Published: March 27, 2023

Amid climate change, heatwave events are expected to increase in frequency and severity. As a result, yield losses viticulture due stress have increased over the years. one of most important crops world, an eco-friendly mitigation strategy is greatly needed. The present work aims evaluate physiological fitness improvement by two marine plant growth-promoting rhizobacteria consortia Vitis vinifera cv. Antão Vaz under conditions. To assess potential biophysical biochemical thermal feedback amelioration, photochemical traits, pigment fatty acid profiles, osmotic oxidative biomarkers were analysed. Bioaugmented grapevines exposed presented significantly enhanced photoprotection capability higher thermo-stability, exhibiting lower dissipation energy flux than non-inoculated plants. Additionally, rhizobacterial tested improved light-harvesting capabilities increasing reaction centre availability preserving photosynthetic efficiency. Rhizobacteria inoculation expressed osmoprotectant promotion, revealed osmolyte concentration while maintaining leaf turgidity. Improved antioxidant mechanisms membrane stability resulted lowered lipid peroxidation product formation when compared Although found differ their effectiveness, these findings demonstrate that bioaugmentation induced significant tolerance mitigation. This study promising usage PGPR promote minimize impacts grapevines.

In the European Union and worldwide there are a burgeoning markets for plant growth promoting microorganisms (PGPM) other biological agents as soil improvers, bio-fertilizers, bio-stimulants, control or bio-pesticides. Microbial have major share in this development. The use of such products is often advertised with promise contributing to sustainable agricultural practices by increasing crop yield offering an alternative substitute decrease dependency agriculture on hazardeous agrochemicals. contrast registered microbial protection products, PGPM that marketed EU improvers biostimulants, not strictly required proven minimum efficacy levels under field conditions. Manufacturers only ensure these do pose unacceptable risks human, animal health, safety environment. Uniform guidelines comparable EPPO - standards (European Mediterranean Plant Protection Organisation) test trials available. This paper attempts fill gap.

Plant-microbe interactions in the rhizosphere for smarter and more sustainable crop fertilization: the case of PGPR-based biofertilizers

Frontiers in Microbiology, Journal Year: 2024, Volume and Issue: 15

Published: Aug. 8, 2024

Biofertilizers based on plant growth promoting rhizobacteria (PGPR) are nowadays gaining increasingly attention as a modern tool for more sustainable agriculture due to their ability in ameliorating root nutrient acquisition. For many years, most research was focused the screening and characterization of PGPR functioning nitrogen (N) or phosphorus (P) biofertilizers. However, with increasing demand food using far fewer chemical inputs, new investigations have been carried out explore potential use such bacteria also potassium (K), sulfur (S), zinc (Zn), iron (Fe) In this review, we update biofertilizers smarter crop production deliberate prospects microbiome engineering-based methods tools shed light improvement mineral nutrition.

Synthetic Hydrogel Dilutes Serratia plymuthica Growth— Promoting Effect on Brassica napus L. Under Drought Conditions

Agriculture, Journal Year: 2025, Volume and Issue: 15(2), P. 142 - 142

Published: Jan. 10, 2025

Progressive climate change increases drought frequency, severely impacting crop growth and yield. New eco-friendly alternatives to chemical protection agents fertilisers are needed reduce pollution enhance plant health. This study evaluated the effects of growth-promoting rhizobacteria (PGPR) hydrogel (potassium polyacrylate) on Brassica napus L. during conditions. After in vitro pot experiments, Serratia plymuthica was selected from six PGPR candidates based its ability biomass, shoot length, number internodes. The seed viability test, reactive oxygen species accumulation, SOD activity showed no adverse applying canola seeds. Moreover, did not show toxicity towards tested bacterial strains. Field trials demonstrated that inoculation with S. significantly increased siliques (16.48%) yield (19.93%), compared controls. Plants grown inoculated seeds were also taller (3.28%) had more branches (39.99%). We analysed seedling emergence, internodes, thousand seeds’ weight, moisture. applied soil delayed emergence dampened effect plymuthica, resulting reduced Compared plants there a decrease treated solely bacterium 23.61% 27.79%, respectively. Our results indicate has high potential for use commercial farming, especially as an ingredient added coatings.
