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...
The chloroplast gene rbcL encodes the large subunit of ribulose bisphosphate carboxylase. In Chlamydomonas reinhardtii, this gene is transcribed more actively than any other protein-encoding chloroplast gene studied to date. To delineate the rbcL gene promoter, chimeric reporter genes containing fragments of the 5' region of the rbcL gene fused to the coding sequence of the bacterial uidA gene,...
Spinach Rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase) large (rbcL) and small (rbcS) subunits were separated by SDS-PAGE, and protein amount and purity were determined by Bradford assay. Polyclonal antibodies against rbcL and rbcS subunit were generated in female BALB/c mice and had no cross-reaction with each other. A total of 81 microg antigens were used and 0.3 ml anti-sera with t...
Rubisco gene expression was examined in detail in rice (Oryza sativa L.) leaves at different positions, i.e. expanding, mature, and senescent leaves. Rubisco small subunit (RBCS) synthesis and RBCS mRNA levels were maximal in expanding leaves and gradually became lower in mature and senescent leaves, with declines in those of the large subunit (RBCL) being relatively slower. The amount of synth...
Targeted gene replacement in plastids was used to explore whether the rbcL gene that codes for the large subunit of ribulose-1, 5-bisphosphate carboxylase/oxygenase, the key enzyme of photosynthetic CO2 fixation, might be replaced with altered forms of the gene. Tobacco (Nicotiana tabacum) plants were transformed with plastid DNA that contained the rbcL gene from either sunflower (Helianthus an...
Small regulatory RNAs (sRNAs) function as transcriptional and post-transcriptional regulators of gene expression in organisms from all domains of life. Cyanobacteria are thought to have developed a complex RNA-based regulatory mechanism. In the current study, by genome-wide analysis of differentially expressed small RNAs in Synechocystis sp. PCC 6803 under high light conditions, we discovered a...
Although transcription termination is essential to generate functional RNAs, its underlying molecular mechanisms are still poorly understood in plastids of vascular plants. Here, we show that the RNA binding protein RHON1 participates in transcriptional termination of rbcL (encoding large subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase) in Arabidopsis thaliana. Inactivation of RHON1 ...
Increasing water temperatures because of climate change resulted in population shifts and physiological responses aquatic environments. In this study, short-term high-temperature condition effects on green algae Chlorella vulgaris were investigated at transcriptional levels. The photosystem II D1 protein (psbA) gene, a large unit Rubisco (rbcL) gene chloroplastic ascorbate peroxidase (cAPX) exp...
In the cyanobacterial RuBisCO operon from Thermosynechococcus elongatus the rbcX gene is juxtaposed and cotranscribed with the rbcL and rbcS genes which encode large and small RuBisCO subunits, respectively. It has been suggested that the rbcX position is not random and that the RbcX protein could be a chaperone for RuBisCO. In this study, the RbcX protein from T. elongatus was overexpressed, p...
We propose a re ective object-oriented concurrent language RbCl which has no run-time kernel. That is to say, all the behavior of RbCl except for what is restricted by the operating system and hardware can be modi ed/extended by the user. RbCl runs e ciently in a distributed environment and is intended for practical use. The execution of an RbCl program is performed by a metasystem that consist...
