There were significant reciprocal effects (RE) at a 5% significance level among the parents in relation to days before female flower anthesis, main branch length, fruit width, pulp firmness, soluble solids content, rind thickness, seed length, seed width, and seed mass (Table 3), which allowed suggesting that for the genetic control of these traits, extrachromosomal inheritance or maternal effects were involved.
We have no evidence for the nature of such suspected amplifications, either intrachromosomal or episomic (extrachromosomal), but excision of a region of a chromosome in the form of a plasmid-like amplicon has been previously reported in Leptospira [48].
Episomal vector and Sender virus vector were once thought to be ideal nonintegrating methods, as the former works as extrachromosomal DNA in the nucleus while the latter is a method of transgene-free induction.
