Role of root colonization ability of plant growth promoting fungi in the suppression of take-all and common root rot of wheat

The Plant Growth-promoting Fungus Penicillium spp. GP15-1 Enhances Growth and Confers Protection against Damping-off and Anthracnose in the Cucumber

“…However, the ability of PGPF to degrade barley grains and release nutrients, thus additively stimulating plant growth, cannot be ruled out. Shivanna et al 20 showed that the ammonium-N content of barley grains colonized by certain PGPF isolates was increased due to colonization by these isolates, and consequently the ammonium-N could be more readily utilized by roots, leading to an enhancement of plant growth. In our study, the greatest growth promotion effects of GP15-1 were observed when its inoculum was applied at a 0.5 rate, rather than a 1.0 rate.…”

“…The other mechanisms of disease suppression by PGPF are likely to include competition with pathogens for infection sites on the root surface. Shivanna et al 20 showed that PGPF reduced the colonization ability of pathogens on roots, suggesting that mechanisms other than competition for infection sites may be involved. Therefore, another possible mechanism of disease suppression could be induced resistance in cucumber plants, elicited by GP15-1.…”

“…rhizospheres harbored certain PGPF, which were capable of increasing dry matter production of a variety of crop plants by several folds 2,13 . In some cases, significant growth-promoting effects of these PGPF were observed, in terms of increased plant yield over periods of 14 weeks or more 20 .…”

“…These zoysiagrass rhizosphere PGPF isolates also acted as BCAs when tested against the soilborne diseases of several crop plants 20 . Moreover, certain isolates were good inducers of systemic resistance against a wide range of diseases when provided as barley grain inocula, mycelia, or as cellfree filtrates 2, 12 14 .…”

Improvement of Soil Properties, Growth of Cucumber and Protection against Fusarium Wilt by Piriformospora indica and Two Industrial Organic Wastes

“…Previous studies have shown the potential of certain bacteria and fungi to control FW, increase uptake of minerals and promote plant growth (Kennedy and Smith, 1995;Doran et al, 1996;Shivanna et al, 1996;Moharam and Negim, 2012). One of the candidate fungi recently tested for these purposes is P. indica, a plant-root-colonizing fungus belonging to the Basidiomycotina.…”
