The diaspores of many plant species are adapted to dispersal by ants (myrmecochory). The ants carry the diaspores into their nests where the appendages of the diaspores (elaiosomes) are consumed. Little is known, however, about the fate of diaspores in the colony, i.e., whether elaiosomes are consumed only by the larvae or also by the workers.

Reaction of Mutualistic and Granivorous Ants to Ulex Elaiosome Chemicals
Journal of Chemical Ecology, 2006It has been proposed that chemicals on plant elaiosomes aid seed detection by seed-dispersing ants. We hypothesized that the chemical interaction between ants and elaiosomes is more intimate than a generic attraction, and that elaiosome chemicals will attract mutualistic but not granivorous ant species.

Importance of elaiosome size to removal of ant-dispersed seeds
Oecologia, 1996Several studies relate removal of diaspores from different ant-dispersed plant species to the size of their claiosomes. This study is the first one to relate intraspecific variation in claiosome size to removal of diaspores by ants. This approach circumvents the problem posed by interspecific variation in chemistry and morphology of elaiosomes. We used

Development and Function of the Elaiosome in Knautia (Dipsacaceae)
Botanica Acta, 1998Abstract:The fruits of the genus Knautia differ from those of all other Dipsacaceae by the possession of a white, ± hemispherical basal appendage (elaiosome). In a series of field experiments Sernander (1906) demonstrated that, due to this elaiosome, the fruits of Knautia are dispersed by ants.

Structure and function of the elaiosome in some angiosperm species
Flora, 1996Summary The structural and functional characteristics of the elaiosomes were studied in various angiosperm species. The elaiosome varies widely in relation to its anatomical origin, and always contains lipid reserves, sometimes accompanied by starch and proteins.

Symbiosis between plants and ants include examples in which the plant provides shelter and/or food for ants that, in turn, act in the defense or in the dispersion of seeds from the host plant. Although traditionally referred as mutualistic, the results of these interactions may vary with the ecological context in which patterns are involved. A range of

Fatty acids and diacylglycerols from elaiosomes of some ant-dispersed seeds
Phytochemistry, 1989Abstract Lipids were isolated from the elaiosomes of four ant-dispersed herbaceous plants ( Jeffersonia diphylla , Sanguinaria canadensis , Trillium sessile , Dicentra cucullaria ) found in Northern Virginia. Fatty acid methyl esters and trimethysilyl derivatives of diacylglycerols were separated and identified by capillary GC/MS.

Myrmecochory by small ants – Beneficial effects through elaiosome nutrition and seed dispersal
Acta Oecologica, 2012Abstract Seed dispersal by ants (myrmecochory) is a common mutualism in temperate woodlands of the Northern hemisphere. In this paper we highlight the contribution of one of the most abundant ant species of Eastern Central Europe, Temnothorax crassispinus, to myrmecochory. In field and mesocosm studies we found that T.

Summary The spikelet of Urochloa paucispicata has a typical Paniceae structure and it constitutes the unit of dispersal; the base of its lower glume is united to an elongated internode between the lower and the upper glumes, and at maturity, it becomes soft and turgid, developing the elaiosome.

Structure and development of the elaiosome in Myrtus communis L. (Myrtaceae) seeds
Flora - Morphology, Distribution, Functional Ecology of Plants, 2005Abstract Myrtus communis L. (Myrtaceae) is a fleshy-fruited shrub occurring in the Mediterranean area, whose seeds are snail shaped, with a very thick coat and a central elaiosome. This structure is a fleshy and edible appendage responsible of seed dispersal by ants, a phenomenon known as myrmecochory.
