UV-B promotes flavonoid biosynthesis in by inducing the -- module.

(ginkgo) leaves have medicinal value due to their high levels of secondary metabolites, such as flavonoids. We found that the flavonoid content in ginkgo leaves increases significantly at high altitudes (Qinghai-Tibet Plateau). Considering that high UV-B radiation is among the key environmental characteristics of the Qinghai-Tibet Plateau, we carried out simulated UV-B treatments on ginkgo seedlings and found that the flavonoid content of the leaves increased significantly following the treatments.

Genome-Wide Identification, Evolutionary and Functional Analyses of WRKY Family Members in .

WRKY transcription factors (TFs) are one of the largest families in plants which play essential roles in plant growth and stress response. is a living fossil that has remained essentially unchanged for more than 200 million years, and now has become widespread worldwide due to the medicinal active ingredients in its leaves. Here, 37 WRKY genes were identified, which were distributed randomly in nine chromosomes of .

Lung-function trajectories in COVID-19 survivors after discharge: A two-year longitudinal cohort study.

Background: Data on the long-term trajectories of lung function are scarce in COVID-19 survivors.

Methods: We re-analyzed the data from a prospective longitudinal cohort follow-up study of COVID-19 survivors over 2 years after infection. All participants were divided into scale 3, scale 4 and scale 5-6 groups according to seven-category ordinal scale.
