Overexpression of the Medicago falcata NAC transcription factor MfNAC3 enhances cold tolerance in Medicago truncatula

•We cloned and identified a gene, MfNAC3, which encodes a NAC-type transcriptional factor from M. falcate.•MfNAC3 was induced under salt, drought and cold stress.•Overexpression of MfNAC3 was shown to enhance cold tolerance in M. truncatula.•We provided evidence that MfNAC3 is a positive regulator o...
