Overexpression of an NF-YB gene family member, EaNF-YB2, enhances drought tolerance in sugarcane (Saccharum Spp. Hybrid).
Article in BMC plant biology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundDrought is one of main critical factors that limits sugarcane productivity and juice quality in tropical regions. The unprecedented changes in climate such as monsoon failure, increase in temperature and other factors warrant the need for development of stress tolerant cultivars to sustain sugar production. Plant Nuclear factor (NF-Y) is one of the major classes of transcription factors that have a major role in plant development and abiotic stress response. In our previous studies, we found that under drought conditions, the nuclear factor NF-YB2 was highly expressed in Erianthus arundinaceus, an abiotic stress tolerant wild genus of Saccharum species. In this study, the coding sequence of NF-YB2 gene was isolated from Erianthus arundinaceus and overexpressed in sugarcane to develop drought tolerant lines.
resultsEaNF-YB2 overexpressing sugarcane (OE) lines had higher relative water content, chlorophyll content and photosynthetic efficiency compared to non-transgenic (NT) control. In addition, overexpressing lines had higher activity of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and glutathione reductase (GR), and higher proline content, lower malondialdehyde (MDA) and peroxide (H
conclusionThis study provides insights into the role of the EaNF-YB2 gene in drought tolerance in sugarcane. Based on the findings of this study, the EaNF-YB2 gene can be potentially exploited to produce drought tolerant sugarcane cultivars to sustain sugarcane production under water deficit conditions.
