zinnia peruviana/papillon-lefevre disease

During differentiation of isolated Zinnia mesophyll cells into tracheary elements (TEs), lignification on TEs progresses by supply of monolignols not only from TEs themselves but also from surrounding xylem parenchyma-like cells through the culture medium. However, how lignin polymerizes from the

To determine the regulatory mechanism of gene expression in the early stages of tracheary element (TE) differentiation, we isolated and characterized a genomic fragment of TED3 whose mRNA is expressed preferentially in differentiating TEs 12-24 h before morphological changes in the in vitro Zinnia
