Grapevine rootstock and soil microbiome interactions: Keys for a resilient viticulture. HORTICULTURE RESEARCH 2022; 9:uhac019. [PMID: 35184168 PMCID: PMC8985100 DOI: 10.1093/hr/uhac019] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Revised: 12/18/2021] [Accepted: 01/17/2022] [Indexed: 05/10/2023]
Abstract
Soil microbiota has increasingly been shown to play an integral role in viticulture resilience. The emergence of new metagenomic and culturomic technologies has led to significant advances in the study of microbial biodiversity. In the agricultural sector, soil and plant microbiomes have been found to significantly improve resistance to environmental stressors and diseases, as well as influencing crop yields and fruit quality thus improving sustainability under shifting environments. Grapevines are usually cultivated as a scion grafted on rootstocks, which are selected according to pedoclimatic conditions and cultural practices, known as terroir. The rootstock connects the surrounding soil to the vine's aerial part and impacts scion growth and berry quality. Understanding rootstock and soil microbiome dynamics is a relevant and important field of study, which may be critical to improve viticulture sustainability and resilience. This review aims to highlight the relationship between grapevine roots and telluric microbiota diversity and activity. In addition, this review explores the concept of core microbiome regarding potential applications of soil microbiome engineering with the goal of enhancing grapevine adaptation to biotic and abiotic stress.

Surfactin Stimulated by Pectin Molecular Patterns and Root Exudates Acts as a Key Driver of the Bacillus-Plant Mutualistic Interaction. mBio 2021; 12:e0177421.

Abstract
Bacillus velezensis is considered as a model species belonging to the so-called Bacillus subtilis complex that evolved typically to dwell in the soil rhizosphere niche and establish an intimate association with plant roots. This bacterium provides protection to its natural host against diseases and represents one of the most promising biocontrol agents. However, the molecular basis of the cross talk that this bacterium establishes with its natural host has been poorly investigated. We show here that these plant-associated bacteria have evolved a polymer-sensing system to perceive their host and that, in response, they increase the production of the surfactin-type lipopeptide. Furthermore, we demonstrate that surfactin synthesis is favored upon growth on root exudates and that this lipopeptide is a key component used by the bacterium to optimize biofilm formation, motility, and early root colonization. In this specific nutritional context, the bacterium also modulates qualitatively the pattern of surfactin homologues coproduced in planta and forms mainly variants that are the most active at triggering plant immunity. Surfactin represents a shared good as it reinforces the defensive capacity of the host. IMPORTANCE Within the plant-associated microbiome, some bacterial species are of particular interest due to the disease protective effect they provide via direct pathogen suppression and/or stimulation of host immunity. While these biocontrol mechanisms are quite well characterized, we still poorly understand the molecular basis of the cross talk these beneficial bacteria initiate with their host. Here, we show that the model species Bacillus velezensis stimulates the production of the surfactin lipopeptide upon sensing pectin as a cell surface molecular pattern and upon feeding on root exudates. Surfactin favors bacterial rhizosphere fitness on one hand and primes the plant immune system on the other hand. Our data therefore illustrate how both partners use this multifunctional compound as a unique shared good to sustain a mutualistic interaction.

Abstract
During the past years, microorganisms have been the cause of many problems for human's health. However, today with the development of many techniques of microbiology, the researchers have studied several roles of microorganisms which may help the society. Microbial-based products are expected to play important role in agriculture-enhancing plant production and therefore increasing crop's yieldeswani et al. . Microorganisms can act by several action mechanisms including antibiosis or mechanisms in plant-microbe interactions underlining the dual function of microbial strains toward plant nutrition and protection. The market has increased with the development of microbial-based products. Currently, it is normal to think that microorganisms help us in agriculture by applying them as biological control. In this mini review, we collect the last findings about this topic including very recent literature. KEY POINTS: • Microorganisms play a beneficial role in agriculture by different mechanisms. • One of these mechanisms is the secretion of chemical compounds with different activities.

Abstract
With edible insects being increasingly produced, food safety authorities have called for the determination of microbiological challenges posed to human health. Here, we find that the bacterial endospore fraction in industrially reared mealworm and cricket samples is largely comprised of Bacillus cereus group members that can pose insect or human health risks. Hepatitis A virus, hepatitis E virus and norovirus genogroup II were not detected in the sample collection, indicating a low food safety risk from these viral pathogens.

Abstract
The metabolites of Bacillus subtilis CCIBP-M27 were evaluated as an antagonist of Pseudocercospora fijiensis. The culture filtrate did not inhibit ascospore germination but significantly reduced conidial germination and mycelial growth. Through microscopic analysis, deformations were observed as vacuolization and swelling in P. fijiensis mycelia when exposed to culture filtrate during 48 h. A similar response was induced by peptide-type compounds found on Bacillus subtilis CCIBP-M27 culture filtrate. The results obtained suggest that the in vitro antifungal effect of the strain CCIBP-M27 against P. fijiensis is related to the action of diffused metabolites such as proteins or peptide substances.

Abstract
Grapevine is one of the most widely grown fruit crops in the world. At present, however, there is much concern regarding chemical pollution in viticulture due to the application of chemical fungicides and fertilizers. One viticultural practice to resolve this issue is the application of micro-organisms to grapevine as a substitute for chemicals. Some micro-organisms act as an enhancer of grape berry quality as well as a suppresser of disease in grapevine through their antagonistic ability and/or systemic resistance inducing ability. Herein, we review current and prospective applications of micro-organisms in viticulture. SIGNIFICANCE AND IMPACT OF THE STUDY In this review, we evaluate the applicability of micro-organisms in viticulture. Micro-organisms can improve grape berry quality through grapevine disease protection and grape berry quality alteration. Because the use of micro-organisms to protect grapevine from plant diseases is safer than the use of chemical fungicides, the use of biofungicides in viticulture is expected to be enhanced by the increasing consumer concern towards chemical fungicides. Micro-organisms also modify plant secondary metabolites for use as flavours, pharmaceuticals and food additives. Studies of micro-organisms that promote polyphenol, anthocyanin and aroma compound biosynthesis are in progress with an eye to improving grape berry quality.
