1 · What the graph read from it

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.

2 · The registry

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

We present the first chromosome-level genome assembly and annotation for the genus Cuscuta, a twining and leafless parasitic plant of the morning glory family (Convolvulaceae). C. campestris, the study species, is a widely studied model parasite, due in part to its worldwide occurrence as a weed of agricultural and natural plant communities. The species has served as a model parasite for studies of parasite biology, haustorium development, growth responses to chemical and light stimuli, gene content and expression, horizontal gene transfer, and interspecies RNA movement and has a recently developed transformation system. The 505 Mb (1C) genome is assembled into 31 chromosomes and supports annotation of 47,199 protein-coding genes, 214 small RNA loci (including 146 haustoria-specific miRNAs), and 3,238 interspecies mobile mRNA loci. C. campestris is a recent tetraploid with a high retention of duplicated genes and chromosomes, with less than 8% nucleotide divergence between homoeologous chromosomes. We also show that transformation of C. campestris with the RUBY marker system allows visualization of transformed Cuscuta-derived fluorescent mobile molecules that have entered the host stem. This genome, with an associated genome browser and BLAST server, will be of value for scientists performing fundamental research in a wide range of molecular, developmental, population, and evolutionary biology, as well as serve as a research tool for studying interspecies mobile molecules, generating genetic markers for species and genotype identification, and developing highly specific herbicides.
