Identification, evolutionary diversification, and stress response roles of SmLACSs in Salix matsudana.
Article in BMC genomics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Understanding the mechanisms underlying plant stress tolerance is crucial for improving plant resilience, particularly under challenging environmental conditions. This study investigates the role of long-chain acyl-CoA synthetases in Salix matsudana (SmLACSs), focusing on their evolutionary relationships, functional characterization, and response to environmental stresses. Through a comprehensive analysis, 25 SmLACSs were identified, classified into seven distinct clades, with Clade VII representing a newly discovered subfamily in willow. Evolutionary analysis revealed that segmental duplication and whole-genome duplication were key mechanisms for the expansion of SmLACSs. Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis further indicated that SmLACSs play a role in lipid metabolism, cuticle formation, and stress response pathways. Using RNA-seq and qRT-PCR, differential expression patterns of SmLACSs under salt or submergence stress were observed, highlighting their contribution to stress tolerance, particularly in maintaining cell membrane integrity and lipid homeostasis. These findings provide valuable insights into the roles of SmLACSs in willow’s resilience, and offer potential targets for improving stress tolerance in plants.
