“…Global demand for protein-rich food sources including legumes for human food and animal feed will continue rising (Foyer et al, 2016). Intensification of food production to meet the rising food demand is associated with depletion of soil fertility (Kopittke et al, 2019), which results in the misuse of fertilizers and pesticides (Warra and Prasad, 2020), that serves the unsustainable goal of eliminating competition from pests and pathogens (Karoney et al, 2020), while trying to attain dominance in food markets (Gonzalez, 1999;Chalam et al, 2020). The result of such unsustainable practices is increased costs of production (Adolph et al, 2020), amidst a resource depleted and polluted agroecosystem that is toxic to human health and biodiversity (Mahmud et al, 2020;Warra and Prasad, 2020).…”

Rhizobia are bacteria that exhibit both endophytic and free-living lifestyles. Endophytic rhizobial strains are widely known to infect leguminous host plants, while some do infect non-legumes. Infection of leguminous roots often results in the formation of root nodules. Associations between rhizobia and host plants may result in beneficial or non-beneficial effects. Such effects are linked to various biochemical changes that have far-reaching implications on relationships between host plants and the dependent multitrophic biodiversity. This paper explores relationships that exist between rhizobia and various plant species. Emphasis is on nutritional and phytochemical changes that occur in rhizobial host plants, and how such changes affect diverse consumers at different trophic levels. The purpose of this paper is to bring into context various aspects of such interactions that could improve knowledge on the application of rhizobia in different fields. The relevance of rhizobia in sustainable food systems is addressed in context.

“…Like any crop, sun ower can be affected by pathogens (e.g., bacteria, and fungi) that survive in seeds and use them as a pathway of dissemination (Addrah et al, 2020;Chalam et al, 2020). Fungi can reduce seed quality and seed longevity, thus impacting germination and plant establishment in the eld (Srinivas et al, 2017).…”

Fusarium spp. are among the most common fungal species associated with diseases both on wild and cultivated plants, including sunflowers. They infect all plant tissues causing damage to roots, bundle vessels, stems, leaves, and seeds, often causing significant yield losses. Because contaminated seeds can spread diseases into new areas and transmit them to growing plants, the quality and sanitary status of the seeds are the key to limit the spread of the disease. This study aimed to identify and determine the prevalence of Fusarium species associated with sunflower seeds and access their transmission to growing plants. A set of 49 Fusarium isolates was collected from seeds of eight sunflower cultivars. They were characterized through morphological, cultural, and genetic features. Genetic diversity was estimated through amplification of the elongation factor gene (EF-1 α), which also served to select representative isolates to perform amplification of the β-tubulin 2 gene (TUB2). There were identified four species of Fusarium (i.e., F. fabacearum, F. proliferatum, F. pseudocircinatum and F. verticillioides) that caused seed rot, vascular darkening, withering, malformation, and stunting of growing sunflower plants. Among them, F. proliferatum was the most prevalent species. Our results highlight that various species of Fusarium are associated with damage on sunflower seeds and all of them can be transmitted through infected seeds and cause disease in growing plants.

“…Contamination of seeds or bulbs with some groups of pathogenic microorganisms, such as fungi and bacteria, can limit germination and cause diseases in young seedlings, leading to a significant reduction in plant performance ( Chang et al, 2020 , Gitaitis and Ronald, 2007 ). Transmission of seed-borne pathogens during the local and international exchange or trade leads to the introduction of new strains of pathogens that are absent previously, which may subsequently result in the emergence of epidemics ( Elmer, 2001 , Gergerich et al, 2015 , Chalam et al, 2020 ). Furthermore, some seed-borne fungi such as Fusarium sp.…”
