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

CRISPR/Cas9 systems are nowadays applied extensively to effect genome editing in various organisms including plants. CRISPR from Prevotella and Francisella 1 (Cpf1) is a newly characterized RNA-guided endonuclease that has two distinct features as compared to Cas9. First, Cpf1 utilizes a thymidine-rich protospacer adjacent motif (PAM) while Cas9 prefers a guanidine-rich PAM. Cpf1 could be used as a sequence-specific nuclease to target AT-rich regions of a genome that Cas9 had difficulty accessing. Second, Cpf1 generates DNA ends with a 5' overhang, whereas Cas9 creates blunt DNA ends after cleavage. "Sticky" DNA ends should increase the efficiency of insertion of a desired DNA fragment into the Cpf1-cleaved site using complementary DNA ends. Therefore, Cpf1 could be a potent tool for precise genome engineering. To evaluate whether Cpf1 can be applied to plant genome editing, we selected Cpf1 from Francisella novicida (FnCpf1), which recognizes a shorter PAM (TTN) within known Cpf1 proteins, and applied it to targeted mutagenesis in tobacco and rice. Our results show that targeted mutagenesis had occurred in transgenic plants expressing FnCpf1 with crRNA. Deletions of the targeted region were the most frequently observed mutations. Our results demonstrate that FnCpf1 can be applied successfully to genome engineering in plants.
