“…Jasmonic acid and methyl jasmonate are critical regulators of secondary metabolite synthesis. For example, in presence of pathogens or other stress conditions, the concentrations of jasmonic acid in plant tissues increase ( Gutierrez-Gamboa et al., 2021 ; Nabi et al., 2021 ; Kuru et al, 2023 ). Besides jasmonic acid, cytokinins and ethylene are effective on the regulation of secondary metabolites.…”

Plants are the sources of many bioactive secondary metabolites which are present in plant organs including leaves, stems, roots, and flowers. Although they provide advantages to the plants in many cases, they are not necessary for metabolisms related to growth, development, and reproduction. They are specific to plant species and are precursor substances, which can be modified for generations of various compounds in different plant species. Secondary metabolites are used in many industries, including dye, food processing and cosmetic industries, and in agricultural control as well as being used as pharmaceutical raw materials by humans. For this reason, the demand is high; therefore, they are needed to be obtained in large volumes and the large productions can be achieved using biotechnological methods in addition to production, being done with classical methods. For this, plant biotechnology can be put in action through using different methods. The most important of these methods include tissue culture and gene transfer. The genetically modified plants are agriculturally more productive and are commercially more effective and are valuable tools for industrial and medical purposes as well as being the sources of many secondary metabolites of therapeutic importance. With plant tissue culture applications, which are also the first step in obtaining transgenic plants with having desirable characteristics, it is possible to produce specific secondary metabolites in large-scale through using whole plants or using specific tissues of these plants in laboratory conditions. Currently, many studies are going on this subject, and some of them receiving attention are found to be taken place in plant biotechnology and having promising applications. In this work, particularly benefits of secondary metabolites, and their productions through tissue culture-based biotechnological applications are discussed using literature with presence of current studies.

Water deficit is one of the most limiting factors of plant growth and therefore of their yields, in arid and semi-arid regions of the world. The identification of indices that characterize the most drought-tolerant genotypes in an early stage is very useful since it allows us to evaluate the tolerance of large varieties collections in a short time. The objective of this work is to identify the most efficient drought tolerance indicators and to evaluate, from the early stage of plant development, the germination parameters that would be correlated with drought tolerance in the field. If such correlations were identified, it would be possible to screen dozens of genotypes in the laboratory and identify the most tolerant before moving into the field. To attain this objective, two trials were conducted: The first one was conducted in the laboratory to evaluate the germination parameters (germination rate, root length, root number, etc..…) of sixteen North African barley genotypes (Algerians, Tunisians, and Egyptians) at the germination stage, under polyethylene glycol (PEG-6000) induced stress. The second trial was carried out in the field to measure grain yield of the same genotypes, under stressful and non-stressful conditions. The laboratory test revealed significant differences between root lengths of different genotypes within each water regime and between different water regimes (control and PEG-6000 solution). The result obtained showed the superiority of most Egyptian genotypes, especially under stress conditions induced by PEG-6000. The field trial also showed significant differences in grain yields under both water regimes (stressful and non-stressful regimes) and pointed to the high performance of the majority of Egyptian genotypes as well as one Tunisian genotype. The calculated indices such as “stress tolerance index (STI)”, “stress susceptibility index (SSI)”, “yield stability index (YSI)” and “stress tolerance (TOL)” showed variable correlations depending on the index used, and concluded that (STI) and (YSI) are the best indicators of drought tolerance compared to the others. Among all the germination parameters, only one positive correlation between root length (RL) under PEG-induced stress and grain yield under water deficit conditions, in the field was established. This would suggest its effective and beneficial use to select, among dozens of genotypes, the ones that are most tolerant to drought, at the early germination stage.
