Corydalis yanhusuo, a precious herb of the Papaveraceae family, is widely used in multiple traditional Chinese medicines for the treatment of many painful conditions, and its medicinal part is the dried tuber. Yet how to improve this plant’s medicinal yield as well as its economic efficiency remains a key problem in its cultivation. The planting of C. yanhusuo in rotation with peanut (Arachis hypogaea L.) aims to improve land utilization efficiency, but the total production of tubers is severely reduced relative to fields without rotation. However, an increased yield was observed in C. yanhusuo plants grown in previously flooded fields (HR field) compared to the ones grown in the fields that had been used to cultivate peanut (PL field) or in fields without rotation or flooding (N field). Based on these phenomena, in this study, we explored the potential factors responsible for the altered growth/yield of C. yanhusuo under different field conditions. Soil physicochemical properties and the diversity and community of rhizobacteriome of C. yanhusuo were both analyzed. By testing several soil physicochemical properties, we found that the cation exchange capacity (CEC), soil organic matter (SOM), total nitrogen (TN), and pH value differed significantly among these three types of fields. 16S rRNA amplicon sequencing revealed stark differences in the composition, diversity, and potential functions of the bacterial community in the rhizosphere of C. yanhusuo plants grown in field with the peanut rotation or flooding. Notably, the Acidobacteria were enriched in the HR field, while Actinobacteria were enriched in the PL field. More importantly, further analysis showed that changed soil physicochemical properties could be one reason for why the rhizospheric bacterial community has changed; hence, soil physicochemical properties might also be affecting plant performance indirectly by regulating the rhizospheric bacterial community. The RDA analysis distinguished CEC as the most important soil physicochemical property influencing the structure and composition of the C. yanhusuo rhizobacteriome. In summary, our results suggest peanut rotation- and flooding-induced soil physicochemical properties changes would further impact the rhizobacteriome of C. yanhusuo albeit differentially, culminating in opposite effects upon the plant growth and medicinal yield of C. yanhusuo.

AbstractBacterial wilt as a soil-borne disease was caused by Ralstonia solanacearum, and seriously damages the growth of tobacco. Integrated biocontrol method was explored to control bacterial wilt. Nevertheless, the long-term effects of the integrated biocontrol method on soil bacterial community, soil physicochemical properties and the incidence of bacterial wilt are not well understood. In this study, B. amyoliquefaciens ZM9, calcium cyanamide and rice bran were applied to tobacco fields in different ways. The disease index and incidence of tobacco bacterial wilt (TBW), soil physicochemical properties, colonization ability of B. amyoliquefaciens ZM9, and rhizopshere bacterial community were investigated. The results showed that the integrated application of B. amyoliquefaciens ZM9, rice bran and calcium cyanamide had the highest control efficiency of TBW and bacteria community diversity. Additionally, the integrated biocontrol method could improve the colonization ability of B. amyoliquefaciens ZM9. Furthermore, the integrated biocontrol method could effectively suppress TBW by regulating soil physicochemical properties, promoting beneficial bacteria and antagonistic bacteria of rhizopshere soil. This strategy has prospect of overcoming the defects in application of a single antagonistic bacteria and provides new insights to understand how to improve the colonization capacity of antagonistic bacteria and control efficacy for TBW.

Pinus sylvestris var. mongolica is an important tree species for ecological construction and environmental restoration owing to its rapid growth rate and excellent stress resistance. Pinus sylvestris var. mongolica sphaeropsis blight is a widespread disease caused by Sphaeropsis sapinea. This study was focused on non-infected (CK) and infected (SS) Pinus sylvestris var. mongolica plants in Zhanggutai area, Liaoning Province, China. Illumina high-throughput sequencing based on the templates of sequencing-by-synthesis working with reversible terminators is a widely used approach. In the present study, systematic differences in relationships among rhizosphere soil physicochemical properties, bacterial community structure, diverse bacterial genera, and alpha diversity indices between the two categories were evaluated. The current findings are as follows: (1) Shannon’s index of SS soil was significantly higher than CK, and it was significantly lower in May than July and September (p < 0.05). (2) Non-metric multidimensional scaling (NMDS) showed a difference in bacterial community structure during May (spring), July (summer), and September. (3) At the phylum level, no significant difference was found in the bacterial genera between CK and SS soil for three seasons; however, at the genus level, there were about 19 different bacterial genera. The correlation studies between 19 different bacterial genera and environmental factors and α-diversity indicated that bacterial genera of non-infected and infected Pinus sylvestris var. mongolica were distributed differently. The bacterial genera with CK were positively correlated with soil physicochemical properties, while a negative correlation was found for SS. In conclusion, the differences in nutrient and microbial community structure in the rhizosphere soil of Pinus sylvestris var. mongolica are the main causes of shoot blight disease.

Abstract:In this paper, we studied the influence of soil physicochemical factors on the distribution of Cordyceps. We found that in the soil layers at different depths, the differences in pH values, total N (TN), total P (TP), available P (AP) and available K (AK) were not significant, but the differences in soil water content (WC), soil organic matter (OM), hydrolysable nitrogen (HN) and AK were significant. In the 5-10 cm layer, WC, pH and TP were significant factors that influence the distribution of Cordyceps - the number of Cordyceps was the largest and the characterization of the Cordyceps was also the best. TP was an important factor for the first principle component of the soil physicochemical properties that influenced the population distribution of Cordyceps. pH value was an important factor for the the second principal component of the soil physicochemical properties that influenced population distribution, and WC was an important factor for the third principal component, the soil physicochemical properties. This demonstrates that the requirement of Cordyceps for specific ranges of WC, soil acidity-alkalinity and AP in soil layers is very high.

Ferula Sinkiangensis

Abstract Background Ferula sinkiangensis is a desert short-lived medicinal plant, and its number is rapidly decreasing. Rhizosphere microbial community plays an important role in regulating global biogeochemical cycle, plant growth and adaptability. However, the Ferula sinkiangensis bacterial community and the processes that drive its assembly remain unclear. Results In this study, based on Illumina HiSeq high-throughput sequencing, we explored the diversity, structure and composition of Ferula sinkiangensis rhizosphere bacterial communities at different slope positions (upper, middle and bottom) and soil depths (0-10 cm, 10-25 cm, 25-40 cm) and their correlation with soil physicochemical properties. Actinobacteria (22.7%), Proteobacteria (18.6%), Acidobacteria (14.0%), Gemmatimonadetes (10.1%), Cyanobacteria (7.9%), Bacteroidetes (6.9%), Planctomycetes (3.9%), Verrucomicrobia (3.5%), Firmicutes (3.4%) and Chloroflexi (3.2%) were the dominant bacterial phyla in Ferula sinkiangensis rhizosphere soil. Variance analysis showed that the diversity and abundance of rhizosphere bacterial community in Ferula sinkiangensis were significantly different at various slope positions and soil depths. Specifically, the diversity of bacterial community was significantly higher at the top than the bottom of the slope, and the diversity and richness of bacterial community were significantly greater in the 0-10cm than the 25-40cm soil layer. Linear discriminant effect size (LEfSe) analysis showed the specific phyla and genera of bacteria affected by slope position and soil depth. For example, Planctomycetes, Sphingomonas , Rubrobacter and Adhaeribacter by slope position and significant impact on soil depth. In addition, distance-based redundancy analysis (db-RDA) and variance analysis showed that soil physicochemical factors jointly explained 29.81% of variation in Ferula sinkiangensis rhizosphere bacterial community structure. There was a significant positive correlation between available phosphorus（AP）and the diversity of Ferula sinkiangensis rhizosphere bacterial community ( p < 0.01), whereas pH largely explained the variation of Ferula sinkiangensis rhizosphere bacterial community structure (5.58%, p < 0.01), followed by altitude (5.53%), total salt (TS, 5.21%) and total phosphorus (TP, 4.90%). Conclusion Our results revealed the heterogeneity and variation trends of Ferula sinkiangensis rhizosphere bacterial community diversity and abundance on a fine spatial scale (slope position and depth) and shed new light on the interaction mechanisms between Ferula sinkiangensis rhizosphere bacterial community and soil physicochemical properties.
