The application of plant growth-promoting rhizobacteria in Solanum lycopersicum production in the agricultural system: a review

Abstract

Food safety is a significant challenge worldwide, from plantation to cultivation, especially for perishable products such as tomatoes. New eco-friendly strategies are needed, and beneficial microorganisms might be a sustainable solution. This study demonstrates bacteria activity in the tomato plant rhizosphere. Further, it investigates the rhizobacteria’s structure, function, and diversity in soil. Rhizobacteria that promote the growth and development of tomato plants are referred to as plant growth-promoting bacteria (PGPR). They form a series of associations with plants and other organisms in the soil through a mutualistic relationship where both parties benefit from living together. It implies the antagonistic activities of the rhizobacteria to deter pathogens from invading tomato plants through their roots. Some PGPR are regarded as biological control agents that hinder the development of spoilage organisms and can act as an alternative for agricultural chemicals that may be detrimental to the health of humans, animals, and some of the beneficial microbes in the rhizosphere soil. These bacteria also help tomato plants acquire essential nutrients like potassium (K), magnesium (Mg), phosphorus (P), and nitrogen (N). Some rhizobacteria may offer a solution to low tomato production and help tackle food insecurity and farming problems. In this review, an overview of soil-inhabiting rhizobacteria focused on improving the sustainable production of Solanum lycopersicum.

Drought-induced recruitment of specific root-associated bacteria enhances adaptation of alfalfa to drought stress

“…However, there is still a large knowledge gap about the potential functions of alfalfa rhizosphere microbes in improving its resistance, which has been explored in other plants (Zhao et al, 2020). For example, different core communities of rhizosphere microbiomes constructed from unique varieties of plants such as tomato (Adedayo et al, 2022), citrus (Penyalver et al, 2022), and wheat (Azarbad et al, 2018) were able to improve their environmental adaptability. Similarly, genetically diverse rice varieties respond to drought stress by using specific rhizosphere microbial communities (Santos-Medellin et al, 2017).…”

Fungi That Promote Plant Growth in the Rhizosphere Boost Crop Growth

“…Phytohormones perform an important function in controlling the growth of crop plants and their defense mechanisms [ 23 ]. IAA is a prominent auxin hormone that promotes the growth of crop plants’ shoots and roots.…”

“…PGPF perform the following functions in plants: antagonistic or biocontrol potential by competing for space and nutrients [ 10 ], growth hormone production [ 21 ], mineral solubilization, mycoparasitic and saprophytic resistance, root colonization, and induced systemic resistance (ISR) in plants [ 22 ]. Aside from the above roles mentioned, PGPF suppress the invasion of phytopathogens on tomato plants as well as other crop plants, they contribute to the improvement of nutrients in the soil, and they produce 1-aminocyclopropane-1-carboxylate (ACC) deaminase and other phytohormones to reduce the production of ethylene in the plants [ 23 ].…”

The Role of Endophytic Microorganisms in Increasing Plant Resistance Under Salt Stress

“…Систематический и углубленный обзор текущего состояния эндофитного бактериального разнообразия, стратегии колонизации ими растений и их благотворного воздействия на устойчивое сельское хозяйство за счет сокращения и/или отказа от использования токсичных агрохимикатов, а также в качестве защитных агентов против болезней растений и для повышения урожайности сельскохозяйственных культур представлен в обзоре Morales-Cedeño с соавторами [31]. Показано, что бактерии с атрибутами PGP являются ключевыми компонентами почвы, способными устанавливать полезные ассоциации с растениями [32]. Их наиболее изученные представители описаны в работах Yadav с соавторами [33] и Kour с соавторами [34].…”
