Genome-Wide Identification and Characterization of the NAC Gene Family and Its Involvement in Cold Response in .

The NAC (NAM, ATAF1/2 and CUC2) gene family is one of the largest plant-specific transcription factor families, functioning as crucial regulators in diverse biological processes such as plant growth and development as well as biotic and abiotic stress responses. Although it has been widely characterized in many plants, the significance of the NAC family in remained elusive up to now. In this study, a genome-wide search method was conducted to identify NAC genes in (DoNACs) and a total of 110 putative DoNACs were obtained.

Genome-Wide Characterization and Expression Analysis of HD-ZIP Gene Family in .

The homeodomain-leucine zipper (HD-ZIP) gene family, as one of the plant-specific transcription factor families, plays an important role in regulating plant growth and development as well as in response to diverse stresses. Although it has been extensively characterized in many plants, the HD-ZIP family is not well-studied in , a valuable ornamental and traditional Chinese medicinal herb. In this study, 37 HD-ZIP genes were identified in () through the genome search method, and they were classified into four subfamilies based on phylogenetic analysis.
