In wildtype plants (upper), the DNA (blue strands) is methylated (red diamonds) and tightly packed, so the cryptic TSSs are inaccessible. In epigenetic mutants (lower), the DNA is less methylated and...

For exciton-exciton annihilation to occur, two excitons must interact with each other. These interactions are well-characterized for 1D and 2D systems. In a 1D system, we can think of exciton...
