Abstract

The effect of drought and salinity stress on the seedlings of the somatic hybrid wheat cv. Shanrong No. 3 (SR3) and its parent bread wheat cv. Jinan 177 (JN177) was investigated using two-dimensional gel electrophoresis and mass spectrometry. Of a set of 93 (root) and 65 (leaf) differentially expressed proteins (DEPs), 34 (root) and six (leaf) DEPs were cultivar-specific. The remaining DEPs were salinity/drought stress-responsive but not cultivar-specific. Many of the DEPs were expressed under both drought and salinity stresses. The amounts of stress-responsive DEPs between SR3 and JN177 were almost equivalent, whereas only some of these DEPs were shared by the two cultivars. Overall, the number of salinity-responsive DEPs was greater than the number of drought-responsive DEPs. And most of the drought-responsive DEPs also responded to salinity. There are both similarities and differences in the responses of wheat to salinity and drought. A parallel transcriptomics analysis showed that the correlation between transcriptional and translational patterns of DEPs was poor. The enhanced drought/salinity tolerance of SR3 appears to be governed by a superior capacity for osmotic and ionic homeostasis, a more efficient removal of toxic by-products, and ultimately a better potential for growth recovery.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
