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

backgroundThe high-frequency induction rate of haploid is crucial for double haploid (DH) breeding. The combination of multiple haploid-induced genes, such as ZmPLA1/MATL/NLD and ZmDMP, can synergistically enhance the haploid induction rate (HIR) in maize. However, the potential synergistic effects between OsMATL and OsDMP genes in rice remain unclear.

resultsKnocking out OsMATL in both HuaHang No.48 (HH48) and Nipponbare (NIP) cultivars resulted in reduced seed setting rate (SSR) and haploid induction (HI). Notably, in this study, the HI capacity of OsMATL knockout mutants in indica rice surpassed that of japonica rice knockout mutants, with the proton active site in the third exon exhibiting a higher HIR compared to the first and fourth exons. Furthermore, when OsDMP1 or OsDMP3 was combined with OsMATL, they increased HIR, and an antagonistic relationship was observed between HIR and SSR in HH48

conclusionsIn rice, the proton active site in the third exon of OsMATL exhibited higher induction efficiency, and OsDMP1 or OsDMP3 exerted a synergistic effect with OsMATL. These findings provide a foundation for further research on DH breeding in rice.
