Genome-Wide Identification and Abiotic-Stress-Responsive Expression of CKX Gene Family in Liriodendron chinense.

ABSTRACT: Liriodendron chinense is a tree species of the Magnoliaceae family, an ancient relict plant mainly used for landscaping and timber production due to its excellent material properties and ornamental value. The cytokinin oxidase/dehydrogenase (CKX) enzyme regulates cytokinin levels and plays an important role in plant growth, development, and resistance. However, too-high or too-low temperatures or soil drought can limit the growth of L. chinense, representing a key issue for research. Here, we identified the CKX gene family in the L. chinense genome and examined its transcriptional responses to cold, drought, and heat stresses. A total of five LcCKX genes, distributed on four chromosomes and divided into three phylogenetic groups, were identified ac
