Xylem parenchyma cells deliver the H2O2 necessary for lignification in differentiating xylem vessels (2005, methodology): “H2O2 production by xylem elements may also be monitored by confocal scanning laser microscopy using fluorescent indicators, such as 2,7-dichlorofluorescein diacetate (DCFH-DA; Groover et al. 1997).”
Hypersensitive response-related death (2000, background): “Interestingly, the rapidity of cell disruption in the P. infestans-induced HR also has some resemblance to that seen during the PCD in differentiating tracheary elements in which the cell dies through a rapid disruption of the plant vacuole ( Groover et al., 1997; Groover and Jones, 1999).”
Comprehending crystalline β-carotene accumulation by comparing engineered cell models and the natural carotenoid-rich system of citrus (2011, unknown): “These data, together with several whole plant studies, suggest that PCD during tracheary element differentiation is an orderly and actively regulated cell-autonomous process (Fukuda and Komamine, 1980; Groover et al., 1997).”
