“…The statistical analysis in Table 3 showed that plant species, seasons, and their interactions with the amounts of all photosynthetic pigments in the three plant species had highly significant effects (P < 0.01). Our findings were consistent with those of El-Absy [6], Uvalle Sauceda et al [66], Devi et al [67], Khater et al [68], Malik et al [69], Neamah and Jdayea [70], in which the findings likewise revealed seasonal variations had significant effects on all photosynthetic pigments in different plant species. The contents of chlorophyll a (Chl.a), chlorophyll b (Chl.b) and Chl.a+b showed a significant increase in H. muticus type, followed by T. polium and A. setifera species.…”

The present study was undertaken to understand adaptive behavior and the possibility of osmotic adjustment adopted by three plant species to tolerate harsh environmental conditions during the winter and summer seasons based on some soil and plant variables as well as the relationships among them. The plant species studied are Hyoscyamus muticus L. (H. muticus), Anabasis setifera Moq. (A. setifera) and Teucrium polium L. (T. polium) and were collected from Tayma Governorate, Tabuk region, Saudi Arabia. ANOVA results showed that the plant species, depths, and their interaction significantly affected most physicochemical properties of the soil supporting three plant species. Also, the plant species, seasons, and their interaction highly significantly affected photosynthetic pigments and proline contents. The highest values for pH and Ec in A. setifera soil, for Na+, Mg++ and Cl- in H. muticus soil, and for other studied chemical properties in T. polium soil were recorded. Significantly increased water content % was observed in A. setifera soil at 20-40 depth across the winter season. Chlorophyll a (Chl.a), chlorophyll b (Chl.b) and Chl.a+b contents in H. muticus plants and Chl.a/b, total carotenoids, total pigment and proline contents in T. polium plants were significantly increased in comparison to the other plant species. Compared to the winter season, the amount of proline and photosynthetic pigments increased significantly in the summer season. The principal component and biplot analysis displayed that the three plant species were quite separated based on the variables studied, and showed positive correlations among most soil and plant variables, but these associations varied in their degree and consistency. The positive correlations were observed for PC1 with K+, Ca++, HCO3- and SO4-- in soil as well as Chl.a/b, total carotenoids, total pigment and proline in T. polium plants. While PC2 showed highly positively correlated to Na and Mg in soil as well as Chl.a, Chl.b and Chl.a+b in H. muticus plants. As a result, the above soil chemical properties are associated closely with the above plant variables in the two previous plant species. The statistical study shows that due to its adaptive behavior and potential for osmotic adjustment, T. polium type generally adapts better to the dry desert environment and seasonal changes.

Background Bacterial siderophores are chelating compounds with the potential of application in agriculture, due to their plant growth-promoting (PGP) properties, however, high production and purification costs are limiting factors for their wider application. Cost-efficiency of the production could be increased by omitting purification processes, especially since siderophores accompanying metabolites (SAM) often also possess PGP traits. In this study, the metabolism versatility of Pseudomonas sp. ANT_H12B was used for the optimization of siderophores production and the potential of these metabolites and SAM was characterized in the context of PGP properties. Results The metabolic diversity of ANT_H12B was examined through genomic analysis and phenotype microarrays. The strain was found to be able to use numerous C, N, P, and S sources, which allowed for the design of novel media suitable for efficient production of siderophores in the form of pyoverdine (223.50–512.60 μM). Moreover, depending on the culture medium, the pH of the siderophores and SAM solutions varied from acidic (pH < 5) to alkaline (pH > 8). In a germination test, siderophores and SAM were shown to have a positive effect on plants, with a significant increase in germination percentage observed in beetroot, pea, and tobacco. The PGP potential of SAM was further elucidated through GC/MS analysis, which revealed other compounds with PGP potential, such as indolic acetic acids, organic acids, fatty acids, sugars and alcohols. These compounds not only improved seed germination but could also potentially be beneficial for plant fitness and soil quality. Conclusions Pseudomonas sp. ANT_H12B was presented as an efficient producer of siderophores and SAM which exhibit PGP potential. It was also shown that omitting downstream processes could not only limit the costs of siderophores production but also improve their agricultural potential.
