Promoters play important roles in gene expression and function. There are three basic types of promoters: Constitutive, specific, and inducible. Constitutive promoters are widely used in genetic engineering, but these promoters have limitations. Inducible promoters are activated by specific inducers.

Recently, an integrated DNA walking strategy has been proposed to prove the presence of GMO via the characterisation of sequences of interest, including their transgene flanking regions and the unnatural associations of elements in their transgenic cassettes.

Most genetically modified (GM) plants contain a promoter, P35S, from the plant virus, Cauliflower mosaic virus (CaMV), and many have a terminator, TNOS, derived from the bacterium, Agrobacterium tumefaciens. Assays designed to detect GM plants often target the P35S and/or TNOS DNA sequences.

Identification of vacuolar Na+/H+ antiporters facilitates the basis of salt stress tolerance mechanisms. Na+ accumulation into the vacuole is crucial for the avoidance of cytoplasmic Na+ toxicity. In this study, we show that the introduction of AtNHX1 into tobacco generated more tolerant plants when compared to wild-type plants.

Tobacco pathogenesis-related protein 1a (PR-1a) is induced in plants during the hypersensitive response (HR) after exposure of plants to salicylic acid (SA) and by develop-mental cues.Gene activation by these diverse stimuli is mediated via anas-1-like element in the PR-1aupstream region.To further analyze the significance of thiscis-acting sequence, an authentic as-1element from the cauliflower mosaic virus 35S RNA promoter was inserted into the PR-1apromoter in place of theas-1-like motif.

Hầu hết virus thực vật có genome RNA, tuy nhiên 2 nhóm virus thực vật được nghiên cứu nhiều nhất có chứa genome DNA: Cauliflower mosaic virus (CaMV) và gemini virus. - Các virus RNA Phần lớn virus thực vật có bộ gene RNA sợi đơn mạch (+) và nhiều dạng có capsid hình que, các protein capsomer hình xoắn. + Tobacco mosaic virus (TMV) Genome TMV là RNA sợi đơn. Genome của chúng mã hoá ít nhất 4 chuỗi polypeptid. Protein 130 và 180 kDal được dịch mã trực tiếp từ cùng một codon bắt đầu trên RNA bộ...
