Orange Juice Amino Acids May Reveal Secrets to Quelling Citrus Greening Disease

摘要

Known as Candidatus Liberibacter asiaticus,this microbe causes citrus greeningdisease, also called “Huanglongbing,” or“HLB.” (See article on page 4).Agricultural Research Service chemistAndrew P. Breksa III and University ofCalifornia-Davis professor Carolyn M.Slupsky have compared the amino acidcomposition of juice from commerciallygrown oranges. They used nuclear magneticresonance spectroscopy to studyjuice from oranges grown on either HLBpositivetrees or HLB-negative trees. Theirinvestigation is apparently the first to doso, the scientists say.
