Considering the transfer of genes during endosymbiosis a gene transfer event (at least fundamentally, even if it's a special case), how does the fact that in this case the genes are inside a compartment, affect their gene loss, or incorporation into the host/recipient's genome (in context of gene transfer)?

I would imagine that the loss would be slower, recombination with other transferred genes less probable. But I can't find literature on the same. Any leads?

    $\begingroup$ Could you clarify? What systems are you thinking of? Slower compared with what? $\endgroup$

  • $\begingroup$ Slower compared to gene loss if the genes are in the nucleus. $\endgroup$

  • $\begingroup$ Still don’t follow. Can you give some examples of the two? $\endgroup$

  • $\begingroup$ I don't know if it's true or not. I am assuming that because of compartmentalisation there should be a significant difference in the rate of loss between the two compartments. But I may be very naive and maybe it's trivial that it's not true. What I am asking is for evidence or scientific literature on this topic (because i couldn't find much). $\endgroup$

  • $\begingroup$ Here is an extreme example of rapid total loss of photosynthetic genes from a now parasitic organism. Compare that to the rate of loss (or lack of it) for photosynthetic genes in common photosynthetic plants. Now what I am thinking about is a comparison of this rate of loss in plastid genes, to that of genes incorporated into the nucleus. Think about a situation if those photosynthetic genes were incorporated into the nucleus somehow, directly, instead of being in a endosymbiotic compartment (giving rise to a plastid). $\endgroup$
