DNA barcoding and phytochemical profiling of wild plant "Lal lat tan" from Imugan, Sta Fe, Nueva Vizcaya, Philippines

open access: yesInternational Journal of Secondary Metabolite, 2018
The Philippines hosts a wide-ranging diversity of plant species with pharmacological potential. Species identification on the basis of DNA sequences has been done for some time in plants and used to detect variations among the sequences specifying ...

Large scale genomic analysis of 3067 SARS-CoV-2 genomes reveals a clonal geo-distribution and a rich genetic variations of hotspots mutations.

open access: yesPLoS ONE, 2020
In late December 2019, an emerging viral infection COVID-19 was identified in Wuhan, China, and became a global pandemic. Characterization of the genetic variants of SARS-CoV-2 is crucial in following and evaluating it spread across countries.

Piecing the barcoding puzzle of Palearctic water frogs (Pelophylax) sheds light on amphibian biogeography and global invasions

open access: yesGlobal Change Biology, Volume 30, Issue 3, March 2024.
By revisiting three decades of molecular data, we retraced the evolution and mapped the diversity of Pelophylax water frogs, a famous group of Eurasian amphibians. The results highlight the Paratethys Paleo‐sea as a major driver of diversification, implement a new timetree validation approach, emphasize the rare ability of lineages to hybridize despite

Phylogenetic analysis of Escherichia coli isolates from healthy and diarrhoeic calves in Mashhad, Iran [PDF]

open access: yesBulgarian Journal of Veterinary Medicine, 2017
Escherichia coli is a normal inhabitant of the gastrointestinal tract of vertebrates. Certain Escherichia coli strains have been associated with neonatal diarrhoea in ruminants. These strains can be assigned to one of the four main phylogenetic groups, A,
