A trypan blue stained fungal network fn with attached sudan IV stained lipid bodies lb. Like Lersten et al. Do symbiotic microbes have a role in plant evolution, performance and response to stress?
Rezanka, T and K. Oleosins, proteinaceous matrices associated with the surfaces of lipid bodies, are thought to endpfitos stability of lipid bodies in seeds of desiccation-tolerant plants to prevent them from coalescing during seed dehydration and germination Murphy,Purkrtova et al.
Unlike Lersten et al. Applied and Enviromental microbiology, 67 The biogenesis and functions of lipid bodies in animals, plants and microorganisms. Color images in the above cited references vividly illustrate lipid bodies associated with hyphae and other structures of endophytic fungi in tissues of native plants. Applied and Environmental Microbiology; Lipid Bodies in Plant Cells To function normally, embryos, seeds and pollen are physiologically programmed to cope with severe desiccation during maturation and storage Liu et al.
Characterization of a Highly Termostable Alkaline phsosphate from the Euryarchaceonpyrococcusabissi. A solution to pollution problems.

Hydration of Cuphea seeds containing crystallized triacylglycerols. Endophyte Microbiome Diversity in Micropropagated Atriplex canescens and Atriplex torreyi var griffithsii. Van Logtestijn, and C. Trypan blue stain reveals a hyaline branched fungal network fhassociated with endofitso, sudan IV stained lipid bodies lb.
Microbial oils have potential commercial value as pzstos supplements, pharmaceuticals, and biofuels Peng and Chen, In both shrub and grass species, lipid bodies were most prevalent in the root meristems, cortex and phloem. Early microscopic studies involved analysis of freehand sections that allowed vivid staining of lipids. Oil bodies in leaf mesophyll cells of angiosperms: Structure and function of seed lipid-body-associated proteins.

Furthermore using modern imaging, molecular and genomic analysis to assess plant interactions with associated endophyte communities could transform understanding of plant carbon metabolism. 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.
Triglycerides as products of photosynthesis. The abundance of endophyte-associated lipids in healthy plant tissues suggests endophyte involvement in carbon oil metabolism and transport.
Lipid bodies are universal components of plant cells and provide a mobilized carbon source for essential biological processes. Revista Pesquisa Agropecuaria Brasileira. Oil plants harvested for food and fuel depend on these lipid bodies. Biodiesel from oilgae, biofixation of carbon dioxide by microalgae: Emerging concepts in plant health management.
DSE fungi are generally characterized by stained or melanized hyphae and microsclerotia Jumpponen and Trappe,which were most prevalent in dormant plants Figure 2a. Considering increased global interest in accelerating production of plant oils to meet 21 st century food and fuel needs, researchers exploring oil production in plants would do well to expand assessments of endophytic fungi which can play a valuable role in managing this important carbon source.
Our objective in this study was to review dual stained images of plant tissues taken from studies examining endophyte distribution and other plant-fungal associations to specifically consider the association between plant lipid bodies and endophytic fungi.
