摘      要：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;***1;5 sequences from more recently evolved Oryza species(***/*** 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 *** compared homology models for homoeologous OcHKT 1;5-K and OcHKT1;5-L from halophytic *** 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(*** and ***).Progenitor HKT1;5 haplotypes can thus be used as novel potential donors for enhancing cultivated rice salinity *** Asian rice accessions,10 non-synonymous HKT1;5 haplotypic groups *** HKT1;5 haplotypic diversities occur in cultivated indica gene pool compared to *** Haplotypes 2 and 10 occur in mutually exclusive japonica and indica groups,corresponding to haplotypes in *** salt-sensitive and salt-tolerant landraces,*** distinct haplotype partitioning may have originated in separate ancestral gene pools of indica and japonica,or from different haplotypes selected during *** of specific HKT1;5 haplotypes within the 3000 rice dataset may relate to eco-physiological fitness in specific geo-climatic and/or edaphic contexts.
