Autoria: NISHISAKA, C. S.; VENTURA, J. P.; QUEVEDO, H. D.; GODOY, F. de A.; ROSSMANN, M.; MENDES, R. Conteúdo: Abstract: In this study, we have identified and characterized three genomes from bacteria isolated from the rhizosphere of Triticum aestivum. Streptomyces virginiae CMAA1738 and Paenibacillus ottowii CMAA1739 were obtained from the wheat landrace Iran 1-29-11334, and Pseudomonas inefficax CMAA1741 was isolated from the wheat landrace Karakilcik. 2024-01-01T00:00:00Z https://www.alice.cnptia.embrapa.br/alice/handle/doc/1156276 Título: Diversity of viruses and viroids in the rhizosphere of common bean cultivars differing in resistance to the fungal root pathogen Fusarium oxysporum. Autoria: BRAGA, L. P.; TANENTZAP, A. J.; LEE, B.; TSAI, S. M.; RAAIJMAKERS, J. M.; MENDES, R.; MENDES, L. W. Conteúdo: Abstract: The rhizosphere microbiome plays a key role in plant protection against soil-borne pathogens. Plant breeding for resistance against soil-borne pathogens can alter the rhizosphere microbiome. However, most studies have focused on bacterial and fungal communities, leaving the role of the virus and viroids unassessed. Here, we tested the influence of resistance breeding on the composition of rhizosphere viruses and viroids. By analyzing metatranscriptomes from the rhizosphere of common bean (Phaseolus vulgaris) cultivars with varying resistance to the soil-borne pathogen Fusarium oxysporum, we recovered sequences representing 78 and 23 novel populations of viruses and viroids, respectively. We compared the abundances of these infectious agents across the different cultivars and found that the Fusarium-resistant cultivar harbored >1.2 times more viroids and a more different composition of viroids and viruses than less resistant plants. Given their role in interfering with host metabolism and their potential influence on plant-fungi associations, our study suggests that changes in the rhizosphere infectome are an important consideration in breeding for resistance against soil-borne pathogens. 2023-01-01T00:00:00Z https://www.alice.cnptia.embrapa.br/alice/handle/doc/1128958 Título: First report of Geotrichum candidum causing sour-rot of melon in Brazil. Autoria: HALFELD-VIEIRA, B. de A.; TERAO, D.; NECHET, K. de L. Conteúdo: This is the first report of G. candidum on melon in Brazil. Sour-rot is a well-known disease of melon in other countries (Ceponis 1966) and can be listed as a potential postharvest disease for melon fruit in Brazil. 2020-01-01T00:00:00Z https://www.alice.cnptia.embrapa.br/alice/handle/doc/1114805 Título: Genome sequence of Streptomyces cavourensis 1AS2a, a rhizobacterium isolated from the brazilian Cerrado biome. Autoria: VARGAS HOYOS, H. A.; SANTOS, S. N.; PADILLA, G.; MELO, I. S. de Conteúdo: Abstract: Streptomyces cavourensis strain 1AS2a, isolated from wheat rhizosphere in the Brazilian Neotropical savanna, exhibits strong antimicrobial activities. Its genome comprises 7,600,475 bp with 6,590 open reading frames (ORFs) that reveal 30 biosynthetic gene clusters (BGCs). It provides a genetic basis for further research of the potential of this strain for the production of antimicrobial compounds. 2019-01-01T00:00:00Z
