“…ABA is a major hot topic of drought research, and recently several studies are performed to determine its role in drought in relation to several drought-related molecules: protective proteins, NO, ROS, leaf and root growth, osmotic adjustment, BABA, ROS, and antioxidants [79, 82, 86, 95]. Additionally, in a recent study alginate oligosaccharides (AOS) prepared from degradation of alginate were shown to play a role in enhancing drought resistance in T. aestivum growth period by upregulating the drought tolerance related genes involved in ABA signal pathway, such as LEA1, SnRK2, and pyrroline-5-carboxylate synthetase gene (P5CS) [97]. …”

The genus Triticum includes bread (Triticum aestivum) and durum wheat (Triticum durum) and constitutes a major source for human food consumption. Drought is currently the leading threat on world's food supply, limiting crop yield, and is complicated since drought tolerance is a quantitative trait with a complex phenotype affected by the plant's developmental stage. Drought tolerance is crucial to stabilize and increase food production since domestication has limited the genetic diversity of crops including wild wheat, leading to cultivated species, adapted to artificial environments, and lost tolerance to drought stress. Improvement for drought tolerance can be achieved by the introduction of drought-grelated genes and QTLs to modern wheat cultivars. Therefore, identification of candidate molecules or loci involved in drought tolerance is necessary, which is undertaken by “omics” studies and QTL mapping. In this sense, wild counterparts of modern varieties, specifically wild emmer wheat (T. dicoccoides), which are highly tolerant to drought, hold a great potential. Prior to their introgression to modern wheat cultivars, drought related candidate genes are first characterized at the molecular level, and their function is confirmed via transgenic studies. After integration of the tolerance loci, specific environment targeted field trials are performed coupled with extensive analysis of morphological and physiological characteristics of developed cultivars, to assess their performance under drought conditions and their possible contributions to yield in certain regions. This paper focuses on recent advances on drought related gene/QTL identification, studies on drought related molecular pathways, and current efforts on improvement of wheat cultivars for drought tolerance.

“…Applications in the nutrient solution of 1-2 mM (170-240 mg/L) GA in soybean under low temperatures [22] or applications of 0.75-1 mM (127-255 mg /L) GA in rice under salinity [20] increased the relative growth rate compared to the control. In the case of SoA, previous soaking of wheat seeds with 1000 mg/L alginate-derived oligosaccharide under cadmium toxicity [52] and 1000 mg/L alginate-derived oligosaccharide sprayed in rice plants under water stress [53], enhanced the FW. Application of 100 mM (1.82× 10 4 mg/L) MA in the nutrient solution of wheat seedling with high salinity increased the root dry weight [12] and application of 15-30 mM (2.7×10 3 -5.4×10 3 mg/L) MA by spray in maize leaves with high salinity increased the root and shoot dry weight [54].…”

“…Contrary to the results obtained, several authors reported an increase of total SOD activity after the application of GA and SoA in plants. Application of 1-2 mM (170-240 mg/L) GA in soybean grown in normal and cold stressed condition [22] and the application of 1000 mg/L alginate derived oligosaccharides in wheat grown in normal, drought and Cd stressed conditions [52,53], increased the SOD activity. In the case of SA, contradictory results have been found.…”

1 1 2 3 4 5 6 7 8 1 2 AbstractThe beneficial effects of seaweed extracts have been related to plant growth regulators present in seaweeds. However, algae extracts comprise other organic compounds such as phenols, mannitol, alginates, laminarins and fucoidans that may have a relevant role regarding abiotic stress tolerance due to Fe deficiency. Therefore, we evaluated the individual effect of these organic compounds on the mitigation of Fe deficiency applying a range of concentrations (x1/10, x1, x10) in agar Petri dishes (in tomato seeds) and in the nutrient solution of a hydroponic system (tomato plants). Germination and plant growth promotion, root morphology, chlorophyll content and antioxidant activity were determined.Results showed that the lowest concentration x1/10 and phenolics, laminarin and fucose compounds contributed to increase the tolerance to Fe deficiency in tomato plants.

“…Anti-drought stress; AOS up-regulated genes involved in ABA signal pathways, such as late embryogenesis abundant protein 1 gene (LEA1), psbA gene, Sucrose non-fermenting 1-related protein kinase 2 gene (SnRK2) and Pyrroline-5-Carboxylate Synthetase gene (P5CS) [32] Seaweeds have long been and widely used as sources of organic matter and fertilizer nutrients to increase plant growth and yield for centuries. Numerous commercial seaweed extracts are available for use in agriculture and horticulture.…”

“…Zhang et al (2013) reported that AOS induced root development as well as promoted the generation of nitric oxide (NO) in the root system [31]. Furthermore, Liu et al (2013) reported that AOS, which prepared from degradation of alginate enhanced Triticum aestivum L. tolerance to drought stress [32].…”

Abstract. Alginate oligosaccharides (AOS) have been known as a natural material with a wide variety of biological activities, and used for a long time. The evidence of using AOS to confer health benefits have been documented. The isolation and characterization of the properties, biological activity as well as the applications of AOS in various fields have been studied recently. In present work, we provide the recent research of AOS, particularly focusing on the applications in food and medicinal industry. This review also describes some experimental models, application and discuss the functional and biological mechanisms of AOS. In conclusion, AOS promotes beneficial effects on the immuno-metabolic response to various infectious diseases as well as it is promising as a biomaterial for functional foods and medicinal drugs development.
