TL;DR
This study identifies and characterizes the JRL gene family in tomatoes, revealing their roles in growth, development, and stress response.
Contribution
The first genome-wide analysis of the JRL gene family in tomato, including their structure, evolution, and expression under stress and hormones.
Findings
Eight JRL genes were identified in tomato, unevenly distributed across four chromosomes.
SlJRL genes show tissue-specific expression and respond to various hormones and abiotic stresses.
Phylogenetic analysis grouped tomato JRL genes into seven subgroups with conserved motifs and structures.
Abstract
Jacalin-related lectins (JRLs), a newly discovered subfamily of plant lectins, play an important role in plant growth and development and abiotic stress response. However, in the most important model and economic plant, the tomato, little is known about this gene family. Here, we conducted a genome-wide identification and characterization of the JRL gene family in tomato. A total of eight JRL gene family members (SlJRL1–SlJRL8) were identified based on the tomato genome through bioinformatics analyses, which were unevenly distributed on four chromosomes. Chromosomal localization revealed four pairs of tandemly duplicated genes. Genome collinearity analyses showed that tomato JRL genes were more closely related to Arabidopsis than to rice and maize. Phylogenetic analysis showed that tomato JRL could be divided into seven subgroups, and members within each subgroup shared similar gene…
