New World tetraploid cottons (Gossypium spp.) originated through hybridization of ancestral diploid species that presently have allopatric ranges in Asia-Africa (the A genome) and the New World tropics and subtropics (the D genome). Despite intensive study, the identity of the parental diploids and the antiquity of polyploidization remain unresolved. In this study, variation in the maternally i...
Transformation of chloroplast ribosomal RNA (rRNA) genes in Chlamydomonas has been achieved by the biolistic process using cloned chloroplast DNA fragments carrying mutations that confer antibiotic resistance. The sites of exchange employed during the integration of the donor DNA into the recipient genome have been localized using a combination of antibiotic resistance mutations in the 16S and ...
BACKGROUND Chloroplast genomes supply valuable genetic information for evolutionary and functional studies in plants. The past five years have witnessed a dramatic increase in the number of completely sequenced chloroplast genomes with the application of second-generation sequencing technology in plastid genome sequencing projects. However, cost-effective high-throughput chloroplast DNA (cpDNA)...
Chlorophylls (Chls) play pivotal roles in energy absorption and transduction and also in charge separation in reaction centers in all photosynthetic organisms. In Chl biosynthesis steps, only a step for the enzymatic reduction of protochlorophyllide (Pchlide) to chlorophyllide (Chlide) is mediated by both nuclear- and chloroplast-encoded genes in land plants. Many plants encode the genes for li...
DNA barcoding is a simple method for the identification of any species using a short genetic sequence from a standard genome section. The present study aimed at examining the nuclear and chloroplast diversity as well as the phylogenetic relationships of eight species of saffron including four spring-flowering and five autumn-flowering species from different parts of Iran, using the nuclear barc...
Rice is the most important crop in the world as the staple food for over half of the population. The wild species of Oryza represent an enormous gene pool for genetic improvement of rice cultivars. Accurate and rapid identification of these species is critical for effective utilization of the wild rice germplasm. In this study, we developed valuable chloroplast molecular markers by comparing th...
Cotton (Gossypium spp.) is commonly grouped into eight diploid genomic groups, designated A-G and K, and one tetraploid genomic group, namely AD. To gain insight into the phylogeny of Gossypium and molecular evolution of the chloroplast genome duringdiversification, chloroplast genomes (cpDNA) from 6 D-genome and 2 G-genome species of Gossypium (G. armourianum D2-1, G. harknessii D2-2, G. david...
