introduction lentil is an important pulse crop in iran. lentil is a seed propagating, self-pollinating crop originating from near east. it is containing 27.5% -31.75% protein and it has high level of iron, calcium, phosphor, thiamin, niacin, and some unusual amino acid as hydroxyarnitin, hydroxyarginin and homo arginin. faostat reported that the world production of lentils was 4,975,621 metric ...

Genetically engineered tomato (Lycopersicon esculentum) with the ability to synthesize glycinebetaine was generated by introducing the codA gene encoding choline oxidase from Arthrobacter globiformis. Integration of the codA gene in transgenic tomato plants was verified by PCR analysis and DNA blot hybridization. Transgenic expression of gene was verified by RT-PCR analysis and RNA blot hybridi...

BACKGROUND In order to understand how biological systems function it is necessary to determine the interactions and associations between proteins. Gene fusion prediction is one approach to detection of such functional relationships. Its use is however known to be problematic in higher eukaryotic genomes due to the presence of large homologous domain families. Here we introduce CODA (Co-Occurren...

Zinc Finger Nucleases (ZFNs) made by Context-Dependent Assembly (CoDA) and Transcription Activator-Like Effector Nucleases (TALENs) provide robust and user-friendly technologies for efficiently inactivating genes in zebrafish. These designer nucleases bind to and cleave DNA at particular target sites, inducing error-prone repair that can result in insertion or deletion mutations. Here, we asses...

Tomato (Lycopersicon esculentum Mill.) plants, which normally do not accumulate glycinebetaine (GB), are susceptible to chilling stress. Exposure to temperatures below 10 degrees C causes various injuries and greatly decreases fruit set in most cultivars. We have transformed tomato (cv. Moneymaker) with a chloroplast-targeted codA gene of Arthrobacter globiformis, which encodes choline oxidase ...

The prodrug activation system formed by the E. coli codA gene encoding cytosine deaminase (CD) and 5-fluorocytosine (5-FC) developed for selective cancer chemotherapy suffers from a sensitivity limitation in many tumour cells. In an attempt to improve the CD/5-FC suicide association, we combined the E. coli upp gene encoding uracil phosphoribosyltransferase (UPRT) with codA gene to create the s...

The use of positive selectable marker genes is widespread in plant genetic transformation allowing transgenic cells to grow while repressing non-transgenic cells. Negative selectable markers, on the contrary, allow the repression or ablation of transgenic cells. The codA gene of Escherichia coli encodes cytosine deaminase that hydrolyzes 5-fluorocytosine (5-FC) into the cytotoxic compound 5 flu...

Gene synthesis is hampered by two obstacles: improper assembly of oligonucleotides; oligonucleotide defects incurred during chemical synthesis. To overcome the first problem, we describe the employment of a Computationally Optimised DNA Assembly (CODA) algorithm that uses the degeneracy of the genetic code to design overlapping oligonucleotides with thermodynamic properties for self-assembly in...

Glottalization of coda /t, p/ is a common process in American English. This study uses acoustic measures to determine when coda glottalization occurs in the conversational speech of the Buckeye Corpus. Vowels preceding coda /t, p/ tokens for 40 speakers were analyzed using H1*–H2*, an acoustic correlate of glottal constriction. Results indicate that coda glottalization is more common before a s...

We developed a counterselectable deletion system for Thermus thermophilus HB27 based on cytosine deaminase (encoded by codA) from Thermaerobacter marianensis DSM 12885 and the sensitivity of T. thermophilus HB27 to the antimetabolite 5-fluorocytosine (5-FC). The deletion vector comprises the pUC18 origin of replication, a thermostable kanamycin resistance marker functional in T. thermophilus HB...
