Correction to: The Barley S-Adenosylmethionine Synthetase 3 Gene HvSAMS3 Positively Regulates the Tolerance to Combined Drought and Salinity Stress in Tibetan Wild Barley (Cells, (2020), 9, 6, (1530), 10.3390/cells9061530)

In the original publication [1], there was a mistake in Figure 2. Spot views C1, C6, C7, C12, C13 and D6 were incorrect. This was an unintentional mistake. At the beginning, we serially numbered all protein spots and screened the protein spots for mass spectrometry analysis. However, when writing MS, in order to facilitate the readers’ comprehension of the results, we re-classified and numbered them according to traits such as tolerances to salt (S), drought (D) and D+S, which caused confusion and misalignment. Here, we once again express our deep apology. We thoroughly examined the current version in light of the original data and made the necessary revisions. As a result, we have changed spot views C1, C6, C7, C12, C13 and D6 in the revised paper. The corrected Figure 2 is shown below. ‘Spot view’ of the abundance of differentially expressed proteins (indicated with green circles) in the leaves of three barley genotypes XZ5, XZ16 and CM72 under drought stress, and salinity stress (200 mM NaCl) and D+S stress conditions. Protein spot IDs refer to numbers in Figure 1C,D and Tables 1 and 2. In the original publication, there was a mistake in Figure S2. Some of the 2D gels in Figure 1 and Figure S2 were the same. For example, Figure 1A (XZ5 under drought) = Figure S2 (b) (XZ5 under drought) and Figure 1B (XZ5 under Salinity) = Figure S2 (c); for clarity and correctness, we have rearranged Figure S2. The corrected Figure S2 is shown below. The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
