Enhancing wheat resilience to salinity: the role of endophytic Penicillium chrysogenum as a biological agent for improved crop performance

BMC Plant Biology, Journal Year: 2025, Volume and Issue: 25(1)

Published: March 19, 2025

Salinity stress severely impacts wheat productivity, necessitating effective strategies to enhance crop resilience. This study investigates the potential of Penicillium chrysogenum CM022 as a biological agent alleviate impact salinity on (Triticum aestivum L.). P. improved germination seeds, particularly under 150 mM NaCl. Fungal inoculation significantly plant growth in terms root length, height, and seedling biomass, even high conditions. Notably, inoculated plants preserved photosynthetic pigments reduced oxidative damage, evidenced by lower levels hydrogen peroxide (H₂O₂) malondialdehyde (MDA), compared non-inoculated controls. The also exhibited enhanced proline soluble sugar contents, which are crucial for osmotic adjustment stress. Additionally, increased antioxidant capacity wheat, boosting total phenolic flavonoid enhancing enzyme activity salinity. These findings underscore improving tolerance through physiological, biochemical, defense mechanisms, supporting its use sustainable agricultural practices mitigate adverse effects production.

Enhancing Pea Plant Growth, Nutrient Acquisition, and Symbiosis in Cobalt‐Stressed Soil Using Metal‐Tolerant Klebsiella sp.

Journal of Basic Microbiology, Journal Year: 2025, Volume and Issue: unknown

Published: March 28, 2025

ABSTRACT Excessive cobalt (Co) levels in agricultural soil cause significant toxicity, reducing crop growth and yield. This study aimed to assess the potential of Klebsiella sp. SRB‐5 (Accession no. OR715782), mitigating toxicity enhancing garden peas under stress. Strain SRB‐5, tolerant 4000 ppm Co(II), was evaluated for producing growth‐regulating substances, including indole‐3‐acetic acid (IAA), ammonia, siderophore, ACC deaminase, solubilized phosphate, The optimal conditions Co‐(II) biosorption by were determined be 25°C, pH 6.0, an incubation time 72 h. strain's ability mitigate tested inoculating grown treated with 1000, 2000, 3000 Co‐(II). Inoculation Co‐tolerant alleviated significantly enhanced physiological biochemical properties plants. Notably, increased root length (19.2%), biomass (29%), seedling vigor index (18.4%), total chlorophyll (52%), nodule (41%), leghaemoglobin content (38%), nitrogen (27%), phosphorous (19.3%) 1000 Co‐stressed peas. Additionally, bacterial inoculation reduced proline, malondialdehyde (MDA), hydrogen peroxide (H 2 O ), membrane injury 85%, 57.3%, 90%, 75%, respectively, Co‐exposed Priming also uptake roots (88%), shoots (53.7%), grains (79.6%) compared uninoculated treatments. Metal‐tolerant beneficial bacteria, such as strain could serve effective alternative pea production metal‐contaminated soils. use PGPR strains holds development biofertilizers future practices.

Synergistic relationship of endophyte-nanomaterials to alleviate abiotic stress in plants

Frontiers in Environmental Science, Journal Year: 2022, Volume and Issue: 10

Published: Nov. 24, 2022

Plant responses to abiotic stresses through diverse mechanisms and strategic measures in utilizing nanomaterials have positively impacted crop productivity. Stress can cause membrane depletion, reactive oxygen species formation, cell toxicity death, reduction plant growth. However, mitigate some of the negative impacts enhance yield. Some endophytic microbes synthesize nanomaterials, which maintain health growth via nitrogen fixation, siderophore production, phytohormones synthesis, enzyme production without any pathological effects. Nanoparticle-synthesizing endophytes also help boost biochemical physiological functions by ameliorating impact stresses. The increase use implementation nano-growth enhancers from beneficial microbes, such as nano-biofertilizers, nano-pesticides, nano-herbicides, nano-fungicides are considered safe eco-friendly ensuring sustainable agriculture agrochemical usage. Promisingly, nanotechnology concepts aim sustain protect plants oxidative activation anti-oxidative enzymes. relieve stress still require further discussion literature. Therefore, this review is focused on induction tolerance plants,
