![]() In addition, the microbial diversity was associated with specific meteorological parameters, implying that there was a connection between the environmental conditions of the vineyard and the microbial distribution pattern such as the fungus genus Filobasidium was positively correlated with relative humidity and negatively correlated with average high temperature, average low temperature, and average ground temperature the bacterium genus Lactobacillus was positively correlated with sunlight time, and negatively correlated with relative humidity. Epidermal microorganisms recruited members according to their developmental stages, but retained the core taxa, such as the fungi genera Alternaria, Jattaea, and Jattaea and the bacteria genera Brevundimonas, Sphingomonas, Acinetobacter, and Pseudomonas. ![]() The results showed that the diversity of fungi and bacteria decreased during development. In this study, high-throughput amplicon sequencing technology was used to perform ITS and 16S sequencing of Cabernet Sauvignon epidermal microbes at different developmental stages in the Wuhai region to investigate the succession of epidermal microbes and their response to developmental stages and vineyard weather. However, the diversity of epidermal microorganisms during the development of berries under the ecological viticulture model has not been described in detail. Grapevine-related microorganisms affect the health and yield of grapes, the metabolic pathways of the fermentation process, and the regional characteristics of wine. 3China Wine Industry Technology Institute, Zhongguancun Innovation Center, Yinchuan, China.2Shaanxi Engineering Research Center for Viti-Viniculture, Xianyang, China. ![]() 1College of Enology, Northwest A&F University, Xianyang, China. ![]() Ru-teng Wei 1†, Ning Chen 1†, Yin-ting Ding 1, Lin Wang 1, Fei-fei Gao 1, Liang Zhang 1, Yi-hui Liu 1, Hua Li 1,2,3*‡ and Hua Wang 1,2,3*‡ ![]()
