“…Application of halophilic/halotolerant plant growth-promoting bacteria in stressed soil is the most useful and environmentally friendly approach to increase the productivity and health of crops as well as enhance the soil system in the long term ( Alexander et al, 2019a ; Fazeli-Nasab and Sayyed, 2019 ). Plant roots secrete various nutrient substances (∼40% of photosynthetic products) known as root exudates, that play a significant role in the attachment and growth of various endophytic and free-living bacteria ( Wang et al, 2016 ). Some of these bacteria enhance the plant growth and health even under stress conditions.…”

Halotolerant PGPR Stenotrophomonas maltophilia BJ01 Induces Salt Tolerance by Modulating Physiology and Biochemical Activities of Arachis hypogaea

Arachis hypogaea (Peanut) is one of the most important cash crops grown for food and oil production. Salinity is a major constraint for loss of peanut productivity, and halotolerant plant growth promoting bacteria not only enhance plant-growth but also provide tolerance against salt stress. The potential of halotolerant bacterium Stenotrophomonas maltophilia BJ01 isolated from saline-soil was explored to enhance the growth of peanut plants under salt stress conditions. Interaction of S. maltophilia BJ01 enhances the growth of the peanut plants and protects photosynthetic pigments under salt stress. Lower electrolyte leakage (about 20%), lipid peroxidation (2.1 μmol g –1 Fw), proline (2.9 μg mg –1 Fw) content and H 2 O 2 (55 μmol g –1 Fw) content were observed in plants, co-cultivated with PGPR compared to untreated plants under stress condition. The growth hormone auxin (0.4 mg g –1 Fw) and total amino acid content (0.3 mg g –1 Fw) were enhanced in plants co-cultivated with PGPR under stress conditions. Overall, these results indicate the beneficial effect of S. maltophilia BJ01 on peanut plants under salt (100 mM NaCl) stress conditions. In conclusion, bacterium S . maltophilia BJ01 could be explored further as an efficient PGPR for growing legumes especially peanuts under salt stress conditions. However, a detailed agronomic study would be needed to ascertain its commercial role.

“…These findings pointed to endophytes as the main cause of excessive rhizogenesis. Indeed, it is known that endophytes can alter the root system architecture by disrupting polar auxin transport (Wang et al, 2016). Even more interestingly, endophytes are responsible for high saponin contents in other species such as Panax ginseng (Yan et al, 2019) and Panax notoginseng (Jin et al, 2017;Han et al, 2020).…”

One of the most remarkable natural plants is Vaccaria hispanica (Mill.) Rauschert, which has a high economic, medicinal and industrial potential due to its valuable compounds. However, it is mostly an underused plant worldwide. To implement doubled haploid technology in plant breeding programs and exploit its potential, first knowing the particulars of the species is necessary. This study was aimed to explore the androgenic potential of different wild Turkish V. hispanica genotypes collected from different Turkish regions, as a starting point to identify bottlenecks to solve in future studies. As to induction of microspore embryogenesis, nearly all of them responded, with efficiencies reaching 300 embryos/100 buds in some cases. However, we also found three main bottlenecks. First, the presence of foam-producing saponins in flowers prevented an efficient isolation of microspores. Second, embryos showed a reduced ability to germinate. Third, a dense network of hairy roots prevented the formation of a true, fully functional root system. Together, these drawbacks led to the production of very few DH plants. The presence of rhizogenic endophytes may be the cause of most of these problems, which opens the door for possible solutions.
