The present invention provides a methyl jasmonate-induced phospholipid nanomaterial from an extract of the adventitious roots of the Chinese yew vine, as well as a preparation method, application, and pharmaceutical composition thereof, relating to the field of biomedical technology. The methyl jasmonate-induced phospholipid nanomaterial from an extract of the adventitious roots of the Chinese yew vine provided by the present invention comprises an extract of the adventitious roots of the Chinese yew vine induced by the methyl jasmonate and a phospholipid bonded to the surface of the extract of the adventitious roots of the Chinese yew vine induced by the methyl jasmonate. The present invention bonds the extract of the adventitious roots of the Chinese yew vine induced by the methyl jasmonate with the phospholipid, thereby greatly improving the stability, water solubility, bioavailability, and pharmacological activity of the extract of the adventitious roots of the Chinese yew vine induced by the methyl jasmonate, and having excellent anti-inflammatory and anti-tumor activities. The phospholipid has low toxicity, and the methyl jasmonate-induced phospholipid nanomaterial from the adventitious roots of the Chinese yew vine induced by the methyl jasmonate is highly safe. The methyl jasmonate-induced phospholipid nanomaterial from the adventitious roots of the Chinese yew vine induced by the methyl jasmonate is a nanoscale biomaterial that greatly improves the efficiency of drug delivery.

The invention provides application of geranyl linalool to inhibition of growth of lateral roots of notopterygium incisum seedlings and / or breeding of notopterygium incisum superior seedlings, and belongs to the technical field of planting of wild notopterygium incisum seedlings. In the invention, the geranyl linalool can promote the elongation of the roots of the notopterygium incisum seedlings and inhibit the formation of lateral roots by increasing the content of auxin in the notopterygium incisum seedlings and reducing the contents of jasmonic acid, abscisic acid and 1-aminocyclopropane-1-carboxylic acid (an ethylene synthesis precursor). Moreover, the geranyl linalool can also improve the activity of polyphenol oxidase and urease in rhizosphere soil, improve the activity of nitrate reductase and glutamine synthetase in leaves, improve the content of alkali-hydrolyzable nitrogen in soil, reduce the content of total phenolic acid in soil and promote conversion of ammonium nitrogen into nitrate nitrogen, so that nitrogen absorption and utilization are promoted, and growth and shape optimization of seedlings are facilitated. In addition, the geranyl linalool can also improve the abundance of rhizosphere soil probiotic bacteria and reduce the abundance of rhizosphere soil pathogenic fungi, so that the disease resistance of the notopterygium incisum seedlings is improved.

This disclosure provides a method for alleviating the damaging effects of D. maidis in corn crops, which involves the use of plant defense elicitors such as jasmonates and salicylates.

The invention provides a function and application of JAVL in regulation and control of cotton gland development and phytoalexin biosynthesis. The invention discloses a pigment gland specific gene JAVL (Jasmonate-associated VQ motif-like gene) containing a protein for coding a VQ structural domain, and the pigment gland specific gene JAVL can be used for regulating the size of the pigment gland and the biosynthesis of jasmonates and other plant defense compounds. The invention provides a new action target for improving the disease resistance of plants.

The invention provides a preparation method of a siraitia grosvenorii-jasmine flower tea plant beverage, which comprises the following steps: sterilizing siraitia grosvenorii concentrated juice and jasmine flower concentrated juice, feeding into a reaction kettle, shearing and uniformly mixing with high-temperature sterile water at a high speed, rapidly cooling, and feeding into a negative-pressure filling machine for subpackaging to obtain a final product. Wherein the jasmine flower concentrated solution activates flower fragrance prerequisite substances through low-temperature enzymolysis, volatile fragrance and non-volatile substances are efficiently extracted respectively in combination with gradient variable-temperature extraction, and finally, the fragrance intensity of the extract liquid is improved by adopting a cyclodextrin embedding technology. The prepared plant beverage adopts triple aroma locking, so that the retention rate of key aroma components linalool and jasmine ketone of a final product is increased, and the flavor of the final product is improved.
