Germplasm Phenotype:

• s1p-3  — s1p-3 mutants exhibit a greater inhibition of primary root elongation in response to NaCl, KCl, LiCl, and mannitol than wild-type seedlings. The salt-sensitive phenotype co-segregates with the s1p-3 T-DNA insertion, and can be partially rescued by a 35S:S1P construct. s1p-3 mutants do not show the proteolytic processing of a 4xMyc:bZIP17 protein from an 84 kD to a 46-kD protein, as observed in wild type seedlings. In addition, several salt-responsive transcripts have more than a 2.5-fold lower transcriptional response in s1p-3 mutants than in wild type seedlings.
