Supplementary figure. Figure showing multiple sequence alignment of OsPIN, AtPIN, AtPILS and OsPILS genes. Sequence alignment show that although PINs and OsPILS genes are auxin efflux carrier, their amino acid sequences are quite distinct from each other. Alignment of PILS genes are starts at the end of the PIN genes. As PILS genes are evolutionarily conserved from algae to higher eukaryotes, PINs and PILS genes are supposed to be existed as single gene and got diversified during the time of evolution as complexity of organism get increased.
