“…In contrast to the increase of TN, soil NH 4 + , and NO 3 – contents in continuous tea nursery soils were significantly reduced ( Table 1 ). This is most likely due to the inhibitory effect of polyphenols on key processes of the N cycle including nitrification and N mineralization ( Bradley et al, 2000 ; Tang et al, 2021 ), which was also verified by the results of functional changes in bacterial community ( Figures 4E , 6A ). In exception to soil nutrients, a significant negative correlation between polyphenols and soil pH was also observed in our research ( Figure 7 ).…”

“…Further examination showed that the Firmicutes genus Bacillus was among the most abundant rhizosphere‐enriched taxa. Soil Bacillus positively responds to the increased levels of epigallocatechin gallate, a bioactive compound from tea plants (Tang et al ., 2021 ). Moreover, the phylum Bacteroidetes exhibited higher abundance in the phyllosphere than other compartments, which was also reported in sugar maple ( Acer saccharum ) and a seagrass species (Tarquinio et al ., 2019 ; Wallace et al ., 2018 ).…”

“…Tea is a perennial woody crop and has been domesticated and cultivated as a beverage plant for a long history (Xia et al ., 2020b ). Tea plants are featured by diverse secondary metabolites and maintain beneficial or pathogenic relationships with diverse microorganisms (Bag et al ., 2022 ; Tang et al ., 2021 ; Xie et al ., 2020 ). Until recently, the high‐quality reference genome of tea ( Camellia sinensis ) has been reported (Wang et al ., 2020 ; Wei et al ., 2018 ; Xia et al ., 2020a ; Zhang et al ., 2020 ), which opens up new possibilities for tea studies from a genome‐wide view.…”

“…The NanoDrop 2000 spectrophotometer (Thermo Scienti c, Waltham, MA, USA) was used to analyse the concentration and quality of the extracted DNA. The V4-V5 regions of 16S rRNA genes were ampli ed using primers 515F (5′-GTGCCAGCMGCCGCGGTAA-3′) and 907R (5′-CCGTCAATTCMTTTRAGTTT-3′) (Tang et al, 2021a). Primers ITS1-F (5′-CTTGGTCATTTAGAGGAAGTAA-3′) and ITS2-2043R (5′-GCTGCGTTCTTCATCGATGC-3′) were used to amplify the ITS1 region.…”
