“…Other comparative studies have also shown that consortium inoculation may be better than a single inoculation with PGPRs. Rice plants ( Oryza sativa L.), one of the most important crops for the human population worldwide [ 96 ], were inoculated with a group of plant growth-promoting Bacillus strains (( Bacillus licheniformis (A21), B. haynesii (EN43), B. paralicheniformis (EN107), B. licheniformis (EN108), B. paralicheniformis (EN121), and B. haynesii (EN124)) and showed a higher biomass accumulation and increased grain yield [ 97 ]. Similarly, the synergistic action of two plant growth-stimulating bacteria, Pseudomonas putida and Bacillus amyloliquefaciens , was observed by the increasing tolerance to drought stress in Cicer arietinum L. Importantly, growth parameters such as root and shoot length and dry weights of roots and shoots were significantly higher in plants inoculated with the consortium than in the individual PGPR interaction [ 98 ].…”

The growing human population has a greater demand for food; however, the care and preservation of nature as well as its resources must be considered when fulfilling this demand. An alternative employed in recent decades is the use and application of microbial inoculants, either individually or in consortium. The transplantation of rhizospheric microbiomes (rhizobiome) recently emerged as an additional proposal to protect crops from pathogens. In this review, rhizobiome transplantation was analyzed as an ecological alternative for increasing plant protection and crop production. The differences between single-strain/species inoculation and dual or consortium application were compared. Furthermore, the feasibility of the transplantation of other associated micro-communities, including phyllosphere and endosphere microbiomes, were evaluated. The current and future challenges surrounding rhizobiome transplantation were additionally discussed. In conclusion, rhizobiome transplantation emerges as an attractive alternative that goes beyond single/group inoculation of microbial agents; however, there is still a long way ahead before it can be applied in large-scale agriculture.

“…Rice ( Oryza sativa L ) is a fundamental staple crop for humanity, and it has a profound influence on the survival and progress of human society ( Cao et al., 2018 ). The cultivation of rice holds significant importance as a staple food crop for over three billion individuals globally ( Azizi and Lau, 2022 ). Approximately 90% of the world’s rice is produced in Asia and China is one of the largest global rice producers ( Samal et al., 2022 ).…”

IntroductionRice (Oryza sativa L.) is a pivotal cereal crop worldwide. It relies heavily on the presence of iron plaque on its root surfaces for optimal growth and enhanced stress resistance across diverse environmental conditions.MethodTo study the crystallographic aspects of iron plaque formation on rice roots, the concentrations of Fe2+ and PO43- were controlled in this study. The effects of these treatments were assessed through comprehensive analyzes encompassing root growth status, root surface iron concentration, root vitality, enzyme activities, and microstructural characteristics using advanced techniques such as root analysis, scanning electron microscopy (SEM), and ultrathin section transmission electron microscopy (TEM).ResultsThe results demonstrated that an increase in the Fe2+ concentration or a decrease in the PO43- concentration in the nutrient solution led to improvements in various root growth indicators. There was an elevation in the DCB (dithionite-citrate–bicarbonate) iron content within the roots, enhanced root vitality, and a significant increase in the activities of the superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) enzymes. Moreover, as the Fe2+ concentration increased, amorphous iron oxide minerals on the root surface were gradually transformed into ferrihydrite particles with sizes of approximately 200 nm and goethite particles with sizes of approximately 5 μm. This study showed that an increase in the Fe2+ concentration and a decrease in the PO43- concentration led to the formation of substantial iron plaque on the root surfaces. It is noteworthy that there was a distinct gap ranging from 0.5 to 3 μm between the iron plaque formed through PO43- treatment and the cellular layer of the root surface.DiscussionThis study elucidated the impacts of Fe2+ and PO43- treatments on the formation, structure, and morphology of the iron plaque while discerning variations in the spatial proximity between the iron plaque and root surface under different treatment conditions.

“…More than 50 kinds of rice fungal diseases, 6 kinds of bacterial diseases, 11 kinds of viral and mycoplasmosis, and 4 kinds of nematode diseases have been found in China [1][2][3]. The common diseases mainly include rice blast, sheath blight, white leaf blight, flax spot, rice stalk, rice grain smut and bad seedling [4][5][6].…”

“…(1) Lighter weight and smaller sizes need to be adopted to make the spore collection device smaller and more lightweight [24][25][26][27]. (2) The existing fixed spore capture equipment can obtain spores in glass slides, Eisenhoff bottles, scotch tape or bottle containers (as shown in Table 1), and the design of sample carriers also has room for research [28,29]. (3) We improve the work efficiency of mobile spore collection device by enhancing the ability of a single device that supports multiple sample collection tasks [21,30].…”

Fungal spores that cause infectious fungal diseases in rice are mainly transmitted through air. The existing fixed, portable or vehicle-mounted fungal spore collection devices used for rice infectious diseases have several disadvantages, such as low efficiency, large volume, low precision and incomplete information. In this study, a mobile fungal spore collection device is designed, consisting of six filters called “Capture-A”, which can collect spores and other airborne particles onto a filter located on a rotating disc of six filters that can be rotated to a position allowing for the capture of six individual samples. They are captured one at a time and designed and validated by capturing spores above the rice field, and the parameters of the key components of the collector are optimized through fluid simulation and verification experiments. The parameter combination of the “Capturer-A” in the best working state is as follows: sampling vessel filter screen with aperture size of 0.150 mm, bent air duct with inner diameter of 20 mm, negative pressure fan with 1500 Pa and spore sampling of cylindrical shape. In the field test, the self-developed “Capturer-A” was compared with the existing “YFBZ3” (mobile spore collection device made by Yunfei Co., Ltd., Zhengzhou, China). The two devices were experimented on at 15 sampling points in three diseased rice fields, and the samples were examined and counted under a microscope in the laboratory. It was found that the spores of rice blast disease and rice flax spot disease of rice were contained in the samples; the number of samples collected by a single sampling vessel of “Capturer-A” was about twice that of the device “YFBZ3”in the test.
