Establishment of an efficient and PAM-relaxed LbCas12a genome editing tool in plants.

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
Cas12a is widely used in plant genome editing, but its targeting scope is constrained by stringent protospacer adjacent motif (PAM) requirements and variable activity across species, limiting its application at diverse genomic loci. LbCas12a-RRV-based editing system was established in nonheading Chinese cabbage, and T5exo-PF-LbCas12a was generated by introducing a triple mutation (D535G/S551F/D665N) and fusing with T5 exonuclease. This engineered system recognizes an expanded PAM sequence from 5'-VTTV-3' to 5'-NYHV-3'. The system exhibited efficient editing at noncanonical PAM sites in cabbage, tomato, and rice. Additionally, it successfully mediated large-fragment deletions via microhomology-mediated end joining (MMEJ) in plants. This study expands Cas12a targeting scope in plants and provides the first evidence for Cas12-mediated MMEJ-based large-fragment deletion. The toolkit facilitates functional genomics and crop improvement, and the methodology is readily adaptable to other plant species.
