ZmDRZ1 negatively regulates drought tolerance via modulating ABA signaling pathway in maize.

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 messageZmDRZ1 serves as a negative regulator of drought tolerance in maize seedlings by modulating stomatal closure through an ABA-dependent signaling pathway. Drought is one of the major risk factors for maize (Zea mays L.) yield. Some genes controling drought resistance have been cloned, but the role of drought resistance is still not clear in maize. The RING (Really Interesting New Gene) domain-containing protein family plays critical role in abscisic acid (ABA) signaling pathways that orchestrate plant responses to abiotic stress. Here, we characterized the RING protein family of maize and identified a novel RING-v gene, designated drought-related RING Zinc finger 1 (ZmDRZ1). Tissue-specific expression analysis indicated that ZmDRZ1 expression was significantly down-regulated in maize seedlings under drought conditions. CRISPR/Cas9-mediated knockout of ZmDRZ1 enhanced drought resistance by increasing ABA content, promoting stomatal closure, and improving photosynthetic performance. Conversely, ZmDRZ1- overexpression (OE) lines exhibited reduced relative water content, elevated levels of malondialdehyde (MDA) and hydrogen peroxide (H
