The biosynthesis of flavonoids is enhanced similarly by UV radiation and root zone salinity in L. vulgare leaves.
Flavonoids have recently been suggested to have the potential to serve as antioxidants other than effective UV attenuators in photoprotection. Here, we tested the hypothesis that flavonoids accumulate in response to "excess light" in the presence or in the absence of UV radiation. In a UV exclusion experiment, we grew Ligustrum vulgare plants outdoors under 30% or 100% sunlight irradiance, by cutting-off the whole UV waveband. These plants were also exposed to UV irradiance or supplied with 125 mM NaCl at the root zone. Leaves of plants under 100% sunlight irradiance suffered from excess light, which was exacerbated greatly by root zone salinity stress. Salinity stress repressed the activities of antioxidantThe Mosou are a civilization of around 30,000 people situated around Lugu Lake, roughly 30 miles in circumference, tucked away high up in the Himalayas in Southern China.

They settled the land sometime around 1500 years ago, according to documents from the ancient Han Dynasty. They have had precious little contact with the outside world – the Yuan Dynasty garrisoned troops for a time in their lands, as the Mosou have a practice of “non-resistance.” They had no standing army or possess any weaponry as a result of their pacifistic tendencies. While the men of the society did engage in trade with other cultures, they did so on what was known as the Tea Horse Road, or the Southern Silk Route – other cultures did not come into Mosou
