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

Unreduced gametes (UGs), also known as 2n gametes, retain the somatic chromosome number and represent a fundamental mechanism for sympatric polyploidization in plants. In common wheat (Triticum aestivum L.) and its triticeae relatives, UGs are not only instrumental in species evolution but may also serve as a powerful tool for modern crop improvement. This review synthesizes progress in understanding the cytological and genetic foundations of UG formation in plants, which primarily arises through meiotic restitution events. The achievements made so far in the exploitation of UGs are detailed, which suggest that appropriate manipulation of UGs has potentials in revolutionizing crop breeding, facilitating de novo synthesis of polyploids, enabling challenging wide hybridizations, and permitting direct introgression of valuable traits from wild relatives into cultivated backgrounds. To fully realize these potentials, there are still many biological and technical hurdles to overcome. We outline the major challenges and propose research directions for further basic and applied studies on UGs, which include elucidating the molecular mechanisms underpinning UG formation, raising the efficiency of UG induction, and integrating UG-based technology with crop genomics and advanced breeding pipelines. Breakthroughs in these areas of research will help to promote a new chapter of crop improvement through enhancing genetic diversities, cultivar innovation, and resilient production of crops in the face of worsening global climate change.
