Start codon targeted polymorphism (SCoT) analysis was employed to distinguish 37 whipgrass (Hemarthria compressa L.) clones and assess the genetic diversity and population structure among these genotypes. The informativeness of markers was also estimated using various parameters. Using 25 highly reproducible primer sets, 368 discernible fragments were generated. Of these, 282 (77.21%) were poly...

Genetic diversity and relationships of 54 wild-grown terebinths (Pistacia terebinthus L.) were determined using 40 SSR (simple sequence repeat) markers (38 in silico polymorphic 2 markers). In analysis, 430 alleles identified. The number per locus ranged from 3 to 25 with a mean value 11 locus. values polymorphism information content (PIC) 0.34 (CUPOhBa4344) 0.91 (CUPSiBa4072) PIC 0.68. distanc...

The classification of bamboos based on floral morphology and reproductive characters is very hard due to erratic flowering behavior and unusually long reproductive cycle. The application of reliable and effective DNA molecular markers is highly essential to address this problem. In the present investigation, inter-simple sequence repeats (ISSR) markers were employed to study phylogenetic relati...

The present experiment was conducted during 2016-18 at Division of Fruits and Horticultural Technology, ICARIARI, New Delhi. A total 40 Kinnow mutants 1 wild type were selected for molecular characterization diversity analyses. Thirty-four SSR markers screened polymorphism, which only 2 found informative. Twelve alleles detected among SSRs with an average 6 per locus the highest number (7) reco...

The cerebral blood flow is divided into an anterior circulation and a posterior circulation connected to each other in the form of a circle called Circle of Willis (CW). It is formed by the unification of the internal carotid (ICA) and vertebrobasilar systems Posteriorly, the basilar artery, formed by the left and right vertebral arteries, branches into a left and right posterior cerebral arter...

UNLABELLED For characterization of genetic diversity in genotypes several molecular techniques, usually resulting in a binary data matrix, have been used. Despite the fact that in Cluster Analysis (CA) and Principal Coordinates Analysis (PCoA) the interpretation of the variables responsible for grouping is not straightforward, these methods are commonly used to classify genotypes using DNA mole...

The premammillary artery (PMA) is a branch of the posterior communicating artery (PCoA). While the PMA is known to originate from the PCoA as demonstrated by most anatomical studies, it originates directly from the internal carotid artery in approximately 1% of patients. Cerebral aneurysms associated with the PMA have rarely been reported. We report an extremely rare case of a ruptured PMA aneu...

BACKGROUND AND PURPOSE Transcranial Doppler (TCD) can localize arterial occlusion in stroke patients. Our aim was to evaluate the frequency of specific TCD flow findings with different sites of arterial occlusion. METHODS Using a standard insonation protocol, we prospectively evaluated the frequency of specific TCD findings in patients with or without proximal extracranial or intracranial occ...

Precipitation is considered a key factor influencing the fluorescent dissolved organic matter (FDOM) of urban rivers. However, multiple effects precipitation on FDOM in rivers and long-term impacts spatial patterns are seldom known. Spatiotemporal variations at 36 sites from Jinan City during dry wet seasons were investigated this study. Four components identified using an excitation–emission m...
