Photosynthesis plays a key role in the carbon cycle, being the primary mechanism through which carbon dioxide (CO2) is converted into organic compounds by plants, algae, and certain bacteria. On average, terrestrial ecosystems uptake around one-third of anthropogenic CO2 emissions and participate to the mitigation of climate change. Temperature, so...

Peanut (Arachis hypogaea L.) is a globally important oil and food crop frequently grown in arid, semi-arid, or dryland environments. Improving drought tolerance is a key goal for peanut crop improvement efforts. Here we present the genome assembly and gene model annotation for 'Line8', a peanut genotype bred from drought tolerant cultivars. Our ass...

Global climate change poses a significant threat to plant growth and crop yield and is exacerbated by environmental factors, such as drought, salinity, greenhouse gasses, and extreme temperatures. Plant growth-promoting rhizobacteria (PGPR) help plants withstand drought. However, the mechanisms underlying PGPR–plant interactions remain unclear. Thu...

Drought can be considered one of the most severe and complex weather-related natural hazards. It is a relevant stressor for ecosystems, affecting vegetation, ecosystem productivity, and water and carbon cycles, with a complex web of related impacts. Despite the interlink between the spatial and temporal scales of droughts, these two aspects are oft...

Introduction Tigray is one of the food-insecure regions with many people living under the condition of chronic hunger. Proper intervention mechanisms are vital for addressing food insecurity. Yet, food security intervention mechanisms of various levels are not researched well. Besides, previous studies have rarely addressed the objectives of food s...

Cuticular waxes coating leaf surfaces can help plants tolerate drought events by reducing non-stomatal water loss. Despite their role in drought tolerance, little is known about how cuticular wax composition has changed during breeding in Canadian bread wheat (Triticum aestivum L.) varieties. To fill in this gap, flag leaves of the Canadian Heritag...

Advances in informatics, robotics, and imaging techniques make it possible to use state-of-the-art digital reconstruction technologies for high-throughput plant phenotyping (HTPP) affected by stress factors, as well as for the ontology of their structural and functional traits. Digital imaging of structural and functional features of the abovegroun...

Amid increasing concerns about the impact of climate change on financial asset pricing, this paper investigates how drought risk affects stock returns in the U.S. energy sector over a thirty-year period (1990–2019). To this end, we ranked energy companies based on the long-term trend of the Palmer drought severity index (PDSI) to compare stock perf...
Background and Aims Leaf elongation is vital for Poaceae species’ productivity, influenced by atmospheric CO2 concentration ([CO2]) and climate-induced water availability changes. Although [CO2] mitigates the effects of drought on reducing transpiration per unit leaf area, it also increases total leaf area and water use. These complex interactions ...
Both the hydrological extremes, floods and droughts have serious widespread environmental, societal and economic impacts. The complex nature of droughts makes them one of the most challenging natural disasters to identify, assess, predict and mitigate. As droughts develop in different water resources, their impact can propagate from one sector to a...
