Genome-Wide Identification of LATERAL ORGAN BOUNDARIES DOMAIN (LBD) Transcription Factors and Screening of Salt Stress Candidates of Rosa rugosa Thunb.

ABSTRACT: LATERAL ORGAN BOUNDARIES DOMAIN (LBD) transcription factors are regulators of lateral organ morphogenesis, boundary establishment, and secondary metabolism in plants. The responsive role of LBD gene family in plant abiotic stress is emerging, whereas its salt stress responsive mechanism in Rosa spp. is still unclear. The wild plant of Rosa rugosa Thunb., which exhibits strong salt tolerance to stress, is an ideal material to explore the salt-responsive LBD genes. In our study, we identified 41 RrLBD genes based on the R. rugosa genome. According to phylogenetic analysis, all RrLBD genes were categorized into Classes I and II with conserved domains and motifs. The cis-acting element prediction revealed that the promoter regions of most RrL
