“…Considering the effects of P. indica on nutrient, in particular P uptake into the hosts and the growth responses published for various plant species, it is difficult to predict a putative correlation. The endophyte did not promote P uptake into Cyclamen under low P conditions, but increased the P content of the plant under normal P supply [33]. On the other hand, the endophyte increased the biomass and yield in tobacco but did not promote P accumulation [34].…”

BackgroundAnthurium andraeanum, an important ornamental flower, has to go through a growth-delaying period after transfer from tissue culture to soil, which requires time and extra costs. Furthermore, during this period, the plantlets are highly susceptible to bacterial infections, which results in impaired development and severe losses. Here, we aimed to address whether application of the endophytic fungus, Piriformospora indica protects the A. andraeanum root system during the critical propagation period, and whether P. indica reduce the mortality rate by stimulating the host’s resistance against diseases.ResultsWe demonstrate that P. indica shortens the recovery period of Anthurium, promotes growth and confers disease resistance. The beneficial effect of P. indica results in faster elongation of Anthurium roots early in the interaction. P. indica-colonized plants absorb more phosphorus and exhibit higher photosynthesis rates than uncolonized control plants. Moreover, higher activities of stress-related enzymes, of jasmonic acid levels and mRNA levels of jasmonic acid-responsive genes suggest that the fungus prepares the plant to respond more efficiently to potentially upcoming threats, including bacterial wilt.ConclusionThese results suggest that P. indica is a helpful symbiont for promoting Anthurium rooting and development. All our evidences are sufficient to support the disease resistance conferred by P. indica through the plant-fungal symbiosis. Furthermore, it implicates that P. indica has strong potential as bio-fertilizer for utilization in ornamental plant cultivation.

“…Phosphorus (P) uptake was analyzed according to a modified method after Goehler and Drews (1978) , Ehrenberger (1991) , and Ghanem et al (2014) . Dried and pulverized randomly selected samples of shoot tissues (250 mg per sample) were subjected to an acid digestion (adding 2 mL of 65% HNO 3 directly to the sample with 2 mL of 30% hydrogen peroxide and 5 mL H 2 O placed outside the sample vessel) at 200°C for 15 min in a microwave (μPREP-A microwave system, MLS GmbH, Leutkirch, Germany).…”

Beneficial Root Endophytic Fungi Increase Growth and Quality Parameters of Sweet Basil in Heavy Metal Contaminated Soil

How interactions between plants, the rhizosphere, and contaminated soil affect environmental sustainability is still under research. We tested the effects of two root endophytic fungi, the arbuscular mycorrhiza fungus (AMF) Rhizophagus irregularis and the beneficial endophyte Serendipita indica, on sweet basil (Ocimum basilicum) growing on soil contaminated with lead and copper in a pot experiment under defined greenhouse conditions. Both fungi caused an increase in shoot and root dry weight of sweet basil plants under all conditions and decreased the amount of lead in shoots. The amount of copper was reduced by S. indica, while the AM fungus showed this effect only when the soil is contaminated with both copper and lead. Furthermore the AMF, but not the endophyte S. indica caused a strong increase on the concentrations of the essential oils linalool and eucalyptol even on sweet basil growing on contaminated soils. Hence, cultivating sweet basil in combination with beneficial fungi in case of difficult environmental conditions could be of interest for industry located in countries with widespread land pollution, because quantity and quality of plants are increased while the amount of heavy metals is generally reduced.

“…Infested plants have been observed to produce higher yields and display increased tolerance of biotic and abiotic stresses when compared to controls (Waller et al 2005 ). Increases in plant growth may be attributable to an increased ability to acquire nutrients, in particular phosphorous, in the presence of P. indica (Yadav et al 2010 ; Ghanem et al 2014 ). Interestingly, studies involving co-inoculation of Cicer arietinum (chickpea) with P. indica and the PGPR Pseudomonas striata found the presence of P. indica resulted in short term increases in P. striata in the rhizosphere (Meena et al 2010 ).…”

Plant root-microbe communication in shaping root microbiomes

A growing body of research is highlighting the impacts root-associated microbial communities can have on plant health and development. These impacts can include changes in yield quantity and quality, timing of key developmental stages and tolerance of biotic and abiotic stresses. With such a range of effects it is clear that understanding the factors that contribute to a plant-beneficial root microbiome may prove advantageous. Increasing demands for food by a growing human population increases the importance and urgency of understanding how microbiomes may be exploited to increase crop yields and reduce losses caused by disease. In addition, climate change effects may require novel approaches to overcoming abiotic stresses such as drought and salinity as well as new emerging diseases. This review discusses current knowledge on the formation and maintenance of root-associated microbial communities and plant–microbe interactions with a particular emphasis on the effect of microbe–microbe interactions on the shape of microbial communities at the root surface. Further, we discuss the potential for root microbiome modification to benefit agriculture and food production.
