Mycorrhizal communities of two closely related species, Pyrola subaphylla and P. japonica , with contrasting degrees of mycoheterotrophy in a sympatric habitat Mycorrhiza (IF 3.069) Pub Date : 2020-11-20 Kenji Suetsugu, Shunsuke Matsuoka, Kohtaroh Shutoh, Hidehito Okada, Shintaro Taketomi, Kaede Onimaru, Akifumi S. Tanabe, Hiroki Yamanaka
Mycoheterotrophic plants typically form associations with a narrow range of mycorrhizal fungi. Consequently, mycorrhizal specialization is often considered to be an important step in mycoheterotrophic evolution. However, it remains unclear whether such specialization is likely to occur in plants of the genus Pyrola, which are generally associated with fungi in multiple ectomycorrhizal families. Here

Morpho-anatomical differences among mycoheterotrophic Afrothismia spp. (Thismiaceae) indicate an evolutionary progression towards improved mycorrhizal benefit. Mycorrhiza (IF 3.069) Pub Date : 2020-05-08 Stephan Imhof,Benjamin Feller,Anna Heser
Achlorophyllous, mycoheterotrophic plants depend on their mycorrhizal fungi for 100% of their carbon supply. Hence, there is strong evolutionary pressure towards a well-organized functioning of the association from the plant’s perspective. Members of the mycoheterotrophic genus Afrothismia have evolved elaborate fungal colonization patterns allowing a sustained benefit from external fungal penetration

Effects of single and multiple species inocula of arbuscular mycorrhizal fungi on the salinity tolerance of a Bangladeshi rice (Oryza sativa L.) cultivar. Mycorrhiza (IF 3.069) Pub Date : 2020-05-04 Shanaz Parvin,Maarten Van Geel,Tanzima Yeasmin,Erik Verbruggen,Olivier Honnay
Soil salinization due to sea level rise and groundwater irrigation has become an important agronomic problem in many parts of the world. Symbiosis between crop species and arbuscular mycorrhizal fungi (AMF) may alleviate salt stress-induced detrimental effects on crop growth and yield, for example, through helping the host plant to selectively absorb potassium while avoiding uptake of excessive sodium

Rapid nitrogen loss from ectomycorrhizal pine germinants signaled by their fungal symbiont. Mycorrhiza (IF 3.069) Pub Date : 2020-05-03 Joshua M Smith,Matthew D Whiteside,Melanie D Jones
Ectomycorrhizal fungi supply their plant partners with nitrogen but can also retain substantial amounts. The concentration of nitrogen in the soil and the amount of carbon supplied from the host seem to influence the proportion of N retained by the fungus. In an experiment designed to determine whether differential supply of nitrogen to two plants influenced nitrogen transfer from fungus to plant within

Ericoid mycorrhizal fungi enhance salt tolerance in ericaceous plants. Mycorrhiza (IF 3.069) Pub Date : 2020-05-03 Sepideh Fadaei,Maryamsadat Vaziriyeganeh,Michelle Young,Ira Sherr,Janusz J Zwiazek
To examine the effects of ericoid mycorrhizal (ERM) fungi on salt tolerance of ericaceous plants, we inoculated roots of velvetleaf blueberry (Vaccinium myrtilloides), Labrador tea (Rhododendron groenlandicum), and lingonberry (Vaccinium vitis-idaea) with ericoid mycorrhizal fungi Oidiodendron maius and Meliniomyces variabilis. Plants were subjected to 0 (NaCl control) and 30 mM NaCl treatments, and

HyLength: a semi-automated digital image analysis tool for measuring the length of roots and fungal hyphae of dense mycelia. Mycorrhiza (IF 3.069) Pub Date : 2020-04-16 Alessio Cardini,Elisa Pellegrino,Emanuela Del Dottore,Hannes A Gamper,Barbara Mazzolai,Laura Ercoli
In plant-fungus phenotyping, determining fungal hyphal and plant root lengths by digital image analysis can reduce labour and increase data reproducibility. However, the degree of software sophistication is often prohibitive and manual measuring is still used, despite being very time-consuming. We developed the HyLength tool for measuring the lengths of hyphae and roots in in vivo and in vitro systems

Combined effects of phosphorus and magnesium on mycorrhizal symbiosis through altering metabolism and transport of photosynthates in soybean. Mycorrhiza (IF 3.069) Pub Date : 2020-04-15 Jinzhuan Qin,Huicong Wang,Huayuan Cao,Kang Chen,Xiurong Wang
Arbuscular mycorrhizal (AM) symbiosis plays crucial roles in plant nutrient uptake. However, little is known about the combined effects of phosphorus (P) and magnesium (Mg) on mycorrhizal symbiosis. In the present study, a pot experiment was carried out using two soybean genotypes in the presence or absence of Rhizophagus irregularis inoculation under different P and Mg conditions. The results showed

Increased arbuscular mycorrhizal fungal colonization reduces yield loss of rice (Oryza sativa L.) under drought. Mycorrhiza (IF 3.069) Pub Date : 2020-04-15 Anupol Chareesri,Gerlinde B De Deyn,Lidiya Sergeeva,Anan Polthanee,Thomas W Kuyper
Drought reduces the availability of soil water and the mobility of nutrients, thereby limiting the growth and productivity of rice. Under drought, arbuscular mycorrhizal fungi (AMF) increase P uptake and sustain rice growth. However, we lack knowledge of how the AMF symbiosis contributes to drought tolerance of rice. In the greenhouse, we investigated mechanisms of AMF symbiosis that confer drought

Arbuscular mycorrhiza induced putrescine degradation into γ-aminobutyric acid, malic acid accumulation, and improvement of nitrogen assimilation in roots of water-stressed maize plants. Mycorrhiza (IF 3.069) Pub Date : 2020-04-06 Yanbo Hu,Baodong Chen
Water shortage limits plant growth and development by inducing physiological and metabolic disorders, while arbuscular mycorrhizal (AM) symbiosis can improve plant adaptation to drought stress by altering some metabolic and signaling pathways. In this study, root growth and levels of some metabolites (polyamines, amino acids, and malic acid [MA]) and key enzymes were examined in AM-inoculated and non-inoculated

Facilitation of plant water uptake by an arbuscular mycorrhizal fungus: a Gordian knot of roots and hyphae. Mycorrhiza (IF 3.069) Pub Date : 2020-04-06 David Püschel,Michael Bitterlich,Jana Rydlová,Jan Jansa
Arbuscular mycorrhizal (AM) fungi play a positive role in plant water relations, and the AM symbiosis is often cited as beneficial for overcoming drought stress of host plants. Nevertheless, water uptake via mycorrhizal hyphal networks has been little addressed experimentally, especially so through isotope tracing. In a greenhouse study conducted in two-compartment rhizoboxes, Medicago truncatula was
