Genome-Wide Identification and Expression Analysis of the <i>ClHMGB</i> Gene Family in Watermelon Under Abiotic Stress and <i>Fusarium oxysporum</i> Infection.

ABSTRACT: High-Mobility Group B (HMGB) proteins are conserved non-histone nuclear proteins involved in DNA replication, transcription, recombination, repair; plant growth and development; and stress responses. In this study, we identified nine ClHMGB genes in watermelon using genome-wide search. Phylogenetic and homology analyses classified them into four distinct classes. Synteny analysis revealed that ClHMGB genes share closer evolutionary relationships with dicots than with monocots. Tissue-specific expression profiling showed that eight ClHMGB members exhibit higher transcript levels in female and/or male flowers, suggesting that they play essential roles in floral organ development. Under drought, low-temperature, and salt stresses, ClHMGB members displayed distinct
