Spatial orientation of gynoecium in legumes and beyond: Commentary to the paper of Wang et al. (2021)

The third largest angiosperm family, Leguminosae, exhibits a relatively wide range of variation in morphology of gynoecium. Some of gynoecial patterns found in this taxon are of special interest, as they resemble ones previously described in the earliest angiosperms. The different orientations of carpels in legumes appear easily switchable through changes in flower symmetry and floral meristem sizes. Regardless of orientation of a single carpel with respect to the inflorescence axis, the placenta-bearing suture invariably remains adaxial as related to the floral axis. This conclusion relaxes the existing controversies between the supposed megasporophyll- derived nature of the carpel and observed diversity of placentation in known Mesozoic angiosperms.
Синюшин А.А. Пространственная ориентация гинецея у Бобовых и не только: комментарий к статье Wang et al. (2021). У представителей третьего по величине семейства покрытосеменных, Бобовых (Leguminosae), отмечается значительное разнообразие в структуре гинецея. Некоторые варианты его строения особенно интересны, поскольку сходны с типами, описанными у древнейших покрытосеменных. Вероятно, различные варианты ориентации плодолистиков у Бобовых сравнительно легко переходят друг в друга при изменениях симметрии цветка и размеров флоральной меристемы. Независимо от ориентации единственного плодолистика относительно оси соцветия, несущий семязачатки шов неизменно остается адаксиальным по отношению к оси цветка. Это заключение снимает противоречия между представлениями об эволюции плодолистика из мегаспорофилла и наблюдаемым разнообразием гинецеев у мезозойских покрытосеменных.
