Optimizing sweet potato production: insights into the interplay of plant sanitation, virus influence, and cooking techniques for enhanced crop quality and food security

Unveiling the Role of Sweet Potato Root in Skin Health: A New Approach to Collagen Synthesis and Rejuvenation

Collagen synthesis is inextricably linked to skin health and is necessary for maintaining the skin's suppleness, structure, and general youthfulness. Wrinkles and loss of skin firmness are due to a reduction in collagen synthesis with age. The interest in dermatology lies in natural substances that promote collagen synthesis and prevent skin aging. Rich in bioactive compounds such as beta-carotene, anthocyanins, and flavonoids, the root of sweet potato could be seen to offer the potential to enhance skin health. The review paper discusses the antioxidant and anti-inflammatory properties of the root that protect the skin from oxidative stress and inflammation and delves into its use as a natural collagen formation and rejuvenation agent for the skin. Such in vitro and in vivo experiments and clinical studies provided experimental data on the effectiveness of this food supplement in skin health and collagen production. In addition, this review explored the role of natural sweet potato root, for instance, through the mechanism of sweet potato extract containing resveratrol in promoting skin health. This opens a chance for discussing the implications that supplements from the root of the sweet potato might make if orally administered and applied topically to improve health conditions for the skin.

Effects of Perillaldehyde and Polyamines on Defense Mechanisms of Sweet Potatoes against Ceratocystis fimbriata

Sweet potato (Ipomoea batatas) serves as a significant food and economic crop worldwide. However, its production and safety are jeopardized by black rot, a disease caused by Ceratocystis fimbriata. Although polyamines (PAs) are common biological growth factors, their function in the storage of fruits and vegetables remains poorly understood. This study examines the physiological roles of both exogenous and endogenous PAs in C. fimbriata, particularly their metabolism via gene knockout techniques. Additionally, we assessed how exogenous PAs affect sweet potato storage resistance. Our findings reveal that PAs are crucial in managing oxidative and cell wall stress in C. fimbriata. At high concentrations, PAs displayed cytotoxic effects through the upregulation of nitric oxide synthase (TAH18). Furthermore, exogenous PAs significantly enhanced the defense mechanisms of sweet potatoes during storage. The concurrent use of perillaldehyde (PAE), a natural antibacterial compound, additionally decreased the incidence of black rot in sweet potatoes. This study provides a novel strategy and theoretical basis for the prevention and control of fungal diseases in stored fruits and vegetables.
