Title
NUT1-Exo70A1 Regulates Xylem Vessel Development and Influences Water Use Efficiency in Maize

Other claims from this paper (7)
- Observation A recessive maize mutant ds1, highly susceptible to water deficit, was identified.
- Observation The ds1 mutant is defective in secondary cell wall patterning and xylem vessel differentiation.
- Observation The ds1 mutant shows significantly reduced hydraulic conductivity.
- Observation DS1 is the maize ortholog of Arabidopsis Exo70A1.
- Observation DS1 is regulated by the NAC transcription factor NUT1 in vascular tissues.
- Intervention effect Overexpressing Exo70A1 boosted biomass and grain yield under both well-watered and drought conditions.
- Recommendation The authors propose the NUT1-Exo70A1 module as a promising genetic target for improving water use efficiency in crops.
