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 does rbcL gene do?
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.
Why is rbcL used for DNA barcoding?
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 rbcL marker?
The rbcL marker based method was adopted to identify green isolates from monospecies but non-axenic cultures of microalgae with 18S universal markers as control. In present study, authors have developed and validated a novel method for molecular identification of microalgae even from non- axenic cultures.
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 |
What genome is rbcL part of?
chloroplast genome
RbcL gene is located in the large single copy region of chloroplast genome [43, 44].
Is RbcL ionic or molecular?
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.
What loci are commonly used for plant DNA barcoding?
A number of loci from the plastid genome, including rbcL, rpoB, rpoC1, trnH-psbA spacer and matK, have been tested for DNA barcoding of plants with different degrees of success [5,20-32].
How long is rbcL sequence?
around 2500 bp
Full-length rbcL sequences are around 2500 bp in length and only represent a small portion of the sequences in our database.
What is RbCl made of?
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.
Is RbCl ionic or molecular?
Do primers (matK+rbcL) show homology and divergence of amplified sequences?
Biological sequence homology and divergence of amplified sequences was studied using Basic Local Alignment Tool (BLAST). Results: Both primers (matk+rbcl) showed good amplification in three species. The sequenced regions reveled conserved genome information for future identification of different medicinal plants belonging to these species.
What is the difference between the universal primer rbcL and matK?
The universal primer rbcl has high universality but low resolution whereas matK offers low universality but high resolution among different species. A combination of both markers matK+rbcl can help to discriminate maximum number of species.
Can rbcL+matK be used to detect adulteration of medicinal material?
The recommended pair combination of rbcL+matK discriminate about 90% of flowering plants (CBOL 5), however, more conserved genomic regions could be identified and used to detect adulteration of medicinal material.
How to perform PCR based amplification of barcoding regions using PCR?
PCR based amplification of barcoding regions was performed using 96-well thermal cycler (Applied Biosystems) and the profile was adjusted to 35 cycles as follows: 94°C for 30 seconds, followed by annealing at 54°C for 45 seconds, and then by extension at 72°C for 45 seconds. After 35 cycles, the profile was linked on hold at 4°C.
