I see what you mean. They are interesting but odd. Quite an interesting insight into developmental biology, I guess, if the assumption is that 1 cell loses pigment and then divides and so the white splodge all comes from a single cell that stopped doing pigment each time?
I don't think they do divide like that.. But the pattern reminded me of controlled cell death around a virus entry point on immune tobacco leaves. So I was thinking some sort of signal from one central cell affecting the plastomes/chronoplasts in the surrounding ones.
That's interesting. So is this pattern more likely to be a sort of pathology (whether it's a virus or some sort of mutation that goes way beyond just loss of pigment into ka-boom cell sabotage), do you think? I guess mostly when you have like a petunia pigment mutation it comes out striped... And when you have a chloroplast mutation you end up with variegation that is somewhat consistent in format between leaves... I wonder what the heck is going on here then.
So they imply it is a naturally occurring mutant, but they do not know how the phenotype came about? Or I didn't spend long enough scrolling to find the relevant bit
