Schizolobium parahyba var. amazonicum (Huber ex Ducke) occurs naturally in the Brazilian Amazon. Currently, it is being planted extensively because of its fast growth and excellent use in forestry. Consequently, there is great interest in new strategies to increase wood production. The interaction between soil microorganisms and plants, specifically in the roots, provides essential nutrients fo...

abstract plants are exposed to stressful environmental conditions in the process of growth and development. one of the most important stresses is the salt stress which can limit the plant’s growth and yield. plants symbiosis with arbuscular mycorrhizal fungi in salt conditions can affect the plant’s yield as well as growth parameters. the plant’s growth in salt stressful conditions might be red...

†Background Myco-heterotrophic plants are partly or entirely non-photosynthetic plants that obtain energy and nutrients from fungi. These plants form a symbiosis with arbuscular mycorrhizal, ectomycorrhizal or saprotrophic fungi to meet their nutrient demands. † Scope This Botanical Briefing summarizes current knowledge about myco-heterotrophy, discusses its controversial aspects and highlights...

Arbuscular mycorrhizal fungi (AMF), a special microorganism can connect soil and a plant directly, plays an important role in environmental remediation [1]. When the plant is in the heavy metal adversity, mycorrhizal association can enhance the resistance to the metals of plants [2]. Chen et al. [3], reported Cu uptake by four kind of mycorrhizal plants including two native plant species, Coreo...

grafting and mycorrhizal fungi have gained interest for the positive effects they can have on vegetable crops. the aim of this work was to study the combined effect of grafting with vesicular-arbuscular mycorrhizal fungi (amf) inoculation on fruit yield and quality of mini-watermelon [citrullus lanatus (thumb.) matsum and nakai]. ungrafted plants or grafted onto rootstock rs 841 (cucurbita maxi...

The tolerance of lettuce plants (Lactuca sativa L. cv. Romana) to drought stress differed with the arbuscular-mycorrhizal fungal isolate with which the plants were associated. Seven fungal species belonging to the genus Glomus were studied for their ability to enhance the drought tolerance of lettuce plants. These fungi had different traits that affected the drought resistance of host plants. T...

The response of plants to arbuscular mycorrhizal fungi involves a temporal and spatial activation of different defence mechanisms. The activation and regulation of these defences have been proposed to play a role in the maintenance of the mutualistic status of the association, however, how these defences affect the functioning and development of arbuscular mycorrhiza remains unclear. A number o...

Salinity adversely affects crops metabolism and yield. The present work was conducted to evaluate the singular and interaction influences of Arbuscular mycorrhizal (AM) fungi and brassinolide, as an active group of (brassinosteroids) BRs, on some physiological parameters of wheat plants to cope with salt stress14-day old mycorrhizal (Glomus mosseae) and non- mycorrhizal wheat (Triticum aestivum...
