Exploring microbiomes for plant disease management

Olive leaf spot caused by Venturia oleaginea: An updated review

“…Indeed, the microbiome science is revealing the importance of complex network of interactions between microorganisms within each ecological niche, suggesting that a single microbial isolate might not be sufficient to contrast the development of plant pathogens. In this context, synthetic microbial communities (SynComs) defined as small consortia of microorganisms designed to mimic, at some scale, the observed function and structure of the microbiome in natural conditions might be the key to develop the next generation of effective and sustainable management strategies ( Malacrinò et al., 2022b ).…”

Plant genotype influence the structure of cereal seed fungal microbiome

“…When further digging into the variation of the seed microbiome between different cultivars, we found that the structure of fungal communities associated with different varieties of T. aestivum and T. turgidum were shaped by plant genotype. A genotype-driven effect on plant microbiome has been previously shown for several plant species (Wagner et al 2016; Brown et al 2020; F. Liu et al 2019; Malacrinò, Mosca, et al 2022; Wassermann et al 2022), but also among wheat varieties (Kavamura et al 2021). Indeed, previous research found that wheat genotype can shape the diversity and structure of microbial communities in bulk soil (Yergeau, Quiza, and Tremblay 2020), rhizosphere (Donn et al 2015; Mahoney, Yin, and Hulbert 2017; Azarbad et al 2020; Kavamura et al 2020; Rossmann et al 2020; Simonin et al 2020; Wolińska, Kuźniar, and Gałązka 2020), roots (Azarbad et al 2020; Cui et al 2022), and leaves (Azarbad et al 2020; Sapkota, Jørgensen, and Nicolaisen 2017; Žiarovská et al 2020).…”

“…Second, we tested whether different cultivars within the species T. aestivum and T. turgidum would associate with different fungal communities. According to previous research on wheat (Donn et al 2015; Azarbad et al 2020; Yergeau, Quiza, and Tremblay 2020) and other plant species (Wagner et al 2016; Brown et al 2020; F. Liu et al 2019; Malacrinò, Mosca, et al 2022), we hypothesize to detect a strong genotype-depend signal on the structure of fungal communities within each group.…”

“…Plant-associated microbial communities are well known for their impact on the ecology and evolution of their host (Trivedi et al 2020; Malacrinò, Abdelfattah, et al 2022). The structure of plant microbiomes largely differentiate within the same plant (e.g., between roots, leaves, fruits, flowers, seeds), and within the same compartment (e.g., different tissues within the same organ) (Trivedi et al 2020; Dastogeer et al 2020; Abdelfattah et al 2016), and it is influenced by several factors, including soil (Zarraonaindia et al 2015; Malacrinò, Karley, et al 2021), herbivores (Malacrinò, Karley, et al 2021; French, Kaplan, and Enders 2021; Malacrinò, Wang, et al 2021; Frew 2022), pathogens (Ginnan et al 2020; Wen et al 2020; Ewing et al 2021), and abiotic stresses (Vescio et al 2021; Yu et al 2022).…”

“…Plants, to a certain extent, are able to direct the assembly of their own microbiome. Indeed, plant genotype has been proven to influence, with different strengths, the structure of microbial communities associated with different plant species, including Boechera stricta (Wagner et al 2016), Medicago trunculata (Brown et al 2020), Glycine max (F. Liu et al 2019), Olea europaea (Malacrinò, Mosca, et al 2022), and several others. This effect is thought to occur through changes in the plant metabolome (e.g., exudates, VOCs), and it can be modulated by plants to help coping with biotic and abiotic stresses (H. Liu et al 2020).…”
