The large subunit of ribulose 1,5-bisphosphate carboxylase (rbcL) and the beta subunit of chloroplast ATP synthase (atpB) are encoded by divergently transcribed genes on the plastid genome. We have identified DNA binding factors specific for sequences located in the intergenic region between these two genes. Soluble plastid extracts from pea or whole cell extracts from maize protected a maize c...

A stem-loop region is present at the 3' terminus of the chloroplast rbcL mRNA in all taxa surveyed to date. In spinach, this structure has been shown by others to be involved in modulating transcript stability and correct 3' terminus processing, and is a conserved feature of other flowering plant rbcL mRNAs. In Chlamydomonas reinhardtii, an analogous structure has been shown by others to serve ...

We cloned and sequenced a portion of chloroplast DNA from the hornwort Anthoceros formosae. A nucleotide sequence of 7556 bp contained structures similar to those of ndhK, ndhC, trnV, trnM, atpE, atpB, rbcL, trnR and accD. The arrangement of these was the same as that of other chloroplast DNA. However, two nonsense codons were located within the putative coding region of rbcL, although they wer...

DNA barcode sequences are accumulating in large data sets. A barcode is generally a sequence larger than 1000 base pairs and generates a computational burden. Although the DNA barcode was originally envisioned as straightforward species tags, the identification usage of barcode sequences is rarely emphasized currently. Single-nucleotide polymorphism (SNP) association studies provide us an idea ...

To understand the composition and photosynthetic carbon fixing activities of natural phytoplankton communities, we employed group-specific ribulose bisphosphate carboxylase (RubisCO) large subunit gene probes (rbcL) to examine RubisCO gene expression. The rbcL genes from Synechococcus PCC6301 (cyano) and from Cylindrotheca sp. [chromo) were used as probes at select stations to examine levels of...

Anacardiaceae is well-known for its edible fruits and economically important species in Indonesia. Approximately 3% of Indonesia's endangered vulnerable belong to this family. Fast accurate identification crucial support the conservation efforts family, such as employing DNA sequences. Species using sequences, known barcoding, has been widely used many applied fields. So far, application barcod...

Potassium-free artificial sea water causes a loss of cell potassium and a gain of cell sodium in Porphyra perforata, which is not attributable to an inhibition of respiration. On adding KCl or RbCl to such low potassium, high sodium tissues, net accumulation of potassium or rubidium takes place, accompanied by net extrusion of sodium. Rates of potassium or rubidium accumulation and sodium extru...

this study included 81 samples which belonged to 13 speices from myriophyllum genus. both nrdna its1 and its2 and cpdna matk, rbcl and trnh-psba loci were used for diagnose of invasive from native plant. the nrdna its1and its2 data proved highly variable and could differentiate between all but had low pcr amplification success,based on these result they would not recommend as a suitable barcode...

DNA barcoding is currently gaining popularity due to its simplicity and high accuracy as compared to the complexity and subjective biases associated with morphology-based identification of taxa. The standard chloroplast DNA barcode for land plants recommended by the Consortium for the Barcode of Life (CBOL) plant working group needs to be evaluated for a wide range of plant species. We th...

A cladistic analysis of sequences from the chloroplast gene rbcL was used to determine the systematic affinities of Rhizophoraceae and Anisophylleaceae. This analysis rejects close relationships of Rhizophoraceae with Celastraceae or Elaeocarpaceae, suggested previously, and identifies Erythroxylaceae as sister group within the Malpighiales, supported by several morphological and anatomical cha...
