Citrus is a genus of flowering trees and shrubs in the family Rutaceae. Plants in the genus produce citrus fruits, such as citrons, mandarins, and pomelos. Many important citrus crops have been developed through extensive hybridization, including oranges, lemons, grapefruits, and limes, all of which have many cultivars.

Scientists found that 'jumping gene' fragments inserted near an iron-transporter gene in a hardy citrus species act as switches that turn on iron uptake when soil iron is scarce, helping explain why some citrus trees cope with alkaline soils better than others.
