“…However, further long experiments in this ecosystem type are required to determine whether the decrease in Po will eventually lead to P deficiency and become a limiting factor in the P cycle. Among the different soil properties, pH had the highest impact on bacterial community structure (Figure 6 and Table S1), likely owing to the narrow pH range for optimal bacterial growth (Ragot, Huguenin-Elie, Kertesz, Frossard, & Bünemann, 2016;Tian et al, 2020). Similar results were observed in previous studies (Geisseler & Scow, 2014;Zhang, Gao, et al, 2019).…”

Bamboo‐chicken farming (BCF) is a popular bamboo complex management model in Southeast Asia. However, the effects of BCF on phosphorus (P) availability and associated soil microbial communities remain poorly understood. In this study, we compared the soil properties, P fractions, phosphatase activities, and bacterial community compositions in the surface soil (0–20 cm) of a typical BCF system under different grazing densities [represented as distances of 5, 15, 25, 35, and > 60 m (control site) from the henhouse, respectively]. We observed that total P (Pt) accumulation was more rapid than that of SOC and TN with increasing grazing density. Labile and moderately labile P dominated soil P accumulation under BCF. Resin‐Pi, NaHCO3‐Pi, and 1 M HCl‐Pi increased by 100–233%, 83–183%, and 414–1,314%, respectively, compared with the control. The ratio of labile and moderately labile organic P to the Pt content decreased significantly with increasing grazing density from 38.54% (control) to 17.65% (5 m site). Soil phosphatase activity increased with increasing grazing density, suggesting that BCF effectively promoted the mineralization of soil Po. Inorganic P (Resin‐Pi, NaHCO3‐Pi, and 1 M HCl‐Pi) was positively correlated with Flavobacterium, Pseudomonas, and Arthrobacter but negatively correlated with Burkholderia; this highlights the different functional bacteria involved in P cycling. We conclude that BCF generally increased soil P availability and supply capacity, and the changes in P forms were closely related to changes in soil bacterial community composition. The highly labile P and low C : P ratio under high grazing density conditions may cause soil nutrient imbalance and P leaching.

Background: Bamboo-chicken farming (BCF) is a popular bamboo complex management model in Southeast Asia owing to its high economic benefits. However, the effects of BCF on phosphorus (P) availability and the associated microbial communities in soil remain poorly understood. In this study, we compared the soil properties, P fractions, phosphatase activities, and bacterial community compositions in the surface soil (0–20 cm) of a typical bamboo (Phyllostachys praecox)-chicken farming system under different grazing densities (represented as distances of 5, 15, 25, and 35 m from the henhouse, respectively). The variables were also compared with the soil measurements from an adjacent pure bamboo forest without chicken framing (control site).Results: We observed a significant increase in soil pH, cation exchange capacity (CEC), total N (TN), total P (TP), and available potassium (AK) with increasing grazing density, while soil organic carbon (SOC) showed no significant difference between the sites. The total P accumulation of the soil was also more rapid than that of SOC and TN with increasing grazing density. Labile P and moderately labile P dominated the soil P accumulation under BCF. In particular, Resin-Pi (labile P), NaHCO3-Pi (labile P), and 1 M HCl-Pi (moderately labile P) increased by 100–233%, 83–183% and 414–1314%, respectively, compared with the control values. In contrast, the contribution of labile or moderately labile organic phosphorus to the total phosphorus (Pt) content decreased significantly with increasing grazing density from 38.54% (control) to 17.65% (5-m site). Phosphatase activity also increased with increasing grazing density, which suggests that BCF effectively promoted the mineralization of soil Po. A redundancy analysis showed that the changes in bacterial community structure were closely related to Resin-Pi and 1 M HCl-Pi (r2 = 0.938 and 0.958, respectively). The relative abundances of the phosphobacteria Flavobacterium, Pseudomonas, Streptomyces, and Arthobacter increased with increasing grazing density, while the abundance of Burkholderia decreased at the 5-m site. Inorganic P (Resin-Pi, NaHCO3-Pi, and 1 M HCl-Pi) was positively correlated with the abundances of Flavobacterium, Pseudomonas, and Arthrobacter but negatively correlated with the abundance of Burkholderia; this highlights the different functional bacteria involved in P cycling. Conclusions: We conclude that BCF generally increases soil P availability and supply, and the changes in the P forms were closely related to the changes in soil bacterial community composition. However, excessive grazing density or long-term BCF practices can cause soil nutrient imbalance, labile and moderately labile P accumulation, and P leaching. Therefore, appropriate grazing densities and/or an interval of no grazing are required under the BCF model for effective and sustainable bamboo forest management.

“…A fresh bud sample weighing around 0.1 g was used to measure the N concentration, by using the Vario MACRO Cube Analyzer (Elementar, Germany), following the protocol of Tian et al [32]. Moreover, the concentrations of P, K, Ca, Mg, S, Fe, Mn, B, Cu and Zn were determined by taking a 0.3 g dried bud sample.…”

Wizened buds are frequently observed in pear (Pyrus spp.) trees, which greatly reduces the yield. However, little is known about the mechanism of wizened bud formation. Here, we analyzed physiological and transcriptomic differences between normal buds and wizened buds of ‘710’ pear trees. The results indicated that the sorbitol and boron (B) contents, during bud differentiation, were significantly reduced in wizened buds. The microscopic observation and transcriptome analysis revealed that the collapse of the organ structure and cell wall loosening process may have a close relation with wizened bud formation. Moreover, reduced transcript levels of PpyMYB39.1 and its downstream genes (PpyHT1, PpyHT2, PpyPMEI1 and PpyPMEI2) were found in wizened buds. However, the transcript levels of pentose and glucuronate interconversion pathway genes (PpyPME3, PpyPL18.1, PpyPL18.2, PpyPG1 and PpyPG2) and the concentration of pectin-degradation-related enzymes were increased in wizened buds. Correspondingly, the pectin concentration was significantly reduced in wizened buds. Taken together, PpyMYB39.1 may promote pectin degradation and decrease carbohydrate transport by regulating its downstream genes and is supposed to play a vital role in the wizened bud formation resulting from the cell wall loosening process. Our study provides fundamental insights into wizened bud formation and strategies to reduce the wizened bud occurrence in pear trees.
