The Lhc protein family in Arabidopsis (ara), poplar (pop), and rice (ory). A, Lhca (a1–a6) and Lhcb (b1–b7) proteins; B, PsbS and LIL proteins; unrooted cladograms were generated using ClustalW alignments of mature protein sequences; ELIP (LIL1), OHP (OHP1, LIL2; OHP2, LIL6), SEP (SEP1, LIL4; SEP2, LIL5).
