Due to the long durations spent inside by many humans, indoor air quality has become a growing concern. Biofiltration has emerged as a potential mechanism to clean indoor air of harmful volatile organic compounds (VOCs), which are typically found at concentrations higher indoors than outdoors. Root-associated microbes are thought to drive the functioning of plant-based biofilters, or biowalls, ...

Roots are the plant parts which facilitate the primary contact between a plant and pollutant and culturing of genetically transformed hairy roots of hyperaccumulator plant sp.Brassica juncea L. grown in vitro was established to study the potential of in vitro hairy root cultures for the uptake and accumulation of heavy metals (Ni and Zn) for their growth and biomass from an aquatic environment....

The role played by lateral roots and root hairs in promoting plant anchorage, and specifically resistance to vertical uprooting forces has been determined experimentally. Two species were studied, Allium cepa (onion) which has a particularly simple root system and two mutants of Arabidopsis thaliana, one without root hairs (rhd 2-1) and another with reduced lateral root branching (axr 4-2). Max...

Swertia species are widespread in Eastern and Southern Asian countries and used in traditional medicine as anti-pyretic, analgesic, gastro and liver tonic. Among different species, only Swertia longifolia grows in Iran. In this investigation, antioxidant, cytotoxic and acetylcholinesterase inhibitory activities of S. longifolia have been studied. Aerial parts and roots of the plant were collect...

In order to evaluate the impact of physical and chemical properties of soil on Bekras kind wheat yield in the city of Arak, a completely randomized block experimental plan has been implemented with three replications in the1390 crop year. Treatments include the overall condition and qualifications of wheat field 's soil in 18 wheat farms, which were randomly selected. Traits in this experiment ...

Arbuscular mycorrhizal (AM) fungi colonize roots improving plant water status and tolerance to drought. However, it is not clear whether the presence of AM would affect the photosynthesis and antioxidant gene-enzymes response, which help to alleviate drought stress of the host plant. Here, pot experiments were performed to investigate the effects of Rhizophagus irregularis, an AM fungus, on the...

Plant-mycorrhizal fungal interactions are ubiquitous in forest ecosystems. While ectomycorrhizal plants and their fungi generally dominate temperate forests, arbuscular mycorrhizal symbiosis is common in the tropics. In subtropical regions, however, ectomycorrhizal and arbuscular mycorrhizal plants co-occur at comparable abundances in single forests, presumably generating complex community stru...

In resource-poor environments, adjustment in plant biomass allocation implies a complex interplay between environmental signals and plant development rather than a delay in plant development alone. To understand how environmental factors influence biomass allocation or the developing phenotype, it is necessary to distinguish the biomass allocations resulting from environmental gradients or onto...

phytoremediation is a biological method by which plants are used to remove environmental pollution caused by toxic elements such as the accumulation of cadmium, copper, lead, chromium, etc. from soil. the arbuscular mycorrhizal fungi (amf) help the plant to increase uptake and translocation of low mobility nutrients and also micronutrients. in this research, arbuscular mycorrhizal inoculant was...
