Diversity of Sodium Transporter HKT1;5 in Genus Oryza
Original language description
Asian cultivated rice shows allelic variation in sodium transporter, OsHKT1,5, correlating with shoot sodium exclusion (salinity tolerance). These changes map to intra/extracellularly-oriented loops that occur between four transmembrane-P loop-transmembrane (MPM) motifs in OsHKT1,5. HKT1,5 sequences from more recently evolved Oryza species (O. sativa/O. officinalis complex species) contain two expansions that involve two intracellularly oriented loops/helical regions between MPM domains, potentially governing transport characteristics, while more ancestral HKT1,5 sequences have shorter intracellular loops. We compared homology models for homoeologous OcHKT1,5-K and OcHKT1,5-L from halophytic O. coarctata to identify complementary amino acid residues in OcHKT1,5-L that potentially enhance affinity for Na+. Using haplotyping, we showed that Asian cultivated rice accessions only have a fraction of HKT1,5 diversity available in progenitor wild rice species (O. nivara and O. rufipogon). Progenitor HKT1,5
