N. Koizumi et al., CATIONIC PEROXIDASES SECRETED FROM CULTURED-CELLS MAY LOCALIZE TO APOPLASTS IN TOBACCO PLANT-ROOTS, Bioscience, biotechnology, and biochemistry, 62(8), 1998, pp. 1609-1611
The transcripts for 38-kDa and 40-kDa cationic peroxidases of tobacco
plants are accumulated in cultured cells, cultured roots, and roots of
intact plants. In roots, 38-kDa and 40-kDa peroxidases appear to be l
ocalized to apoplasts, where peroxidase proteins may possibly be bound
to the cell wall.
