Nanjing Forestry University cooperated with Beijing Forestry University and other institutions to obtain a number of new tree species such as insect pests, drought resistance and salt tolerance, and fast-growing and high-quality transgenic poplars. On June 23rd, the National Project for Research and Industrialization of Genetically Modified Plants shared by Nanlin University and Beilin University passed the acceptance of the expert group of the Ministry of Science and Technology. The GM trees that passed the inspection, in addition to poplars, were also eucalyptus, liriodendron, acacia and tetraploid Robinia pseudoacacia, indicating that China's tree transgenic technology has made new breakthroughs. Professors Zhuge Qiang and Professor Shi Jisen of Nan Lin Dacheng presided over the project of "Research on pest and disease resistance, genetic transformation of poplar, research and industrialization of eucalyptus" and the selection of transgenic new varieties of Liriodendron, Acacia and tetraploid Robinia pseudoacacia. The "Education and Development Project" belongs to the National 863 Major Scientific Research Project. New tree species such as genetically modified poplars that have been bred by experts have demonstrated significant disease resistance, insect resistance, and fast-growing advantages. In order to reduce the lignin in the paper industry pulp, experts have also successfully implemented genetically regulated tree lignin biosynthesis through genetically modified technology: the transgenic variety poplar can increase the content by about 10% on the basis of the original lignin, and can also make lignin biological The synthesis is reduced by about 10%.

Therefore, amino acids are not only essential for human health, but also play an important role in beauty and skin care products.
Amino acids are the basic units of proteins and are essential organic compounds in life. There are about 500 different amino acids in nature, but among the amino acids that make up the proteins of living organisms, 20 are standard amino acids, which are connected in different sequences to form proteinaceous proteins that perform various physiological functions in living organisms.
Amino acids can be divided into the following categories according to their location and function in proteins
1.Essential amino acids
9 amino acids that the body cannot synthesize by itself or the synthesis speed cannot meet the needs, and must be ingest through food, including lysine, tryptophan, phenylalanine, methionine, threonine, isoleucine, leucine, valine and histidine (infants also need histidine).2.Non-essential amino acids
The human body can synthesize by itself and does not need to obtain directly from food, including glutamic acid, aspartate, alanine, serine, glycine, proline, cysteine, etc.3.Conditional essential amino acids
Under specific conditions (such as disease, stress), the human body's synthetic ability is reduced, and additional supplements are needed, such as arginine, glutamine, etc.Amino acids are also widely used in the field of skin care, as skin care ingredients, they mainly have the following effects
1.Moisturizing
Some amino acids such as glycine, alanine, etc. have good hygroscopic properties, which can help the skin retain moisture and enhance its moisturizing ability.2.Repair
Such as arginine, glutamic acid, etc. participate in the repair and regeneration process of skin cells, promoting wound healing.3.Anti-aging
Certain amino acids have antioxidant effects that can help fight free radical damage and slow down skin aging.4.Cleansing
Amino acid surfactants, such as sodium lauryl sarcosine, are commonly used in cleansing products for sensitive skin due to their mild, non-irritating properties.Therefore, amino acids are not only essential for human health, but also play an important role in beauty and skin care products.
