Abstract

The objective of this study was to obtain information on the interrelation between polyamine (PA) degradation and diamine oxidase (DAO) activity under salt stress. To identify a quantitative correlation between PA degradation and DAO activity in maize under salt stress, the changes in endogenous free PA levels and DAO activity were analyzed in maize seedling roots, using treatments with different concentrations of NaCl and aminoguanidine (AG, a specific inhibitor of DAO). The results showed that the levels of putrescine (Put), cadaverine (Cad), spermidine (Spd) and spermine (Spm) decreased significantly with increasing salt concentrations. This occurred because salt stress strongly promoted DAO activity to stimulate PA degradation. AG treatment increased the accumulation of endogenous free PAs because of a strong retardation of DAO activity. A close correlation was observed between the changes in DAO activity and the PA contents among various treatments. The results indicated that salt stress could enhance PA degradation, suggesting that DAOs might increase their functions under salt stress.

Abstract

Sorghum (Sorghum bicolor), a drought-tolerant cereal, is the second most important grain crop in Africa after maize (Zea mays). In this study, sorghum proteomes from whole plant organs (leaves, sheaths and roots), as well as cell suspension culture systems were resolved successfully using gelbased proteomics tools. Total soluble proteins (TSP) were extracted from leaves, sheaths and roots, as well as cultured cells. These proteomes were resolved via two-dimensional polyacrylamide gel electrophoresis (2D-PAGE). Proteins were visualized by Coomassie Brilliant Blue (CBB) and identified by MALDI-TOF mass spectrometry (MS). Five different proteomes were studied: total soluble proteome and secretome from cell suspension culture, as well as leaf, sheath and root proteomes from whole plants. Unique protein expression profiles were observed for each of the five proteomes, suggesting specialization of the proteins. Western blot analysis indicated that, as expected, HSP70 protein expression was induced in the roots of the experimental material following salt stress treatments. Cell suspension cultures provide a special research material, particularly for studies related to secreted proteins. The expected secretion of an alpha-galactosidase was also observed. On completion of spot mapping and identification, this proteome data could be used as a research/reference resource by many sorghum and grain scientists worldwide.
