(2022-06-13)Drought, insect pests, and diseases pose serious threats to maize production globally. Risks associated with drought are being addressed through the constant breeding of new drought-tolerant maize cultivars. However, under ...
-
(2012-02-14)Abiotic stresses impact cotton (Gossypium hirsutum L.) affecting physiological, molecular, morphological, and agronomic parameters. One of the main yield components in cotton production is the number of bolls per unit ...
-
(2017-07-12)Drought is a recurrent natural hazard that has impacts on agriculture, hydrology, ecosystem, and social-economy. A comprehensive analysis of drought is valuable for drought assessment and mitigation. Oklahoma is a state ...
-
(2022-03-14)Agricultural productivity is severely limited by environmental stresses that affect plants. Environmental stresses can be classified as abiotic or biotic. This study focuses on drought and saline stress, the two significant ...

BACTERIALLY MEDIATED WATER STRESS TOLERANCE IN WHEAT CONFERRED BY PHENAZINE-PRODUCING RHIZOBACTERIA (2017-12-09)The plant microbiome is the community of microorganisms living in association with plants and are considered to be a “second genome,” capable of directly modifying the plant’s biotic and abiotic environment. Predicted ...
-
(2018-07-31)Plants are sessile organisms and are unable to relocate to favorable locations under extreme environmental conditions, and hence they have no choice but to acclimate and eventually adapt to the severe conditions to ensure ...
-
(2015-08-04)Severe droughts have plagued the United States over the last few years. The 2011 Texas drought, the 2012 U.S. drought, and the current California drought have greatly impacted the nation’s economy and agricultural production. ...
-
(Texas A&M University, 2005-11-01)Farming communities in the United States and around the world lose billions of dollars every year due to drought. Drought Indices such as the Palmer Drought Severity Index (PDSI) and Standardized Precipitation Index (SPI) ...
-
(Texas A&M University, 2008-10-10)This research looks at the past century of Texas and New Mexico climate in order to create datasets sufficient for documenting climatic variations. Inhomogeneities in climate records are defined as variations in climatic ...
-
(2015-12-07)Drought has become and continues to be a major concern throughout many areas of the United States. To better manage water supplies, municipalities are constantly in search of ways to conserve and ration water. In this ...
-
(2020-12-03)Drought, a major threat to the health and productivity of both natural ecosystems and agriculture, is expected to increase in frequency and intensity across many regions as a consequence of climate change and repurposing ...
-
(2012-05-04)To date, over 50% of historical tidal marsh habitat in the U.S. has been lost. A widely accepted approach to mitigate the loss of valuable ecological services is marsh restoration, which includes using excavated soil or ...
-
(2014-12-02)Drought is a deficiency in the hydro climatic variable of interest that is experienced for an extended period of time. In many parts of the world, it is a normal, recurring feature of climate and is therefore inevitable. ...
-
(2009-05-15)The relationship between the satellite-based Vegetation Condition Index (VCI) and frequently used agricultural drought indices like Palmer Drought Severity Index, Palmer’s Z-index, Standard Precipitation Index, percent ...
-
A Multi-Decadal Precipitation Evaluation for Namibia Using Satellite, Model, and Ground-Based Data (2019-06-18)Precipitation in southern Africa exhibits high variability with rain often falling in an intense deluge or not at all. Considerable research has gone into understanding what drives precipitation in southern Africa and how ...
-
(2014-04-30)Cotton plant breeders need well-defined phenotypic parameters by which they can select drought tolerant lines as well as correlate phenotypes to allelic polymorphisms in the cotton genome. Soil-moisture availability is ...
-
(Texas A&M University, 2006-04-12)Significant cultivar difference in many water stress responses of zoysiagrass (Zoysia japonica (Steud.) and Zoysia matrella (L.) Merr.) are shown in this study. Of the four cultivars, Palisades was the most water stress ...
-
(2012-07-16)There is an increasing need to improve crop water-use efficiency (WUE) (ratio of whole-plant biomass to cumulative transpiration) due to decreased water availability and increased food and energy demands throughout the ...
-
(2021-05-11)The frequency and severity of both drought events and unintentional wildfires are expected to increase within the next century. In addition to having profound effects on vegetation structure and composition, this is expected ...
-
(2021-09-01)Understanding how factors such as precipitation, nutrients, disturbances, and herbivory alter herbaceous cover in a savanna is imperative for conserving biological diversity and critical savanna ecosystem functions. This ...
