Brassicaceae

Introduction The Brassica rapa, is a member of the Brassicaceae (cabbage/mustard) family. This species is an herbaceous annual or biennial field mustard. Europe is thought to be the origin of the species. However, many variations, including turnips, bok choi, and cabbage are known to have advanced in areas of Asia. B. rapa has now been introduced to natural and artificial habitats throughout the world via commercial cultivation and personal gardening. B. rapa presents significant phenotypic diversity. Generally speaking, this species has flat roots, large soft-hairy leaves, and small yellow flowers. (Lauffer B., Lauffer, D., Williams, P., 2012) B. rapa are rapid-cycling plants known as fast plants. William H. Paul developed these fast plants…

Brassica rapa, better known as the Brassica campestris, which is part of the mustard family. It is originated from Europe, but is now found all around the world (Courteau, 2012). This plant can grow anywhere between 30 to 120 centimeters tall. The growth of a plant is controlled by the hormone of the plant. The hormone will send a chemical signal to the plant which allows it to grow. An example of a plant’s hormone is called gibberellin. Gibberellin (GA) is responsible for the growth and the…

nutrients, etc.). Garlic mustard is a good example of an invasive plant. Originally brought over from Europe to North America by early European settlers, the herb was used as food and a substitute for garlic, medicinally to treat gangrene and ulcers, and has also been used as a form of erosion control. The first record of garlic mustard in the United States was in Long Island, New York in 1868. In Europe, there are insects and herbivores that have used the plant as a source of food, but the…

Flea beetles are pest of brassicaes, creating holes in the leaves and stems of seedlings. The seedlings are highly attacked as soon as they surface above the ground level and the damage of these beetles are very pronounced on young plants and even cause plant death. Some flea beetles are general feeders, others attack only particular types of plant. The flea beetle has a narrow host range to plants primarily in the brassicaceae. Most of the flea beetles prefer cruciferous plants which produce…

study with the researcher from OSU? It also helps if the writer gives a little background about lncRNA. Also, there is no quantitative evidence in the article that can make logical-type of person not trust the article. Numerical data is also important to give a scale for readers. Overall, the main idea of the article is good and provide sufficient data. 4. Where could you go to find out more information about this topic? How does this study fit into the entire body of evidence on the topic?…

Introduction: Brassica Rapa comes from the family of Brassicaceae, also known as the mustard family; the genus Brassica L is known as mustard, and the species Brassica Rapa L is commonly known as field mustard (Plant Profile). There are several subspecies of Brassica Rapa, like a turnip, and they all have varying uses like oil and root production. We are using the Wisconsin Fast Plants that have artificially selected to be optimal for educational use. We are trying to increase the number of…

prevent pollen contamination. The resulting seeds were germinated on moist filter paper and mature progeny were genotyped as above for different variants. With reference to Brown’s paper Yau-Wen Yang et al. said that in mammals, the rate of silent nucleotide substitution in mitochondrial DNA (mtDNA) is very high compared to that in nuclear DNA (Brown et al. 1979). In contrast, to that the rate is low in plant mtDNA, only about one-third of the silent rate in chloroplast DNA and one-twelfth of…

The fungus Bipolaris sorokiniana has a wide host range and observed on cereals, barley, rice, rye, wheat etc. and many non-cereal grasses across the world (Jones 1983). Forty-five plant genera that include Asteraceae, Brassicaceae, Lineace and Solanaceae were reported to be prone to this pathogen including Poae, Asteraceae, Brassicaceae, Linaceae and Solanaceae (Harding 1979 ). 1.3.2.3. Symptoms of common root rot (CRR) Because of the difficulty to diagnose the disease as the above ground…

Leroy et al. (2000) used 4 microsatellite primers to characterise Brassica oleracea accessions. Among the 136 reproducible fragments generated, 25 (18.4%) fragments were common for all Brassica, 27 (19.9%) were unique and 84 (61.7%) were phylogenetically informative. Flannery et al. (2006) assessed polymorphisms in Brassica, Arabidopsis, Camelina, Raphanus and Sinapis using 10 plastid SSR primer sets. Eight loci were polymorphic, and separated the individuals of Brassicaceae into taxon-specific…
