Formation of the female generative structures in Deutzia scarba (Hydrangeaceae)
Vìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Bìologìâ, Ekologìâ, 2005 The development and the structure of the ovule and the embryo sac of the representative of the family Hydrangeaceae Deutzia scarba are investigated. It is established that the ovule of the given species is hemitropic, tenuinucellatic, unitegmic.

Oikos, EarlyView.Wasp communities associated with fig trees, Ficus spp., are a model system to investigate how local and regional processes shape biodiversity across large geographical ranges. We investigated the β‐diversity of fig wasp assemblages associated with three widely distributed Neotropical fig species – F. citrifolia, F. obtusifolia and F. pertusa – using 27

Evolution of plant reproduction: from fusion and dispersal to interaction and communication [PDF]
, 2009 Based on the existing data concerning the evolution of the sexual reproduction, it is argued that the processes of sex differentiation and interactions play a key role in evolution. From the beginning environment and organism are unified.

Oikos, EarlyView.The ability of plants to attract pollinators is context‐dependent, influenced by floral traits, abundance, and resources from the plant community. Indirect interactions through shared pollinators, from competition to facilitation, may lead to varied reproductive outputs in plants, and the mechanisms behind these interactions remain to be fully ...

PLANTS, PEOPLE, PLANET, EarlyView.Holoendoparasites are extremely rare plants that live entirely hidden inside their hosts, with only flowers and fruits visible. We studied Apodanthes caseariae, found in central and South America, parasitizing Casearia sylvestris. Little is known about its life cycle.

The Cinderella tree, Quillaja saponaria – A soap story
PLANTS, PEOPLE, PLANET, EarlyView.Our current understanding of plants has been shaped by the entwining of different cultures. The Chilean soapbark tree, traditionally valued as a source of natural soap, was shown by serendipitous research in France in the 1900s to produce compounds that can boost the immune response to vaccines.
