These are mashups, actually, and because the creative content is limited patent protection is the game. From Wikipedia on the first of these: Roundup Ready Soybeans express a version of EPSPS from the CP4 strain of the bacteria, Agrobacterium tumefaciens, expression of which is regulated by an enhanced 35S promoter (E35S) from cauliflower mosaic virus (CaMV), a chloroplast transit peptide (CTP4) coding sequence from Petunia hybrida, and a nopaline synthase (nos 3') transcriptional termination element from Agrobacterium tumefaciens. The plasmid with EPSPS and the other genetic elements mentioned above was inserted into soybean germplasm with a gene gun by scientists at Monsanto and Asgrow. That's some seriously clever genetic engineering ... too bad the patent ran out last year ^_^ (https://en.wikipedia.org/wiki/Genetically_modified_soybean#Roundup_Ready_Soybean https://en.wikipedia.org/wiki/Genetically_modified_soybean#R...). Then again those eeeevil corporate mad scientists coming up with new useful additions to soybeans, the monsters. Bt added by Monsanto. DuPount tweaked the output of the three major fats so the one that goes rancid first has a low proportion. Note that bit about Brazil; I've read they've become a major soybean producer thanks to eeeevil 1st World developed seeds that allow it to grow in harsher, dryer climates. There's been a lot of that. My father mentioned, in the context of a bit of a local drought right here in SW Missouri, USA this year, that even with that maize yields are much higher than they used to be in the best of years. (OK, you know what's evil: burning food for fuel.)
