“…Proline accumulation is a sensitive physiological index of plant response to various abiotic stresses and plays a positive role in the salt tolerance mechanisms of many crops by contributing to membrane stability (Ashraf & Harris, 2004). In contrast to the results of our study where we found a slight non-significant increase of Kasim et al (2016), on radish (Raphanus sativus). Similarly, our results are consistent with those of Aziz et al (2011) and Latique et al (2013) on Amaranthus tricolor and common bean (Phaseolus vulgaris), respectively.…”

“…Several authors such as (Ahmad et al, 2013;Buchanan et al, 2000;Kasim et al, 2016) have shown that algae maintain membrane integrity by reducing electrolyte leakage. The results of the study of Semida and Rady (2014) showed that soaking bean seeds in propolis or maize seed extract increased the membrane stability index, while reducing membrane lipid peroxidation.…”

“…Many research studies have shown the beneficial effect of seed priming with algae extracts to overcome the salinity problem in agricultural lands (Ibrahim et al, 2014;Kasim et al, 2016;Maiti & Pramanik, 2013;Zavariyan et al, 2015). Algae and their by-products provide an excellent source of bioactive compounds such as protein, carotenoids, essential fatty acids, vitamins, amino acids, minerals, and growth-promoting substances such as phytohormones (auxins, gibberellic acid, cytokinins, etc.)…”

Abiotic stresses are critical environmental constraints leading to a huge reduction and loss of agricultural production worldwide (Ahmad et al., 2012). Today, it is estimated that these constraints cause more than 70% of yield losses in agriculture (Acquaah, 2007). Nearly 20% of the world's cultivated area and almost half of the world's irrigated land are affected by salinity (Kaya et al., 2002). Salinity is a major limiting factor in agricultural production affecting the different stages of plant growth. It limits plant development by affecting various physiologicaland biochemical processes such as photosynthesis, antioxidant

“…In our results, plants subjected to salinity stress either showed a decrease in proline content or the content was not significantly affected. This may be attributed to the replacement of proline by another osmoregulator compound under salinity stress [50,51].…”

Seeds germination and seedlings growth of Cucumis sativus and Solanum lycopersicum were monitored in in vitro and in vivo experiments after application of different concentrations of NaCl (25, 50, 100 and 200 mM). Photosynthetic pigments content and the biochemical responses of C. sativus and S. lycopersicum were assessed. Salinity stress slightly delayed the seeds germination rate and significantly reduced the percentage of germination as well as shoot length under the highest salt concentration (200 mM) in cucumber. Furthermore, root length was decreased significantly in all treatments. Whereas, in tomato, a prominent delay in seeds germination rate, the germination percentage and seedlings growth (shoot and root lengths) were significantly influenced under all concentrations of NaCl. Fresh and dry weights were reduced prominently in tomato compared to cucumber. Photosynthetic pigments content was reduced but with pronounced decreasing in tomato compared to cucumber. Secondary metabolites profiling in both plants under stress was varied from tomato to cucumber. The content of saponins, proline and total antioxidant capacity was reduced more prominently in tomato as compared to cucumber. On the other hand, the content of phenolics and flavonoids was increased in both plants with pronounced increase in tomato particularly under the highest level of salinity stress. The metabolomic profiling in stressful plants was significantly influenced by salinity stress and some bioactive secondary metabolites was enhanced in both cucumber and tomato plants. The enhancement of secondary metabolites under salinity stress may explain the tolerance and sensitivity of cucumber and tomato under salinity stress. The metabolomic evaluation combined with multivariate data analysis revealed a similar mechanism of action of plants to mediate stress, with variant level of this response in both plant species. Based on these results, the effect of salinity stress on seeds germination, seedlings growth and metabolomic content of plants was discussed in terms of tolerance and sensitivity of plants to salinity stress.

“…Still, the treatment had no significant effect on germination rate when plants were subjected to different concentrations of NaCl (from 5 mmol.L −1 to 50 mmol.L −1 ). However, priming radish seeds subjected to 150 mM and 200 mM NaCl with Codium taylorii or Pterocladia capillacea extracts induced molecular changes in the DNA patterns of the plant by the disappearance of some bands and the appearance of other ones [62].…”

The time when plant biostimulants were considered as “snake oil” is erstwhile and the skepticism regarding their agricultural benefits has significantly faded, as solid scientific evidences of their positive effects are continuously provided. Currently plant biostimulants are considered as a full-fledged class of agri-inputs and highly attractive business opportunity for major actors of the agroindustry. As the dominant category of the biostimulant segment, seaweed extracts were key in this growing renown. They are widely known as substances with the function of mitigating abiotic stress and enhancing plant productivity. Seaweed extracts are derived from the extraction of several macroalgae species, which depending on the extraction methodology lead to the production of complex mixtures of biologically active compounds. Consequently, plant responses are often inconsistent, and precisely deciphering the involved mechanism of action remains highly intricate. Recently, scientists all over the world have been interested to exploring hidden mechanism of action of these resources through the employment of multidisciplinary and high-throughput approaches, combining plant physiology, molecular biology, agronomy, and multi-omics techniques. The aim of this review is to provide fresh insights into the concept of seaweed extract (SE), through addressing the subject in newfangled standpoints based on current scientific knowledge, and taking into consideration both academic and industrial claims in concomitance with market’s requirements. The crucial extraction process as well as the effect of such products on nutrient uptake and their role in abiotic and biotic stress tolerance are scrutinized with emphasizing the involved mechanisms at the metabolic and genetic level. Additionally, some often overlooked and indirect effects of seaweed extracts, such as their influence on plant microbiome are discussed. Finally, the plausible impact of the recently approved plant biostimulant regulation on seaweed extract industry is addressed.
