What is an rbcL gene?
The rbcL gene is the barcode DNA for plant species. J.R. Abbott 23676 (FLAS) ribulose-1,5-bisphosphate carboxylase large subunit (rbcL) gene, but phylogenetically the precise position of sample could not found because the limitation of rbcL gene.
What is rbcL and matK?
Among plastid regions, rbcL is the best characterized gene. matK is one of the most rapidly evolving plastid coding regions and it consistently showed high levels of discrimination among angiosperm species (Fig. 1C) (8, 9).
What are rbcL and matK used for?
The matK and rbcL loci are considered standard plant DNA barcoding markers due to their universality, relatively high overall sequence quality, low cost, and high discriminatory power between angiosperms [26,27]. Specifically, rbcL has a higher PCR amplification success, but lower discriminatory power than matK.
Is rbcL a protein?
An rbcL mRNA-binding protein is associated with C3 to C4 evolution and light-induced production of Rubisco in Flaveria. Present address: Cargill, Inc., Fort Collins, CO 80525, USA.
What is the function of rbcL?
| Molecular function | Lyase, Monooxygenase, Oxidoreductase |
|---|---|
| Biological process | Calvin cycle, Carbon dioxide fixation, Photorespiration, Photosynthesis |
| Ligand | Magnesium, Metal-binding |
Why is the rbcL gene used?
Within angiosperms the rbcL gene has been widely sequenced and used for inferring plant phylogenies at higher taxonomic levels. Unfortunately rbcL does not usually contain enough information to resolve relationships between closely related genera, such as Hordeum, Triticum, and Aegilops.
What does rbcL stand for?
RbcL
| Acronym | Definition |
|---|---|
| RbcL | Ribulose Bisphosphate Carboxylase Large (microbiology) |
| RbcL | Road and Bridge Contract Limits |
| RbcL | Red Blood Cell Lysate |
Why is rbcL useful?
The rbcL gene is a useful barcode because it codes for part of the key photosynthesis enzyme ribulose bisphosphate carboxylase (RuBisCo), so it is present in virtually all plant species. One section of its DNA sequence is very variable between species, making it ideal for DNA barcoding.
What is the function of the RbCl gene?
The chloroplast gene rbcL encodes the large subunit of ribulose bisphosphate carboxylase. In Chlamydomonas reinhardtii, this gene is transcribed more actively than any other protein-encoding chloroplast gene studied to date.
What is the function of RbCl?
Is rbcL ionic or covalent?
Thus, in $RbCl$, rubidium forms a cation and chlorine forms an anion and an ionic bond is formed. Whereas, in $BrCl$ , both bromine and chlorine are halogens and tend to gain electrons. So they share an electron and form a covalent bond. Thus, we can say that $RbCl$ is the more ionic compound.
What type of compound is rbcL?
Rubidium chloride
An inorganic chloride composed of rubidium and chloride ions in a 1:1 ratio. Rubidium chloride is the chemical compound with the formula RbCl. This alkali metal halide is composed of rubidium and chlorine, and finds diverse uses ranging from electrochemistry to molecular biology.
Where is the rbcL gene found in plants?
All of these things are made possible by the ability of plants to photosynthesize, which is dependent on the rbcL gene (Freeman, 2008). The rbcL gene is a valuable tool for assessing phylogenetic relationships. This gene is found in the chloroplasts of most photosynthetic organisms.
What is the nucleotide sequence of the rbcL gene?
The symbiont rbcL gene shared the highest degree of nucleotide sequence identity with the cyanobacterium Anabaena (69%) while the rbcS nucleotide sequence shared 61% identity with that of the green alga Chlamydomonas reinhardtii [1].
Is the rbcL gene stable in illuminated cells?
Transcripts of a chimeric rbcL-GUS construct in which the leader sequence of the rbcL gene was replaced by 103 bp of the leader sequence of the atpB gene were stable in illuminated cells [16]. Likewise, interruption of psbB /T and psbH with a strong transcriptional terminator from the rbcL gene does not influence transcript accumulation [17].
How does evolution affect the RBC L gene?
With this in mind, the evolution of organisms could very well affect the ability of scientists to use the rbc L gene as an identification tool due to the fact the gene may change. Freeman, Scott. Biological Science. San Francisco: Pearson/Benjamin Cummings, 2008.
