A differentiated structure called "aril" has been described in seeds of several plant species during the course of evolution and might be considered as a supernumerary integument. Besides its ecological function in seed dispersal, the structure also represents a relevant character for systematic classification and exhibits important properties that impart agronomic value in certain species. Little is known about the molecular pathways underlying this morphological innovation because it is absent in currently used model species. A remarkable feature of the seeds of species is the presence of a conspicuous aril. This genus is known for the ornamental, medicinal, and food values of its species. In view of the molecular resources and tools available for some species, we highlight the potential of these species as models for developmental studies of the aril.
在进化过程中，几种植物物种的种子中出现了一种名为“假种皮”的分化结构，它可被视为额外的珠被。除了在种子传播中的生态功能外，该结构也是系统分类的一个相关特征，并且在某些物种中表现出具有农艺价值的重要特性。由于目前使用的模式物种中不存在这种结构，因此对于这种形态创新背后的分子途径知之甚少。某属物种种子的一个显著特征是存在明显的假种皮。该属以其物种的观赏、药用和食用价值而闻名。鉴于某些某属物种可利用的分子资源和工具，我们强调了这些物种作为假种皮发育研究模型的潜力。
