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

Adenine base editors (ABEs) have been exploited to introduce targeted adenine (A) to guanine (G) base conversions in various plant genomes, including rice, wheat and Arabidopsis. However, the ABEs reported thus far are all quite inefficient at many target sites in rice, which hampers their applications in plant genome engineering and crop breeding. Here, we show that unlike in the mammalian system, a simplified base editor ABE-P1S (Adenine Base Editor-Plant version 1 Simplified) containing the ecTadA*7.10-nSpCas9 (D10A) fusion has much higher editing efficiency in rice compared to the widely used ABE-P1 consisting of the ecTadA-ecTadA*7.10-nSpCas9 (D10A) fusion. We found that the protein expression level of ABE-P1S is higher than that of ABE-P1 in rice calli and protoplasts, which may explain the higher editing efficiency of ABE-P1S in different rice varieties. Moreover, we demonstrate that the ecTadA*7.10-nCas9 fusion can be used to improve the editing efficiency of other ABEs containing SaCas9 or the engineered SaKKH-Cas9 variant. These more efficient ABEs will help advance trait improvements in rice and other crops.
