To make sure that flying pollinators come to flowers to pick up pollen, plants evolved special organs, the nectaries, to attract the animals. Scientists have now identified the sugar transporter that ...

• Background and Aims The occurrence of nectaries in fruits is restricted to a minority of plant families and consistent reports of their occurrence are not found associated with Fabaceae, mainly ...

Ant–plant mutualisms constitute a compelling model of coevolution, whereby plants have evolved specialised structures, notably extrafloral nectaries (EFNs), to entice ants that in turn afford ...
