Towards Identifying Cis and Trans Regulators of Expression of Xylem Cysteine Protease 1 (XCP1) in Arabidopsis
… thick-walled water-conducting cells known as tracheary elements. Understanding tracheary element differentiation and maturation is of scientific and commercial importance as it may lead to broad understanding of cellular differentiation processes as well as ways to increase both the quality …

Promoter Deletion Analysis of Xylem Cysteine Protease 2 (XCP2) in Arabidopsis thaliana
The process of xylem tracheary element differentiation involves the coordination of vascular cambium activity, cell fate determination, cell expansion/elongation, secondary wall synthesis, programmed cell death, and cellular autolysis. The end result of tracheary element differentiation is a …

Function and Regulation of Xylem Cysteine Protease 1 and Xylem Cysteine Protease 2 in Arabidopsis
A functional water-conducting system, the tracheary elements of the xylem, is required to sustain plant growth and development. Tracheary element formation is dependent on many biological processes terminated by programmed cell death and cellular autolysis. The final two processes are probably …

Tissue and Cell-Type Localization and Partial Characterization of a Xylem Papain-Type Cysteine Protease From Arabidopsis
Cysteine proteases are associated with xylem tracheary element differentiation. XCP1 was recently identified as a xylem-specific cysteine protease in Arabidopsis (Zhao, et al., 2000). For this study a recombinant polyhistidine-tagged XCP1 (XCP1H6) was expressed and purified from an E. coli …

The Role of the Ubiquitin-Proteasome Pathway During Xylem Differentiation in <I>Zinnia elegans</I> Mesophyll Cells and <I>Arabidopsis thaliana</I>
… differences between differentiating cells of tracheary element (TE) cultures and non-differentiating cells of control cultures. The pathway is highly active throughout development of differentiating TEs, a programmed cell death (PCD) process during which the majority of cellular proteins and …
