Editorial panamericana, p — Storage lipid dynamics in somatic embryos of Norway spruce Picea abies: 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.

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. Plant tissues stained with trypan blue and sudan Pastoa prior to differential interference contrast microscopy exhibited lipid bodies tightly associated with fungal hyphae and with trypan blue stained fungal networks.

Lipid bodies were rarely observed in dormant plants Figure 2a. Applied and Environmental Microbiology; Early microscopic studies involved analysis of freehand sections that allowed vivid staining of lipids. Contributions of endophytic fungi are too often overlooked in plant physiology studies. Odd-numbered very-long-chain fatty acids from microbial, animal and kingdoms.


Although Sudan IV stain would also reveal lipid bodies associated strictly with the plant, our collective experience suggests this is rare. This amorphous fungal morphology observed among endophytes has been previously described Barrow, Triglycerides as products of photosynthesis. Two distinct steroleosins are present in seed oil bodies. 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.

Briefly, hand sectioned tissues were cleared with potassium hydroxide followed by staining with a solution containing trypan blue, which stains fungal cell walls blue, and Sudan IV, which stains lipid bodies red. Extensive fungal diversity in plant roots. Structure and function of seed lipid-body-associated proteins.

Endosperm cells of hydrated Sporobolus airoides seeds stained with trypan blue and sudan IV. Hyaline fungal hyphae remain unstained and clear fh. Slides containing small secondary roots and leaves were mounted and examined with a Zeiss Axiophot microscope with conventional and differential interference contrast DIC optics at X and X magnification.

Van der Heijden, M. Regulation of fatty acid composition may be one mechanism by which plants regulate tolerance to temperature and moisture stress Volk et al. Sudan IV stained lipid bodies in vascular cells of developing lateral roots of Bouteloua eriopoda. Dual stained, physiologically active roots of B. They are also in stems, fruits and leaves, where they are frequently associated with plastids Lersten et al. Palm oil hydrolysis catalyzed by lipases under ultrasound irradiation-The use of experimental design as a tool for variables evaluation.

These hyphae surround many of the large lipid bodies near the center of the page. Failure to acknowledge the presence of endophytes too envofitos leads to risky assumptions that biosynthesis, regulation, and transport of lipids and other biomolecules found within the plant is exclusively carried out by plant cells.

Sometimes only blue stain, suggestive of fungal chitin, could be detected Figure 1d. Stabilization of soybean oil bodies using protective pectin coatings formed by electrostatic deposition.

Root and leaf samples were collected from actively growing grasses and shrubs.
