Elaiosomes (Ancient Greek: ἔλαιον élaion "oil" + σόμα sóma "body") are fleshy structures that are attached to the seeds of many plant species. The elaiosome is rich in lipids and proteins, and may be variously shaped. Many plants have elaiosomes that attract ants, which take the seed to their nest and feed the elaiosome to their larvae.

2022年12月22日 · An elaiosome is a small structure attached to a seed. It consists of dead cells and a lot of lipids, or fats. In fact, the prefix “elaio” means oil. These small structures may have other nutrients as well, including proteins, vitamins, and starch. Although it is not quite accurate, some people call seed elaiosomes arils.

‘Elaiosome’ is a collective functional term (Warburg, 1892; Sernander, 1906) encompassing appendages or seed surface structures that are anatomically described more accurately as arils, arillodes, caruncles, funicles, strophioles, or sarcotesta.

2021年7月21日 · Elaiosome is an organelle that stores fat and is therefore rich in oil. It is a fleshy structure abundant in lipid s and protein s. It occurs in seed tissues (e.g. chalaza, funiculus, hilum, raphe-antiraphe) or fruit tissues (e.g. exocarp, receptacle, flower tube, perigonium, style, spicule). 1 It may vary in shape.

…white appendage known as an elaiosome. The appendage is attractive to ants, which aid in seed dispersal. Carex have food bodies (elaiosomes) at the base of the perigynium for ants, …

Elaiosomes are fleshy structures that are attached to the seeds of many plant species. The elaiosome is rich in lipids and proteins, and may be variously shaped. Many plants have elaiosomes that attract ants, which take the seed to their nest and …

1996年4月1日 · In Chelidonium majus the elaiosome originated from raphe cells, whereas in Mercurialis annua and Ricinus communis, it arose from the external integument of the seed in the form of an appendage in the micropyle area. In Ricinus communis the parenchyma cells are larger and have walls with pectin thickenings interrupted by pits.

elaiosome (plural elaiosomes) (botany) A fleshy structure rich in lipids attached to the seeds of many plant species, usually to attract ants that disperse the seeds.

2024年7月26日 · Segmentation of elaiosomes using only image analysis is difficult, and this makes it impossible to quantify the elaiosome phenotypes. This study proposes a new approach for semi-automated detection and segmentation of elaiosomes in milk thistle seed using the Detectron2 deep learning algorithm.

2019年5月3日 · Elaiosomes are highly specialized nutrient-rich structures that are attached to the seeds of many plant species. The term elaiosome was introduced for the first time by Sernander (1906) to refer to all fleshy and edible appendages of the diaspore dispersed by ants.
