Hidden changes in plant reproduction reveal new clues about evolution of self-fertilization
In flowering plants, the transition from cross-fertilization (outcrossing) to self-fertilization has evolved repeatedly across species. This shift is often accompanied by a well-known set of traits collectively called the "selfing syndrome," including smaller flowers and reduced scent. However, a ne...

In flowering plants, the transition from cross-fertilization (outcrossing) to self-fertilization has evolved repeatedly across species. This shift is often accompanied by a well-known set of traits collectively called the "selfing syndrome," including smaller flowers and reduced scent. However, a new study highlights that important but largely overlooked changes also occur at the microscopic level of pollen biology.
