The ant, Aphaenogaster picea, benefits from plant elaiosomes when insect prey is scarce.
Environmental entomology, 2013Myrmecochory is a facultative, mutualistic interaction in which ants receive a protein-rich food reward (elaiosome) in return for dispersing plant seeds. In North American northeastern hardwood forests, Aphaenogaster ants are the primary genus dispersing myrmecochorous plants.

Placing traits into novel evolutionary contexts may profoundly alter their functional roles. Here, we investigated whether the elaiosome, a lipid‐rich appendage located on seeds, retained its role as a seed dispersal trait promoting mutualisms with insectivorous ants following human‐mediated introduction of the elaiosome‐bearing

Elaiosomes on Weed Seeds and the Potential for Myrmecochory in Naturalized Plants
Weed Science, 1990Seeds of plants naturalized in the United States were examined for the presence of elaiosomes. Seeds of 47 species belonging to 13 families (Asteraceae, Boraginaceae, Dipsacaceae, Euphorbiaceae, Fabaceae, Fumariaceae, Lamiaceae, Liliaceae, Poaceae, Polygonaceae, Resedaceae, Rosaceae, and Solanaceae) were found to have elaiosomes, indicating that these ...

Der Bau der Riesenkerne des Elaiosoms von Corydalis cava
Chromosoma, 1941Das Elaiosom von Corydalis cava vergrosert sich in der Hauptphase seiner Entwicklung durch Zellwachstum ohne Zellvermehrung. Die Kerne werden, wie sich durch die Analyse der Heterochromatin- und namentlich der Euchromatinstrukturen wahrscheinlich machen last, hochgradig polyploid.

Sex ratios and the distribution of elaiosomes in colonies of the ant, Aphaenogaster rudis
Insectes Sociaux, 2002Genetic theory predicts that workers in monogynous ant colonies with singly-mated queens should capitalize on higher relatedness with sisters than with brothers by altering the sex investment ratio of a colony in favor of females. Sex investment ratios, however, may also be influenced by the amount of resources available to colonies, in part because ...

Ant-dispersed plants usually produce seeds with appendages (elaiosomes) as reward for ants. Plants that produce high-quality elaiosomes benefit because ants preferentially disperse their diaspores. We therefore hypothesized that seeds and elaiosomes differ in chemical composition in ways that make elaiosomes of high nutritional quality for ants ...

Geographic variations in the correspondence between diaspore phenotypes and disperser behavior are thought to determine the evolution of plant-animal dispersal mutualisms. Helleborus foetidus is a widely distributed plant in Western Europe, which seeds bear a lipid rich elaiosome attracting ant dispersers. Laboratory cross-tests were conducted to check

1. Elaiosomes are lipid-rich appendages on the seeds of some plant species that promote dispersal of the seeds by ants. In this study we investigated the hypothesis that elaiosomes on seeds have converged in composition and attractiveness with the insect prey of ants. 2.

Dispersal by ants in Centaurea corymbosa (Asteraceae): What is the elaiosome for?
Plant Species Biology, 2006Abstract This paper reports on different observations and experiments examining the role of ants in the seed dispersal of the rare and endemic species Centaurea corymbosa .
