BACKGROUND Although it has been widely accepted that global changes will pose the most important constrains to plant survival and distribution, our knowledge of the adaptive mechanism for plant with large-scale environmental changes (e.g. drought and high temperature) remains limited. METHODOLOGY/PRINCIPAL FINDINGS An experiment was conducted to examine anatomical and physiological plasticity...

Seedlings of maize (Zea mays L. cv WF9 x Mo 17) growing at low water potentials in vermiculite contained greatly increased proline concentrations in the primary root growth zone. Proline levels were particularly high toward the apex, where elongation rates have been shown to be completely maintained over a wide range of water potentials. Proline concentration increased even in quite mild treatm...

We present experiments and theory relating to transpiration through unrestrained hydrogel beads in contact with a water reservoir below air above. Experimentally, we find that saturated shrink until steady state is reached which flows continuously the beads. The size of bead sensitive evaporation rate, depends on relative humidity speed surrounding air, pressure head imposed by fluid reservoir....

Saline stress impairs germination and initial plant growth. However, discontinuous hydration cycles induce osmotic tolerance in seeds can improve the response of maize to saline stress. The objective this study was evaluate action with different salt elicitors on germination, growth, adjustment cultivars. Maize BR 206 BRS 5037 Cruzeta cultivars were subjected following treatments: 0.0 mmol NaCl...

Plants have different responses to salt and drought stresses. They transport several ions balance osmotic potential stomatal closure opening. Ions including inorganic organic cations anions play a crucial role alleviate abiotic stresses (salt drought). Inorganic containing Na+, K+, Mg2+ Ca2+ comprising Cl-, PO42-, NO3-, SO42- great in ion hemostasis response water Organic like acetate, succinat...

Piriformospora indica, a cultivable root colonizing endophytic fungus of Sebacinales, promotes plant growth and confers resistance against biotic and abiotic stress. The fungus has also the ability to colonize the roots of many varieties of plant species. The goal of present study was to clarify the colonization ability of P.indica in artichoke roots and the respond of plant to water stress. Re...

The function of water for plants is crucial, including playing the roles in metabolic reactions. aims this article are to give information on effects drought stress plant morphology, physiology, and biochemistry, as well mitigation methods management production. Plants manage using a mechanism, namely escape, avoidance tolerance. Drought escape ability accelerate flowering or life cycle, reduce...

UNLABELLED The enzymatic activity of Escherichia coli endo-RNase III determines the stability of a subgroup of mRNA species, including bdm, betT, and proU, whose protein products are associated with the cellular response to osmotic stress. Here, we report that the stability of proP mRNA, which encodes a transporter of osmoprotectants, is controlled by RNase III in response to osmotic stress. We...

Aquaporins are a specific type of membrane channel proteins that efficiently transport water molecules and other small molecular substrates in plants. In this study, we isolated the plasma aquaporin gene EuPIP1;2 from Eucommia ulmoides, an important medicinal plant China. The protein was localized on membrane. Quantitative RT-PCR analysis revealed constitutively expressed all analyzed tissues, ...
