Special Issue Information

Dear Colleagues,

Traditionally, oat has been primarily produced as a multipurpose crop for grain, pasture, and forage, or as a rotation crop in many parts of the world. However, in recent years the interest in oat’s potential benefits in nutrition and health has increased significantly, due in part to its superior and unique combinations of biocompounds.

Oat crop is affected by many biotic and abiotic stresses that influence its growth and development, preventing it from reaching its full genetic potential and performance. In addition, the current climate change scenario is causing irregular and unusual yield instability and production losses. Plant responses to these biotic and abiotic stresses involve complex interactions among the genes, proteins, and metabolites that contribute to plant phenotype plasticity. A holistic interpretation of the mechanisms leading to the resistance/tolerance of oats to their biotic and abiotic constraints is necessary, as is going deeper into the molecular responses. This knowledge will help to develop next-generation oat breeding tools, including physiological, biochemical, genomic, and genetic approaches for a more sustainable oat crop.

This Special Issue intends to bring together cutting-edge research with original research articles, reviews, and commentaries covering research related to resistance to biotic and abiotic stresses in oats, including aspects of agronomy, physiology, molecular biology, biochemistry, histology, genetics, etc., that can contribute to the improvement of this important cereal.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • Reprint: MDPI Books provides the opportunity to republish successful Special Issues in book format, both online and in print.

In order to investigate the abiotic stress (drought) tolerance of oat (Avena sativa L.) with silicon and sulphur foliar fertilisation treatments, and monitor the effect of the treatments on the physiology, production, stress tolerance, plant, and grain quality of winter oat varieties, a field experiment was conducted in the growing season of 2020–2021. As a continuation of our article, published in another Special Issue of Plants, in this publication we evaluate the effect of silicon and sulphur treatments on the quality of winter oats. The whole grain sulphur content was significantly different between varieties. The foliar fertiliser treatments caused greater differences in both the carbon and nitrogen, and sulphur contents in the green plant samples, compared to the differences measured in the grain. Foliar treatments had a significant effect on the sulphur content of both plant samples and grains. Significant differences in the Al, Ba, Ca, Cu, Fe, K, Mn, Mo, Na, Ni, P, Pb, Sr, and Zn contents of oat grains were measured, both between treatments and between varieties. Winter oat varieties did not respond equally to the foliar fertiliser treatments in terms of either macronutrient or micronutrient content. When P, K, Ca, Mg, and S were summarised, the highest values were in the control plots. Significant differences in protein content were identified between winter oat varieties in response to the treatments, but the varieties did not respond in the same way to different foliar fertiliser treatments. Based on our results, we recommend the use of foliar fertilisation in oats in drought-prone areas. Full article
