In silico analysis of L- and G-type lectin receptor kinases in tomato: evolution, diversity, and abiotic responses.

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
Solanum lycopersicum (family: Solanaceae) is a crucial crop and model organism for many phenotypic traits, and its sequenced genome provides valuable insights into plant biology and crop improvement. This study investigated lectin receptor-like kinases (LecRLKs) in tomato, focusing on L-type and G-type families. Mining the tomato genome (ITAG2.4) revealed 161 putative lectin genes across seven families, with GNA-related genes being the most abundant. Gene duplication analysis indicated that tandem and segmental duplications were the primary mechanisms driving LecRLK gene family expansion, particularly for G-type LecRLKs. These duplicated genes showed evidence of both purifying and negative selection, suggesting functional conservation and sub-functionalization. L-type and G-type LecRLKs exhibited diverse domain rearrangement architectures and subcellular localizations, with G-type LecRLKs showing greater expansion and architectural diversity. Differential expression analysis during abiotic stress (drought, heat, and cold stress) revealed key responsive genes. During drought stress, 63.2% of L-type and 18.5% of G-type LecRLK genes were expressed, with L-type Solyc09g005000.1 and G-type Solyc03g078360.1 genes showing significant 2-fold upregulation. Heat stress (42 °C) induced the upregulation of L-type Solyc04g071000.1 and G-type Solyc03g078360.1 and Solyc04g008400.1, particularly after 12-24 h of exposure. Promoter analysis revealed numerous stress-related cis-elements. Transcription factor predictions and miRNA targeting sites suggest complex regulatory mechanisms. This comprehensive in silico characterization of tomato LecRLKs, including their expansion patterns and evolutionary pressures, provides insights into their potential roles in abiotic stress responses and lays the groundwork for enhancing crop resilience through targeted breeding or genetic engineering approaches.
