Genomic Identification of CCCH-Type Zinc Finger Protein Genes Reveals the Role of in Tolerance of Heat and Salt Stress of Pitaya ().

Pitaya () is cultivated in a broad ecological range, due to its tolerance to drought, heat, and poor soil. The zinc finger proteins regulate gene expression at the transcriptional and post-transcriptional levels, by interacting with DNA, RNA, and proteins, to play roles in plant growth and development, and stress response. Here, a total of 81 CCCH-type zinc finger protein genes were identified from the pitaya genome.
