Plant root development and hormone signalling during drought stress
… plays an important role in plant resistance to drought stress. Drought is one of the primary factors that restrict plant growth and yield, and its threat to crop yields will increase along with the growing food demand by the population of a world experiencing a changing climate. In response to …

Physiological variation of Garry oak (Quercus garryana) seedlings to drought stress
… was to determine physiological differences in drought response among Garry oak (<em>Quercus garryana</em> Douglas ex Hook. [Fagaceae]) seedlings that grow in distinct populations in Washington state, in order to aid in restoration efforts by informing growers of the potential differences …

Beneficial Fungal Secretome and Synthetic Consortia to Improve Soybean Growth During Drought Stress
Beneficial endophytic fungi may improve crop stress tolerance through soil carbon storage, water and nutrient acquisition, and stress mitigation. Our goal was to build a naturally occurring fungal synthetic community (FunSynCom) to improve growth and drought resilience in soybeans. In this study, …

Studies With Triazoles to Alleviate Drought Stress in GreenHouse-Grown Maize (Zea mays) Seedlings
… dry-land farming often exposes crops to drought stress. Although some plant species are well adapted to drought, most crops are not. Drought can reduce plant populations and limit growth and development in ways that have serious yield consequences. Planting at the beginning of the wet …

Phenotypic and genetic variation in the architectural responses of a C4 grass to drought stress
… should be grown on marginal and potentially drought prone acreage to avoid displacement of food production. Therefore, next generation C4 grass feedstocks must be both highly productive and highly drought tolerance. Plant architecture provides a framework for finding a balance between these …

Recombinant Chromosome Substitution Lines as a Source of Genetic Variation for Drought Stress Tolerance in Barley
… associated with traits conferring adaptation to drought-prone environments such as plant cuticular waxes were identified. In addition, a two-dimensional paper growth pouch experiment revealed genotypic variation for root traits such as seminal root elongation rate, root diameter and gravitropism …

Relationships Between Expression of Heat Shock Protein Genes and Photosynthetic Behavior During Drought Stress in Plants
… are expressed in response to environmental stresses. Compared to other kingdoms, plant HSP families are larger, presumably the result of adaptation to a wide range of stresses. Following on an analysis of drought stress characteristics in loblolly pine (Watkinson et al., 2003), expression …

Physiological and Morphological Responses to Drought Stress in Different Cultivation Environments in Wild Type and ABA-deficient Barley
… factors affected by climate change, drought is one of the most critical for plant survival and reproduction, shaping plant morphology and physiology and therefore crop productivity. Although the effects of drought on plants are widely studied, studies are often conducted in controlled …

The role of the BHLH038 transcription factor in the regulation of osmotic and drought stress responses in Arabidopsis thaliana
The most important abiotic stress affecting agriculture worldwide is drought. In order to ensure food supply for the expanding world population two critical tasks must be undertaken; maintenance of crop yield as well as the increase of yield potential. Plants have built up a complex stress response …

High-throughput phenotyping and genetic mapping of drought stress related traits in setaria (Setaria spp) and rice (Oryza spp)
Drought stress is one of the most important and complex abiotic stresses limiting crop yield. Therefore, it is essential to dissect this complex trait and understand mechanisms of drought resistance in the field. In this research, experiments were conducted in Setaria, a model C4 crop, and rice, a …

AGRONOMIC AND PHYSIOLOGICAL CHARACTERS OF PEARL MILLET (PENNISETUM AMERICANUM L. K. SCHUM) GROWN UNDER A SPRINKLER IRRIGATION GRADIENT (DROUGHT, STRESS, INDEX).
… at the end of the experiment. Harvest Index, drought tolerance index, and water use efficiency (WUE) were calculated. Percent crude protein of seeds was analyzed, and photosynthesis was measured in 1984 only. Regression analysis was used to compare the performance of the cultivars for …

INFLUENCE OF THE INTERACTION SCION X ROOTSTOCK ON GRAPEVINE RESPONSE TO DROUGHT STRESS AS A TOOL IN NEW GRAPEVINE ROOTSTOCKS BREEDING PROGRAMS.
… the vine-growing areas experiencing severe drought stress are expected to increase in the coming years. This could affect grape quality and yield, as well as the character and style of wines, and, more generally, the viticultural potential of many regions. Many studies suggest adaptive …

Strategies to overcome drought stress in ornamental plants in Mediterranean climate [Strategie per superare lo stress da siccità delle piante ornamentali in clima mediterraneo]
Anche a seguito del cambiamento climatico, lo stress da siccità rappresenta uno dei principali ostacoli per la crescita e talvolta per la sopravvivenza delle piante. Il problema è particolarmente avvertito nell’area mediterranea che rappresenta un hotspot climatico, in cui gli effetti dei …

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. …

An investigation of the use of exogenous Glycine Betaine and Seaweed Extract to ameliorate drought stress in cutting propagation of Griselinia littoralis and Lavatera x Clementii
… a possibly effective approach for improving the drought tolerance of cuttings. The aim of this study were to test the feasibility of GB and GB+SWE helping cuttings fight drought stress during cutting propagation in glasshouses. The research first examined whether exogenous spray application (GB …

Simulating the Effects of Hydroclimate Stress on BVOC-Chemistry-Climate Interactions in NASA GISS ModelE
Drought is a hydroclimatic extreme that causes perturbations to the terrestrial biosphere which causes biosphere-atmosphere feedbacks. Drought acts as a stressor on vegetation, which causes a unique biogenic volatile organic carbon (BVOC) emission response during severe or prolonged drought. In the …
