The syringaldazine-oxidizing peroxidase PXP 3-4 from poplar xylem: cDNA isolation, characterization and expression

In many plants species, including poplar, the peroxidase-directed oxidation of the lignin analogue syringaldazine (SYR) has been localized to cells that undergo secondary wall formation, a process that includes lignification. As a first step to analyse the corresponding peroxidases. we have isolated previously two anionic isoenzymes (PXP 3-4 and PXP 5) from poplar xylem (Populus trichocarpa), which use SYR as a substrate. Here, we demonstrate that these enzymes are responsible for the visualized SYR oxidation in the developing xylem. The cDNA that corresponds to PXP 3-4 was isolated and the deduced protein was found closely related to the other SYR-oxidizing peroxidase PXP 5 (ca. 98% of identity). PXP 3-4 was expressed in a baculovirus expression system yielding high levels of active peroxidase (3 mg/l medium). The heterologously produced protein showed characteristics similar t...

Activity of glyceraldehyde-3-phosphate dehydrogenase isozymes during photoperiodic floral induction in spinach leaves

by Hubert Greppin and Patrice Simon

ABSTRACT The activity of NAD+ and NADP+-dependent glyceraldehyde-3-phosphate dehydrogenase isozym... more ABSTRACT The activity of NAD+ and NADP+-dependent glyceraldehyde-3-phosphate dehydrogenase isozymes (EC 1.2.1.12 and EC 1.2.1.13, respectively) were measured in spinach (Spinacia oleracea L. cv. Nobel) leaves grown under different photoperiodic treatments in order to discriminate between the early events of floral induction and processes related to acclimation. Glycolysis-linked isozyme activities were increased not only during floral induction and acclimation, but also during acclimation alone, suggesting that the changes in cytosolic activities were most probably associated with acclimation. In contrast, the chloroplast-linked isozyme activities only increased during flower induction and appeared to be specifically associated with the initiation of the flowering process. The relative activity changes in the chloroplast and cytosol compartments may thus be supposed to be among the first signs of translation of the photoperiodic signal into cytosolic and cellular metabolic adaptation, whereby the leaf moves rapidly into a new metabolic state.
