From proteomics to biotechnology. using the resurrection plant eragrostis nindensis to genetically engineer drought tolerant crops
… that could differentiate the desiccation-tolerant non-senescent (NST) leaves from the desiccation-sensitive senescent (ST) leaves. The data presented here illustrate that several important metabolic pathways are significantly reprogrammed, that only a small subset of proteomic-matching …

Selection of Drought-Tolerant Soybean Lines Using a Field Screening Method and Identification of QTLs for Slow Wilting and Nitrogen Fixation Associated With Drought-Tolerance
<p>Drought causes significant yield reductions in soybean. The development of drought-tolerant cultivars is an effective alternative to overcome this abiotic stress. Slow wilting, prolonged nitrogen fixation, and minimal yield reduction under water stress play an important role in evaluating …

Characterising four Cowpea (Vigna unguiculata (L.) Walp.) Mozambican landraces deposited in a seed bank for drought tolerance
… by environmental stress factors, particularly drought. More drought-tolerant crops are therefore urgently required for future improvement of food production in Mozambique. To increase high productivity and sustainability of cowpea there is a need to establish an active local breeding program, …

Determining Water Requirements in Turfgrass Systems
… and use turfgrass cultivars that have known drought tolerance, and also fine-tune and throughout development. A series of field experiments were conducted to determine the water requirements of turfgrass lawn systems with the following objectives: 1) investigate differences in chronic drought …

Adoption, Spatial Patterns, and Behavioral Mechanisms in California Turf Removal Rebate Programs
… participation in the program, while opinions of drought tolerant versus natural turf lawns do. The final paper applies survey methodology and a contingent valuation framework to analyze sensitivity in the household willingness to accept a rebate to participate in the program. Water conservation …

Drought and salinity tolerance of cool-season turfgrasses
… climates, there is an increasing demand for drought and salt tolerant turfgrass. Kentucky bluegrass (Poa pratensis L.), tall fescue (Festuca arundinacea Schreb.), and perennial ryegrass (Lolium perenne L.) are the most commonly used cool season turfgrass species in the northern regions of the …

Leveraging genomic mapping and QTL analysis to enhance drought tolerance of cultivated peanut (Arachis hypogaea L.)
… States, and its productivity is often limited by drought stress. Drought negatively impacts the yield and quality of peanut. Drought stress in peanut causes an annual loss of approximately $520 million in the United States. Improving peanut yield under water deficit conditions is crucial for …

Evaluation of Drought Tolerance and Forage Characteristics of Millet Cultivars
… This thesis describes two studies that evaluated drought tolerance of pearl millet cultivars (Pennisetum glaucum [L.] R. Br) grown for grain. A third study is also included in the thesis that evaluated foxtail millet (Setaria italica [L] Beauv) and pearl millet grown as cover crops and forage …

Plant traits and drought tolerance in the savanna : a Kruger National Park case study
… functional traits that can be associated with drought tolerance/avoidance and to test whether wood density is a good indicator of drought tolerance. The study was carried out in Kruger National Park in the month of June. A number of plant traits including wood density, leaf thickness, leaf life …

Assessment of genetic variations within and between populations of Marama Bean (Tylosema Esculentum (Burchell) Schreiber) based on Microsatellites (SSRS) and Intergenic spacer length variation markers in the Namibian germplasm
… L. Schreiber is a herbaceous perennial drought tolerant legume that is endemic to the arid and semi-arid zones of southern Africa. Its agronomic potential is on the basis of its seed's nutritional composition that is comparable with soybean and peanut, the two mostly consumed legumes. In …

Comparative transcriptomics and co-expression networks reveal tissue- and genotype-specific responses of QDTYS to reproductive-stage drought stress in rice (Oryza sativa l.)
Rice (Oryza sativa L.) is more sensitive to drought stress than other cereals. Particularly during reproductive stages, drought causes yield reductions of 50-80%. With at least 25 million hectares of drought-prone rainfed rice, drought remains a major environmental constraint to rice production. …

Forage Production and Quality of Forage Sorghum Intercropped with Sunnhemp at Different Seeding Rates
… that provide optimal nutrition to cattle and are drought and heat tolerant due to the increasing importance to improve crop water use efficiency in crops grown in the region. Forage sorghum [Sorghum bicolor (L.) Moench] is well-established in the Texas High Plains as a drought tolerant forage for …

PHENOTYPING OF GRAPEVINE ROOT SYSTEM FOR DROUGHT ADAPTATION
Drought events increasingly affect many viticultural regions worldwide, negatively influencing grape yield and quality and threatening the sustainability of the wine sector. Among the available adaptation strategies, the adoption of drought tolerant rootstocks has emerged as one of the most …

Molecular mechanisms of stress tolerance in plants
Environmental stress conditions such as drought, salt stress and pathogenic fungi affect negatively plant growth and productivity. Therefore, it is necessary to search for new genetic components and strategies for improving resistance and tolerance in crops. In the present thesis, we describe two …

Major transitions in the plant tree of life: insights from genes, genomes and traits
… Third, I report the spread and evolution of drought tolerance across the plant phylogeny, a key stressor accompanying plant terrestrialisation. This leads to the discovery that the first land plants and vascular plants were desiccation and drought tolerant respectively. Finally, I detail an …
