What benefits of Glomus deserticola have been cited in the scientific literature?
For growers searching Glomus deserticola drought tolerance, the literature is notable. In a seven-species comparison, it ranked most effective in lettuce under progressive drought stress, with only a 9% shoot dry weight reduction, the highest mycorrhizal colonization rates, and the greatest stimulation of transpiration, stomatal conductance, and P and K uptake among species tested. Rosemary (Rosmarinus officinalis) studies additionally report improved root hydraulic conductivity, photosynthetic efficiency, and osmotic adjustment capacity under water stress.

2Potential claims from the literature
Reported to increase chromium (Cr) accumulation in roots of Prosopis juliflora-velutina grown in Cr(VI)-contaminated soil, with inoculated plants showing 21% and 30% more Cr in roots than uninoculated and EDTA-treated plants, respectively, at 80 mg Cr kg⁻¹
Reported to result in higher metal concentrations in the vascular system of inoculated Prosopis juliflora-velutina plants grown in chromium-contaminated soil, as shown by X-ray mapping
Reported to increase aerial and root biomass of Rosmarinus officinalis under water stress conditions compared to non-mycorrhizal plants
Reported to improve root hydraulic conductivity of water-stressed Rosmarinus officinalis plants
Reported to enhance osmotic adjustment capacity in water-stressed Rosmarinus officinalis, as indicated by a greater decrease in osmotic potential at full turgor in mycorrhizal plants compared to non-mycorrhizal plants
Reported to improve photosynthetic activity and stomatal conductance in Rosmarinus officinalis under water stress compared to non-mycorrhizal stressed plants
Reported to maintain higher photochemical efficiency of PSII (Fv/Fm) and chlorophyll content in Rosmarinus officinalis under water stress compared to non-mycorrhizal plants
Reported to have a beneficial effect on water status of Rosmarinus officinalis under water-stress conditions, with mycorrhizal water-stressed plants showing a lower decrease in leaf and stem water potential than non-mycorrhizal water-stressed plants
Reported to be the most effective among seven Glomus species tested in improving drought tolerance of lettuce (Lactuca sativa), associated with the lowest level of shoot dry weight reduction (9%) under progressive drought stress
Reported to exhibit the highest levels of mycorrhizal colonization and the greatest stimulation of physiological parameters (including transpiration, stomatal conductance, and P and K acquisition) among seven Glomus species tested in lettuce under drought stress
Reported to improve mineral uptake (N, P, K) in lettuce under drought stress conditions
Reported to enhance accumulation of stress-related metabolites (proline, soluble sugars, flavonoids, anthocyanins) and antioxidant enzyme activity in tomato (Solanum lycopersicum) under drought priming conditions
Reported to increase biomass and survival rate of tomato (Solanum lycopersicum) under drought priming conditions, with low malondialdehyde content observed
Reported to mitigate the reduction of K, P, and Ca uptake in sweet basil (Ocimum basilicum) due to salinity, and to improve K/Na and Ca/Na balance in mycorrhizal plants
Reported to enhance growth, photosynthetic efficiency, gas exchange, water use efficiency, and chlorophyll content of sweet basil (Ocimum basilicum) under salinity stress
Reported to enhance productivity of sweet basil (Ocimum basilicum) under salinity conditions
Reported to improve growth of Eucalyptus globulus when inoculated in combination with sewage sludge amendment, with significant increases in dry shoot weight
Reported to stimulate significant Eucalyptus globulus growth and increases in shoot tissue content of N, P, K, Ca, Mg, and Fe
Reported to induce a significant increase in fluorescein diacetate (FDA) activity in Eucalyptus globulus soil, indicating enhanced soil biological activity
