selection, and evolution. www.carolina.com /tips/99mar/tips399b.asp?print=yes   (600 words)

About BrassicaDB Three sets of genetic maps are available for Brassica napus (one based on publicly available Microsatellite markers, integrated with a framework of RFLP markers whose sequences are now also in the public domain), four sets for Brassica oleracea and one set for Brassica rapa. A list of protein sequences from Brassica napus, Brassica oleracea and Brassica rapa is included in the database, and links to protein databases are provided. As the number of brassica species in the database increases, each new genome will be integrated into this scheme, allowing easy visulisation of cross genome homologies as well. brassica.bbsrc.ac.uk /BrassicaDB/about.html   (551 words)
