Introduction Olive, or scientific name Olea europaea L which belongs to Oleacea family is a valuable plant species where it can produce oil and table olives. Gene at certain tissue in species will be expressed where cDNA are sequenced to produce expressed sequence tag (EST) library. EST database is beneficial as it allows new gene discovery, marker discovery, gene mapping, and functional studies to be carried out. This research has contributed EST library of 2304 clone sequences from the young olive leaf and 1536 clone sequences from the immature olive fruit for Turkish olive cultivar Gemlik. Good quality ESTs are used to further analysed by using Phred-Phrap and Contig Assembly Program 3 (CAP3) software. They were then submitted to …show more content…
EST sequences with vector sequence were edited using Phrap “cross-match” application. Contig Assembly Program 3 (Cap3) was used to assemble the sequences obtained from sequencing for analysis while Consed/Autofinish software was used to control the sequence assembly. All sequences were assembled separately into contigs. BLAST of sequences was conducted to determine the gene homology in order to connect their functions. Unique sequences were analysed for biological characteristics as well as functional annotation using program BLAST2GO. New genes can then be identified eventually. Results Two cDNA libraries were established from olive leaf and fruit, with 2304 clones and 1536 clones respectively. A total of 3840 EST sequences was generated from the two cDNA libraries. 106 low-quality EST sequences were removed by using Phred software. 3734 EST sequences with vector sequence were edited using Phrap “cross-match” application. EST sequences and 1506 high quality fruit EST sequences were assembled using Contig Assembly Program 3 (Cap3) to assemble the sequences separately into contigs. Consequently, homolog genes which were consensus EST sequences in GenBank can then be obtained. 2228 leaf EST sequences were assembled into 205 contigs, length ranged from 514 bases to 1924 bases. 1506 fruit EST sequences were assembled into 69 contigs, length ranged from 461 bases to 1909 bases. The two libraries were then assembled to obtain 299
The vital components and techniques of gene cloning are as follows, the DNA sequence that contains the desired gene (EZH2) is amplified by Polymerase chain reaction. PCR was established by Kary Mullis in 1985, popularly known to amplify target sequences of DNA (EZH2) to a billion fold in several hours using thermophilic polymerases (Taq) ,primers and other cofactors (Sambrook and Russell, 2001). Three crucial steps are involved which are Denaturation (at 95°), Annealing of the forward and reverse primers (55-65°) and lastly primer extension (at 72°). After amplification the desired sequence is integrated into the circular vector (pbluescript) forming the recombinant molecule. For the compatibility of the insert and vector, both were digested with (EcoR1) so the same cohesive ends are generated in both, making it easier to ligate. EcoR1 is a restriction enzyme that belongs to the type II endonuclease class which cuts within dsDNA at its recognition site “GAATTC” (Clark 2010; Sambrook and Russell, 2001).
This however, was unsuccessful, as the restriction digestion created fragments of many different lengths, resulting in smears at different lengths on the gel electrophoresis due to the restriction enzyme recognition sites being present in-between the telomeric repeat sequences, the analysis was thus
The Basic Local Alignment Search Tool (BLAST) was the final portion of this lab report. BLAST is provided courtesy of the National Center for Biotechnology Information (NCBI). After running the five chosen tests, students were given the two 16S rRNA sequences that were associated with their assigned culture. The BLAST results served to confirm or disprove the hypothesis of what the unknown may be. The BLAST program compared the given 16S rRNA sequence to a database of known sequences and searched for similarity. (10) This search tool is capable of comparing nucleotide or protein sequences to find statistical significance between the matches. A perfect match to the unknown sequence is indicated by a
It is of great interest to see how far the scientific community has come across with identifying the genes and functions of each encoding protein. The science brought different interventions, as each gene has the possibility of interaction and the whole cellular environment has a type of role to engage in the complex day to day regulation of our eukaryotic cells.
350 of each sample are loaded on the gel. Based on Genomic Solutions, once fixing the changes of fresh 40% methanol and 10% glacial acetic acid for every 12 hour each, the gels were stained for 12 hours with Sypro Ruby solution in the dark. The gels were incubated in 10% methanol: 6% acetic acid for 4 hours for destaining procedure. The gels are the imaged by using ProPick Workstation. Triangulation and robotic excision are conducted for identification of protein spots. It was then submitted to tandem mass spectrometric analysis.
Several approaches can be envisaged to address the function of a gene. The techniques of molecular biology and biochemistry allowing for example to localize the expression of a gene or its product (Northern, western, in situ hybridization, immunofluorescence, etc.), to determine the structure of the protein (NMR, crystallography ...) or to find partners proteins (double hybrid, immunoprecipitation ...) give important information on the function of a gene (V Ecochard -2011).
Many species’ genes have not been sequenced, there could be multiple matches found once more species are added to the genomic database.
All DNA tests were changed in accordance with 100 ng/μl. A 1000 ng (1 μl) aliquot of every example's DNA was utilized for a 50 μl PCR response. The 16S all inclusive eubac-terial preliminaries 530F (5'- GTG CCA GCM GCN GCG G) and 1100R (5'- GGG TTN CGN TCG TTG) were utilized for increasing the 600 bp area of 16S rRNA qualities. HotStar Taq Plus Master Mix Kit (QIAGEN Inc.) was utilized for PCR under the accompanying condi-tions: 94°C for 3 min took after by 32 cycles of 94°C for 30 sec; 60°C for 40 sec and 72°C for 1 min; and a last prolongation venture at 72°C for 5 min. A second-ary PCR was performed for FLX (Roche, Nutley, NJ) amplicon sequencing under the same condition by using designed special fusion primers with differ-ent tag sequences: LinkerA-Tags-530F and LinkerB-1100R. The resultant individual sample after parsing the tags into individual FASTA files was assembled using CAP3. The ace files generated by CAP3 were then processed to generate a secondary FASTA file containing the tentative consensus (TC) sequences of the assembly along with the number of reads in-tegrated into each consensus. The TC was required to have at least a 3-fold coverage. The resulting TC FASTA for each sample was then evaluated using BLASTn (Altschul et al., 1990) against a custom data-base derived from the RDP-II database (Cole et al., 2005) and GenBank website (http://www.ncbi.nlm. nih.gov/). The sequences contained within the
The chemical and reagents used for the extraction and quantitation of DNA were: Plant DNAzol (0.3ml/0.1g), 100% ethanol (100%: 0.225 ml/0.1 g, 75%: 0.3 ml/0.1 g), Chloroform (0.3 ml/0.1 g), Plant DNAzol-ethanol solution: Plant DNAzol, 100% ethanol (1:0.75 v/v), TE buffer (10 mM Tris, 1 mM EDTA pH 8.0), 1.2% agarose gel (Agarose, 1X TAE buffer), 6X loading buffer (glycerol, Tris/EDTA pH 8.0, ethidium bromide), .25X TAE buffer, Restriction enzymes and Restriction endonuclease buffers. All the chemicals used were quality grade. The restriction
Here I cloned and sequenced genes in B. napus homologous to genes in Arabidopsis thaliana. I developed molecular markers from these gene sequences which in addition to other marker systems (including inter simple sequence repeats, intron length polymorphism) were used in molecular characterization of more than 150 canola genotypes.
Part one of this lab consisted of the extraction of onion DNA utilizing a lysis solution. In part two a chain of plastic links was used to mimic the slicing and separating a strand of DNA as restriction enzymes and gel electrophoresis would. In part three, multiple samples of real DNA were compared to each other
The purpose of the Bioinformatics/Molecular Evolution lab is to explore a particular protein given to us by its amino acid sequence. By entering this protein into the Entrez Protein Database in the National Center for Biotechnology Information, and using tools within this database such as Jpred, SMART, and Protoparm, the given protein could be fully analyzed. This experiment was very successful as our particular protein could be identified, and the tools within the NCBI database allowed us to fully analyze both chemical and physical aspects of this protein.
The regulation of gibberellin biosynthesis by both internal and environmental factors is an important part in controlling plant morphogenesis. Due to recent improvements in molecular
There are some regulatory sequences such as enhancers, silencers, insulators, and cis-elements at the proximal and distal regions of the promoter that are involved in the regulation of gene expression at the transcriptional level (Hernandez-Garcia and Finer 2014). The expression of α-amylase genes in both rice cell suspension and germinating embryos is inhibited by sugars and the mechanism involves transcriptional regulation (Lu, Lim et al. 1998). Scanning the
A mechanism of modification is by altering the genome of a type of plant to engineer improved plant strains. In some cases, these modifications are being done to an already successful product, such as wine. This is seen in production of various and new types of wine being produced from the new grape varieties created using CRISPR. Given that grapes are very underrepresented in research, this research has provided new information on the genomes of grapes. This is also important research, because wine is a commercial good found all throughout the world, so this research can be utilized to improve wine production in many places in the world. (1). The use of CRISPR in wine production includes CRISPR technology using the target genes from the
