Genome-wide identification and expression profiles of NAC transcription factors in Poncirus trifoliata reveal their potential roles in cold tolerance.

ABSTRACT:

Background

Citrus, a globally vital economic crop, faces severe challenges due to extreme climatic conditions and diseases/pests attack. Poncirus trifoliata is closely related to citrus and shows unique cold tolerance, making it a crucial material for unraveling genes involved in cold tolerance. NAC (NAM, ATAF1/2, CUC2) transcription factors play important roles in plant growth, development, and stress responses. However, their evolution patterns and gene functions in citrus remain poorly studied. This study aims to elucidate the genomic characteristics and evolution of the NAC genes in P. trifoliata, and to analyze their expression patterns and conduct functional validation under cold stress.

Results

Genome-wide analysis identified 135 PtrNAC genes in P. trifoliata with non
