Microorganisms, Год журнала: 2023, Номер 11(4), С. 1088 - 1088

Опубликована: Апрель 21, 2023

Rhizosheric bacteria with several abilities related to plant growth and health have been denominated Plant Growth-Promoting Rhizobacteria (PGPR). PGPR promote through modes of action, be it directly or indirectly. The benefits provided by these can include increased nutrient availability, phytohormone production, shoot root development, protection against phytopathogens, reduced diseases. Additionally, help plants withstand abiotic stresses such as salinity drought produce enzymes that detoxify from heavy metals. become an important strategy in sustainable agriculture due the possibility reducing synthetic fertilizers pesticides, promoting health, enhancing soil quality. There are many studies literature. However, this review highlights used for production a practical way, making possible reduce use phosphorus nitrogen fungicides, improve uptake. This addresses topics unconventional fertilizers, seed microbiome rhizospheric colonization, microorganisms, fixation chemical solubilizing mineralizing, siderophore fungicides pesticides agriculture.

Plant Growth Promoting Actinobacteria, the Most Promising Candidates as Bioinoculants?

Frontiers in Agronomy, Год журнала: 2022, Номер 4

Опубликована: Март 21, 2022

Plant Growth Promoting Bacteria (PGPBs) are a strong ally for sustainable agriculture. They offer an interesting alternative to chemical fertilizers and pesticides. Many microorganisms have been widely documented their PGPR traits, but actinobacterial microbes which increasingly only these two past decades ability promote plant growth. Their action on health yield could be either direct, indirect or both. This review will cover articles that published Actinobacteria PGP highlighting the involved mechanisms reveal potential as microbial fertilizers. Possible strategies encourage use bioinoculants also discussed.

Fungi That Promote Plant Growth in the Rhizosphere Boost Crop Growth

Journal of Fungi, Год журнала: 2023, Номер 9(2), С. 239 - 239

Опубликована: Фев. 10, 2023

The fungi species dwelling in the rhizosphere of crop plants, revealing functions that endeavor sustainability are commonly referred to as ‘plant-growth-promoting fungi’ (PGPF). They biotic inducers provide benefits and carry out important agricultural sustainability. problem encountered system nowadays is how meet population demand based on yield protection without putting environment human animal health at risk production. PGPF including Trichoderma spp., Gliocladium virens, Penicillium digitatum, Aspergillus flavus, Actinomucor elegans, Podospora bulbillosa, Arbuscular mycorrhizal fungi, etc., have proven their ecofriendly nature ameliorate production crops by improving growth shoots roots germination seeds, chlorophyll for photosynthesis, abundant crops. PGPF’s potential mode action follows: mineralization major minor elements required support plants’ productivity. In addition, produce phytohormones, induced resistance, defense-related enzymes inhibit or eradicate invasion pathogenic microbes, other words, help plants while encountering stress. This review portrays an effective bioagent facilitate promote production, plant growth, resistance disease invasion, various abiotic stresses.

Rhizobia: A Promising Source of Plant Growth-Promoting Molecules and Their Non-Legume Interactions: Examining Applications and Mechanisms

Agriculture, Год журнала: 2023, Номер 13(7), С. 1279 - 1279

Опубликована: Июнь 21, 2023

For over a century, the scientific community has had comprehensive understanding of how rhizobia can promote growth legumes by forming nitrogen fixing nodules. Despite this knowledge, interaction with non-legumes remained largely ignored as subject study until more recent decades. In last few years, research shown that also associate non-legume roots, which ultimately leads to stimulation through diverse direct and indirect mechanisms. example, enhance phytohormones production, improvement plant nutrient uptake, such solubilization precipitated phosphorus, production siderophores address iron needs, reduction ethylene levels ACC deaminase enzyme cope drought stress. Additionally, improve, indirectly, biocontrol pathogens induction systemic resistance in host plant. It increase root adherence soil releasing exopolysaccharides, regulate water movement. The objective review is assess analyze existing knowledge information regarding mechanisms non-legumes. By conducting analysis these findings, we aim gain new insights into development Rhizobium/non-legume interactions.

Actinobacteria as a source of biofertilizer/biocontrol agents for bio-organic agriculture

Journal of Applied Microbiology, Год журнала: 2022, Номер 134(2)

Опубликована: Дек. 16, 2022

Abstract The global human population keeps growing and natural energy supplies are depleting, creating a threat to environmental demands, food security, supply. As result, increased agricultural output is required accomplish the rising population's demands. A strong reliance on chemical fertilizers boost production has harmed environment health, it becoming too expensive as well. One of potential solution this problem use beneficial microorganisms substitute for artificial in production. Actinobacteria have been used most successful long-lasting throughout evolution. They thought be one primordial living forms our planet. Actinobacteria, particularly Streptomyces, proved their ability formulate biofertilizers sector by supplying nutrients plants better growth, increasing yield, managing abiotic biotic stress, resisting phytopathogen assault. This review describes mechanism actinobacterial current market challenges future importance sustainable agriculture.

Crop germplasm: Current challenges, physiological-molecular perspective, and advance strategies towards development of climate-resilient crops

Heliyon, Год журнала: 2023, Номер 9(1), С. e12973 - e12973

Опубликована: Янв. 1, 2023

Germplasm is a long-term resource management mission and investment for civilization. An estimated ∼7.4 million accessions are held in 1750 plant germplasm centres around the world; yet, only 2% of these assets have been utilized as genetic resources (PGRs). According to recent studies, current food yield trajectory will be insufficient feed world's population 2050. Additionally, possible negative effects terms crop failure because climate change already being experienced across world. Therefore, it necessary reconciliation research advancement innovation practices further exploration potential especially complex traits associated with such water- nitrogen use efficiency. In this review, we tried address challenges, gaps, physiological molecular aspects two broad spectrum nitrogen-use efficiency, advanced integrated strategies that could provide platform combined stress climate-smart development. development technologies directly related characterization was highlighted utilization towards elite varieties.
