Description

Rosaceae, the rose family, is a medium-sized family of flowering plants that includes 4,828 known species in 91 genera.

The name is derived from the type genus Rosa. The family includes herbs, shrubs, and trees. Most species are deciduous, but some are evergreen. They have a worldwide range but are most diverse in the Northern Hemisphere.

Many economically important products come from the Rosaceae, including various edible fruits, such as apples, pears, quinces, apricots, plums, cherries, peaches, raspberries, blackberries, loquats, strawberries, rose hips, hawthorns, and almonds. The family also includes popular ornamental trees and shrubs, such as roses, meadowsweets, rowans, firethorns, and photinias.

Among the most species-rich genera in the family are Alchemilla (270), Sorbus (260), Crataegus (260), Cotoneaster (260), Rubus (250), and Prunus (200), which contains the plums, cherries, peaches, apricots, and almonds. However, all of these numbers should be seen as estimates—much taxonomic work remains.

SI type

The system with the broadest taxonomic distribution, which we term type-1 SI, is gametophytic and based on linked pistil S S-RNase and pollen S S-locus F-box (SLF)/S-haplotype-specific F-box (SFB). So far, type-1 SI has been found in four eudicot families: Solanaceae, Plantaginaceae, Rosaceae, and Rutaceae. After pollination, both S₁- and S₂-RNases can enter pollen tubes and be recognized by S₁- or S₃-SLFs, but only SCF^S₃-SLF complexes can ubiquitinate these S-RNases leading to their degradation by 26S proteasome, with the survived S₁-RNase in S₁ pollen tubes forming the S-RNase condensates (SRCs) resulting in self-pollen inhibition.
