Plant Respiration under the Influence of Heavy Metals

  • R. Lösch
  • K. I. Köhl


The effect of transition metals and Al on plant catabolism has received less attention than their effect on other metabolic traits. Applied and ecological studies concentrate on the role of metal exclusion from the symplast or metal sequestration in the vacuole for plant survival on substrates with toxic metal concentrations (Ernst 1969, 1976; Denny and Wilkins 1987). Physiological studies about metabolic effects of excess levels of heavy metals focus on effects on photosynthesis (Vallee and Ulmer 1972; Clijsters and Van Assche 1985) and, more recently, on specific gene expression (Tomsett and Thurman 1988). The lack of detailed insight into heavy metal interactions with metabolic processes and with other ions hinders causal understanding of toxicity and tolerance mechanisms (Foy et al. 1978; Jackson et al. 1990; Mukhopadhyay and Sharma 1991; Barceló and Poschenrieder 1992). This statement is particularly true in the case of heavy metal effects on plant respiration.
