Sophora moorcroftiana, a Leguminosae shrub species that is restricted to the arid and semi-arid regions of the Qinghai-Tibet Plateau, is an ecologically important foundation species and exhibits substantial drought tolerance in the Plateau. There are no functional genomics resources in public databases for understanding the molecular mechanism underlying the drought tolerance of S. moorcroftian...

Atmospheric drought in lowlands in Slovakia is analyzed on the bases of Standardised Precipitation Index (SPI) and Standardised Precipitation Evapotranspiration Index (SPEI). This paper gives information about the dynamic, intensity, seasonal and territorial differences in occurrence of drought with various intensity: mild (near to normal), moderate, severe and extreme for the period 1961–2011....

Plants co-ordinate information derived from many diverse external and internal signals to ensure appropriate control of gene expression under optimal and stress conditions. In this work, the relationships between catalase (CAT) and H2O2 during drought in wheat (Triticum aestivum L.) are studied. Drought-induced H2O2 accumulation correlated with decreases in soil water content and CO2 assimilati...

Drought stress due to water deficit is a major problem of rice cultivation as a most drought-sensitive crop plant. A rice mutant line (MT58) was developed after mutagenesis of cv. Neda by ethyl methane sulfonate (EMS) and selected for dwarfism (18 cm shorter than Neda). The extent of its molecular changes relative to parental cultivar was assessed by SSR and ISSR markers, and the response of th...

Two rice varieties N22 (drought-tolerant) and Panidhan (drought-susceptible) were studied for the protein profiles under control, moisture stress and abscisic acid (ABA) treatments. Both qualitative and quantitative differences were observed. In control and ABA treatment, the number of polypeptides was more in N22, compared to Panidhan. However, a significant number of polypeptides were induced...

Development of drought-tolerant cultivars is hampered by a lack of effective selectioncriteria. In this research, response of 36 genotypes of rapeseed from seven species of Brassicaincluding B. napus, B. rapa, B. juncea, B. carinata, B. oleracea, B. nigra and B. fruticulosa wasassessed under three moisture levels (no stress, mild stress and intense stress) in the field during2011-2012. Five dro...

Medicago truncatula is a model legume forage crop native to the arid and semi-arid environments of the Mediterranean. Given its drought-adapted nature, it is an ideal candidate to study the molecular and biochemical mechanisms conferring drought resistance in plants. Medicago plants were subjected to a progressive drought stress over 14 d of water withholding followed by rewatering under contro...
