Understanding water use characteristics of plants and their interrelations is essential for achieving sustainable vegetation restoration of desert steppe. This study focused on five dominant plant species inhabiting two habitats: sierozem (, , and ) and aeolian sandy soil (, , and ). We analyzed δH and δO isotopes in xylem, soil water, groundwater, and precipitation.

Objectives: To observe the effect of mild moxibustion on stem cell factor (SCF)/tyrosine kinase receptor (c-kit) signaling pathway and visceral hypersensitivity of diarrhea predominant irritable bowel syndrome (IBS-D) model rats with liver- stagnation and spleen deficiency syndrome, so as to explore its mechanisms underlying improvement of IBS-D.

Methods: A total of 24 male Wistar rats were randomly divided into normal, IBS-D model, medication and mild moxibustion groups, with 6 rats in each group. The IBS-D model was established by glacial acetic acid (4%) enema plus restraint stress stimulation once daily for 14 days.

Article Synopsis
  • The study explores how iron nanostructures, specifically nanoscale zerovalent iron (nZVI), can enhance plant growth, particularly when combined with arbuscular mycorrhizal fungi (AMF).
  • An optimal dosage of 1.0 g·kg of nZVI can boost maize growth significantly, while excessive amounts harm plant roots and disrupt nutrient uptake, unlike FeSO which has minimal effects.
  • The appropriate nZVI facilitates the formation of a supportive nano structure on AMF, improving root colonization, gas exchange, and overall plant health, indicating nZVI plays a crucial role over traditional iron salts.

It remains unclear how symbiotic microbes impact the growth of peanuts when they are exposed to the pollutants cadmium (Cd) and microplastics (MPs) simultaneously. This study aimed to investigate the effects of endophytic bacteria Bacillus velezens SC60 and arbuscular mycorrhizal fungus Rhizophagus irregularis on peanut growth and rhizosphere microbial communities in the presence of Cd at 40 (Cd40) or 80 (Cd80) mg kg combined without MP or the presence of low-density polyethylene (LDPE) and poly butyleneadipate-co-terephthalate (PBAT). This study assessed soil indicators, plant parameters, and Cd accumulation indicators.

Article Synopsis
  • The paper discusses the evolution of dryland wheat through both natural and artificial selection, highlighting how artificial selection has influenced domestication and improvement of wheat varieties.
  • It outlines various aspects of dryland wheat's adaptation to stress, including physiological and morphological changes, as well as shifts in population attributes due to artificial selection.
  • The findings emphasize that dryland wheat production is a complex population process, and suggest breeding strategies for enhancing resilience in the face of climate change, balancing artificial and natural selection effects.

Three novel strains, RITF741T, RITF1220 and RITF909, isolated from root nodules of Acacia melanoxylon in Guangdong Province of China, have been previously identified as members of the genus Mesorhizobium, displaying the same 16S rRNA gene RFLP pattern. Phylogenetic analysis of 16S rRNA gene sequences indicated that the three strains belong to the genus Mesorhizobium and had highest similarity (100.0 %) to Mesorhizobium plurifarium LMG 11892T.

Salinity is one of the major abiotic stresses that impacts plant growth and reduces the productivity of field crops. Compared to field plants, test tube plantlets offer a direct and fast approach to investigate the mechanism of salt tolerance. Here we examined the ultrastructural and physiological responses of potato (Solanum tuberosum L.

Arbuscular mycorrhiza (AM) is one of the most widely distributed and the most important mutualistic symbionts in terrestrial ecosystems, playing a significant role in enhancing plant resistance to stresses, remediating polluted environments, and maintaining ecosystem stabilization and sustainable productivity. The structural characteristics of AM are the main indicators determining the mycorrhizal formation in root system, and have close relations to the mycorrhizal functions. This paper summarized the structural characteristics of arbuscules, vesicles, mycelia and invasion points of AM, and analyzed the relationships between the Arum (A) type arbuscules, Paris (P) type arbuscules, vesicles, and external mycelia and their functions in improving plant nutrient acquisition and growth, enhancing plant resistance to drought, waterlogging, salinity, high temperature, diseases, heavy metals toxicity, and promoting toxic organic substances decomposition and polluted and degraded soil remediation.

The aim of this study is to assess the mycorrhizal status of Eucalyptus plantations in south China and to determine the need for inoculation. In four provinces in south China, 155 plantations were sampled for sporocarps of ectomycorrhizal (ECM) fungi, spores of arbuscular mycorrhizal (AM) fungi, and mycorrhizas over 2 years. This study revealed a low above-ground diversity of ECM fungi consisting of 15 taxa fruiting beneath Eucalyptus plantations.

Plantation forestry with exotic trees in south China needs compatible symbionts to improve the growth of seedlings in nurseries and to enhance establishment and growth in the field. Scleroderma, a potentially suitable symbiont for inoculation, is not being used in containerized nurseries in the region due to poor knowledge of its host range. The ability of 15 collections of Scleroderma, nine from Australia and six from Asia, to colonize and promote growth of four important exotic plantation trees (Eucalyptus globulus Labill.
