Complete genome characterization and population dynamics of potato virus Y-NTN strain from India.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Potato virus Y (PVY) is a major threat to potato cultivation worldwide. PVY exists as biologically and genetically distinct strains and causes varying degrees of pathogenicity and a wide range of symptoms in potato. Knowledge of the nature of PVY strains is essential for breeding PVY resistant cultivars that are durable against a wide range of strains. We report the complete genome of a PVY potato isolate (JK12) characterised from the potato production areas of Jammu and Kashmir, India. Nucleotide sequence comparisons and phylogenetic analysis with known PVY strains revealed that the isolate belongs to the NTN strain of PVY. At the whole genome sequence level, the JK12 isolate shared the highest identity (99.42%) with PVY-NTN strains reported from Germany, followed by those from United Kingdom (99.34%) and Japan (99.33%). Recombination detection analysis identified two recombination break points and JK12 appeared to have originated from a recombination event between a PVY-N strain from Belgium as a major parent and a PVY-O strain from China as the minor parent. Our results suggest possible mutation and recombination could be the basis for the evolution and the subsequent establishment of NTN in this region. Furthermore, a global evolutionary lineage analysis of all the known PVY strains showed relatively low nucleotide diversity among the PVY-NTN strains. Neutrality tests showed that all the genotypes of PVY are undergoing purifying selection suggesting population expansion of PVY. This is the first report of complete genomic characterization of an NTN strain of PVY isolated from commercial potato fields in India. The implications of the emergence of this strain in the Indian context are discussed.
