psi — Plant Photosystem I excitation energy transfer network (2020)
- Description
Weighted directed network of the light-harvesting Photosystem Ι (PSI) of the plant Pisum sativum. The nodes represent chromophores with different identities (i.e. chlorophyll a, chlorophyll b, β-carotene and derivates, lutein, violaxanthin), while edges represent FRET transfer between chromophores. The link directionality connecting nodes in the PSI network depends on the energy levels of the connected chromophores. The weights correspond to the FRET Efficiency between connected chromophores. Hence a directed edge $(i,j)$ represents the transfer of excitation energy from chromophore $i$ to chromophore $j$, presumably from donor to acceptor (the direction convention of the data file is not documented), weighted by the efficiency of this transfer; most pairs of chromophores (about 80% of the edges) are connected in both directions, with different efficiencies.
