Plastids have evolved from an endosymbiosis between a cyanobacterial symbiont and a eukaryotic host cell. Their division is mediated both by proteins of the host cell and conserved bacterial division proteins. Here, we identified a new component of the plastid division machinery, Arabidopsis thaliana SulA. Disruption of its cyanobacterial homolog (SSulA) in Synechocystis and overexpression of a...
We report here a 100-fold increased frequency of plastid transformation in tobacco by selection for a chimeric aadA gene encoding aminoglycoside 3"-adenylyltransferase, as compared with that obtained with mutant 16S rRNA genes. Expression of aadA confers resistance to spectinomycin and streptomycin. In transforming plasmid pZS197, a chimeric aadA is cloned between rbcL and open reading frame OR...
The plastid genome of higher plants contains more than one hundred genes for photosynthesis, gene expression, and other processes. Plastid transcription is done by two types of RNA polymerase, PEP and NEP. PEP is a eubacteria-type RNA polymerase that is essential for chloroplast development. In Arabidopsis thaliana, six sigma factors (SIG1-6) are encoded by the nuclear genome, and postulated to...
background genetic manipulation of chloroplast in higher plants offers a number of unique prerogatives, including; undesirable of pleiotropic genome and gene silencing effects and also use as an important agronomic trait for producing essential biomaterials and industrial enzymes. in order to manipulate chloroplast genome, specific vectors are required. these vectors can be transformed and expr...
Unlike many other photosynthetic dinoflagellates, whose plastids contain a characteristic carotenoid peridinin, members of the genus Lepidodinium are the only known dinoflagellate species possessing green alga-derived plastids. However, the precise origin of Lepidodinium plastids has hitherto remained uncertain. In this study, we completely sequenced the plastid genome of Lepidodinium chloropho...
Nucleus-encoded plastid-targeted proteins of photosynthetic organisms are generally equipped with an N-terminal presequence required for crossing the plastid membranes. The acquisition of these presequences played a fundamental role in the establishment of plastids. Here, we report a unique case of two non-homologous proteins possessing completely identical presequences consisting of a bipartit...
Identification of all the protein components of a plastid (chloroplast) ribosomal 30 S subunit has been achieved, using two-dimensional gel electropholesis, high performance liquid chromatography purification, N-terminal sequencing, polymerase chain reaction-based screening of cDNA library, nucleotide sequencing, and mass spectrometry (electrospray ionization, matrix-assisted laser desorption/i...
Quantitative real-time PCR (qRT-PCR) is a powerful technique for measuring and evaluating gene expressions during different biological processes. To facilitate gene expression studies, normalization with respect to stable housekeeping genes (HKGs) is mandatory. T he western flower thrips, Frankliniella occidentalis (Thysanoptera: Thripidae), the main vector of Tomato spotted wilt virus (TSWV), ...
Members of the Aedes genus of mosquitoes are widely recognized as vectors of viral diseases. Ae.albopictus is its most invasive species, and are known to carry viruses such as Dengue, Chikugunya and Zika. Its emerging importance puts Ae.albopictus on the forefront of genetic interaction and evolution studies. However, a panel of suitable reference genes specific for this insect is as of now und...
