Most of these SEMs illustrate the progression of embryogenesis that occurs at the apical meristem throughout most of the life span of flowering plants. This continues in the axillary buds when the terminal apex ceases to initiate primordia.
Unfortunately all these examples show a spiral, alternate phyllotaxis.
Other phyllotaxy are decussate, as in the Common or European Ash (Fraxinus excelsior) and distichous, as in a begonia eg. Begonia scabrida.
Genetically modified crops
In conventional plant breeding some alleles controlling characters such as size of tubers might be stuck together with alleles of desirable characters such as resistance to diseases like Potato Blight. In this case of potato we have bred varieties that have large tubers and therefore poor resistance to Potato Blight. In the genetically modified variety the two characters have been separated providing a large potato along with the "natural" wild type of resistance to blight. No genes have been brought in from species distantly related as would be the case with glowing mice for instance.
Peterkin the Poodle put a pot of tea
in a pram and pushed it for a ride by the sea.
“This tea is pale and weak”, he said,
as folks began to stare,
“So I thought I’d take it out
for a breath of fresh air.”
