Interspecific reproductive barriers in the tomato clade
MetadataShow full item record
Interspecific Reproductive Barriers (IRBs) preserve species identity by preventing interspecific hybridization, an essential facet of the biological species concept. Wild tomato species (Solanum sect. lycopersicum) are useful for studying interspecific reproductive barriers. Within the tomato clade there are 13 closely related species possessing diverse mating systems and complex IRBs. IRBs can be divided into two types: those occurring before mating (premating barriers) and those operating after mating (postmating barriers). Premating barriers include a variety of floral morphological characters ...
