What is Ricinus communis used for?
communis have been widely used in traditional medicine such as abdominal disorders, arthritis, backache, muscle aches, bilharziasis, chronic backache and sciatica, chronic headache, constipation, expulsion of placenta, gallbladder pain, period pain, menstrual cramps, rheumatism, sleeplessness, and insomnia.
Which part of Ricinus is communis?
Castor oil is a tasteless and odorless vegetable oil that is extracted by pressing of the seeds of the castor plant, scientifically known as Ricinus communis. Castor seeds are rich in triglyceride, which is what makes them so valuable.
Is Ricinus communis invasive?
The volunteer plant in your yard is Ricinus communis, commonly called castor bean. This plant is a native of tropical Africa and has somewhat of a dual personality. On the other hand, it is considered an invasive plant that has become an undesirable weed in Southern and Central California.
What is draft genome sequence?
Draft Genome Sequence. MGI Glossary. Definition. Sequence of genomic DNA having lower accuracy than finished sequence; some segments are missing or in the wrong order or orientation. See also Finished Sequence.
What is meant by Ricinus communis?
Definitions of Ricinus communis. large shrub of tropical Africa and Asia having large palmate leaves and spiny capsules containing seeds that are the source of castor oil and ricin; widely naturalized throughout the tropics. synonyms: castor bean plant, castor-oil plant, palma christ, palma christi.
Is Ricinus communis the same as castor oil?
Ricinus Communis (Castor) Seed Oil is the naming convention for castor oil used in cosmetics. It is produced by cold pressing the seeds and subsequent clarification of the oil by heat.
What is resinous communis?
Ricinus communis, the castor bean or castor oil plant, is a species of perennial flowering plant in the spurge family, Euphorbiaceae. The seed also contains ricin, a water-soluble toxin, which is also present in lower concentrations throughout the plant.
Why are castor beans invasive?
Ecological Effects Castor bean is similar to other invasive species studied along the Santa Clara River. The seeds easily germinate after fires or other land disturbances and displace native vegetation. The ricin in the seeds can cause poisoning in cattle, other animals and humans if ingested or significantly inhaled.
What is the family of castor?
Spurges
Ricinus/Family
Castor-oil plant, (Ricinus communis), also called castor bean, large plant of the spurge family (Euphorbiaceae), grown commercially for the pharmaceutical and industrial uses of its oil and for use in landscaping.
What is a draft and finished genome sequence?
Draft genomes can have segments of contiguous base pairs interspersed with gaps for which the sequence is unknown. So how can a draft genome or for what matters, a pile of sequences become a complete genome? All sequencing technologies give “reads”. These reads are uninterrupted stretches of known DNA sequence.
What is gene splicing called?
In heredity: Transcription. …in a process called intron splicing. Molecular complexes called spliceosomes, which are composed of proteins and RNA, have RNA sequences that are complementary to the junction between introns and adjacent coding regions called exons.
Is Ricinus communis plant poisonous?
Ricin is one of the most poisonous naturally occuring substances known. The seeds from the castor bean plant, Ricinus communis, are poisonous to people, animals and insects. Perhaps just one milligram of ricin can kill an adult. The symptoms of human poisoning begin within a few hours of ingestion.
How is the Ricinus communis genome annotated by NCBI?
The RefSeq genome records for Ricinus communis were annotated by the NCBI Eukaryotic Genome Annotation Pipeline, an automated pipeline that annotates genes, transcripts and proteins on draft and finished genome assemblies.
How big is the ricin gene in castor bean?
Here we report the draft genome sequence of castor bean (4.6-fold coverage), the first for a member of the Euphorbiaceae. Whereas most of the key genes involved in oil synthesis and turnover are single copy, the number of members of the ricin gene family is larger than previously thought.
Where is ricin synthesized in the endoplasmic reticulum?
Ricin is synthesized as a precursor encoding both subunits in the endoplasmic reticulum of endosperm cells and is translocated and accumulated in protein bodies 13. The precursor is proteolytically processed in the endoplasmic reticulum and in the protein bodies, where it is stored as the mature heterodimer.
How is ricin similar to other hemagglutinins?
Ricin is very similar to the R. communis agglutinin (RCA) 14. However, whereas ricin is a weak hemagglutinin, RCA has low toxicity and strong hemagglutinin activity. In addition, RCA is a tetrameric protein composed of two RTA- and two RTB-like subunits.
