Cross-infection by multiple soil-borne pathogens alters the physicochemical properties and microbial community structure of tobacco rhizosphere soil

Yanan Ruan, Chi Wang, Xiaodong Shao, Zuoxin Tang et autres

Soil-borne diseases of tobacco roots and stems, caused by pathogens including Ralstonia solanacearum (bacterial wilt), Phytophthora parasitica var. nicotianae (black shank), and root-knot nematodes (Meloidogyne spp.), represent critical threats to tobacco cultivation. However, information regarding alterations in rhizosphere soil properties and microbial …

Partitioning soil carbon emissions in a temperate oak forest: insights from metabolic theory and the role of fine roots and microbial biomass

Yuxue Zhang, Xiaowei Guo, Zuoxin Tang, Haiyang Zhang et autres

Abstract Assessment of soil organic carbon (SOC) dynamics is often inadequately represented in empirical measurements because of the significant heterogeneity in soil structure and physico-chemical properties. Partitioning soil carbon (C) emissions into autotrophic and heterotrophic respiration is essential for understanding CO 2 …

Morphological Plasticity of Ectomycorrhizal Symbiosis Promotes Adaptation of Faxon Fir (Abies fargesii var. faxoniana) to Altitudinal and Environmental Changes on Eastern Qinghai–Tibet Plateau

Lulu Chen, Xuhua Li, Zuoxin Tang, Gexi Xu

Morphological plasticity (MP) is an essential strategy for plants in nutrient acquisition, disturbance alleviation, and community coexistence during environmental and climatic changes. However, to date, there has been little research concerning the MP for alpine–subalpine forests on the Qinghai–Tibet plateau. These forests …
