Detection and characterization of a putative emaravirus infecting Clematis brevicaudata DC. in China.

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
A novel emaravirus, tentatively named "clematis yellow mottle associated virus" (CYMaV), was identified through transcriptome sequencing and RT-PCR analysis of yellow-mottled leaf samples from Clematis brevicaudata DC. The genome of CYMaV consists of five viral RNAs: RNA1 (6591 nucleotides, nt), RNA2 (1982 nt), RNA3a (1301 nt), RNA3b (1397 nt), and RNA4 (1192 nt). The 13-nt sequences at the 5'- and 3'-termini of the CYMaV RNAs are conserved and have reverse complementary, as typically seen in emaraviruses. The proteins encoded by CYMaV shared the highest amino acid sequence similarity with those of the unclassified Karaka Okahu purepure emaravirus (KOPV), with 60.2% identity in the RNA-dependent RNA polymerase (RdRp), 44.4% in the glycoprotein precursor, and 46.9% in the nucleocapsid protein. A phylogenetic tree based on amino acid sequences of the RdRp revealed that CYMaV is most closely related to KOPV and clusters with ChMaV (chrysanthemum mosaic-associated virus, LC576445) and PCLSaV (pear chlorotic leaf spot-associated virus, MK602177) in one distinct clade. Transmission electron microscopy observation of negatively stained samples from C. brevicaudata revealed spherical virus-like particles (VLPs) approximately 100 nm in diameter. Five primers, specific for each viral RNA, were used to detect CYMaV in 11 symptomatic and two asymptomatic C. brevicaudata samples, but the results failed to show a consistent association of viral infection with symptoms. CYMaV can be considered a putative new member in the genus Emaravirus, and this marks the first report of an emaravirus found infecting C. brevicaudata plants.
