Gene Details:
- Gene ID: Ma06_g28730
- Gene Symbol: MaNAC1
- Gene Name: NAC transcription factor1
- Genome: banana A genome
- Species: Musa acuminata
Functional Descriptions:
- Our findings revealed that MaNAC1 performs a vital role as a positive modulator in modulating cell wall cellulose metabolism within banana fruit under chilling stress.
- Banana MaNAC1 activates secondary cell wall cellulose biosynthesis to enhance chilling resistance in fruit.
- An increase in cell wall thickness and cellulosic glucan content was observed in MaNAC1-overexpressing Arabidopsis lines, indicating that MaNAC1 participates in cellulose biosynthesis.
- The activation of MaCESA7 and MaCESA6B cellulose biosynthesis genes can be directly induced by MaNAC1 through binding to SNBE motifs within their promoters, leading to enhanced cellulose content during low-temperature stress.
- Banana fruit NAC transcription factor MaNAC1 is a direct target of MaICE1 and involved in cold stress through interacting with MaCBF1.
- Taken together, these results suggest that the cold-responsive MaNAC1 may be involved in cold tolerance of banana fruits through its interaction with ICE1–CBF cold signalling pathway, providing new insights into the regulatory activity of NAC TF.
