Apomictic Grasses
Are you Phredo's mother?
I'm sure Phredo is a big boy and he can take care of himself and doesn't need your coddling. I suppose you have never seen or heard the heated arguments that grass taxonomists at the Smithsonian sometimes get into. Taxonomy is not for the faint of heart or sissy cry babies. So why don't you go back to your sterile plastic bubble and twiddle your thumbs!!! "Phredo, you broke my heart." Frank Martin wrote in message ... Surely this reply is too astringent and acerbic and not in keeping with the respect due to fellow scientists.

I'm not a student, Buckwheat. I just want you to put your money where you flip mouth is, you superficial smartass. You still haven't answered the question, you ******. I asked for a list of SPECIES in ten different genera not just random list of generic names. Any idiot can randomly throw out the names of genera and you have proven that. Most if not all of the species in those genera ARE NOT APOMICTIC. That makes you the lazy parasite who cannot back the outrageous statements you make. Phred wrote in message ...

In no particular order: Brachiaria, Paspalum, Eragrostis, Poa, Dichanthium, Tripsacum, Cenchrus, Pennisetum, Panicum, Hyparrhenia, Vetiveria, Themeda, Heteropogon, Bouteloua, Bothriochloa, Capillipedium...

Tsk! I see that velociraptors are not the only vicious sharp-toothed
sabre-clawed reptilian throwbacks who live and lurk in the tall grass. Do all your students/professors cringe and cower in corners apon your arrival? I find myself warming to threshers, winnowers, back-burners, gleaners and Round-up applicators. "Cereoid-UR12-" wrote in message . .. Are you Phredo's mother?

It never did happen.
Phredo completely misunderstood what was previously said by nobody. (How appropriate!!!) nobody wrote in message news In order to produce good ears, corn must be planted pretty densely. As I recall, you need to have at least three or four rows to get any ears of corn. But, that is the way man has cultivated the plant... i dont know if wild maize has similar population density requirements. But I wouldnt doubt that wind pollinated plants need to have others nearby in order to set seed. Beverly Erlebacher wrote in message . ..

Yes, those are genera of grasses but which actual species in those genera are apomictic, if any? A list of generic names alone tells us nothing. Try to find by yourself in http://www.google.com (or any other search engine) if you don't believe. It's works better than your discussion...

I included the original statement made in the thread concerning Zea. There
is no mention of apomixis in that genus nor has there been any discovery of it occurring in the genus. If you would rather believe a false claim made by Phredo without any actual proof, then you have learned nothing at all. Once again you have proven to be the arrogant imbecile, Bev, because you willingly believe the wrong person for the wrong reasons. You have been and remain a disappointment not worthy of serious consideration. Zea x Tripsacum hybrids are NOT the same thing as pure lines in the genus Zea. The intergeneric hybrids were not commercially viable. http://www.apomixis.de/APO2001_Abstract_Book.doc. "APOMICTIC MAIZE: PROBLEMS AND PERSPECTIVES Victor A. Sokolov, Irina V. Khatypova The attempts to find genetically controlled apomixis in diploid or tetraploid maize failed. So at our laboratory a course, traditional in such cases, was taken - transfer of a character, necessary from the selection point of view, from the closest relatives by a way of distant hybridization. The closest relative of maize having an apomictic mode of reproduction is tetraploid Tripsacum (Tripsacum dactyloides) 2n=4x=72. So with the purpose of obtaining apomictic maize hybridization of 2n=4x=40 Zea mays with Tripsacum was conducted. The amphidiploid F1 hybrids had 2n=56 (20Zm + 36Td) and were apomicts having a female fertility at the Tripsacum level with a total male sterility. Their backcrosses using 2n=20 and 2n=4x=40 pollen parents allowed to develop a wide set of apomictic lines with reduction of Tripsacum chromosomes to 9. Despite the fact that they were obtained independently all they have the same set of 9 chromosomes of Tripsacum. The further reduction even by one chromosome of Tripsacum leads to the loss of the apomictic mode of reproduction and as a consequence to the loss of all gamagrass chromosomes in subsequent generations. The cytogenetic analysis showed the polygenic character of the genetic system providing the apomictic development in Tripsacum and its hybrids with maize. So we try to obtain from the highly imperfect 39-chromosome hybrids of maize with Tripsacum lines that wouldn’t be inferior to maize in kernel productivity and quality."

If you would rather believe a false claim made by Phredo without any actual proof, then you have learned nothing at all. You're right. I'm so gullible I have absolutely no ability to run my own intellectual life. I'm ineducable. It's not worth wasting your time on me. Once again you have proven to be the arrogant imbecile, Bev, because you willingly believe the wrong person for the wrong reasons. You have been and remain a disappointment not worthy of serious consideration. Gee, why do you keep bothering with us disappointing arrogant imbeciles? Just put me and everyone who irritates you in your killfile. We aren't worthy of your serious consideration, so why give it? You will have a more peaceful life, and the rest of us can continue along in our little playpen here, being imbecilic and amusing each other with interesting stories from real life and the technical literature. Zea x Tripsacum hybrids are NOT the same thing as pure lines in the genus Zea. The intergeneric hybrids were not commercially viable. It seems to be a fairly hot area of research, with many labs involved. Backcrosses showing apomixis have been obtained for some years. While commercially viable lines which are almost entirely Zea, but display apomixis may not yet have been obtained, I would not be surprised to read current papers with promising results considering the great advances in genetic engineering techniques of the past 10-15 years. Very few things in botany are "commercially viable", and commercial viability is hardly a qualifying measure of scientific validity. http://www.apomixis.de/APO2001_Abstract_Book.doc. "APOMICTIC MAIZE: PROBLEMS AND PERSPECTIVES Victor A. Sokolov, Irina V. Khatypova Yeah, still a hot topic in 2001. This paper is about use of standard cross amd backcross techniques, but other researchers are using modern methods of genetic engineering and genomics. Should I believe your brush off, or the evidence that hundreds of researchers around the world still regard the goal of apomixis in maize as worth pursuing? Is it stupid and credulous to believe that some of these researchers may report promising results? I hope Phred will tell us more. He may be rolling his eyes at where his offhand statement has gone, but unlike some posters, he seems to have a pretty good sense of humour, and may be enjoying Cereoid's antics, or even mine. |

Name ten grasses in different genera that are apomictic!!! BRBR
A quick search revealed the fact that many genera of the Poaceae contain apomictic species. These include Pennisetum, Poa, Sorghum, buffelgrass, and others I don't remember. A great deal of research is going on right now to isolate the genes for apomixis in order to develop consistent strains of superior food & forage plants. You might know that such an advanced and widespread family as the Poaceae would have a backup system in case wind pollination doesn't work.
