Fine mapping and candidate gene analysis of qRN5a, a novel QTL promoting root number in rice under low potassium.

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
key messageqRN5a, a novel QTL for increasing root number under low K in rice, was fine mapped to a 48.8-kb region on chromosome 5, and LOC_Os05g27980 is the most likely candidate gene. Potassium (K) is a mineral nutrient essential for plant growth and development, but the molecular mechanism for low-K (LK) tolerance in rice remains poorly understood. In our previous study, the quantitative trait locus (QTL) qRN5a for root number (RN) under LK was identified in the chromosome segment substitution line CSSL35 carrying segments from XieqingzaoB in the genetic background of Zhonghui9308 (ZH9308). CSSL35 developed more roots than ZH9308 under LK at the seedling stage, and qRN5a was initially located within a 1,023-kb genomic region. In this study, to understand the molecular basis of qRN5a, a large F
