Identification of a cDNA from the Arbuscular Mycorrhizal Fungus Glomus intraradices that is Expressed During Mycorrhizal Symbiosis and Up-Regulated by N Fertilization
A cDNA library was constructed with RNA from Glomus intraradices-colonized lettuce roots and used for differential screening.This allowed the identification of a cDNA (Gi-1) that was expressed only in 3 Pc. Sectional mycorrhizal roots and was of fungal origin.The function of the gene product is unknown, because Gi-1 contained a complete open readin
