In this study, studies were carried out to take into solution the element rubidium (Rb), which is in complex ore structure of Na + K feldspar, pyroxene and alumina silicate, an environmentally sensitive manner with high efficiency. Malatya - Kuluncak was used study. first stage roasting method tried obtain chloride (RbCl) or sulphate (Rb2SO4) structures, are water-soluble forms sodium-potassium...

Two new species, Machilus bokorensis Yahara & Tagane and Machilus brevipaniculata Yahara & Tagane (Lauraceae) are described from Bokor National Park, Cambodia with their illustrations and DNA barcodes of the two plastid regions of rbcL and matK and the nuclear region of ITS.

Plastomic replacement of the tobacco (Nicotiana tabacum) Rubisco large subunit gene (rbcL) with that from sunflower (Helianthus annuus; rbcL(S)) produced tobacco(Rst) transformants that produced a hybrid Rubisco consisting of sunflower large and tobacco small subunits (L(s)S(t)). The tobacco(Rst) plants required CO(2) (0.5% v/v) supplementation to grow autotrophically from seed despite the subs...

When plastids are transferred between eukaryote lineages through series of endosymbiosis, their environment changes dramatically. Comparison of dinoflagellate plastids that originated from different algal groups has revealed convergent evolution, suggesting that the host environment mainly influences the evolution of the newly acquired organelle. Recently the genome from the anomalously pigment...

The systematic utility of sequences from a non-coding region of chloroplast DNA (cpDNA) between psbA and trnH (6v6) was examined by assessing phylogenetic relationships in subtribe Sonchinae (Asteraceae: Lactuceae). Primers constructed against highly conserved regions of tRNA genes were used for PCR amplification and sequencing. The psbA-trnH intergenic spacer contains several insertions and de...
