Sub-atomic Evidence of Sugarcane Evolution and Domestication Rachel Jabaily and Maggie Koopman
Slide 2Poaceae: Andropogoneae: Saccarum officinarum x S.spontaneum
Slide 3History of Sugar www.plantcultures.org Arabic "sukkar" and Sanskrit "sharkara" Originally developed in New Guinea (6000 BC), yet edit essentially created in India Traditionally utilized as a part of Indian in religious functions and to treat uncleanliness/gallstones. Alluded to in Sanskrit writings from 600 BC. Bitten at first, then bubbled for sweet water. Bedouin brokers moved to Egypt and the Mediterranean. Real exchanging ports in Italy. Planted in the New World 15 years after Columbus
Slide 4Sugar today Brazil, India, China, Thailand, Pakistan, Mexico, Australia beat makers 70% stick, 30% beet (in any case, generally HFCS)
Slide 5Historical speculations Role of S. barberi, S. sinense in development Crossing amongst Saccharum and other genera? ( Erianthus, Miscanthus, Sclerostacha, Narenga ) Interspecific cross breed source of S. officinarum
Slide 6S. sinense S. barberi S. spontaneum x S. robustum S. edule S. officinarum Modern cultivars
Slide 8Nobelization S. officinarum (female) S. spontaneum (male) F1 High sugar cultivar - happened in the nineteenth century in Java and India from only a couple introductory clones
Slide 9S. robustum, S. officinarum x8 S. spontaneum x10 (exceptionally factor chromosome number)
Slide 10"Sweet" inquiries How does the method of product multiplication (ie. Clonal versus seed setting) add to the hereditary qualities of taming? Does high ploidy number compare to high sweetness? There is by all accounts an absence of information on "wild" populaces of some of these species/cultivars. Does data on regions/sum confound or help clear up the photo? How were analysts at first deluded by morphology/flavenoid information and what different issues can high ploidy number make when attempting to concentrate the cause of yields? Do we know anything about the determination of S. robustum clones to deliver S. officinarum ?
