Uptake And Transport

Measurements of ion transport through roots and ion uptake into roots were made following a brief period of water stress induced by wilting in air. The basic processes of photosynthesis, respiration and protein sinthesis did not appear to be affected by this treatment, and uptake of 86Rb and L-leucine to the roots was not reduced. However, transport of 86Rb and L-leucine from root to shoot wasinhibited. Thus the response of the plants to water stress resembles the response to inhibitors of protein synthesis and to abscisic acid, which has been found to be produced in plants subject to water stress.

Uptake And Transport

Cycloheximide inhibits transport of K through barley roots without affecting K uptake and accumulation in the root cells. The inhibitor acts upon protein synthesis but does not appear to uncouple respiration. Requirement of protein synthesis for ion transport through roots is possibly due to involvement of symplasmic transport or vesicular secretion into the xylem.

Qualitative Changes

Maize seedlings respond to heat shock, water stress, abscisic acid treatment, and wounding with the synthesis of stress-specific proteins. Unlike the almost instantaneous (10 min) heat-shock response, a much longer stress exposure is required before the synthesis of water stress induced, abscisic acid induced, or wound-induced proteins. As with heat shock, the protein profile of 24 h water stress induced proteins is consistent between tissue types, whereas seedling tissue response to wounding or heavy metals varies. Wounding of the mesocotyl for 12 h or more results in a complex change (induction and inhibition) in protein synthesis in the growing region, while protein synthesis in the nongrowing region is affected to a much lesser extent.

In The Wild

Protein synthesis and translatable mRNA population changes induced during water stress were studied in leaves of a drought-resistant wild relative of tomato, Lycopersicon chilense, using one- and two-dimensional polyacrylamide gel electrophoresis. Under our experimental conditions, water deficit did not significantly affect total protein synthesis capacity. However, it induced biphasic synthesis of a new set of proteins. These newly synthesized proteins resumed to control levels upon rehydration of the plants. Certain drought-induced proteins also accumulated in leaves subjected to heat shock (39 °C) or exogenous abscisic acid (ABA, 1 mM) treatments. A cDNA library was constructed using poly(A)+ RNA from leaves of plants exposed to drought stress for 4 days. Differential screening of the library identified three groups of clones corresponding to drought- and ABA-induced mRNAs. Northern blot analysis showed that the genes of selected clones respond differently to the different environmental stresses. Our data clearly demonstrate that water stress alters gene expression in L. chilense plants resulting in the synthesis of new proteins, of which several respond to high temperature stress and others to an osmotic effect. These responses are in part modulated by ABA.Key words: abscisic acid, drought, gene expression, Lycopersicon chilense.
