Plastid matK and a fragment of the low-copy nuclear gene PHYC were sequenced for 30 genera of Phyllanthaceae to evaluate tribal and generic delimitation. Resolution and bootstrap percentages obtained with matK are higher than that of PHYC, but both regions show nearly identical phylogenetic patterns. Phylogenetic relationships inferred from the independent and combined data are congruent and di...
DNA barcoding, as a tool for species discrimination, has been efficiently used in animals. However, there are still debates on which DNA region (s) can be adopted as the standard barcode (s) for land plants. In the present study, we evaluated the four proposed barcoding loci (matK, rbcL, trnH-psbA and ITS) on nine species of Nyssaceae. The results showed that ITS was the best performing single ...
Using microarray gene analysis, we found that carboxyl-terminal Src kinase homologous kinase (CHK) regulated the expression of the chemokine receptor, CXCR4. Northern blot and fluorescence-activated cell-sorting analyses showed that CHK down-regulated CXCR4 mRNA and protein levels, respectively. Mutated CHK, which contains a mutation within the ATP binding site of CHK, failed to inhibit CXCR4 e...
I will use David Marker’s book [Mar] as the basic reference for the talks, partly because it’s likely to be the easiest one to find. Other presentations are available: the books by Hodges [Hod], Poizat [PoE] are also excellent (and Poizat in French [PoF] is even better). The classic text on model theory is by Chang and Keisler [ChK]. To go deeper into geometric stability theory you should look ...
Dryobalanops belong to a member of Dipterocarpaceae, which has high economic value. Due illegal harvesting for its wood, the population tends decrease every year, so rapid conservation effort was needed. D. oblongifolia and lanceolata were important members dryobalanops, have listed as endangered (EN), according IUCN. This study aims provide information on DNA isolation amplification process. d...
We present the first national DNA barcode resource that covers the native flowering plants and conifers for the nation of Wales (1143 species). Using the plant DNA barcode markers rbcL and matK, we have assembled 97.7% coverage for rbcL, 90.2% for matK, and a dual-locus barcode for 89.7% of the native Welsh flora. We have sampled multiple individuals for each species, resulting in 3304 rbcL and...

عناب (Zizyphus jujuba Mill.) یکی از گیاهان باغی مهم با گونه‌ها و واریته‌های متنوع در منطقه آسیای مرکزی و غربی است که در بسیاری از مناطق و استان‌های ایران پراکنش طبیعی دارد. این تحقیق با هدف بررسی تنوع ژنتیکی و ژنومی با استفاده از صفات کمی و مارکرهای مولکولی ISSR و RAPD در کلکسیون عناب ایران، شامل نمونه‌های جمع‌آوری شده از هشت استان، در استان خراسان جنوبی انجام شد. تنوع قابل ملاحظه‌ای در میان 29...
