The use of molecular marker in the dairy sector is gaining large acceptance as a reliable diagnostic approach for food authenticity and traceability. Using a PCR approach, the rbcL marker, a chloroplast-based gene, was selected to amplify plant DNA fragments in raw cow milk samples collected from stock farms or bought on the Italian market. rbcL-specific DNA fragments could be found in total mi...

background:confirmation of olive oil authenticity and particularly virgin olive oil has a great importance. several advanced chemical and genetic analyses have been used to monitor especial components; however each has its limitations especially when detecting hazelnut-adulterated olive oil. objectives:the objective of this research is to assess the presence of trace amount of hazelnut oil in o...

A new species of mesophotic marine red algae, Ethelia hawaiiensis sp. nov., is illustrated and described. distinguished from other members the genus by its large diameter assurgent filament cells, in having thallus cavities that are frequently inhabited microalgae, as well DNA sequence. Analyses mitochondrial COI, plastid rbcL, nuclear SSU sequences demonstrated E. was distinct it not phylogene...

Photosensory phytochromes perceive mainly red and far-red light and utilize a linear tetrapyrrole chromophore, phytochromobilin, for their photoactivity in plants. Although phytochromes have been extensively studied for light-dependent regulation of numerous developmental processes, our understanding of the molecular mechanisms responsible for distinct organand tissue-specific phytochrome respo...

DNA barcoding relies on the use of a standardized DNA region as a tag for simple, rapid and affordable species identification. To get hands-on experience on species identification using molecular tools and to explore the genetic biodiversity of New York City, we participated in the Urban Barcoding Project conducted by the DNA Learning Center of Cold Spring Harbor Lab (CSHL). The gene region tha...

A unicellular red microalga was isolated from environmental freshwater in Korea, and its morphological, molecular, and biochemical properties were characterized. Morphological analysis revealed that the isolate was a unicellular biflagellated green microalga that formed a non-motile, thick-walled palmelloid or red aplanospore. To determine the taxonomical position of the isolate, its 18S rRNA a...

In order to understand how Synechococcus in the estuarine environment (Chesapeake Bay) are phylogenetically related to other known marine Synechococcus, partial rbcL gene sequences from 25 strains of Synechococcus spp. isolated from estuarine, coastal and oceanic waters were sequenced. The rbcL gene phylogeny showed that Chesapeake Bay Synechococcus isolates together with other marine Synechoco...
