Current Insights into the Role of Rhizosphere Bacteria in Disease Suppressive Soils

Frontiers in Microbiology, Journal Year: 2017, Volume and Issue: 8

Published: Dec. 18, 2017

Disease suppressive soils offer effective protection to plants against infection by soil-borne pathogens, including fungi, oomycetes, bacteria and nematodes. The specific disease suppression that operates in these is, most cases, microbial origin. Therefore, are considered as a rich resource for the discovery of beneficial microorganisms with novel antimicrobial other plant protective traits. To date, several genera have been proposed key players suppressiveness soils, but complexity interactions well underlying mechanisms traits remain elusive soils. Recent developments next generation sequencing 'omics technologies provided new insights into ecology identification consortia involved suppressiveness. Here, we review results recent 'omics-based studies on basis emphasis role rhizosphere this intriguing microbiological phenomenon.

Fusarium oxysporum f. sp. lycopersici causal agent of vascular wilt disease of tomato: Biology to diversity– A review

Saudi Journal of Biological Sciences, Journal Year: 2019, Volume and Issue: 26(7), P. 1315 - 1324

Published: June 4, 2019

Tomato (Lycopersicon esculentum) is one of the widely grown vegetables worldwide. Fusarium oxysporum f. sp. lycopersici (FOL) significant contributory pathogen tomato vascular wilt. The initial symptoms disease appear in lower leaves gradually, trail by wilting plants. It has been reported that FOL penetrates plant, colonizing and leaving tissue dark brown, this discoloration extends to apex, leading plants wilting, collapsing dying. Therefore, it accepted caused fungus result a combination various physiological activities, including accumulation fungal mycelia around xylem, mycotoxin production, inactivation host defense, production tyloses; however, are variable. selection molecular markers may be more effective means screening races. Several studies on detection have carried out suggested potency technique for diagnosing FOL. This review focuses biology variability FOL, understanding presenting holistic picture wilt relation model, biology, virulence. We conclude genomic proteomic approachesare greater tools identification informative candidates involved pathogenicity, which can considered as approaches managing disease.

Rhizosphere protists are key determinants of plant health

Microbiome, Journal Year: 2020, Volume and Issue: 8(1)

Published: March 3, 2020

Abstract Background Plant health is intimately influenced by the rhizosphere microbiome, a complex assembly of organisms that changes markedly across plant growth. However, most microbiome research has focused on fractions this particularly bacteria and fungi. It remains unknown how other microbial components, especially key predators—protists—are linked to health. Here, we investigated holistic including bacteria, eukaryotes (fungi protists), as well functional metabolism genes. We these communities genes throughout growth tomato plants either developed disease symptoms or remained healthy under field conditions. Results found pathogen dynamics best predicted protists. More specifically, microbial-feeding phagotrophic protists differed between later diseased at establishment. The relative abundance phagotrophs negatively correlated with growth, suggesting predator-prey interactions influence performance. Furthermore, likely shifted bacterial functioning enhancing pathogen-suppressing secondary metabolite involved in mitigating success. Conclusions illustrate importance top-down controllers propose perspective, protists, provides optimal next step predicting
