Integrative transcriptomic and metabolomic analysis elucidates the vital pathways underlying the differences in salt stress responses between two chickpea (Cicer arietinum L.) varieties.

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
backgroundSalinity, a major abiotic stress, significantly impairs crop productivity by inducing osmotic, ionic, and secondary stresses that disrupt metabolic processes. Chickpea (Cicer arietinum L.), a diploid annual legume of the Fabaceae family, is one of the major pulse crops cultivated by farmers with limited resources. While previous studies have explored salt tolerance in chickpeas, this study provides a comprehensive multi-omics perspective. Exploring the mechanism of chickpea adaptation to the saline environment can effectively supplement the problem of single source of plant protein.
resultsThe present study analyzed the transcriptomic and metabolomic profiles of two distinct chickpea varieties, DY3 and DY1, with contrasting salinity tolerance capacities. The salinity tolerance of DY3 was associated with greater biomass, higher antioxidant enzyme activity, and higher photosynthetic efficiency. Transcriptomic analysis revealed that the genes induced in DY3 under salinity stress were associated with ion homeostasis, antioxidant defense system, and plant hormone signaling. Metabolomics analysis revealed significant enrichment of components of diverse secondary metabolites pathways, as well as carbohydrate metabolism. Integrated multi-omics analysis highlighted the anthocyanin biosynthesis pathway, functioning within the broader flavonoid metabolic network, as a key regulator of salt tolerance in the chickpea. Subsequent, RT-qPCR confirmed the upregulation of key genes associated with anthocyanin metabolism.
conclusionsThese findings reveal the key regulatory role of the flavonoid pathway in salt tolerance of chickpeas, offering insights for breeding improved varieties.
