dc.description.abstract | Salt tolerance is a target trait in plant science and tomato breeding programs. Wild tomato
accessions have been often explored for this purpose. Since shoot Na+/K+ is a key component of
salt tolerance, RNAi-mediated knockdown isogenic lines obtained for Solanum galapagense alleles
encoding both class I Na+ transporters HKT1;1 and HKT1;2 were used to investigate the silencing
effects on the Na and K contents of the xylem sap, and source and sink organs of the scion, and their
contribution to salt tolerance in all 16 rootstock/scion combinations of non-silenced and silenced
lines, under two salinity treatments. The results show that SgHKT1;1 is operating differently from
SgHKT1;2 regarding Na circulation in the tomato vascular system under salinity. A model was built
to show that using silenced SgHKT1;1 line as rootstock would improve salt tolerance and fruit quality
of varieties carrying the wild type SgHKT1;2 allele. Moreover, this increasing effect on both yield
and fruit soluble solids content of silencing SgHKT1;1 could explain that a low expressing HKT1;1
variant was fixed in S. lycopersicum during domestication, and the paradox of increasing agronomic
salt tolerance through silencing the HKT1;1 allele from S. galapagense, a salt adapted species. | es_ES |
