“…Recent studies, have demonstrated that secondary metabolites, particularly phenolic compounds, perform important signaling and protective functions in plants. Environmental stresses often lead to intensive biosynthesis of phenolic compounds in plants and, as a consequence, they affect humans' and animals wellbeing [1][2][3]. It is noteworthy that the enhancement of plants' tolerance to adverse effects of environmental conditions would result in much higher yields obtained from the currently cultivated fields.…”

Abiotic stress factors are among the major causes of lower crop yields. It is known, that in response to cold and/or osmotic stress, crops activate various defense mechanisms, including morphological, physiological and metabolic adaptations. Secondary metabolism, especially phenolic compounds, seem to be an important factor of stress-induced metabolic re-engineering as their levels are alternated by abiotic stress in plants. Despite the fact, that the nature and function of phenolic compounds was already studied in various plant species, it is important to define tissue-specific changes induced by two most potent abiotic stressors -low temperature and decreased water potential. Moreover, in fields, the appearance of single stress is rather rare. Usually two or more factors are acting in parallel, which may potentially result in different effects. Therefore, the aim of this study was to analyze selected elements of secondary metabolism in roots of germinating soybean seeds under cold stress, osmotic stress and both stresses combined. In addition the effects of constant and persistent stress were compared to those induced by sudden and brief stress appearance, as well as after the post-stress recovery process. In the presented study standard methods for identification and quantification of phenolic acids and isoflavones were used and the antioxidant capacity of the radicle extracts was measured. The phenolic metabolism in plants was greatly intensified in response to cold and osmotic stress and remained at high level during the post-stress recovery. The amount and composition of both phenolic acids and identified isoflavones also changed in stress-and duration-dependent manner. This proves an important role of phenolic compounds in abiotic stress response of germinating soybean seeds and opens up new perspectives for further investigations.

“…Thus, the sprouts, even if strongly degenerated, may become a source of iron in the diet of people suffering from its deficiency [5]. Moreover, it was found that the sprouts still are source of valuable antioxidant species [11], but also an information about the free radicals increased formation in these sprouts appeared [9].…”

“…up to 7.37 ± 0.69 for Augusta variety, and slight decrease from 7.74 ± 0.98 down to 5.54 ± 0.68 for Nawiko variety). Usually, in time of sprouting antioxidants formation is observed, especially in last days of the process, but it can be disrupted in abiotic stress conditions [11,16]. For lupine sprouts, it was observed, how strongly the sprouting conditions influence on the antioxidants formations (Fig.…”

Formation of free radicals' and antioxidants' biosynthesis during seeds sprouting strongly depends on plant growth conditions, especially while sprouts are fortified in iron. The influence of watering with FeSO 4 solution on soybean and lupine sprouting, yield of iron accumulated in plant tissue, as well as free radical (reactive oxygen and nitrogen species) synthesis and antioxidant activity (capacity) were the objective of this study. Optimal iron accumulation and biomass efficiency were obtained for 3 day watering with water, followed by abiotic stress application (Fe 2+ ions). For lupine sprouts, maximal radical formation (up to ~ 5.7 a.u.) took place on the fifth day of culturing in these conditions, while, for soybean sprouts, continuous increase in their activity was observed until the seventh day (up to ~ 5.8 a.u.). Total antioxidant activity in lupine sprouts increased definitely, even more than three times during 7 days of lupine growing, but, for soybean, it was almost steady. The same trend was observed in phenolic compounds and flavonoids contents. For soybean sprouts, these antioxidants were almost steady, while, for lupine sprouts in these conditions, the intensive synthesis of these antioxidants was observed. In response to high iron content applied from the fourth day in the cultivation media, lupine sprouts synthesize low molecular antioxidants effectively. For soybean sprouts, another mechanism of defense against oxidative stress should be expected.

“…Despite the fact that technological parameters of the product were deteriorated, it is worth to consider this material application as an iron supplement for cereal products, when the application of soybean is impossible. genetic transformation [4,5] or by raising plant in stress conditions in high concentration of iron in growth environment [6,7]; however, both of these ways have some limitations. The first one, similar to other genetic crops modifications, is low acceptable in some societies.…”
