Effect of salt stress on contents of soluble sugar (a) and Proline (b) in shoot of Dongdao-4 and Jigeng-88 seedlings grown at normal and salt stress conditions. Expression levels of putative proline synthase genes (Os05g0455500 and Os01g0848200; c and d), transporter genes (Os03g0644400 and Os07g0100800; e and f) in the two rice genotypes were analysed. Total RNA was extracted from rice seedlings grown under control and salt stress conditions for one week. Transcript levels were measured by real-time PCR. Actin was used as an internal control. Error bars are calculated based on three biological replicates. Data are means ±SE (n ≥ 4). Means with different letters are significantly different (P < 0.05) within the same treatments. Asterisks (*) indicate significant differences between control and salt stress of the same genotype which were determined by Student’s t-test (** 0.001 < P < 0.01, *** P < 0.001)
