Climate-Resilient Microbial Biotechnology: A Perspective on Sustainable Agriculture

Abstract

We designed this review to describe a compilation of studies to enlighten the concepts of plant–microbe interactions, adopted protocols in smart crop farming, and biodiversity to reaffirm sustainable agriculture. The ever-increasing use of agrochemicals to boost crop production has created health hazards to humans and the environment. Microbes can bring up the hidden strength of plants, augmenting disease resistance and yield, hereafter, crops could be grown without chemicals by harnessing microbes that live in/on plants and soil. This review summarizes an understanding of the functions and importance of indigenous microbial communities; host–microbial and microbial–microbial interactions; simplified experimentally controlled synthetic flora used to perform targeted operations; maintaining the molecular mechanisms; and microbial agent application technology. It also analyzes existing problems and forecasts prospects. The real advancement of microbiome engineering requires a large number of cycles to obtain the necessary ecological principles, precise manipulation of the microbiome, and predictable results. To advance this approach, interdisciplinary collaboration in the areas of experimentation, computation, automation, and applications is required. The road to microbiome engineering seems to be long; however, research and biotechnology provide a promising approach for proceeding with microbial engineering and address persistent social and environmental issues.

Unleashing the Potential of Bacterial Isolates from Apple Tree Rhizosphere for Biocontrol of Monilinia laxa: A Promising Approach for Combatting Brown Rot Disease

“…Accordingly, our isolates, namely, AP5 ( S. marcescens ), AP13 ( B. cereus ), and AP4 ( P. baetica ), represent potential biocontrol candidates, exhibiting the highest antagonistic activity against M. laxa mycelial growth. Genera such as Agrobacterium , Arthrobacter , Bacillus , Cellulomonas , Enterobacter , Pseudomonas , and Serratia are known for their biocontrol potential against plant diseases [ 50 ]. Rachid et al [ 51 ] reported the ability of B. amyloliquefaciens B10W10 and Pseudomonas sp.…”

Potential of Plant Growth Promoting Rhizobacteria on Growth of Potato (Solanum tuberosum L) under Field Condition

“…Most rhizospheric soil of vegetable root contains high number of beneficial bacterial strains due to the root exudates which chemically compose of one or more of growth factors such as carbohydrates, amino acid, vitamins and organic acid which are necessary for bacterial maintenance and growth [3,6]. On other hand, free living nitrogen fixing strains of Azotobacter spp and Azospirillum spp promote the growth of plants by providing fixed nitrogen to the plants.…”

“…All PGPR can affect IOP Publishing doi:10.1088/1755-1315/1213/1/012039 2 plant growth directly. Direct effects through the synthesis of phytohormones, vitamins, inhibition of plant ethylene synthesis, enhanced stress resistance and improved nutrient uptake, solubilization of inorganic phosphate and mineralization of organic phosphate; while, diazotrophs and siderophores are able to decrease or prevent the deleterious effects of pathogenic microorganisms as indirect effects of applying PGPR [5,6]. The application of biofertilizer with PGPR becomes the main potential way to decrease negative environmental impacts resulting from the extensive chemical fertilizers.…”

Cytokinin deficiency confers enhanced tolerance to mild, but decreased tolerance to severe salinity stress in in vitro grown potato

“…A major point of concern for the world’s sustainable development is food security, due to the rapid increase in global human population on the one hand, and extensive land degradation and climate change on the other ( Liu et al., 2020 ; Tan et al., 2022 ; Teo et al., 2022 ). Potato ( Solanum tuberosum L.) is the world’s fourth most important food crop, after maize, wheat, and rice.…”
