OsVDE, a xanthophyll cycle key enzyme, mediates abscisic acid biosynthesis and negatively regulates salinity tolerance in rice.
Article in Planta, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 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
MAIN
conclusionOsVDE, a lipocalin-like protein in chloroplasts, negatively regulated the ABA biosynthesis and stomatal closure under salt stress in rice seedlings. Violaxanthin de-epoxidase (VDE) is a key enzyme of xanthophyll cycle. It plays a critical role in abscisic acid (ABA) biosynthesis, growth and stress responses in plants. Although functions of several VDE genes have been characterized, it is largely unknown whether OsVDE regulates the ABA biosynthesis and salt stress tolerance in rice. In this study, we generated the OsVDE overexpressing and CRISPR-Cas9-mediated gene-editing transgenic lines, and identified that the gene-editing mutant lines showed the dwarfism, shorter panicle and lower seed-setting rate than the wild type whereas the overexpression lines did not exhibit the difference from the wild type. In addition, the gene-editing transgenic lines were hypersensitive to exogenous ABA during germination. Under salt stress, the gene-editing transgenic seedlings had a higher ABA level, higher stomatal closure percentage and higher survival rate than the wild type. The qRT-PCR analysis confirmed that OsVDE negatively regulated the OsNECD2/4/5 expressions, ABA biosynthesis and salt stress tolerance in rice seedlings. These results provide new evidence that VDE plays an essential role in ABA biosynthesis and salt stress tolerance in plants.
