“…These compounds not only enhance the efficiency of fertilizers and pesticides, but also create a protective film on the plant surface. This layer not only helps prevent damage to cellular membranes caused by high-temperature stress, but also improves plants' antioxidant capacity [15][16][17][18]. Despite these benefits, further research is necessary to determine whether a combination of small peptides and surfactants could more effectively enhance tea plants' resistance to high-temperature stress.…”

Tea plants are highly susceptible to the adverse effects of a high-temperature climate, which can cause reduced yield and quality and even lead to plant death in severe cases. Therefore, reducing the damage caused by high-temperature stress and maintaining the photosynthetic capacity of tea plants is a critical technical challenge. In this study, we investigated the impact of small oligopeptides (small peptides) and surfactants on the high-temperature-stress tolerance of tea plants. Our findings demonstrated that the use of small peptides and surfactants enhances the antioxidant capacity of tea plants and protects their photosynthetic system. They also induce an increase in gibberellin (GA) content and a decrease in jasmonic acid (JA), strigolactone (SL), auxin (IAA), and cytokinin (CTK) content. At the same time, small peptides regulate the metabolic pathways of diterpenoid biosynthesis. Additionally, small peptides and surfactants induce an increase in L-Carnosine and N-Glycyl-L-Leucine content and a decrease in (5-L-Glutamyl)-L-Amino Acid content, and they also regulate the metabolic pathways of Beta-Alanine metabolism, Thiamine metabolism, and Glutathione metabolism. In summary, small peptides and surfactants enhance the ability of tea plants to resist high-temperature stress.

“…Rhamnolipid and sophorolipid are non-toxic, harmless, edible, and degradable biosurfactants that are commonly employed in conjunction with foliar fertilizers to enhance their e cacy [10][11][12][13]. Rhamnolipid is a biological metabolic substance produced by Pseudomonas or Burkholderia, which exhibits inhibitory effects on the growth and reproduction of certain plant pathogenic bacteria and fungi.…”

Background: Small peptides play a crucial role in plant growth and adaptation to the environment. Exogenous small peptides are often applied together with surfactants as foliar fertilizers, but the impact of small peptides and surfactants on the tea phyllosphere microbiome remains unknown. Results: In this study, we investigated the effects of small peptides and different surfactants on the tea phyllosphere microbiome using 16s and ITS sequencing. Our results showed that the use of small peptides reduced the bacterial diversity of the tea phyllosphere microbiome and increased the fungal diversity, while the use of surfactants had a suppressive effect on both bacterial and fungal diversity. Furthermore, the addition of rhamnolipid to small peptides significantly improved the tea phyllosphere microbiome community structure, making beneficial microorganisms such as Pseudomonas, Chryseobacterium, Meyerozyma, and Vishniacozyma dominant populations. Conclusion: Our study suggests that the combined use of small peptides and surfactants can significantly modify the tea phyllosphere microbiome community structure, particularly for beneficial microorganisms closely related to tea plant health. Thus, this study provides a reference for the application of small peptides and surfactants in agricultural production, which can be used to regulate the phyllosphere microbiome community in tea plant management.
