Differential expression of two O-methyltransferases in lignin biosynthesis in Zinnia elegans.
Caffeic acid 3-O-methyltransferase (CAOMT) and caffeoyl-coenzyme A 3-O-methyltransferase (CCoAOMT) are involved in different methylation pathways in lignin biosynthesis. We previously showed that only the CCoAOMT was markedly induced during lignification in in vitro differentiating tracheary elements (TEs) of Zinnia elegans. To further examine the expression patterns of CAOMT in lignification, ...
متن کاملAn alternative methylation pathway in lignin biosynthesis in Zinnia.
S-Adenosyl-L-methionine:trans-caffeoyl-coenzyme A 3-O-methyltransferase (CCoAOMT) is implicated in disease resistant response, but whether it is involved in lignin biosynthesis is not known. We isolated a cDNA clone for CCoAOMT in differentiating tracheary elements (TEs) induced from Zinnia-isolated mesophyll cells. RNA gel blot analysis showed that the expression of the CCoAOMT gene was marked...
متن کاملCloning and molecular characterization of the basic peroxidase isoenzyme from Zinnia elegans, an enzyme involved in lignin biosynthesis.
The major basic peroxidase from Zinnia elegans (ZePrx) suspension cell cultures was purified and cloned, and its properties and organ expression were characterized. The ZePrx was composed of two isoforms with a M(r) (determined by matrix-assisted laser-desorption ionization time of flight) of 34,700 (ZePrx34.70) and a M(r) of 33,440 (ZePrx33.44). Both isoforms showed absorption maxima at 403 (S...

Saint Joseph Street, Rapid City, SD 57001, USA e-mail: [email protected] Lignin has a significant and largely unrealized potential as a source for the sustainable production of fuels and bulk high-value chemicals. It can replace fossil-based oil as...
