“…Different mycorrhiza-like short roots were formed depending on the hormonal treatment. These findings were confirmed by Palmer (1954), but Barnes andNaylor (1959a, 1959b) and Ulrich (1960b) were unable to induce mycorrhiza-like short roots with hormonal treatments. Slankis (1948) induced root structures bearing a very close resemblance to mycorrhizae with culture filtrates of ectomycorrhizal fungi.…”

“…On the basis of these findings, Moser (1959Moser ( , 1962, Ulrich (1960a), Horak (1963Horak ( , 1964, and Gogala (1967Gogala ( , 1971) studied the ability of fungi to produce indole compounds. Most of the fungi studied synthesized indole compounds, particularly IAA, but the amount of auxins produced, their composition, and the time necessary for their production in detectable amounts differed among different species and even among strains.…”

1986. Analysis by HPLC -mass spectrometry of the indole compounds released by the ectomycorrhizal fungus Hebelorna hiernale in pure culture. Can. J. Bot. 64: [1893][1894][1895][1896][1897]. Indole compounds released by Hebelorna hiernale Bres. in pure culture were studied by cultivating the fungus on a nutrient solution supplemented or not with 1 mM tryptophan. Analytical thin-layer chromatography revealed numerous indole compounds in 7-week-old culture filtrates obtained in the presence of tryptophan. Such compounds were isolated by preparative thin-layer chromatography and purified by high performance liquid chromatography. The most abundant of them, i.e., indolyl-3-acetic acid, indolyl-3-carboxylic acid, and indole-3-aldehyde. were identified by mass spectrometry. Indole-3-aldehyde and indolyl-3-carboxylic acid, which were detected in filtrates throughout the culture period, might result from breakdown of indolyl-3-acetic acid by fungal exocellular enzymes.

La production de composCs indoliques par H. hiernale en culture pure a Ct C CtudiCe en cultivant ce champignon sur une solution nutritive contenant ou non du tryptophane 1 mM. De nombreux composCs indoliques ont Ct C mis en evidence par chromatographie sur couche mince dans les filtrats aprks 7 semaines de culture en prCsence de tryptophane 1 mM. Ces composCs ont Ctk isolCs par chromatographie sur couche mince prkparative et purifiCs par chromatographie liquide haute performance. Les plus abondants d'entre eux, c'est i dire l'acide indolyl-3-acCtique, l'acide indolyl-3-carboxylique et I'indole-3-aldChyde ont Ct C identifiks par spectromCtrie de masse. L'indole-3-aldChyde et l'acide indolyl-3-carboxylique, qui ont Ct C dktectCs tout au long de la culture, pournient provenir de la dkgradation de l'acide indolyl-3-acCtique par des enzymes fongiques exocellulaires.

“…Like many other investigators he found that under certain circumstances, with excised roots, IAA can induce the dichotomous branching of the short roots of pine plants in the same way as is normally the case when such roots are infected by mycorrhizal fungi in natural solls. Ulrich (1960) was not able to produce branching of the roots of Pinus lambertiana with IAA but with indolacetonitrile (IAN) ; on the other hand she found a non-mycorrhizal fungus, a Coprinus species, capable of producing IAA. Earlier this was also demonstrated by N i e 1 s e n (1930) to be true for the mould fungus Rhiz@us suinus (c/ Moser 1959a).…”

“…Mycorrhizal partners of sugar pine, Pinus lambertiana Dougl., added to culture solutions in which intact pine seedlings were growing, failed, with the exception of one seedling, to induce the expected dichotomous branching (Ulrich, 1960b). The effects of indoleacetic acid were also different.…”
