Шаблон:Short description Шаблон:Speciesbox
Brassica rupestris is a species of flowering plant in the family Brassicaceae, native to southwestern Italy, and Sicily.[1] The plant is known to grow on vertical limestone cliffs.[2] In the past it was proposed, based on morphology, that Brassica rupestris contributed to the ancestry of either kale or kohlrabi, but DNA evidence shows that it did not.[3]
Taxonomy
Brassica rupestris was described and named by Constantine Samuel Rafinesque in 1810.[1] In 1997 Francesco Raimondo and Pietro Mazzola erected a subspecies, Brassica rupestris subsp. hispida, based on very slight differences including leaf hairiness and silique size, which is not supported by molecular studies.[2]
Subtaxa
The following subtaxa are currently accepted:[1]
- Brassica rupestris subsp. hispida Шаблон:Small – Sicily
- Brassica rupestris subsp. rupestris – southwestern Italy, Sicily
Chemistry
There were a number of substances of note found in the roots and shoots of B.Шаблон:Nbsprupestris. These were tartaric acid ester, reduced glutathione (GSH), ascorbic acid, dehydroascorbic acid, glucobrassicin, and glucoraphanin.[4]
Distribution and habitat
Brassica rupestris subsp. rupestris is found in mountainous areas of Calabria and Sicily, and has been reassessed as Least Concern, while B.Шаблон:Nbsprupestris subsp. hispida is found in a number of stations in Sicily and has been reassessed as Vulnerable.[2] Both subspecies typically live on near-vertical limestone cliffs, with B.Шаблон:Nbsprupestris subsp. rupestris found from Шаблон:Cvt above sea level, and B.Шаблон:Nbsprupestris subsp. hispida found from Шаблон:Cvt.[2]
