The TaNHLP1-TaRACK1A module regulates tillering via abscisic acid signaling in wheat.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Wheat tillering is an important agronomic trait influencing grain yield. Here, we identify an NHL repeat-containing protein, TaNHLP1, which positively regulates tiller number in wheat. We discovered that the core components of the abscisic acid (ABA) signaling pathway, type 2C protein phosphatase TaPP2C and SNF1-related protein kinase TaSnRK2, interact with TaNHLP1 to regulate its abundance. Furthermore, TaNHLP1 interacts with the Receptor for Activated C Kinase 1 (TaRACK1A), an ABA pathway negative regulator, and influences its subcellular localization. Importantly, both the TaNHLP1 and TaRACK1A mutations promote ABA accumulation in the shoot bases and tiller buds. Notably, the NHLP1-RACK1 module is conserved across monocots and eudicots, and natural variations in the promoter of TaNHLP1-A enhance its transcriptional activity, leading to increased tiller number and yield. Collectively, these findings elucidate the genetic mechanism of NHLP1-mediated tillering regulation and highlight its potential as a target for improving crop plant architecture.
