Expression of MAX2 under SCARECROW promoter enhances the strigolactone/MAX2 dependent response of Arabidopsis roots to low-phosphate conditions
MAX2/strigolactone signaling in the endodermis and/or quiescent center of the root is partially sufficient to exert changes in F-actin density and cellular trafficking in the root ep...

The role of pre-symbiotic auxin signaling in ectendomycorrhiza formation between the desert truffle Terfezia boudieri and Helianthemum sessiliflorum
The ectendomycorrhizal fungus Terfezia boudieri is known to secrete auxin. While some of the effects of fungal auxin on the plant root system have been described, a comprehensive understanding is still lacking. A...

Strigolactones Involvement in Root Development and Communications
Strigolactones are plant hormones regulating both root and shoot development. They also have a role in plant communication in the rhizosphere. In this chapter we will present the role of strigolactones as regu...

Strigolactones in Root Exudates as a Signal in Symbiotic and Parasitic Interactions
Plants produce numerous secondary metabolites, many of which have a role in their development. The presence of such compounds in the rhizosphere led other organisms in the course of evolution to recognize thes...

Mycorrhizal association between the desert truffle Terfezia boudieri and Helianthemum sessiliflorum alters plant physiology and fitness to arid conditions
The host plant Helianthemum sessiliflorum was inoculated with the mycorrhizal desert truffle Terfezia boudieri Chatin, and the subsequent effects of the ectomycorrhizal relationship on host physiology were determ...

The synthetic strigolactone GR24 influences the growth pattern of phytopathogenic fungi
Strigolactones that are released by plant roots to the rhizosphere are involved in both plant symbiosis with arbuscular mycorrhizal fungi and in plant infection by root parasitic plants. In this paper, we desc...

Strigolactones affect lateral root formation and root-hair elongation in Arabidopsis
Strigolactones (SLs) have been proposed as a new group of plant hormones, inhibiting shoot branching, and as signaling molecules for plant interactions. Here, we present evidence for effects of SLs on root dev...

Effect of AMF application on growth, productivity and susceptibility to Verticillium wilt of olives grown under desert conditions
The effect of arbuscular mycorrhizal fungi (AMF) on olive (Olea europaea) growth and development was followed for 4 years after transplanting in irrigated commercial orchards under arid conditions. Sites I and II...

Strigolactones’ Effect on Root Growth and Root-Hair Elongation May Be Mediated by Auxin-Efflux Carriers
Strigolactones are a new group of plant hormones that play a pivotal role in the regulation of aboveground plant architecture. However, the mechanisms governing their regulation of plant growth and development...

Characterization of a novel tomato mutant resistant to the weedy parasites Orobanche and Phelipanche spp.
Orobanche and Phelipanche, commonly known as broomrape, are dicotyledonous holoparasitic flowering plants that cause heavy economic losses in a wide variety of plant species. Breeding for Orobanche resistance is ...

Arbuscular Mycorrhizal Symbiosis Under Stress Conditions: Benefits and Costs
Mycorrhization is a highly prevalent association of plants with fungi. Most plant species harbor symbioses with arbuscular mycorrhizal fungi (AMF), which take place within the plant roots. Arbuscular mycorrhiz...

Suitability of mycorrhiza-defective mutant/wildtype plant pairs (Solanum lycopersicum L. cv Micro-Tom) to address questions in mycorrhizal soil ecology
Despite the importance of arbuscular mycorrhizal fungi (AMF) to ecosystem processes, few experimental tools are available to quantify AMF contributions to process rates. In this study we examine the efficacy o...

Tomato sugar transporter genes associated with mycorrhiza and phosphate
In arbuscular mycorrhizal (AM) symbiosis, there is a reciprocal nutrient exchange between symbiotic partners. AM fungi assist the plants with uptake of mineral nutrients from the soil, especially phosphate (Pi...

Expression of a plant expansin is involved in the establishment of root knot nematode parasitism in tomato
A group of plant proteins, expansins, have been identified as wall-loosening factors and as facilitators of cell expansion in vivo. The root knot nematode Meloidogyne javanica establishes a permanent feeding site...

Responsive modes of Medicago sativa proline dehydrogenase genes during salt stress and recovery dictate free proline accumulation
Free proline accumulation is an innate response of many plants to osmotic stress. To characterize transcriptional regulation of the key proline cycle enzymes in alfalfa (Medicago sativa), two proline dehydrogenas...
