Description:
Zn tissue accumulation in Solanum nigrum grown in a non-contaminated and a naturally contaminated Zn matrix and the effect of inoculation with different arbuscular mycorrhizal fungi (AMF) on metal uptake were assessed. S. nigrum grown in the contaminated soil always presented higher Zn accumulation in the tissues, accumulating up to 1622mg Zn kg^-^1. The presence of both Glomus claroideum and Glomus intraradices enhanced the uptake and accumulation of Zn by S. nigrum (up to 83 and 49% higher Zn accumulation, respectively). The main deposits of the metal were found in the intercellular spaces and in the cell walls of the root tissues, as revealed by autometallography, with the inoculation with different AMF species causing no differences in the location of Zn accumulation. These findings indicate that S. nigrum inoculated with selected heavy metal tolerant AMF presents extracting and accumulating capacities, constituting a potentially suitable remediation method for Zn polluted soils.

Description:
Colonization by and diversity of arbuscular mycorrhizal (AM) fungi associated with five common ephemerals, Eremopyrum orientale (L.) Jaub. et Spach., Gagea sacculifera Regel., Plantago minuta Pall., Tragopogon kasahstanicus S. Nikit., and Trigonella arcuata C. A. Mey. were investigated in four typical desert plant communities in Junggar Basin, northwest China. All five ephemerals examined were found to be colonized and formed typical arbuscules or vesicles. The proportion of root length colonized ranged from 2 to 85% with an average of 19%. Spore density in soil near the roots of different ephemerals varied from 1 to 120 spores per 20ml soil, with an average value of 33 spores. Species richness averaged 8.8 AM fungal species in soil near the roots and ranged from 2 to 21. Fifty-four AM fungal taxa belonging to the genera Acaulospora, Archaeospora, Entrophospora, Glomus and Paraglomus were isolated and identified from soil around the roots. Glomus was the dominant AM fungal genus with a frequency of 100% and relative abundance of 82.6%. The AM fungal species with the highest frequency of occurrence was Glomus aggregatum with a frequency of 75%. G. microaggregatum was present in the highest relative abundance (16%). G. sacculifera, P. minuta and T. arcuata formed Arum-type mycorrhizas. Arbuscular mycorrhizal fungi are ubiquitous and Arum-type mycorrhizas are especially prevalent in these important desert communities used for grazing and traditional medicine.

Effects of arbuscular mycorrhizal fungi on the root uptake and translocation of radiocaesium [An article from: Environmental Pollution]
Effects of arbuscular mycorrhizal fungi on the root uptake and translocation of radiocaesium [An article from: Environmental Pollution]

Description:
Because mycorrhizal fungi are intimately associated with plant roots, their importance in radionuclide (RN) recycling and subsequent dispersion into the biosphere has received an increasing interest. Recently, the capacity of arbuscular mycorrhizal fungi to take up and translocate radiocaesium to their host was demonstrated. However, the relative contribution of these processes in comparison to the ones of roots remains unknown. Here, the respective contributions of the hyphae of a Glomus species and the transformed carrot (Daucus carota L.) roots on radiocaesium uptake and translocation were compared and quantified. We observed that radiocaesium uptake by hyphae was significantly lower as compared to that of the roots, while the opposite was noted for radiocaesium translocation/uptake ratio. We also observed that the intraradical fungal structures might induce a local accumulation of radiocaesium and concurrently reduce its translocation within mycorrhizal roots. We believe that intraradical fungal structures might induce the down-regulation of radiocaesium channels involved in the transport processes of radiocaesium towards the xylem.

9GrenBox – Adenium Desert ROSE Black Fire House Plant Bonsai
9GrenBox – Adenium Desert ROSE Black Fire House Plant Bonsai
- Desert Rose is one of our ultra favorite plants. Native to arid areas of Africa including Madagascar, Tanzania, Kenya and Uganda, it is related to the Plumeria
- This plant deserves FAR more appreciation. Desert Rose is excellent in pots especially for people who “kill everything” as the Adenium obesum lives with little care and can take a good deal of neglect.
- The coolest hybrids are produced in China, Taiwan and Thailand, and maybe India. Enjoy our personal desert rose collection.
- The plant will produces LARGE 7.0 cm flowers.
plant 5-7 inches tall that is
well-rooted in a 4 inch pot similar to the one in the second photo.
will ship without soil and pot. The diameter of this plant caudexes is about 4-6cm (sometimes it has multiple branches) .and should be planted soon upon arrival .

Species of arbuscular mycorrhizal fungi affect mycorrhizal responses to simulated herbivory [An article from: Applied Soil Ecology]
Species of arbuscular mycorrhizal fungi affect mycorrhizal responses to simulated herbivory [An article from: Applied Soil Ecology]

Description:
Herbivory is thought to influence the mycorrhizal associations between plants and their fungal symbionts by limiting the amount of photosynthate available to the fungus. So far, studies of the herbivory-mycorrhiza relationship have not yielded consistent results. This may be related to differences between species of fungi, or the frequency of the herbivory. This study tested the effects of arbuscular mycorrhizal fungal (AMF) species with varying clipping frequency on the phenology and colonization by AMF in the roots of Bromus inermis. The species of AMF significantly affected root and shoot biomass, as well as the degree of mycorrhizal colonization. Clipping frequency also influenced plant biomass and mycorrhizal phenology. High frequency clipping typically had the strongest effect on the variables measured. However, the extent of the clipping effect was dependent on which AMF species were associated with the plant, and which mycorrhizal structure was assessed. For example, intraradical hyphae and arbuscules were negatively affected by clipping, whereas the production of vesicles and spores was stimulated, albeit to different degrees in different AMF species. In contrast, extraradical hyphal length did not respond significantly to clipping. This AMF x clipping interaction indicates that it is difficult to generalize on the effects of herbivory on plant and fungal responses, even when dealing with the same plant species.
