“…A recent paper (Meding and Zasoski 2008) has provided data which appears at odds with the findings of Chen et al (2007) and Christophersen et al (in press). They tested the ability of As (as Na 2 AsO 4 ) supplied (supposedly as a tracer for Pi) to the cut foliage of donor plants to move down to the roots, through AM hyphae to receiver plants.…”

Arsenic uptake and toxicity in plants: integrating mycorrhizal influences

et al. 2009

Arsenic (As) contamination of soil and water is a global problem that impacts on many areas of biology. This review firstly covers aspects of soil chemistry and soil-plant interactions relevant to the ways plants take up As (particularly arsenate (As(V)) from aerobic soils, with especial attention to As-phosphorus (P) interactions. It then assesses the extent to which studies of plant As tolerance based on short-term uptake of As(V) from nutrient solutions can be extrapolated to longer-term growth in contaminated soil. Mycorrhizal symbioses are then highlighted, because they are formed by~90% of higher plants, often with increased uptake of phosphate (Pi) compared with non-mycorrhizal (NM) counterparts. It is therefore likely that mycorrhizas influence As(V) uptake. Published work shows that arbuscular mycorrhizal (AM) plants (the most common mycorrhizal type) have higher P/As ratios than NM plants, and this would be expected to affect sensitivity to soil As. We discuss ways in which higher P/As selectivity might result from differential operation of P and As uptake pathways in AM compared with NM plants, taking into account new understanding of P uptake mechanisms. We also give suggestions for future research required to increase understanding of mechanisms of As(V) uptake, and its interactions with plant P.

“…AMF can provide direct benefits to invasive plants by increasing nutrient and water uptake (Smith and Read, 1997) and can also provide indirect benefits to plants by altering competitive hierarchies with native species, or even directly transferring resources or carbon between plants (Chiariello et al, 1982;Meding and Zasoski, 2008). However, the generality of these benefits, even for a given plant species, is unknown.…”

“…Arbuscular mycorrhiza inoculation improves water usage under irrigated and non-irrigated systems and enhances soil mineral uptake, especially P (Sari et al, 2002;Kaya et al, 2003;Meding and Zasoski, 2008). In previous studies, AM fungi Glomus mosseae had a positive effect on different plant species (Chandanie et al, 2006;Smith and Read, 2008).…”

Worldwide, a significant increase in watermelon (Citrullus lanatus [Thunb.] Matsum. & Nakai) growing areas has been registered in the last few years. In-row plant spacing has a significant effect on the growth and yield of watermelon, and can enhance competition for water and nutrients. The aim of this study was to investigate the effects of in-row plant spacing however, the fruit weight was not affected by mycorrhizal inoculation during early or total harvest. In this study, an in-row plant spacing of 1.0 m provided the best early and total yield while maintaining high fruit weight. The growth and yield enhancement of watermelon due to mycorrhizal colonization was not consistent; therefore, mycorrhizal inoculation could not be recommended as a standard production practice.
