The disease is prevalent post-rainy season when high moisture and warm temperatures prevail. Severe defoliation is observed during favourable environments, leading to a significant loss in productivity. Based on the importance of the pathogen agriculturally, the P. abelmoschi isolate Cer 86 - 18 (MCC:9491) was selected for genome sequencing. The genome assembly of P. abelmoschi resulted in a genome of 31.90 Mb with an overall GC content of 54.26%. Quantitative genome assessment using BUSCO (Benchmarking Universal Single-Copy Orthologs) identified 1,664 (97.53%) complete BUSCOs, reflecting a high representation of conserved genes with minimal duplication and strong orthologous uniqueness. Gene prediction analysis identified 11,325 protein-coding genes, of which 3,857 were annotated using the KEGG database. As per analyses, 410 genes were predicted to encode carbohydrate-active enzymes, whereas 369 genes were predicted to encode peptidases. Eighteen gene clusters involved in secondary metabolite biosynthesis were also identified. A total of 143 proteins were predicted to be effectors using the in-silico pipeline. This is the first report on the genome organisation of P. abelmoschi. This study was designed to address this gap by enhancing our understanding of the genome organisation of P. abelmoschi and gene annotation, thereby paving the way for functional genomics studies, such as identifying virulence genes to aid in resistance breeding. Also, this genome could be another addition to the available genomic resources of the genus Pseudocercospora and can provide valuable insights into host-pathogen interactions and evolutionary relationships.</p>","PeriodicalId":23703,"journal":{"name":"World journal of microbiology & biotechnology","volume":"41 5","pages":"174"},"PeriodicalIF":4.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144080794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we investigated the role of the WhiB-like (Wbl) family transcriptional regulator, WhiD_sbh, in modulating SM production in Streptomyces bingchenggensis BC04. Overexpression of whiD_sbh in BC04 significantly suppressed milbemycin production by repressing the transcription of the milbemycin biosynthetic gene cluster via the ActK/R-KelR regulatory cascade. Comparative transcriptomic analysis between the whiD_sbh overexpression strain and BC04 revealed that whiD_sbh overexpression not only altered the expression of multiple other biosynthetic gene clusters but also impacted genes involved in central carbon metabolism, glutathione biosynthesis, and cofactor synthesis. Furthermore, cross-species genetic analysis demonstrated that whiD_sbh overexpression enhanced actinorhodin production in Streptomyces coelicolor and avermectin production in Streptomyces avermitilis, while inhibiting the biosynthesis of nemadectin and guvermectin in Streptomyces cyaneogriseus ssp. noncyanogenus and Streptomyces caniferus, respectively.

The physical-chemical parameters of the adsorbent used, notably moisture, ash, organic matter, pH and elemental analysis were determined. Next-generation sequencing and scanning electron microscopy analyses were carried out to detect and identify the nature of bacterial communities in the biofilters used. The results of the chemical analysis showed that the adsorbent used is appropriate for the development of the microorganisms. X-ray fluorescence analysis showed that the adsorbent belongs to the silico-aluminous materials, proving its effectiveness as an adsorbent. The efficiency of ammonia removal was over 93% using the biofilter. Next-generation sequencing revealed that bacteria belonging to ammonia oxidizers such as Nitrosomonas and Nitrosospira are among the most abundant bacteria after the biofiltration process, which explains the efficiency of ammonia removal.

Advanced characterization using HPTLC, FTIR, and HR-LCMS revealed the presence of amino acids, peptides, and fatty acid amides, further validating its structural complexity. Antimicrobial assays demonstrated superior efficacy of COBS, exhibiting significant antibacterial activity against Chromobacterium violaceum (24 mm) and Acinetobacter calcoaceticus (22 mm), alongside pronounced antifungal effects against Candida albicans, Fusarium proliferatum, and Penicillium purpurogenum.

The current study aimed to characterize the Pst pathotype distribution in North India. A total of 61 stripe rust infected samples were collected from sub-mountainous areas of Punjab (50), Himachal Pradesh (HP) (8) and Jammu & Kashmir (J&K) (3) during 2021-24. Virulence profiling results of 58 samples using Indian stripe rust differentials revealed the prevalence of five pathotypes (238S119, 110S119, 46S119, 47S103 and 6S0) in North India. Among which 238S119 was the most predominant (51.72%) one followed by 110S119 (27.59%) and 46S119 (17.24%). No virulence was found against stripe rust resistant Yr5, Yr10, Yr15, Yr24 and YrSP genes indicating these genes are the most effective resistant genes in North India providing complete resistance till date.
