Possible Interaction: Carotenoids and Selenium

“Treatments with Se positively affected total chlorophylls and carotenoids , and leaf stomata dimensions.”

“The concentrations of total chlorophyll, total pheophytin, and carotenoids were negatively affected in genotypes Obatã, IPR99, and IAC125 upon exposure to Se at 1 mmol L-1.”

“ Selenium application up to 40 mg L-1 increased the concentration of photosynthetic pigments such as chlorophylls, pheophytins and carotenoids in coffee leaves.”

“ Selenium treated plants showed a dramatically decrease of soluble proteins, chlorophylls, and carotenoids concentration, resulting in the visual symptoms of toxicity characterized as leaf chlorosis and necrosis.”

“ Carotenoids increased by 16% in sprouts treated with 1.0 mg/100 g selenium compared to their counterparts without selenium.”

“While there was no change in the ripening indexes and the production of olives generally, Se application did increase the total Se, Se methionine, phenol, and carotenoid and chlorophyll contents.”

“However, Se supplementation reduced total carotenoids and total soluble solid (TSS) concentrations in the pepper fruits exposed to Cd.”

“ Selenium (0.01-0.05 g kg⁻¹) significantly increased chlorogenic acid, chlorophyll and carotenoids by 200-400% and reduced rutin by 400-900%.”

“ Selenium significantly increased chlorogenic acid, chlorophyll a, chlorophyll b and carotenoids , hence increasing the medicinal value of L. chinense leaves.”

“It was observed that incorporation of selenium into yeast cells during the growth inhibited production of β‐carotenoid and other carotenoid precursors (torularhodin and torulene).”

“ Carotenoids (beta-carotene and xanthophylls) and chlorophyll (Chl a and Chl b) contents in cells exposed to Se 50 mg/L increased primarily and decreased afterwards, while photosynthetic pigments in cells exposed to Se 800 mg/L decreased significantly.”
