4 days ago · Mutualisms between plants and fruit-eating animals were key to the radiation of angiosperms. Still, phylogenetic uncertainties limit our understanding of fleshy-fruit evolution, as in the case of Solanum, a genus with remarkable fleshy-fruit diversity, but with unresolved phylogenetic relationships.
4 days ago · The strong phylogenetic conservatism shown in the color and size of Solanum fruits could limit the influences of fruit-eating animals on fleshy-fruit evolution, highlighting the importance of phylogenetic constraints on the diversification of fleshy-fruit functional traits. Mutualisms between plants and fruit-eating animals were key to the radiation of angiosperms. Still, phylogenetic ...
3 days ago · To become invasive, angiosperms need to be able to reproduce, and for some that will require establishing new pollination mutualisms within their non-native range. Globally, 89.7% of angiosperms require a pollinator for outcrossed seed set (Tong et al., 2023).
2 days ago · Recent phylogenetic studies within big plant genera have resulted in upheavals in formal (e.g. Begonia ) and informal (e.g. Solanum [49,50]) classifications within genera, while investigators in other groups have chosen not to apply infrageneric systems to describe all species relationships due to lack of completeness (e.g. Ipomoea ). Indeed, a ...
3 days ago · 1 INTRODUCTION. Many angiosperms rely on animals (pollinators) to transport pollen between flowers. These species have usually evolved two kinds of attractants: rewards (primary attractants), which satisfy the demands of pollinators, and advertisements (secondary attractants), which start a chain reaction in the sensory apparatus of pollinators that enables them to find flowers.
2 days ago · Angiosperms are basally outcrossing (Allen and Hiscock, 2008), and transition to self-fertilization is the most common evolutionary transition and dominant direction of change in reproductive mode in plants (Stebbins, 1974; Barrett et al., 1996). There is often geographic structure to mating-system variation that suggests self-fertilization may ...
3 days ago · The endosperm is a reproductive tissue supporting embryo development. In most flowering plants, the initial divisions of endosperm nuclei are not succeeded by cellularization; this process occurs ...
