Excessive resistance of KCB-1 to bacterial wilt
We carried out DI statistical evaluation within the area for CB-1, KCB-1 and YY97, which have been planted three rows with 20 crops in every row. The outcomes confirmed that the DI of YY97 was considerably smaller than that of CB-1 (p < 0.001) (Fig. 2a–d). the DI of KCB-1 was considerably smaller than that of YY97 and CB-1 (p = 0.03, p < 0.001) (Fig. 2a–d).

Alpha and PCA evaluation of KS, GS and BS in 4 areas
Alpha variety refers back to the variety of species in a area. We used Chao1 and Shannon to evaluate the abundance and variety of rhizosphere bacterial communities in three soils from 4 areas, respectively. Chao1 was not considerably completely different for KS and GS in Xuancheng, Luzhou, Huanxi and Yibin (Pupil’ t take a look at, p = 0.65, p = 0.72, p = 0.32 and p = 0.65) (Fig. 4a–d). Nevertheless, Chao1 of KS and BS have been considerably completely different in Luzhou and Huanxi, respectively (Pupil’ t take a look at, p = 0.03, p < 0.001) (Fig. 4b,c). As well as, Chao1 was additionally considerably completely different between GS and BS in huanxi (p = 0.01) (Fig. 4c).

The info inside every group for (a–h) and (i–l) have been statistically analyzed by Pupil’ t take a look at and PERMANOVA, respectively (*: 0.01 < p ≤ 0.05, **: 0.001 < p ≤ 0.01, ***: p ≤ 0.001).
As well as, the shannon of KS and BS, KS and GS of Xuancheng weren’t considerably completely different (Pupil’ t take a look at, p = 0.86, p = 0.07) (Fig. 4e), respectively. Nevertheless, there was a big distinction in shannon between GS and BS (Pupil’ t take a look at, p = 0.04) (Fig. 4e). The shannon of KS and BS, KS and GS, GS and BS in luzhou weren’t considerably completely different (Pupil’ t take a look at, p = 0.35, p = 0.06, p = 0.66) (Fig. 4f). The shannon of KS and BS, GS and BS of Huanxi have been considerably completely different (Pupil’ t take a look at, p = 0.002, p = 0.01) (Fig. 4g), respectively. Nevertheless, the shannon of GS and KS weren’t considerably completely different (Pupil’ t take a look at, p = 0.73) (Fig. 4g). The shannon of KS and BS of Yibin have been considerably completely different (Pupil’ t take a look at, p = 0.03) (Fig. 4h), respectively. Nevertheless, the shannon of GS and BS, GS and KS weren’t considerably completely different (Pupil’ t take a look at, p = 0.10, p = 0.66) (Fig. 4h), respectively.
We carried out PCA evaluation of the bacterial communities of KS, GS and BS in Xuancheng, Luzhou, Huanxi and Yibin. As well as, we used physiological indicators resembling pH, AN, AP, AK and SOC of the three rhizosphere soils within the 4 areas as covariates for PCA. The physiological indicators of the three rhizosphere soils within the 4 areas are proven in Fig. S2. The outcomes confirmed that the bacterial group of BS was considerably completely different from that of KS and GS in Xuancheng, Luzhou, Huanxi and Yibin, respectively (PERMANOVA, p = 0.002, p = 0.003, p = 0.009 and p = 0.001). In distinction, there have been no vital variations in bacterial group composition between KS and GS within the three areas, aside from Luzhou. (Pupil’ t take a look at, p = 0.55, p = 0.44 and p = 0.13). As well as, to additional analyze the connection between environmental elements, rhizosphere soil samples and rhizosphere bacterial communities within the 4 areas, we carried out an evaluation utilizing RDA/CCA. The outcomes confirmed that pH, AN, AP and SOC had a larger impact on the bacterial group in Xuancheng, whereas AK had a smaller impact on the bacterial group in Xuancheng (Fig. 4i). As well as, the bacterial group of GS in Xuancheng was negatively correlated with pH, AN and SOC, whereas the bacterial group of KS was positively correlated with pH, AN, AP and SOC (Fig. 4i). In Luzhou, pH, AN, AP, AK and SOC have been all positively correlated with bacterial communities in KS, whereas they have been negatively correlated with GS (Fig. 4j). In Huanxi, pH, AN, AP, AK and SOC had related results on KS and GS (Fig. 4ok). In Yibin, pH, AN, AK, AP and SOC have been positively correlated with the bacterial group of KS, whereas pH, AN, SOC have been negatively correlated with the bacterial group of KS (Fig. 4l). To additional examine the diploma of rationalization of variations in KS, GS and BS bacterial communities within the 4 areas by soil physicochemical indicators. We additionally carried out PERMANOVA evaluation for every of the three soils within the 4 areas. The outcomes confirmed that AN, AK, SOC, pH and AP defined 0.15 (p = 0.002), 0.12 (p = 0.002), 0.13 (p = 0.002), 0.12 (p = 0.002) and 0.09 (p = 0.003) of the variations within the rhizosphere bacterial communities of the three soils within the 4 areas, respectively.

Along with Xuancheng, the helpful genera current within the KS of Yibin, Luzhou and Huanxi had extra interactions. For instance, Micromonospora and Sphingomonas within the KS of Yibin, Rhodanobacter, Sphingomonas and Streptomyces within the KS of Luzhou and Sphingomonas within the KS of Huanxi (Desk S3).
PICRUSt practical predictive evaluation
PICRUSt perform was predicted for 60 samples from 4 areas. The outcomes confirmed that the COG capabilities have been comparatively related in all samples. All of the colonies have been concerned in RNA processing and modification, chromatin construction and dynamics, power manufacturing and conversion, cell cycle management, cell division, chromosome partitioning, amino acid transport and metabolism, and so on.
