1. While both arbuscular mycorrhizal (AM) fungi and plant and insect genotype are well known to influence plant and herbivore growth and performance, information is lacking on how these factors jointly influence the relationship between plants and their natural herbivores. 2. The aim of the present study was to investigate how a natural community of arbuscular mycorrhizal fungi affects the grow...

1. In the conventional view of soil carbon (C) cycling, mycorrhizal fungi are primarily considered vectors for plant C input to soils. However, there is accumulating evidence that mycorrhizal fungi may also contribute to the direct loss of soil C by acting as decomposers, that is by producing extracellular lytic enzymes and metabolizing soil C. 2. Most of the evidence that mycorrhizal fungi can...

An estimated 90% of terrestrial plants form symbiotic associations with soil fungi, and the majority of those plant species belong to families that characteristically form associations with arbuscular mycorrhizal (AM) fungi (Smith & Read, 1997). The function of these associations is largely based upon the transfer of carbon (C) from the plant to the fungus, and upon the transfer of mineral nutr...

Over the last years the role of fungal endophytes in plant biology has been extensively studied. A number of species were shown to positively affect plant growth and fitness, thus attempts have been made to utilize these microorganisms in agriculture and phytoremediation. Plant-fungi symbiosis requires multiple metabolic adjustments of both of the interacting organisms. The mechanisms of these ...

Since the beginning of the 90s lots of cationic plant, cysteine-rich antimicrobial peptides (AMP) have been studied. However, Broekaert et al. (1995) only coined the term "plant defensin," after comparison of a new class of plant antifungal peptides with known insect defensins. From there, many plant defensins have been reported and studies on this class of peptides encompass its activity towar...

the effects of arbuscular mycorrhizal fungi on nitrogen concentration of berseem clover were examined in contaminated soil with cadmium. examined factors included: levels of arbuscular mycorrhizal fungi inoculation ( glomus mosseae ) (with and without inoculation), and different levels of soil contamination by cadmium (0, 5, 10, 20, 40 and 80 mg.kg-1). the results showed that the effects of cad...

In recent years, the use of soil microbial potential including arbuscular mycorrhizal fungi is widely considered to enhance the better growth and nutrition of plants. This research was conducted in order to study the impact of mycorrhizal fungi on the increase of yarrow production and the plant establishment affected by the symbiotic ...

Most classical plant hormones are also produced by pathogenic and symbiotic fungi. The way in which these molecules favour the invasion of plant tissues and the development of fungi inside plant tissues is still largely unknown. In this review, we examine the different roles of such hormone production by pathogenic fungi. Converging evidence suggests that these fungal-derived molecules have pot...

in the present study, the effect of two species of amf, glomus mosseae and glomus intraradices, alone and in combination, was evaluated on the growth criteria, chlorophyll content, and root rot disease caused by fusarium solani f. sp. pisi, on chickpea (cicer arietinum l.) under greenhouse conditions. chickpea seeds were sown into pots containing 100 g of amf inoculum (more than 1,000 propagule...

Volume 1 • Issue 5 • 1000e117 J Plant Biochem Physiol ISSN: 2329-9029 JPBP, an open access journal The versatility of fungi allows them to associate with plants in many ways. When interacting with a live organism, a fungus will invade its plant host and manipulate its metabolisms either detrimentally or beneficially, depending on whether the fungus is a pathogen or a symbiote. Many crop disease...
