Molecular mechanisms of low-temperature sensitivity in tropical/subtropical plants: a case study of <i>Casuarina equisetifolia</i>.

ABSTRACT: Low temperature is a limiting factor affecting plant growth and development. Casuarina equisetifolia, a typical tropical and subtropical tree important for the ecological restoration of coastal beaches, is sensitive to cold stress. By comparing cold tolerance between C. equisetifolia and Arabidopsis, we investigated the molecular basis underlying the cold sensitivity of C. equisetifolia. Transcriptomic analysis showed that the number of cold-induced genes in C. equisetifolia was significantly less than that in Arabidopsis, and notably, the response of cold-induced genes was also delayed in C. equisetifolia. Among the cold-induced genes, C-repeat binding factors (CBFs), the major transcription factors in cold acclimation in A
