CYP75B4-Mediated Tricin and Lignin Accumulation Improve Salt Tolerance in Rice.
Article in Rice (New York, N.Y.), 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
Salt stress limits plant growth and agricultural productivity and plants have evolved suitable mechanisms to adapt to salinity environments. It is important to characterize genes involved in plant salt tolerance, which will advance our understanding of mechanisms mediating salt tolerance and help researchers design ways to improve crop performances under high salinity environments. Here, we reported a CYP450 family member, CYP75B4, improves salt tolerance of rice seedlings by inducing flavonoid tricin and cell wall lignin accumulation. The CYP75B4 is highly expressed in tissues rich in cell walls and induced by salt treatment. Subcellular localization analysis revealed that CYP75B4 is localized in the endoplasmic reticulum (ER). The CYP75B4 overexpressing (CYP75B4-OE) lines showed significant enhancement in stem mechanical strength, whereas the cyp75b4 null mutants displayed weaker stems, as compared to the wild-type. Notably, the cyp75b4 and CYP75B4-OE lines showed decreased and improved, respectively, salt tolerance performances in terms of survival rate, ROS accumulation, and Na
