Salinity stress poses a severe risk to food security and crop productivity. Stress reduction techniques are not necessarily sustainable or environmentally friendly. With the increasing adverse impact of salinity area, it is necessary restore ameliorate using friendly approaches. In this context, beneficial rhizospheric microbes may offer approach managing stress. We used Bacillus subtilis strain Z-12 B. aryabhattai Z-48 improve growth turnip (Brassica rapa subsp. rapa) plants under conditions elucidated these bacterial strains on different physiological biochemical aspects plants. The application both had significant (p < 0.05) positive influence analyzed parameters salt Here, superiorly increased shoot length (33.2-, 25.8%), root (38.6-, 31.5%), fresh biomass (23.9-, 17.8%), dry (38.60-, 48.6%) in normal saline (200 mM NaCl) conditions, respectively. Physiological studies showed that antioxidant enzyme activities were significantly by stress, with few exceptions. Moreover, inoculation effectively total chlorophyll, soluble sugar, phenolic, flavonoid, glucosinolate contents simulated conditions. Hence, findings support framework inoculating can enhance their tolerance against

B. cereus is an important plant growth promoting bacteria. It provides sustainable ways to increase yield as well protection from environmental stress such heavy metals. can both nutrition and act osmoprotection agent. This study investigated seed priming of into T. aestivum seeds under arsenic cadmium stress. Growth parameters, gas exchange, photosynthesis efficiency, antioxidant capacity were measured. As and/or Cd application caused 32%, 18% 24% decrease in the relative rate (RGR) As, Cd, combined (As+Cd) groups, respectively. High amounts reduction photosynthetic parameters detected on applications recovery these increased proline accumulation. The increases Fv/Fm Fv/Fo indicated that system efficiency PSII reaction center recovered. ROS accumulation aestivum. By recovered with activity SOD by 42.8% As+B group 11.80% Cd+B group. With bacteria other enzymes also showed boosted therefore reducing H2O2 content preventing peroxidation. Bacteria AsA-GSH cycle stresses. Therefore, highly effective against metal availability metals and, increasing for plants.

Feasibility of Nano-Urea and PGPR on Salt Stress Amelioration in Reshmi Amaranth (Amaranthus tricolor): Stress Markers and Enzymatic Response

Horticulturae, Год журнала: 2025, Номер 11(3), С. 280 - 280

Опубликована: Март 5, 2025

The present experiment aimed to examine the impact of nano urea (NU) and plant growth-promoting rhizobacteria (PGPR) on Reshmi amaranth (Amaranthus tricolor) growth under salt stress. Experiments were conducted using six different combinations NaCl, NU, PGPR for 35 days greenhouse conditions. results showed that salinity stress significantly (p < 0.05) reduced parameters, including shoot height, root length, fresh weight, leaf area. However, application NU PGPR, both individually in combination, enhanced physiological resilience saline + treatment yielded best improvements, with a height 42.25 cm, length 34.79 weight 61.69 g, indicating synergistic effect. Biochemical analysis NaCl lowered chlorophyll (0.25 mg/g fwt.) carotenoids (60.17 µg/100 g) disrupted ionic homeostasis by increasing Na⁺ accumulation while reducing K+ Ca2+ uptake. combined restored balance, 58.12 mg K⁺ levels 115.25 78.70 mg, respectively. Stress markers such as malondialdehyde (MDA) proline also significant reductions, antioxidant enzyme activities stabilized application. Thus, this study indicated mitigate salt-induced improving nutrient assimilation, promoting osmotic regulation, enhancing antioxidative defenses amaranth.

Plant Host Provenances Affect Taxonomic Composition of Root-Associated Culturable Bacteria from Tripterygium wilfordii Hook f. and Their Plant Growth Promoting Properties

Forests, Год журнала: 2025, Номер 16(4), С. 637 - 637

Опубликована: Апрель 6, 2025

Plant-associated microbes play a crucial role in host growth, health, and stress resistance. Host plants significantly influence the assembly of their microbial communities. To examine plant provenance on bacterial composition growth promoting (PGP) properties, we compared readily culturable bacteria isolated from root interior rhizosphere Tripterygium wilfordii Hook f., woody Chinese medicinal plant, across three provenances grown different regions. Regardless growing environment, abundance endophytic colonies followed trend: Fujian > Hunan Hubei provenances. A total 227 isolates were classified into 21 genera 40 rhizosphere, with Pseudomonas and/or Bacillus as dominant genera. The taxonomic varied environments. Plants same but cultivated locations exhibited greater similarity composition. majority assayed strains displayed one or more PGP traits. Local harbored higher proportion than non-local plants. Our findings indicate that influences root-associated bacteria, particularly native environments may recruit to enhance fitness.
