Genome-Wide Identification of 109 NAC Genes and Dynamic Expression Profiles Under Cold Stress in <i>Madhuca longifolia</i>.

ABSTRACT: Madhuca longifolia (M. longifolia), a tropical tree valued for its medicinal, nutritional, and industrial applications, exhibits severe sensitivity to low-temperature stress in subtropical regions, particularly during seedling establishment. To address this challenge, this study systematically identified 109 NAC genes in M. longifolia and characterized their functional roles in cold adaptation via multi-omics analyses. All NAC proteins were hydrophilic. Key members (e.g., MlNAC026, MlNAC077, MlNAC076) were localized in the nucleus. Phylogenetic analysis grouped them with ANAC072 (RD26), a homolog involved in leaf senescence and ABA-regulated cold stress responses. The NAC family expanded primarily through segmental duplication.
