T-DNA could also integrate into transcriptionally competent or transcriptionally silent regions of the plant genome. Early research that characterized the integration pattern of T-DNAs in crown gall tumors indicated that each of the two T-DNAs encoded by an octopine-type Ti plasmid could independently integrate into the plant genome, sometimes in multiple copies (43, 63, 314).

Extensive translation of circular RNAs driven by N 6-methyladenosine. The poly(A) tail plays an important role in maintaining mRNA stability and translation efficiency.116 mRNA stability can be improved by inhibiting exonuclease-mediated mRNA degradation.52 The poly(A) tail can also bind to multiple poly(A)-binding proteins (PABPs) while working synergistically with 5 m7G cap sequences to regulate translational efficiency.146,147 Polyadenylation of engineered mRNA can occur in two ways: i) by traditional enzymatic polyadenylation, adding the poly(A) tail to the 3 end of mRNA, but which does not allow regulation of tail length148; and ii) by designing a fixed-length poly(A) sequence on a DNA template and transcribing the resulting length-controllable poly(A) tail.149, In mammalian cells, actively translated mRNAs generally contain 100250 adenosine residues.117,150 A poly(A) tail of optimal length can improve translation efficiency and mRNA stability.150,151 Studies have shown that when poly(A) tail size increases to 120bp, the expression level of the corresponding protein increases accordingly.
