Jeeze I'm just wondering ...Reading that Nick has decided to take the TC leap, just as I was going to turn my phone off . A picture of removing one of the purified tissue scraping and putting it into a large enough syringe , then injecting it into the base of a different Musa using maybe saline solution ? I wonder if you could cross the two plants like that..
The injection would surly not damage the plant that gets the " needle " Just a thought.... I'm sure there is some type of window of opportunity when it should be done. Maybe the 2nd quarter of a sister plant growth cycle ..well before any blooming ..

would or should it be injected into the corm??thats where it all happens right??...psudostems are all they will ever be once they are out of the corm??

I'm not sure how that would work, the cells you inject are already differentiated and so would do nothing.

What you describe will not work with bananas or any plants. The closest low-tech version is grafting (which does not work with bananas), generally there is no exchange of genetic material between rootstock and scion in grafts, but it has been documented, though the result is far from a hybrid. The hi-tech version of what you describe is called protoplast fusion, which is possible, but very difficult and requires not only lots of lab equipment, but great skill and lots of luck.

but what about grafting corms together??the fine line where they meet might produce new or differant offspring

This topic has been discussed at length previously on this website, search for "grafting" and you should be able to find the discussions.

I don't know a lot about banana genetics, but I wonder if you could do in vitro fertilization. I haven't the slightest idea how you would get haploid gametes, but if you could fuse them you could get an embryo going and eventually a plant. Of course at this point we are talking big $$$ and a fancy lab.

Google about vegetative hybridization. Maybe you would be interested.

Hmm,.....do you think you and I would cross/hybridize if we had a blood-transplant then?
Don't think it works that way, haha! :)

It sounds as though making chimeras by mixing cells in TC is probably possible, but doesn't usually happen:

Experimentally Synthesized Plant Chimeras I. In vitro Recovery of Nicotiana tabacum L. Chimeras from Mixed Callus Cultures (http://aob.oxfordjournals.org/content/54/4/503.abstract)

Some gene transfer among cells of a chimera should be possible if the host is infected with a suitable virus or bacterium. But plants don't have anything like the circulating stem cells that help replenish at least some animal tissues.

Getting a plant graft chimera sounds as though it requires having a new shoot meristem start right at the graft boundary, so that the new meristem includes some cells from each.

But I would have to do a bunch more reading before I could hazard a guess as to whether or how any of that applies to grafting bananas.

I'll go ahead and make a bold prediction that in 20 years we will have precise knowledge of trait loci in the banana genome and we will be able to cleave novel traits from one cultivar and insert them into another cultivar. We know that things like resistance to corm weevils, nematodes, and panama disease are genetic as are resistance to the various leaf diseases. With all the difficulty involved in breeding bananas it may just be easier to take the preferred variety and insert the traits you desire into it. We are probably a good 20 years away from it, but it will happen.

I am 29 and I think that when I am old plants probably won't be getting grafted at all. We will just be designing plants like we were coding a computer program.

It sounds crazy, but 50 years ago the Nobel Prize was being awarded to Watson and Crick for discovering the structure of DNA.

I am awaiting the second green revolution

I could not agree with you more ! I can see in the near future a huge change in plants associated with farming . I truly hope some restraint is applied so we dont go to far to quickly with out some sort of study period . Or a quarantine .. reason for this is I can just look out my window and can see the results of some complete idiots greed and total lack of understanding ..
Its a weed ! Some idiot renamed “Florida Snow” and sold in a few retail nursery's as ground cover .. One city here planted it on a 1 mile area in the medium . Then the lawn service cutting the grass cut it and went out and cut single family homes spreading the seeds . Next season there was “Florida Snow “ in homes with different lawn service and even more seeds were distributed ..
Musa thankfully don't spread seed as rapidly as other plants do.. So in that regard we are safe :)
We should all take a step back and realize the weather patterns are changing. Potatoes could become difficult to grow with these temperature changes , But Musa will become easier to grow in cooler areas as the temp keep rising . Yes I'm saying bananas could be the new potato. No reason to not think so !
But wile all this change is occurring we will need lots of luck to continue feeding the planet.. This is not me just sitting here ringing my hands, I can see these weeds “Florida Snow” as a huge wake up call .. Problem is can any one else ? Or will this huge occurrence be passed over as “ Its Pretty” and allow even more invasion to occur..

St. Lucie Extension Office Explains Snow in Florida
Pusley comes in three different species,Richardia grandiflora, largeflower pusley; R. scabra, Florida pusley (yes, it’s a native); andR. brasiliensi, Brazil pusley. Pusley is a small-leaved ground cover with pretty little flowers and is found flowering everywhere this time of year. The flowers are usually white, occasionally pink or lavender and somewhat funnel-shaped. Each flower produces three nutlets and considering there are approximately 20 flowers in each cluster, that’s a lot of seeds.

I know a little off topic but then again it's right on topic.. The first citrus canker was seen as a little browning of some fruits in a grove !

The agricultural revolution I'm looking forward to is in soil ecology. I like to imagine that some day we'll be able to know the entire genome of every strain of microbe in the soil and how they all interact.

Yes, chimeric shoots can grow from callus formed in fusion of the two plants. But how do you feel about the fact that when sowing seeds of the fruit of these chimeric shoots, grow plants with modified properties?
There is "a method of mentoring." It represents a change in the quality of graft under the influence of the stock, or vice versa. This method is designed by the famous Russian breeder Michurin, and with it brought real varieties of fruit. I do not doubt the veracity of the work Michurin. By the way, his work is highly valued genius scientist Luther Burbank.

By the time you have seed, there's been a cycle of pollen and ovule for crossing to have happened in.

Crossing what with what? Is a chimeric plant fertilization by pollen of the same plant. You do not exclude the possibility of formation of the egg and pollen cells of different plants? O `k In this article, on page 146-147 È.Å.Ãëóùåíêî «Âåãåòàòèâíàÿ ãèáðèäèçàöèÿ ðàñòåíèé» Ì:Ñåëüõîçãèç, 1948 (http://imichurin.narod.ru/glushenko/glushenko.htm), You can read about the changes seed progeny scion.

A chimera contains genetically different cells. If a chimeric plant self-fertilizes, and the pollen is from one genetic type and the ovule is from the other, that's just the same as if the two plants that the cells came from had been crossed without creating a graft, let alone a chimera.

That is what I meant. Do you think there interspecific hybridization, which is impossible under normal circumstances.

My guess (and this is pure guess) is that if two species won't hybridize the usual way, in most cases they still won't won't hybridize if you make a chimera first (if they'll even make one). But I would guess that there would be some pairs of species where it would help.

Plants do have circulating hormones and micro-RNAs. So cells in one part of a plant influence the behavior of cells in other parts.

A can-be offspring changes do not occur as a result of sexual hybridization, so that:

This will not lead to hybridization in the conventional sense, which is at the confluence of sex cells. But while the name of the individual properties of different compound, the compound of the physical flesh, and transmitted to offspring?

To get a hybrid, the pollen has to trigger a response from the pistil, the pollen has to react to that response by growing its tube, and so on until the gametes actually meet and fuse. If the characteristics of either pollen or pistil are different because of influences from elsewhere in the plant, that might affect whether they're compatible. My guess is that it usually wouldn't matter, but sometimes would.

Finally I understood the meaning of your post. Unfortunately Google does not translate well, and we can not understand each other.
Yes! On grafting, followed by dusting founded one of the methods to overcome the difficulties in crossing distant hybridization. United plants influence each other may be by circulating hormones or miRNAs, and maybe other things.
I am writing about it, almost every post on this topic. But you somehow rule out the possibility of plant impact on each other (post №12). And get the chimera offspring with new traits without hybridization(post №18)!
