Although breeding system investigations were previously performed in only nine of the 100 Tabebuia species, indications of self‐incompatibility have been found in all of them, and the four species ...

Papers appearing in Heredity have made an important contribution to the understanding of plant mating system evolution. While this includes a wide range of topics, this virtual collection focuses on ...

The genus Ipomoea (Convolvulaceae) has a sporophytic self-incompatibility system that is under the genetic control of a single multiallelic S-locus. Self-incompatibility reactions occur on the stigma ...

Self-incompatibility (SI) in flowering plants is a genetically controlled prezygotic barrier that prevents self-fertilisation and promotes outcrossing. Two principal SI systems dominate angiosperms: ...

Many flowering plants prevent inbreeding and increase genetic diversity by a process called self-incompatibility, in which pollination fails to set seed if the pollen is identified as its own by the ...

Biologists provide evidence for an alternative genetic mechanism that can lead to plants becoming self-pollinators. There are flowering plants that have the ability to self-pollinate, meaning that ...

There are flowering plants that have the ability to self-pollinate, meaning that they can fertilise themselves without a partner. A biological advantage of self-pollination, also known as “selfing”, ...
