Novel Strategies to Manage Selenium Deficiency in Cropping Systems

About this Research Topic

Global food security is one of today’s most pressing issues. Plant stress, which includes abiotic (heat stress, drought, salinity, and heavy metals) and biotic (plant diseases caused by microbes like bacteria, viruses, and fungi) stresses, can significantly reduce crop yield, yet many studies only consider these stressors independently. To better understand how to improve crop productivity, we must focus on these stressors simultaneously, with greater emphasis on their combined effects. The most common combined stressors may include salinity and heat stress, waterlogging and salinity, drought and salinity, which have multiple effects on the anatomical, morphological, physiological, and genetic levels of cultivated crops. Applied nanoparticles have shown promising potential to support crop growth under multiple stressors in a sustainable way. Nano selenium (nano-Se) in particular, has emerged as an alternative fertilizer for sustainable agriculture.

Se-fertilizer has been applied in several countries like Finland, which was the first country to adopt a program of Se-biofortification. Nano-Se-fertilizer is a promising solution for sustainable agriculture under combined stress on cultivated plants. Considering the high interest in nano-Se-fertilizers (especially the biological ones as an emerging alternative fertilizer), the mechanisms and role of Se and nano-Se-fertilizers in mitigating the combined stress on cultivated plants needs thoroughly investigating to justify its application. Different aspects including the cytotoxicity, biochemical, physiological, and genetic studies of applied Se and nano-selenium under combined stress have several unanswered questions.

This Research Topic will focus on the impact of applied Se and nano Se on cultivated plants under combined stresses. We will accept Original Research and Method papers studying physiological, biochemical, anatomical, and genetic parameters, as well as Reviews and Perspectives on future challenges and opportunities for applied Se and Se-nanoparticles in agriculture. Areas covered may include, but are not limited to:

• Use of selenium and nano-selenium for crop nutrition
• Role of selenium and nano-Se under salinity and heat stress
• Impact of selenium and nano-Se under drought and heat stress
• Plant selenium and nano-Se biofortification
• Impact of selenium and nano-Se on crop production under combined stress
• Bio-nano-Se and Se-fertilization
• Nano-Se and selenium in plant-soil interactions
• Nano-Se and Se-fertilizers: their impact on crop production
• Nano-Se and Se: their role under waterlogging and salinity stress
• Nano-Se and Se in contaminated soils
• Nano-Se and Se under biotic and abiotic stresses


Keywords: nano selenium, combined stress, drought, salinity, oxidative stress, nano-fertilizers, heat stress, crop production
