Nagahashi G, Abney G, Doner L
New Phytol . 2018 Apr; 133(2):281-288. PMID: 29681062
Carrots (Daucus carota L.) are a ubiquitous host for arbuscular mycorrhizal fungi whereas sugar beets (Beta vulgaris L.) are a non-host. Root cultures were used to compare the constitutive phenolic...
2.
Nagahashi G, Douds Jr D
Fungal Biol . 2011 May; 115(4-5):351-8. PMID: 21530917
Two hydroxy fatty acids, tentatively identified previously in carrot root exudates, were tested for their effects on hyphal growth of the arbuscular mycorrhizal (AM) fungus, Gigaspora gigantea (Nicol. and Gerd.)...
3.
Nagahashi G, Douds Jr D
Mycologia . 2010 Dec; 96(5):948-54. PMID: 21148915
Light and chemical components of the host root exudate can induce hyphal growth and branching of arbuscular mycorrhizal fungi. Compounds that induce the same morphogenetic or biochemical response as light...
4.
Douds Jr D, Nagahashi G, Hepperly P
Bioresour Technol . 2009 Dec; 101(7):2326-30. PMID: 20031395
On-farm production of arbuscular mycorrhizal [AM] fungus inoculum can be employed to make the benefits of the symbiosis more available to vegetable farmers. Experiments were conducted to modify an existing...

Gachomo E, Allen J, Pfeffer P, Govindarajulu M, Douds D, Jin H, et al.
New Phytol . 2009 Aug; 184(2):399-411. PMID: 19659660
* Here, nitrogen (N) uptake and metabolism, and related gene expression, were analyzed in germinating spores of Glomus intraradices to examine the mechanisms and the regulation of N handling during...

Bucking H, Abubaker J, Govindarajulu M, Tala M, Pfeffer P, Nagahashi G, et al.
New Phytol . 2008 Aug; 180(3):684-695. PMID: 18694446
* Root exudates play a key role during the presymbiotic growth phase and have been shown to stimulate hyphal branching and the catabolic metabolism of arbuscular mycorrhizal (AM) fungal spores....

Nagahashi G, Douds Jr D
Mycol Res . 2007 Jun; 111(Pt 4):487-92. PMID: 17544057
Two morphologically distinct hyphal branching responses by the AM fungus, Glomus intraradices, were stimulated by separated components of carrot root exudate. Complex branching up to the sixth order was induced...
8.
Nagahashi G, Douds Jr D
Mycol Res . 2004 Oct; 108(Pt 9):1079-88. PMID: 15506019
Unlike previous reports that have shown that water soluble and volatile compounds from roots or root exudates play an important role in precolonization events during arbuscular mycorrhizal (AM) fungus-host root...
9.
Nagahashi G, Douds Jr D
Mycol Res . 2003 Oct; 107(Pt 9):1075-82. PMID: 14563135
The first action spectrum for a photo-induced response of an arbuscular mycorrhizal fungus is reported. At low light intensity, the responsive wavelengths for light-induced hyphal branching of the primary germ...

Gadkar V, David-Schwartz R, Nagahashi G, Douds Jr D, Wininger S, Kapulnik Y
FEMS Microbiol Lett . 2003 Jun; 223(2):193-8. PMID: 12829285
Soluble factors released from roots of the pre-mycorrhizal infection (pmi) myc(-) tomato mutant M161 were analyzed and compared with normal wild-type released factors. Aseptic whole exudates from the M161 mutant...
