Biosynthesis of the fungal cell wall polysaccharide galactomannan requires intraluminal GDP-mannose.
Jakob Engel et al.
The Journal of biological chemistry, 287(53), 44418-44424 (2012-11-10)
Fungal cell walls frequently contain a polymer of mannose and galactose called galactomannan. In the pathogenic filamentous fungus Aspergillus fumigatus, this polysaccharide is made of a linear mannan backbone with side chains of galactofuran and is anchored to the plasma

Protoplasma, 223(2-4), 203-211 (2004-06-29)
The major noncellulosic polysaccharides and proteoglycans in the coffee bean (Coffea arabica) cell wall are (galacto)mannans and arabinogalactan proteins. Immunological and chemical probes demonstrated that the mannans and arabinogalactan proteins were located continuously across the width of the cell wall

The deep-sea fungus Penicillium griseofulvum produces an extracellular polysaccharide, Ps1-1, when grown in potato dextrose-agar medium. Ps1-1 was isolated from the fermented broth using ethanol precipitation, anion-exchange and size-exclusion chromatography. Ps1-1 is a galactomannan with a molecular weight of about
False positive galactomannan test after ice-pop ingestion.

Endosperms from seeds of different subfamilies of Leguminosae were submitted to sequential aqueous and alkaline aqueous extractions. The extractions from species belonging to the Mimosoideae and Faboideae subfamilies yielded galactomannans with constant Man:Gal ratios, whereas the extractions from Caesalpinioideae seeds
