Rubiaceae

Called “bedstraw family” in GBIF

Rubiaceae is a family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with interpetiolar stipules and sympetalous actinomorphic flowers. The family contains about 14,200 species in about 615 genera, which makes it the fourth-largest angiosperm family by number of species. Rubiaceae has a cosmopolitan distribution; however, the largest species diversity is concentrated in the tropics and subtropics. Economically important genera include Coffea, the source of coffee; Cinchona, the source of the antimalarial alkaloid quinine; ornamental cultivars ; and historically some dye plants.

Jumping DNA bits help some citrus trees grab scarce iron

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.
