Modification of Rhizosphere Microbial Communities: A Possible Mechanism of Plant Growth Promoting Rhizobacteria Enhancing Plant Growth and Fitness

Frontiers in Plant Science, Journal Year: 2022, Volume and Issue: 13

Published: May 26, 2022

Plant beneficial bacteria, defined as plant growth-promoting rhizobacteria (PGPR), play a crucial role in plants’ growth, stress tolerance and disease prevention. In association with the rhizosphere of plants, PGPR facilitate growth development either directly or indirectly through multiple mechanisms, including increasing available mineral nutrients, moderating phytohormone levels acting biocontrol agents phytopathogens. It is generally accepted that effectiveness inoculants associated their ability to colonize, survive persist, well complex network interactions rhizosphere. Despite promising promotion results commonly reported mostly attributed phytohormones other organic compounds produced by inoculants, little information on potential mechanisms underlying such positive effects via modifying microbial community soil functionality. this review, we overviewed ecology function, hypothesizing may promote health composition functioning community, highlighting further directions for investigating from an ecological perspective.

Constraints and Prospects of Improving Cowpea Productivity to Ensure Food, Nutritional Security and Environmental Sustainability

Frontiers in Plant Science, Journal Year: 2021, Volume and Issue: 12

Published: Oct. 22, 2021

Providing safe and secure food for an increasing number of people globally is challenging. Coping with such a human population by merely applying the conventional agricultural production system has not proved to be agro-ecologically friendly; nor it sustainable. Cowpea ( Vigna unguiculata (L) Walp) multi-purpose legume. It consists high-quality protein consumption, rich in livestock fodder. enriches soil that recycles nutrients through fixation nitrogen association nodulating bacteria. However, productivity this multi-functional, indigenous legume great value African smallholder farmers rural populace, also urban consumers entrepreneurs, limited. Because cowpea strategic importance Africa, there need improve on its productivity. Such endeavors Africa are wrought challenges include drought, salinity, excessive demand among synthetic chemicals, repercussions climate change, declining nutrients, microbial infestations, pest issues, so forth. Nevertheless, giant strides have already been made improvements adopting sustainable smart biotechnological approaches favorably influencing costs availability. As such, prospects leap enhancement genetic gain good. Potential viable means overcoming some above-mentioned constraints would focus key producer nations encourage them embrace techniques integrated approach enhance This review highlights spectrum limit yield, but looks ahead seeks way forward Africa. More importantly, investigates applications insights concerning mechanisms action implementing eco-friendly techniques, as deployment bio inoculants, climate-smart (CSA) practices, conservation multi-omics technology spheres genomics, transcriptomics, proteomics, metabolomics, improving yields achieve agro-ecosystems, ensuring their stability.

Effects of Two Bacillus Velezensis Microbial Inoculants on the Growth and Rhizosphere Soil Environment of Prunus davidiana

International Journal of Molecular Sciences, Journal Year: 2022, Volume and Issue: 23(21), P. 13639 - 13639

Published: Nov. 7, 2022

Microbial inoculants, as harmless, efficient, and environmentally friendly plant growth promoters soil conditioners, are attracting increasing attention. In this study, the effects of Bacillus velezensis YH-18 B. YH-20 on Prunus davidiana rhizosphere bacterial community in continuously cropped were investigated by inoculation tests. The results showed that a pot seedling experiment, with resulted certain degree increase diameter growth, height, leaf area at different time periods 180 days compared control. Moreover, after 30 90 inoculation, available nutrients effectively improved, which protected from acidification. addition, high-throughput sequencing microbial inoculants slowed decrease richness diversity over one-month period. At phylum level, Proteobacteria Bacteroidetes significantly enriched 30th day. genus Sphingomonas Pseudomonas 15 days, respectively. These phyla genera can improve nutrient utilization rate, antagonize pathogenic bacteria, benefit plants. Furthermore, similar changes microbiome. This study provides basis for short-term effect P. microbiome has application value promoting cultivation production high-quality fruit trees.

Ginseng root rot caused by Fusarium solani (F. solani) is a highly destructive soil-borne disease that happens worldwide, which seriously affects the growth and development of many types crops. Frankia casuarinae CcI3 (Frankia F1) microbial inoculants F1 on mycelial integrity pathogenic fungus F. solani, ginseng plants, structure rhizosphere community were carefully studied in soil infected with disease. Under normal environment, plant height, length, dry weight, stem diameter, leaf area, chlorophyll content increased 40.57%, 68.98%, 92.09%, 56.67%, 23.29%, 39.60% T2 (50 mL compared CK (natural control without treatment). Increased enzyme activity phenylalanine ammonia-lyase (PAL), peroxidase (POD), polyphenol oxidase (PPO), β-1, 3-glucanase, chitinase showed improved resistance stress plants leaves having inoculation. Our present study demonstrated pH value, cation exchange capacity, organic matter, total nitrogen, available phosphorus, potassium 8.00%, 50.78%, 18.81%, 43.36%, 23.25%, 14.00%, 5.11% CK. Furthermore, activities catalase, sucrase, urease treatment 12.14%, 27.56%, 22.60%, respectively. Amplicon sequencing analysis revealed diversity bacteria decreased after treatment. More specifically, inhibited promoted relative abundance Xanthomonadales, Sphingomonadales, Sphingobacteriales, Frankiales, Propionibacteriales. The PICRUSt data predicted an array bacterial functions, primarily functional genes related to metabolism we confirmed. Collectively, found optimal inoculation amount for inhibiting promoting was 50 (T2), could effectively regulate during production. It helped promote sustainable Chinese agriculture.
