tomato? Solanum or Lycopersicon potato was a mutated tomato some 1
someone wrote: the tomato and potato are, indeed, of the SAME genus (I'm sorry dude ... no I'm not). Its is rather old news that the tomato's genus name has changed from Lycopersicon esculentum to Solanum lycopersicum (And it was LycopersicON, dude, NOT LycopersicUM). + + + As far as I know the majority view is that Lycopersicon is an independent genus. However it certainly is not cast in stone. There have been, and likely still are, those who regard the tomato and potato as belonging to the same genus I believe the Tomato is Solanum and not Lycopersicon. I believe this because I hypothesize that some million/s of years ago the Tomato plants of South America, a few of them gained a mutation. And this mutation of a few tomato plants had the tomato fruit buried in the soil so that the fruit became a tuber. And thus was born the first creation of the potato plant. And since Potato plant is a Solanum, then obviously the tomato is a Solanum. Question: do the Paleontologists have any fossil record of the tomato and potato? Does the tomato exist further back in time than the potato? My guess is yes considering the above Hypothesis. And one should be able to duplicate the experiment that Nature already did. One should be able to find a *wild tomato* and by testing thousands of these wild tomatoes one should be able to find one of these wild-tomatoes place its fruit into the ground and become a *tuber*.

[snip] As far as I know the majority view is that Lycopersicon is an independent genus. However it certainly is not cast in stone. There have been, and likely still are, those who regard the tomato and potato as belonging to the same genus Indeed, that is the current classificatory trend. The tomato group is nested very deep in a much larger _Solanum_ clade. It would be hard to recognize it as a separate genus [doing so would seem to require breaking the rest of Solanum up into many small genera]. Recent researchers include not only tomatoes but also the "tree tomato" 'Cyphomandra betacea' and its kin in the genus Solanum. http://newcrop.hort.purdue.edu/newcr...ee_tomato.html http://www.crfg.org/pubs/ff/tamarillo.html [links illustrating "tree tomatoes"] I believe the Tomato is Solanum and not Lycopersicon. Or, "Lycopersicon" is a name that was applied to one particular small subgroup of _Solanum_. I believe this because I hypothesize that some million/s of years ago the Tomato plants of South America, a few of them gained a mutation. And this mutation of a few tomato plants had the tomato fruit buried in the soil so that the fruit became a tuber. No. Tomatoes and potatoes are indeed fairly closely related to one another within the huge genus _Solanum_, but the potato tuber is a modified underground stem, not a fruit. Cultivated potatoes still do flower and fruit [but many varieties set few fruit], and the fruits do still look like small greenish tomatoes. Tomatoes and the potato fruits develop from the ripened ovaries of the flowers, but the potato tubers develop from whole branch shoots. It's a stem, not a fruit. http://waynesword.palomar.edu/vege1.htm http://www.plantkingdom.com/kingdom/...ae/solanum.htm http://www.plantkingdom.com/kingdom/...e/lycprscn.htm http://newcrop.hort.purdue.edu/newcr...99/v4-379.html And thus was born the first creation of the potato plant. And since Potato plant is a Solanum, then obviously the tomato is a Solanum. And so is the eggplant and a great many other plant species including herbs, shrubs, woody vines and even some moderate-sized trees. Some _Solanum_ species are common weeds, and a few are cultivated ornamentals. Most are tropical. http://pi.cdfa.ca.gov/weedinfo/SOLANUMC2.html http://pi.cdfa.ca.gov/weedinfo/SOLANUMB2.htm list some weeds Question: do the Paleontologists have any fossil record of the tomato and potato? Don't know. The following site indicated "no records found" for a search on "Solanum" http://ibs.uel.ac.uk/ibs/palaeo/pfr2/pfr.htm If there is any fossil record for members of this group, it may well just be of fossil pollen grains, which would tell you very little about tubers. Does the tomato exist further back in time than the potato? My guess is yes considering the above Hypothesis. And one should be able to duplicate the experiment that Nature already did. One should be able to find a *wild tomato* and by testing thousands of these wild tomatoes one should be able to find one of these wild-tomatoes place its fruit into the ground and become a *tuber*. There are several wild species of tomatoes and also various wild species of potatoes. Several of the wild potatoes do form tubers. The tubers again are modified stems, not fruits. The many wild potato species also flower and form small tomato-like berries on their above-ground branches. http://www.grida.no/cgiar/awpack/diversit.htm http://ethesis.helsinki.fi/julkaisut...roduction.html http://plants.gardenbed.com/65/6421_edi.asp http://www.zum.de/stueber/ross/potato/herbarium_Ia.html http://www.zum.de/stueber/ross/potato/herbarium_Ib.html http://www.zum.de/stueber/ross/potato/herbarium_II.html http://www.zum.de/stueber/ross/potat...arium_III.html http://www.zum.de/stueber/ross/potato/supplement_A.html[lists of wild potato collections] other misc. links. http://www.ecpgr.cgiar.org/Workgroup...solanaceae.htm http://newcrop.hort.purdue.edu/newcr...99/v4-379.html http://www.keil.ukans.edu/delta/angio/www/solanace.htm http://www.ume.maine.edu/PAA/abstramgen2001.htm http://www.ars-grin.gov/ars/MidWest/NR6/ar99.html cheers |
