“…Wheat seedlings inoculated with a Paenibacillus ehimensis strain from Lonicera japonica showed marked increases in growth associated with greater photosynthetic carbon uptake and light use efficiency (Zhao et al, 2015). Furthermore, multiple other benefits on the growth of plants that are attributed to endophytes include modification of root morphology, osmotic adjustment, phosphate siderophore production improvement, solubilization activity enhancement, and stomatal regulation (Compant et al, 2005;Chen et al, 2016;Zhu, 2019). These plant growthpromotive bacterial endophytes are presently used for forest regeneration and contaminated soil phytoremediation (Ryan et al, 2008;Huang et al, 2020).…”

Plants benefit extensively from endophytic bacteria, which live in host plant tissues exerting no harmful effects. Bacterial endophytes promote the growth of host plants and enhance their resistance toward various pathogens and environmental stresses. They can also regulate the synthesis of secondary metabolites with significant medicinal properties and produce various biological effects. This review summarizes recent studies on the relationships between bacterial endophytes and medicinal plants. Endophytic bacteria have numerous applications in agriculture, medicine, and other industries: improving plant growth, promoting resistance toward both biotic and abiotic stresses, and producing metabolites with medicinal potential. Their distribution and population structure are affected by their host plant’s genetic characteristics and health and by the ecology of the surrounding environment. Understanding bacterial endophytes can help us use them more effectively and apply them to medicinal plants to improve yield and quality.

“…Steady tissue hydration enhances drought tolerance in plants. Zhu (2019) reported that bacterial endophytes improve the process of imbibition increasing RWC significantly that helps the host plant to tolerate osmotic stress. In addition, increasing LDMC in the treatment plants show that the endophyte played a greater role in increasing the dry mass of the leaf and the maximum water retained since, LDMC largely depends on these two factors ( Garnier et al., 2001 ).…”

Conventional agricultural practices demand application of pesticides for better yield, yet their uncontrolled use for longer duration exhibit deleterious effects on the soil health and subsequent plant productivity. These circumstances have displayed alarming effects on food security in the modern world. Therefore, biological solutions to the crisis can be practiced in consideration to their environmental benefits. Bacterial endophytes are ubiquitous in the phytosystem and beneficial for the plant growth and productivity. The present study aimed to obtain endophytic bacterial strains that can be developed as effective plant growth promoters. For this purpose twelve strains of bacterial endophytes were isolated from different plant sources and their putative plant growth promoting attributes were analyzed by morphological and biochemical studies. Subsequently these isolates were inoculated in the Solanum lycopersicum (Tomato) and the factors like germination percentage, seedling length, biomass production, and leaf variables were analyzed. However, the vigour index was considered as the prime parameter for determining plant growth. In essence, RR2 and RR4 strains were observed as effective growth promoter, hence in future they can be utilized as effective biofertilizers.

“…Ammodendron bifolium is a desert deciduous shrub of the genus Ammodendron in the Fabaceae family and is a preferred tree species for wind prevention and sand fixation [39]. A. bifolium is only distributed in China in the Takelmohuur Desert in Huocheng County, Ili, Xinjiang, and is endangered [40]. The microbial community present in the roots of A. bifolium, as a legume, significantly contributes to its adaptation in the unique desert environment.…”

Drought has become a serious environmental problem affecting people all around the world as a result of rising atmospheric pollution and global warming. Through symbiosis with Arbuscular mycorrhizal fungus (AMF), plants may mitigate the impacts of drought stress on growth and development as well as physiological metabolism. As a pioneer plant for windbreak and sand fixation, the symbiosis between AMF and Ammodendron bifolium can improve its drought resistance, which is of great significance for species protection and desertification control. In this study, A. bifolium seedlings were used as the test subject in a pot experiment with four drought stress gradients and two inoculation treatments to examine the effects of water treatment and AMF inoculation on the growth of the seedlings. The results showed that drought stress significantly inhibited the growth indexes of A. bifolium seedlings such as the height, basal diameter, blades number, and biomass, and that inoculation with AMF could promote the growth of A. bifolium seedlings and help mitigate the damage caused by drought stress. Drought stress increased the antioxidant enzyme activity and proline (Pro) accumulation in A. bifolium plants, and AMF inoculation induced higher antioxidant enzyme activity and lower malondialdehyde (MDA) and Pro contents in A. bifolium seedlings compared to non-AMF-inoculated plants. Drought stress harmed the chloroplast structure, reduced the chlorophyll concentration, and decreased the photosynthetic efficiency in A. bifolium seedlings. The ability of AMF-inoculated plants to withstand drought was enhanced by increased levels of photosynthetic pigments, higher photosynthetic activity, and increased photosynthetic product accumulation in the roots. These results suggest that AMF inoculation can alleviate drought-induced damage by promoting plant growth and improving plant antioxidant, osmoregulation, and photosynthetic capacity. In the context of increasing drought due to global warming, AMF inoculation can be an excellent way to enhance A. bifolium drought resistance.
