New cellular T-DNAs in naturally transgenic plants

Naturally transgenic plants represent the result of Agrobacterium-mediated gene transfer. T-DNA soil bacteria Agrobacterium integrated into genome is called cellular (cT-DNA) [1]. Today, more than 50 species naturally plants, or natural GMO (nGMO) are known [2, 3]. The function cT-DNA in remains unknown. It assumed that fixation transgenes could give different selective advantages depending on which genes had been plant [4]. In order to clarify this issue, it necessary study plants. Until recently, list nGM contained less 2 dozen species, but a search through genomic and transriptomic sequencing data made possible double [2]. work, we used same approach, looking for whole have appeared NCBI WGS since 2021. We found 14 new among most extended cT-DNAs were Triadica sebifera, Lonicera japonica, maackii. these organized as imperfect inverted repeats. genomes Paulownia fortunei, Apocynum venetum, Elaeagnus angustifolia, Erythroxylum havanense, E. densum, daphnites, cataractarum, Ceriops decandra, Camellia oleifera, Silene uniflora, short containing only opine synthesis found. also estimated approximate age cT-DNAs. first described examples date back Late Paleogene, process continues present. Thus, can conclude GMOs widespread phenomenon, many aspects remain unclear, requiring additional research topic.
