General Information

General Information Comment Organism
malfunction exposure to phenanthrene, a model compound for polycyclic aromatic hydrocarbon (PAH) stress, leads to enhancement of both chlorophyll synthesis and degradation, but the degradation rate is faster. Phenanthrene accumulation has significant and positive effects on increase of glutamate, 5-aminolevulinic acid, uroporphyrinogen III, protoporphyrin IX, Mg-protoporphyrin IX and protochlorophyllide concentrations. Over the exposure time, wheat leaf color turns light. With the accumulation of phenanthrene, the concentrations of glutamate, 5-aminolevulinic acid, uroporphyrinogen III, protoporphyrin IX, Mg-protoporphyrin IX and protochlorophyllide increase while the concentrations of porphobilinogen and Chlorophyll b decrease. Also chlorophyll a content rises initially and then declines. Uroporphyrinogen III synthase and chlorophyllase are activated and porphobilinogen deaminase activity declines in the treatments. There is a negative correlation between phenanthrene accumulation and total chlorophyll. Toxicity of PAHs to plants and crop PAH-adaptive mechanism in the environment, overview. With increasing phenanthrene accumulation in wheat leaves, the growth of wheat leaves is inhibited, and mature wheat leaf color turns light Triticum aestivum
