Pathogen-induced condensation of the guard cell RNA-binding protein SAIR1 fine-tunes translation for immunity.

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
Plant guard cells perceive pathogens and close stomata to prevent their invasion. Biomolecular condensates are membraneless organelles essential for life processes. However, guard cell biomolecular condensates mediating stomatal immunity remain unknown. Here we identify a guard-cell-preferential RNA-recognition-motif-type RNA-BINDING PROTEIN, STOMATAL IMMUNE RNA-BINDING PROTEIN 1 (SAIR1), that forms pathogen-responsive guard cell condensates via phase separation. Upon perception of the pathogen molecular pattern flg22, the activated kinases MPK3 and MPK6 phosphorylate SAIR1 and trigger its condensation in guard cells for stomatal immunity. SAIR1 condensates recruit translational regulators such as POLYADENYLATE-BINDING PROTEINs and eIFiso4G, and sequester defence-related mRNAs, including key components of the salicylic acid pathway. Through these interactions, SAIR1 condensates enhance the translation of defence mRNAs, ultimately promoting stomatal closure. Our findings reveal phosphorylation-regulated SAIR1 condensates as a critical hub that links flg22-MPK3/6 signalling to stomatal immunity.
