Improving grain yield and salt tolerance by optimizing plant height with beneficial haplotypes in rice (Oryza sativa).
Article in Journal of advanced research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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
introductionRice (Oryza sativa L.), a staple food for billions worldwide, is challenged by salt stress. Owing to the limited understanding of the physiological and genetic basis of rice salt tolerance, few genes have been identified as valuable in rice breeding, causing a major bottleneck in the development of high-yield, salt-tolerant rice varieties.
objectiveThis study aims to identify salt tolerance genes/quantitative trait loci (QTLs) with breeding potential in rice.
methodsField trials were conducted with 166 Chinese rice cultivars from saline-affected regions and 412 global rice accessions to assess salt tolerance. Genome-wide association study (GWAS) was performed to identify key loci related to high yield and salt tolerance. Additionally, the impact of introducing beneficial haplotypes on grain yield and salt tolerance was assessed.
resultsThe optimal rice plant height of 100-120 cm was crucial for sustaining high yield under both normal and salt stress conditions. GWAS revealed 6 novel QTLs/genes associated with rice plant growth and grain yield across various environments, distinct from previously recognized salt stress-related genes. Notably, the gene PHS10.1, encoding a serine/threonine protein kinase, may regulate carbon metabolism, starch and sucrose metabolism, influencing plant growth and grain yield. Certain haplotypes of the genes regulating plant height and grain yield, including SD1, Ghd7.1, GH3.5, and PHS10.1, were selected in traditional breeding. Moreover, optimizing plant height through the introgression of beneficial alleles of these genes increased grain yield in recipient lines under both normal and saline conditions.
conclusionWe propose that utilizing beneficial haplotypes to optimize plant height can effectively balance the growth-stress trade-offs in rice plants. This represents a promising breeding strategy for the development of crop varieties that are both high-yielding and salt-tolerant.
