Symptoms of sorghum start before and after heading. At the beginning, red or purple to light brown spots were formed on the leaves, followed by the expansion of pathogenic bacteria, and the spots expanded to form an oval-shaped bulge on the surface of the leaves of the uredia spores. The cracks revealed brownish-white powder, ie, summer spores. In the later period, the teliospore was formed in the original place. The teliospore was darker and had a larger shape than the summer spores. Pathways and Pathogens Germs pass winter through winter spores on sick bodies, in soil, or on other hosts. When the conditions are suitable for the following year, the spores of the winter spore germinate and invade the young leaves to form a sexual organ, and then a rust generator is generated on the back of the lesion. After the rust spores spread in the device, they germinate when there is water on the leaves, and they also invade from the leaves. The uredia spores and summer spores were formed, and the spores of the summer were spread by airflow and reinfected several times. When the sorghum approaches harvest, it forms a teliospore in the area where the uredia spores are produced, and winterizes with the teliospores. The July-August rainy season is prone to disease.
Collagen is a triple helical protein which can be considered as the bio-glue inside our body; in fact, animal glue can be obtained by boiling the animal skin. Collagen, a major component of connective tissues, exits in the extracellular space of these tissues which are the key reinforcing and bonding materials for all tissues and organs throughout our body, forming rigid structures as such bone, semi-rigid tissues such as cartilage, or soft tissues such as muscle, tendon, skin, ligaments, and cell membranes, etc. There are different forms (fibrillar and non- fibrillar) and types of collagens in the body; Type 1 being the major type constitutes over 90% in our body and is the major component in skin, tendon, vascular ligature, organs, bone (main component of the organic part of bone). Because collagen is an essential building material of all tissues and organs, it has many medical uses, such as in cardiac (hear) applications, cosmetic surgery, bone grafts, tissue regeneration, reconstructive surgical uses, and wound healing care.
Collagen is created inside fibroblast cells, and this process is needed to support the creation and repair of the body`s connective tissues. However, the biological process starts to breakdown when we are aging, normally after we reach the age of late 20s or early 30s. Because collagen from natural sources such as animal, fish scales or plant contain essentially the same amino acid compositions (glycine, proline, alanine, hydroxyproline, glutamic acid, arginine, aspartic acid, serine, lysine, leucine, valine, threonine, phenylalanine, isoleucine, etc.) as human collagen, supplement the body with the natural collagen, either by dermal application or through oral ingestion, can help rejuvenate collagen creation process to support the repairing of aging connective tissues in our body, particularly those in our skin, and to reverse or slow down the aging process for a more youthful appearance.

The pathogen Puccinia sorghi Schwl described Puccinia corniculatus and Puccinia purpurea Cooke as purple shank rust or Puccinia tenuifolia, both belong to Basidiomycotina fungi. The former refers to corn rust. P. The purpurea summer spores are piled on the lesions on both sides of the leaf, chestnut-brown, surrounded by sticks or head-like lateral filaments. Side wire brown. Summer spores nearly spherical or pear-shaped, size 24-4420-29 (um), with tumor-like thin thorns, dark brown wall, with 5-10 bud hole. The winter spores grow on both sides of the leaf and are 1-3 mm long and red-brown. The teliospores are oval in length, 36-5424-32 (um) in size, rounded at the top, and slightly shrunk at the sides, with a 2-3 mm thick sidewall and dark brown.
