“…ese results indicated the high impact of rice rhizosphere microorganisms on the 2AP level in KDML 105 rice grains. It was reported that several bacterial genera such as Bacillus, Acinetobacter, Pseudomonas, and Enterobacter increased the 2AP level of aromatic rice by 1.14-1.42-fold [52]. erefore, it could be concluded from this study that the higher microbial population in the ORF system might be one of the key factors in enhancing 2AP synthesis in the rice grains.…”

Khao Dawk Mali 105 (KDML105) is a premium fragrant rice variety and is widely grown in Thung Kula Rong Hai (TKR), northeast Thailand. In the present study, the influence of organic and conventional rice farming (ORF and CRF, respectively) in TKR farmers’ paddy fields on soil properties and their relationship with 2-acetyl-1-pyrroline (2AP) in KDML105 rice grains were investigated. The results indicated that the ORF system had a strong positive effect on major soil quality indicators and the 2AP content in the rice grains. The soil organic matter (SOM) was approximately twice as much in the ORF than in the CRF system, thus leading to much higher total nitrogen (TN), humic acid (HA), and microbial populations in the ORF system. The higher SOM in the ORF system not only enhanced the soil quality indicators but also contributed to approximately 3.5 times higher 2AP than in the CRF system. Principle component analysis indicated a close correlation among SOM, TN, HA, and microbial population under the ORF system; these variables exhibited strong correlations with the 2AP contents in KDML105 rice grains.

“…PGPR are either exogenous bacteria introduced into agricultural ecosystems or autochthonous bacteria that are being enhanced. Both types of bacteria act positively upon plant development in annual and perennial crops and under different abiotic conditions [18,19]. The genera of PGPR that are most often used in sustainable agriculture are Azospirillum, Azotobacter, Bacillus, Enterobacter, Pseudomonas, and Rhizobium [20,21].…”

Effects of Bacillus subtilis and Pseudomonas fluorescens Inoculation on Attributes of the Lettuce (Lactuca sativa L.) Soil Rhizosphere Microbial Community: The Role of the Management System

Inoculation with beneficial microbes has been proposed as an effective practice for the improvement of plant growth and soil health. Since soil acts as a physicochemical background for soil microbial communities, we hypothesized that its management will mediate the effects of microbial inoculants on the indigenous soil microbes. We examined the effects of bacterial inoculants [Bacillus subtilis (Ba), Pseudomonas fluorescens (Ps), and both (BaPs)] on the growth of Lactuca sativa cultivated in soils that originated from an organic maize (OS) and a conventional barley (CS) management system. Moreover, the biomass and the community structure of the rhizosphere microbial communities and the soil enzyme activities were recorded. The root weight was higher in CS than OS, while the foliage length was greater in OS than CS treatments. Only in OS pots, inoculants resulted in higher biomasses of bacteria, fungi, and actinomycetes compared to the control with the highest values being recorded in Ps and BaPs treated soils. Furthermore, different inoculants resulted in different communities in terms of structure mainly in OS soils. For soil enzymes, the effect of the management system was more important due to the high organic matter existing in OS soils. We suggest that for microbial inoculation to be effective it should be considered together with the management history of the soil.

“…PGPR have been shown to increase productivity in a variety of different crops (e.g., tomato, lettuce, wheat, soybean, rice and apples) under normal and stressful conditions (Deshmukh et al, 2016;Etesami and Alikhani, 2016;Bhattacharyya and Jha, 2012).…”

Rhizosphere engineering: Enhancing sustainable plant ecosystem productivity

The rhizosphere is arguably the most complex microbial habitat on earth, comprising an integrated network of plant roots, soil and a diverse microbial consortium of bacteria, archaea, viruses, and microeukaryotes. Understanding, predicting and controlling the structure and function of the rhizosphere will allow us to harness plantmicrobe interactions and other rhizosphere activities as a means to increase or restore plant ecosystem productivity, improve plant responses to a wide range of environmental perturbations, and mitigate effects of climate change by designing ecosystems for longterm soil carbon storage. Here, we review critical knowledge gaps in rhizosphere 2 science, and how mechanistic understanding of rhizosphere interactions can be leveraged in rhizosphere engineering efforts with the goal of maintaining sustainable plant ecosystem services for food and bioenergy production in an ever changing global climate.
