Based on the study of typical selenium-rich soil in the middle area of Zhejiang province, the influencing factors of selenium contents were summarized. We found that the selenium contents were controlled by the geological background. It was much higher in Tangxi, Zhijiang, and Jinhua than in other geological background regions. In addition, the contents of selenium in soil under different land use types showed a great difference. The content in the dry land was much more enriched than that in the paddy field. Further research showed that selenium was closely related to soil organic matter because of its adsorption and fixation. Moreover, we found that the soil texture was another important influencing factor. Selenium contents increased with increasing content of clay in the soil.

Selenium promotes plant growth and improves nutritional quality, and the role of nano-selenium in alfalfa in regulating nutritional quality is unknown. In this study, using the N labeling method, it was found that nano-selenium could promote plant nitrogen metabolism and photosynthesis by increasing the light energy capture capacity and the activities of key enzymes of the nitrogen metabolism process, leading to an increase in alfalfa nitrogen accumulation and dry matter content. The transcriptome and metabolome revealed that nano-selenium mainly affected the pathways of 'biosynthesis of amino acids', 'starch and sucrose metabolism', 'pentose and glucuronate interconversions', 'pentose phosphate pathway', and 'flavonoid biosynthesis'.

Objective Of The Review: Edible mushrooms are found to be foods with high nutritional content, which have been shown to be more widely used ingredients in cooking in traditional dishes. This article explores the rising trend in the use of edible mushrooms in new formulations of functional foods, taking advantage of their properties and benefits in human health.
Recent Findings: The use of mushrooms as an ingredient in new or modified food formulations is driven by solid evidence of their nutritional content and bioactivity.
