Mazutaur These universal components of eukaryotic cells provide a rapidly mobilized lipid source for many important biological processes Martin and Parton, ; Rezanka and Sigler, Applied and Enviromental microbiology, 67 Oils serve as a carbon and energy reserves and are precursors for membrane lipid and steroid biosynthesis in plants Hanisch et al. Applied and Environmental Microbiology; Hyaline fungal hyphae remain unstained and clear fh. DSE fungi are generally characterized by stained or melanized hyphae and microsclerotia Jumpponen and Trappe,which were most prevalent in dormant plants Figure 2a. This is novel because it highlights a largely unexplored possibility that oils in plants are produced and managed, in full or in part, by endophytic fungi. Stable oil bodies sheltered by a unique oleosin in lily pollen.

A wide range of economically important plants have been reported to harbor endophytes. In these symbiotic mutualisms, both host and symbiont gain benefits from the association.
The fungus obtains nutrients form its host and in return it provides protection from abiotic environ- mental stresses and biotic stresses pest and insect attacks to its host plant. Endophytes have been shown to confer enhanced fit- ness to their hosts such as enhanced til- lering, drought tolerance, root growth, overall enhanced plant growth.
This work describes the detection, isolation and genetic transformation of an endophytic fungus, Acremonium implicatum, from Brachiaria brizantha accession CIAT The results open possibilities for exploiting the quali- ties of an introduced gene as a reporter and study the interactions between A. Furthermore, it also provides options to use a transformed A. Key words: genetic transformation, gene reporter, green fluorescent protein GFP , plant-endophyte interaction.
