Expression

Organism Comment Expression
Nicotiana tabacum enzyme expression is induced by salt (300 mM NaCl), drought, and exogenous abscisic acid treatments up

General Information

General Information Comment Organism
malfunction the suppression of enzyme expression leads to lower expression levels of genes in the carotenoid biosynthesis pathway and to reduced accumulation of carotenoids, chlorophyll, and abscisic acid Nicotiana tabacum
metabolism the cyclization enzyme is involved in carotenoid accumulation Nicotiana tabacum
physiological function the enzyme confers salt and drought stress tolerance in Nicotiana tabacum Nicotiana tabacum
