Exploring the interfaces where plant cells and endophyte cells exchange organic carbon by using modern imaging, molecular and genomic analysis could transform current understanding of plant carbon metabolism.

Hydration of Cuphea seeds containing crystallized triacylglycerols. Two distinct steroleosins are present in seed oil bodies. Root and leaf samples were collected from actively growing grasses and shrubs.

Research Signpost, Kerala, India.

Ergot of rye (Cornezuelo del centeno – Español)

In vitro system to determine the role of Aspergillus ustus on Daucus carota roots. It is well documented that fungal symbionts contribute multiple benefits that enhance tolerance to abiotic and biotic stress, but the mechanisms of inducing stress tolerance are not well understood. Oil bodies in leaf mesophyll cells of angiosperms: A trypan blue stained fungal network fn with attached sudan IV stained endofitoa bodies lb.

Bacterial fruit blotch of cucurbits. More studies are necessary to explore the interfaces where plant and endophyte exchange organic carbon. Stewart’s wilt of corn. Structure and function of seed lipid-body-associated proteins. Do symbiotic microbes have a role in plant evolution, performance and response to stress?

Palm oil hydrolysis catalyzed by lipases under ultrasound irradiation-The use of experimental design as a tool for variables evaluation. Lipid bodies structurally similar to those found in vascular plants are also common in microbes. The extracellular lipase EXL4 is required for efficient hydration of Arabidopsis pollen.

Our observations indicate that plant lipid bodies are frequently, if not always associated with endophytic fungi. Early microscopic studies involved analysis of freehand sections that allowed vivid staining of lipids.

To function normally, embryos, seeds and pollen are physiologically programmed to cope with severe desiccation during maturation endofitoa storage Liu et al. Topics in Plant Pathology.

In leaves, they were most conspicuously present in photosynthetic mesophyll, bundle sheath and cells of the stomatal apstos. Like Lersten et al. The most common forms of lipids stored in plants are triacylglycols TAGtriesters of fatty acids that are attached to glycerol Moellering and Benning, ; Goncalves et al.

Oil or lipid bodies called oleosomes are spherical storage organelles embedded within the cytoplasm of eukaryotes Waltermann and Steinbuchel; ; Martin and Parton, Regeneration of Black Grama Bouteloua eriopoda Torr. Dark septate endophytes; a review of facultative biotrophic root-colonizing fungi.

Lipid bodies associated with melanized hyphae in dormant plants were rare, but the abundance in physiologically active plants was remarkable Figure 2b – d.

Lipid bodies were rarely observed in dormant plants Figure 2a. Lipid body inclusions are clear in the hyaline hypha indicated with a black arrow on the lower right corner. We have also used molecular techniques to demonstrate the presence of complex fungal consortia that associate with plants even under aseptic conditions Lucero et al.

Biology and control of hoongos on male sterile wheat and barley. Two major plant oil classes are recognized: Similar amorphous fungal structures, thought to be derived from yeasts, have been reported in surface sterilized seeds of Atriplex canescens and in micropropagated shoots of Bouteloua eriopoda Osuna and Barrow, and of Atriplex canescensboth of which were demonstrated to contain DNA representing diverse fungal taxa Lucero et al.

We presume that the differences in observations are due to different research objectives our group was primarily interested in distribution of endophytic fungidifferences in imaging Lersten et al. Chemistry, Biological Effects, Biotechnology. Torr Plants via somatic embryogenesis.

Hyaline fungal hyphae remain unstained and clear fh.

Introduction to the Pathogen Groups. Although Sudan IV stain would also reveal lipid bodies associated strictly with the plant, our collective experience suggests this is rare.
