Impact of High Light Intensity and Low Temperature on the Growth and Phenylpropanoid Profile of .

Exposure to high light intensity (HL) and cold treatment (CT) induces reddish pigmentation in , an aquatic fern. Nevertheless, how these conditions, alone or in combination, influence growth and pigment synthesis remains to be fully elucidated. Likewise, the regulatory network underpinning the accumulation of flavonoids in ferns is still unclear.

Exposure to different light intensities affects emission of volatiles and accumulations of both pigments and phenolics in Azolla filiculoides.

Many agronomic trials demonstrated the nitrogen-fixing ability of the ferns Azolla spp. and its obligate cyanobiont Trichormus azollae. In this study, we have screened the emission of volatile organic compounds (VOCs) and analyzed pigments (chlorophylls, carotenoids) as well as phenolic compounds in Azolla filiculoides-T.

Light and Temperature Shape the Phenylpropanoid Profile of Fronds.

is a genus of floating freshwater ferns. By their high growth and N fixation rates, species have been exploited for centuries by populations of South-east Asia as biofertilizers in rice paddies. The use of species as a sustainable plant material for diverse applications, such as feeding, biofuel production, and bioremediation, has encountered a growing interest over the last few years.
