NASC Stock Detail Page

NASC ID: N24931

Name: sos5-1

ABRC stock number: CS24931

Description: Hypersensitive to NaCl, KCl, and LiCl but not to CsCl stress; in response to salt stress, the root tips of plants swell and root elongation is arrested, root tips have abnormal cell expansion, thinner walls, and reduced middle lamella; under normal growth conditions, the rate of growth and development of plants is similar to that of wild GERMPLASM_TYPE plants but with shorter siliques and fewer seeds per silique; glabra phenotype: lacks trichomes on leaves and stems; backcrossed three times.

Phenotype

Hypersensitive to NaCl, KCl, and LiCl but not to CsCl stress; in response to salt stress, the root tips of plants swell and root elongation is arrested, root tips have abnormal cell expansion, thinner walls, and reduced middle lamella; under normal growth conditions, the rate of growth and development of plants is similar to that of wild type plants but with shorter siliques and fewer seeds per silique; glabra phenotype: lacks trichomes on leaves and stems. Mutants grown in the presence of 100 mM NaCl display a dramatic short root phenotype and radial swelling of the root elongation zone.ABA at between 0.5 and 2 microM partially and at 5 microM fully suppresses the NaCl-induced phenotype and partially suppresses in the absence of NaCl. Roots are also short and more swollen in media containing 1% sucrose.
