What is the matK gene?
Maturase K (matK) is a plant plastidial gene. The protein it encodes is an organelle intron maturase, a protein that splices Group II introns. It is essential for in vivo splicing of Group II introns.
Where is the matK gene?
chloroplast
The matK gene of chloroplast is 1500 bp long, located within the intron of the trnK and codes for maturase like protein, which is involved in Group II intron splicing.
How many amino acids are in matK?
The ORF alignment included representatives from all major intron subgroups and included sequence from RT domains 5–7 and X, again with unalignable positions excluded, for a final data set of 143 amino acids. Phylogenetic analyses indi- cated that matK ORFS fall within the ML (mitochondrial- like) class of introns (fig.
What is the molecular weight of Maturase K?
The ~65 kDa mass matched the predicted mass for MatK based on amino acid sequence when expressed using the R1 initiation codon.
What is trnH psbA gene?
Barcode trnH-psbA makes for a good candidate for large-scale DNA barcoding of forage legumes and some grasses, such as C. cristatus, D. glomerata and T. flavescens (Table 3). However, further work is needed to produce reference sequences in more forage species and cultivars.
What is its region in fungi?
The ITS region is the most widely sequenced DNA region in molecular ecology of fungi and has been recommended as the universal fungal barcode sequence. It has typically been most useful for molecular systematics at the species to genus level, and even within species (e.g., to identify geographic races).
What is the function of tRNA?
transfer RNA / tRNA Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein. tRNAs function at specific sites in the ribosome during translation, which is a process that synthesizes a protein from an mRNA molecule.
Why was 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.
