Circadian Clock-Regulated Phosphate Transporter PHT4;1 Plays an Important Role in Arabidopsis Defense

The Arabidopsis accelerated cell death 6-1 （acd6-1） mutant shows constitutive defense, cell death, and ex- treme dwarf phenotypes. In a screen for acd6-1 suppressors, we identified a mutant that was disrupted by a T-DNA in the PHOSPHATE TRANSPORTER 4;1 （PHT4;1） gene. The suppressor mutant pht4;1-1 i...
