The phenotype of the 35S:GmPK21 transgenic Arabidopsis plants under NaCl treatment. a The pyruvate kinase activity of GmPK21 in the wild type (WT) and the 35S:GmPK21 transgenic Arabidopsis plants. b and c An overview (b) and the primary root length (c) of the wild type seedlings and the 35S:GmPK21 transgenic Arabidopsis seedlings grown in 1/2 MS with or without 200 mM NaCl. d The phenotype of the WT and transgenic Arabidopsis grown in soil under normal condition or under 200 mM NaCl treatment. e The fresh weight of the WT and transgenic Arabidopsis grown under normal condition or under NaCl treatment. f The proline (Pro) and (g) malondialdehyde (MDA) contents of the transgenic and WT seedlings grown under normal condition or under 200 mM NaCl treatment. The data are means ± SD, and statistical significance was determined using Student’s t-tests: **, P < 0.01, *, P < 0.05. WT: the wild type Arabidopsis; L4, L8 and L10 represent 3 transgenic Arabidopsis lines overexpressed GmPK21
