“…For wind-dispersed seeds where the diaspore is a samara (e.g., ash and maple species and species in numerous families of tropical trees and lianas), rate of descent, and therefore dispersal distance, is highly correlated with the square root of wing-loading-the ratio of diaspore mass to wing surface area (Green 1980). Selection on dispersal effectiveness therefore constrains investment in heavy seed-protecting structures and favors investment in (a) more energy-dense lipid reserves over carbohydrates (Lokesha et al 1992) and/or (b) chemical defenses such as alkaloids or lectins that can also be used for energy storage after germination (Kato et al 2012, Liener 1979). However, more nutritious lipid-and protein-rich seeds are also often preferred by seed predators (Reichman 1977).…”

Plant defense theory explores how plants invest in defenses against natural enemies but has focused primarily on the traits expressed by juvenile and mature plants. Here we describe the diverse ways in which seeds are chemically and physically defended. We suggest that through associations with other traits, seeds are likely to exhibit defense syndromes that reflect constraints or trade-offs imposed by selection to attract dispersers, enable effective dispersal, ensure appropriate timing of seed germination, and enhance seedling performance. We draw attention to seed and reproductive traits that are analogous to defense traits in mature plants and describe how the effectiveness of defenses is likely to differ at pre- and postdispersal stages. We also highlight recent insights into the mutualistic and antagonistic interactions between seeds and microbial communities, including fungi and endohyphal bacteria, that can influence seed survival in the soil and subsequent seedling vigor. Expected final online publication date for the Annual Review of Ecology, Evolution, and Systematics, Volume 51 is November 2, 2020.

“…A variety of phytochemical classes were reported in V. surinamensis leaves and seed, as lignans, tannins, y-lactones, propiophenones, butanolides and flavonoids. [14][15][16][17] Ultra-performance liquid chromatography coupled with Electrospray Ionization and quadrupole time-of-flight mass spectrometry (UPLC-ESI-QToF-MS) performed in both negative and positive ionization modes provide a profile of metabolites present in the V. surinamensis raw seed butter. In this case, negative ionization mode was more relevant to evaluate the secondary metabolites profile.…”

Introduction Ucuuba is a tupi denomination that means "tree that produces fatty". This designation is usually applied in the Brazilian Amazon for most species of the botanical genus Virola. 1 Virola surinamensis (Rol.) Warb, known as ucuuba, is considered as a typically Amazonian species and its habitat is the lowlands and igapós. The population thrives in flooded areas, river banks, igarapés and furos, or areas that might be reached by river flooding. 2 Thriving species in this environment are açaí, murumuru, patawa and buriti palms, and ucuuba, samaúba, munguba and rubber trees. It is considered as an important biological, social and economic resource for Amazon, as a key species for biological maintenance of flooded areas, due to its environmental interrelations. 3 In the 18th and 19th centuries, butter extracted from ucuuba seeds was initially used as a lighting fuel by Amazonian riverside communities. 4 However, it was in the 1970s and 1980s that the tree was intensely explored for national wood production. Until 1998, ucuuba was the third most exported and commercialized species, representing almost 50% of riverside communities' family income. 5 This factor led ucuuba to be in the international endangered species list of IUCN. 6 Despite the legal measures in Brazil, in the 1990s and the beginning of 2000s, ucuuba was still the third most exported tree species for the international market of tropical woods. 7 Currently, the species is once more in the spotlight, due to the non-timber potential. Butter extracted from the seeds has high moisturizing potential and, at the same time, a soft texture, rapid absorption and velvet dry touch. These characteristics make the ucuuba butter an interesting ingredient for cosmetic formulations.
