Design, synthesis and nematocidal activity of novel 1,2,4-oxadiazole derivatives with a 1,3,4-thiadiazole amide moiety

Dan Liu, Zhengxing Wang, Jing-Jiang Zhou & Xiuhai Gan
A series of novel 1,2,4-oxadiazole derivatives containing 1,3,4-thiadiazole amide group was synthesized and their nematocidal activities were evaluated. The results indicated that compounds 4-methoxy-N-(5-(((3-(p-tolyl)-1,2,4-oxadiazol-5-yl)methyl)thio)-1,3,4-thiadiazol-2-yl)benzamide 4i and N-(5-(((3-(4-chlorophenyl)-1,2,4-oxadiazol-5-yl)methyl)thio)-1,3,4-thiadiazol-2-yl)benzamilde 4p showed good nematocidal activity against Bursaphelenchus xylophilus. The corrected mortality of compounds 4i and 4p at 200 mg/L was 57.1% and 60.1%, respectively, which are much better than 13.5% of the commercial seed coating agent Tioxazafen. Compounds 4i and 4p dramatically decreased the head swinging, body fluctuation,...

Increased interannual precipitation variability enhances the carbon sink in a semiarid grassland

Jingyi Ru, Shiqiang Wan, Dafeng Hui, Jian Song & Jing Wang
1. The amplifying interannual precipitation variability has been observed globally and is projected to intensify under climate change scenarios. However, its impacts on terrestrial vegetation and carbon (C) sink have not been well investigated. 2. As part of a field manipulative experiment with three precipitation variabilities (20%, 40%, and 60%) in a semiarid grassland, this study was conducted to examine the responses of ecosystem C cycling to increased precipitation variability. 3. Across the 3 experimental...

Data for: Plasticity and co-variation of root traits govern phosphorus acquisition among 20 wheat genotypes

Hongbo Li, Xin-Xin Wang, Jiaqi Zhang, Hong Wang & Zed Rengel
Trait plasticity (variation of a trait under environmental variability or gradients) and trait integration are both crucial for plant adaption to environmental change. Variations in different suite of root traits such as biomass allocation, morphology and physiology underlie diverse phosphorus (P) acquisition strategies among plants. Yet, how the intraspecific plasticity and integration of root traits influence plant adaptation to different P supply remains obscure. To characterize diverse adaptive strategies in relation to plant P acquisition,...

Data from: Nitrogen enrichment alters multiple dimensions of grassland functional stability via changing compositional stability

Qianna Xu, Xian Yang, Jian Song, Jingyi Ru, Jianyang Xia, Shaopeng Wang, Shiqiang Wan & Lin Jiang
Anthropogenic nutrient enrichment is known to alter the composition and functioning of plant communities. However, how nutrient enrichment influences multiple dimensions of community- and ecosystem-level stability remains poorly understood. Using data from a nitrogen (N) and phosphorus (P) addition experiment in a temperate semi-arid grassland that experienced a natural drought, we show that N enrichment, not P enrichment, decreased grassland functional and compositional temporal stability, resistance, and recovery, but increased functional and compositional resilience. Compositional...

Intra-annual species gain overrides species loss in determining species richness in a typical steppe ecosystem after a decade of nitrogen enrichment

Ming Zhao, Hongxiang Zhang, Baskin Carol, Cunzheng Wei, Junjie Yang, Yunhai Zhang, Yong Jiang, Lin Jiang & Xingguo Han
Increasing deposition of atmospheric nitrogen (N) due to accelerated human activities is a threat to various ecosystems. However, there is a lack of long-term experimental evidence demonstrating the seasonal dynamics of plant species turnover that ultimately determine species richness in natural ecosystems under N enrichment. Moreover, the frequency of N addition also may affect species turnover in a community, but it is rarely studied. To assess the responses of a plant community to N addition,...

Defective autophagy contributes to endometrial epithelial-mesenchymal transition in intrauterine adhesions

Zhenhua Zhou, Huiyan Wang, Xiwen Zhang, Minmin Song, Simin Yao, Peipei Jiang, Dan Liu, Zhiyin Wang, Haining Lv, Ruotian Li, Ying Hong, Jianwu Dai, Yali Hu & Guangfeng Zhao
Intrauterine adhesions (IUA), characterized by endometrial fibrosis, is a common cause of uterine infertility. We previously demonstrated that partial epithelial-mesenchymal transition (EMT) and the loss of epithelial homeostasis play a vital role in the development of endometrial fibrosis. As a pro-survival strategy in maintaining cell and tissue homeostasis, macroautophagy/autophagy, conversely, may participate in this process. However, the role of autophagy in endometrial fibrosis remains unknown. Here, we demonstrated that autophagy is defective in endometria of...

Visualizing biogeochemical heterogeneity in soils and sediments: A review of advanced micro-scale sampling and imaging methods

Cai Li, Shiming Ding, Musong Chen, Zhilin Zhong, Qin Sun & Yan Wang
For soils and sediments, which are complex and heterogeneous, root-triggered processes, bioturbation of benthic communities, and local decomposition of reactive organic materials can greatly increase their biogeochemical heterogeneity. In practice, common monitoring methods can only be used to determine the centimeter- to millimeter-scale heterogeneity from vertical or horizontal one-dimensional profiles. However, significant heterogeneity exists in both soils and sediments on the millimeter to sub-millimeter scales. Therefore, in-situ and high-resolution sampling and imaging methods are essential...

Increased precipitation and nitrogen addition accelerate the temporal increase of soil respiration during eight-year old-field grassland succession

Jiajia Zhang, Jingyi Ru, Jian Song, Heng Li, Xiaoming Li, Yafei Ma, Zheng Li, Yuanfang Hao, Zhensheng Chi, Dafeng Hui & Shiqiang Wan
Ecological succession after disturbance plays a vital role in influencing ecosystem structure and functioning. However, how global change factors regulate ecosystem carbon (C) cycling in successional plant communities remains largely elusive. As part of an eight-year (2012-2019) manipulative experiment, this study was designed to examine the responses of soil respiration and its heterotrophic component to simulated increases in precipitation and atmospheric nitrogen (N) deposition in an old-field grassland undergoing secondary succession. Over the eight-year experimental...
