An Engineered Abscisic Acid Receptor Enhances ABA Signaling and Improves Abiotic Stress Tolerance in Rice.

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
Abscisic acid (ABA) is a key phytohormone that orchestrates adaptive responses in plants exposed to abiotic stress. The ABA signaling cascade is triggered by ABA-mediated binding of PYRABACTIN RESISTANCE1-LIKE (PYL) receptors to clade A Type 2 C protein phosphatases (PP2CAs). In Arabidopsis thaliana, several constitutively active variants of ABA receptors have been described, offering valuable tools for improving plant tolerance to environmental stresses. To identify amino acid residues in the rice ABA receptor OsPYL5 that are involved in ABA-independent interactions, we implemented a random mutagenesis strategy followed by yeast two-hybrid (Y2H) screening. We identified residues L-93 and N-102 as key residues that influence the ABA independent interaction of OsPYL5 with OsPP2CA51. Substituting these residues with T or Y significantly enhanced the activity of an ABA-responsive reporter in rice protoplasts, even in the absence of ABA treatment. We therefore engineered a double-point mutant, OsPYL5
