HCHO-uptake kinetics by DAS/DAK leaves from a HCHO solution was investigated.
HCHO can be assimilated via the DAS/DAK pathway under a short stress of liquid HCHO.
Original HCHO metabolic pathways did not function in liquid HCHO-treated transgenic leaves.
Function of the DAS/DAK pathway enhanced HCHO uptake by transgenic leaves.
Contribution of the DAS/DAK pathway to HCHO uptake by DAS/DAK leaves was evaluated.
