In this work we study the effect of some electrical prosperities on synthetic rubber reinforced with carbon black diluted in heptanes with concentrations from 0.2% gm/mole to 2.0% gm/ mole in temperatures range (100, 150, 200, 250, 300) C associated with amount weight of black carbon 5wt% added to the diluted rubber. The results of electrical properties measurement of Buna rubber reinforced wit...
To determine how well DNA barcodes from the chloroplast region perform in forest dynamics plots (FDPs) from global CTFS-ForestGEO network, we analyzed DNA barcoding sequences of 1277 plant species from a wide phylogenetic range (3 FDPs in tropics, 5 in subtropics and 5 in temperate zone) and compared the rates of species discrimination (RSD). We quantified RSD by two DNA barcode combinations (r...
Hopea chinensis (synonym: H. hongayensis) (Dipterocarpaceae) is a threatened species found so far in only two locations: Quang Ninh (Vietnam) and Guangxi (China). The species shares many morphological characteristics with H. mollissima and the two species are often confused. To overcome this problem of identification and to investigate the genetic relationships of Hopea species with other Dipte...
MaturaseK gene (MatK) of chloroplast is highly conserved in plant systematics which is involved in Group II intron splicing. The size of the gene is 1500 bp in length, located with in the intron of trnK. In the present study, matK gene from Zingiberaceae was taken for the analysis of variants, parsimony site, patterns, transition/tranversion rates and phylogeny. The family of Zingiberaceae comp...
The plant DNA barcoding is a complex and requires more than one marker(s) as compared to animal barcoding. Mangroves are diverse estuarine ecosystem prevalent in the tropical and subtropical zone, but anthropogenic activity turned them into the vulnerable ecosystem. There is a need to build a molecular reference library of mangrove plant species based on molecular barcode marker along with morp...
ژن کلرپلاستیmatk ، که به عنوان orf509 شناخته شده ، دارای سرعت تکاملی بالا در سطوح نوکلئوتیدی و آمینواسیدی است. این ژن در کپی منفرد بزرگ ژنوم کلروپلاست و بین اگزون های ‘5 و ‘3 trnk (trna-lysine) در درون یک اینترون گروه ii واقع شده است. اثر نور و مرحله نموی بر سطوح rna و پروتئین matk، پیشنهاد کننده نقش کارکردی این ماچوراز مشهور است که به طور غیر مستقیم بر فتوسنتز اثر می گذارد. matk یکی از مناسب ت...
A phylogenetic study of the Opopanax and Crenosciadium was conducted to elucidate their circumscription infrageneric relationships. Sequence data from nrDNA ITS, cpDNA matK trnL-F were used determine relationship. Polymerase Chain Reaction (PCR) amplifications all regions performed using universal primers. Maximum Likelihood (ML) trees constructed PAUP* software, another tree ITS sequences show...
