Identification of the KNOX Gene Family in Salvia miltiorrhiza Revealing Its Response Characteristics to Salt Stress.

ABSTRACT: Salvia miltiorrhiza is a herbaceous plant that possesses significant medicinal value. Land salinization affects the growth of S. miltiorrhiza, resulting in a decline in its quality and yield. Knotted1-like homeobox (KNOX) genes are transcription factors that play important roles in plant growth and abiotic stress. The characteristics and functions of KNOX genes in S. miltiorrhiza remain unclear. Here, we identified ten KNOX genes in S. miltiorrhiza, all of which possess the characteristic four domains: KNOX1, KNOX2, ELK, and HD. These SmKNOXs were divided into two groups together with homologous genes. Cis-acting element analysis indicated all SmKNOXs contained elements associated with phytohormone, light, and stress response. The SmKNOXs sh
