DDRT PCR PDF

(a) Principle of the reactions underlying DDRT-PCR analysis. (N) Any of the four nucleotides G, A, T, or C. V can be any nucleotide besides T. (B) Any nucleotide. Recently, a new approach has successfully been developed: Differential-Display Reverse Transcription-PCR (DDRT-PCR). This technique has been proven to. Establishment of infection and disease implies modifications in the genetic programmes of the cell systems that are involved and the differential expression of.

The two bacterial strains the endophytic isolate SA and S. Although chloramphenicol showed higher activity than our endophytic isolate; the antagonistic activity of this isolate is more preferred than this antibiotic.

Isolation, gene cloning and expression profile of a pathogen recognition protein: The reasons for this hypothesis came from that there are many recorded disadvantages of chloramphenicol including the risk of its side effects, rising of dert rates and uncomfortable posology Diniz-Santos et al.

However, only one of the sequenced genes was matched with genes deposited in GenBank. The obtained sequence revealed that the concerned gene is serine drrt gene.

The extraction of the active metabolites produced by the endophytic isolate SA was done as follows: Braz J Infect Dis. Gene Ontology GO Terms.

The mixture was filtered using filter papers to remove the agar medium pieces and the ethanolic filtrate was undergoing to GC—MS analysis as described previously Ezhilan and Neelamegam ; Moustafa et al. Earthworm- a potential source for stable and potent antimicrobial compounds- isolation and purification study. Antagonistic effect of endophytic isolate SA against S. The protein is well known as antimicrobial agent and was reported to be produced by plants, animals and insects.

In this study, Bacillus endophyticus strain SA isolated from the inner tissue of the stem of the cultivated plant Salvadora persica, Asir, Kingdom of Saudi Arabia produces an antagonistic factor.

To our knowledge, this is the first study that illustrates the bacterial production of serine protease for antagonistic function against another genus of bacteria.

Endophytes have been defined as microorganisms bacteria or fungi which for all or part of their life cycle reside dsrt the inner parts of plant tissues, but cause no symptoms of disease Vega et al. The Bacillus subtilis genome sequence: Endophytic microbes embody pharmaceutical potential.
