Verticillium stripe, caused by longisporum, is an emerging disease of canola (Brassica napus) in Canada. Studies were conducted to assess the impact pH on both growth V. longisporum and its virulence host. Fungal was assessed measuring colony diameter following 14 21 days incubation potato dextrose agar at varying levels (4.7, 5.5, 6.5, 7.4, or 8.6). The results indicated that colonies approximately 16% greater 7.4 8.6 compared with those 5.5. development seedling stage investigated using a semi-hydroponic system different 4.4, 5.4, 6.3, 7.5, 8.4 half-strength Hoagland’s solution. stripe most severe 7.5 after 10-day period system. In second inoculation experiment, seedlings previously inoculated fungus transplanted into potting mix amended four (5.6, 6.4, 7.2, 7.8). transplants cultivated under greenhouse conditions evaluated for severity plant maturity. Disease greatest 7.8. This first study effects canola. It suggests substantial risk increased yield losses due regions neutral slightly alkaline soils.

Clubroot (Plasmodiophora brassicae) is an important soilborne disease that causes severe damage to cruciferous crops in China. This study aims compare the differences chemical properties and microbiomes between healthy clubroot-diseased soils. To reveal difference, we measured soil microbial communities by sequencing 18S 16S rRNA amplicons. The available potassium diseased soils was higher than fungal diversity significantly Ascomycota Proteobacteria were most dominant phylum bacteria all samples, respectively. Plant-beneficial microorganisms, such as Chaetomium Sphingomonas, more abundant Co-occurrence network analysis found networks complex stable link number, density, clustering coefficient of those networks. Our results indicate community structure different from great significance exploring biological control strategies clubroot disease.

Background and aims Clubroot caused by the soilborne obligate parasite Plasmodiophora brassicae , is a devastating disease of Chinese cabbage other crucifers. The innate diversity adaptability this pathogen pose significant challenges to effective control measures. However, varied response mechanisms exhibited hosts pathotype 11 at molecular level are still unclear. Methods results This study investigated resistance underlying mechanism two ( Brassica rapa ) varieties (JP 83-1) P. through comparative transcriptome analysis microscopic study. Results demonstrated that 14 days after inoculation (dai) critical time point infection process for resistant variety inhibit proliferation brassica . Although highly JP did not exhibit complete immune 11, it against restricting its in xylem vessels. Microscopic 21 dai revealed cultivar (JP) root structure remained largely unaffected, while roots susceptible (83-1) tissue distortion gall formation, underscoring effectiveness mechanisms. Comparative substantial differences number types differentially expressed genes (DEGs) between cultivars, highlighting key pathways involved response. In (JP), total 9,433 DEGs were identified, with 4,211 up-regulated 5,222 down-regulated. contrast, 6,456 DEGs, 2,781 3,675 showed pronounced activation hormone signaling, cell wall, secondary metabolism, redox state, signaling process. Therefore, our speculation revolves around potential variety, which inhibits via metabolites, ROS also regulates physiological mediated plant hormones such as ABA adapt adverse environmental conditions water scarcity induced pathogen. Conclusion unveils intricate defense potentially activated within when confronted offering valuable insights breeding programs development novel strategies managing clubroot crops. Furthermore, highlights pivotal role host-specific underlie 11.

Despite the identification of clubroot resistance genes in various Brassica crops our understanding genetic basis immunity to Plasmodiophora brassicae infection model plant Arabidopsis thaliana remains limited. To address this issue, we performed a screen 142 natural accessions and identified 11 clubroot-resistant lines. Genome-wide association analysis several loci significantly linked with resistance. Three from two these were targeted for deletion by CRISPR/Cas9 mutation resistant Est-1 Uod-1. Deletion Resistance 1 (RPB1) rendered both lines susceptible P. pathotype P1+. Further rpb1 knock-out Uod-1 showed that RPB1 protein is required activation downstream defence responses, such as expression phytoalexin biosynthesis gene CYP71A13. has recently been shown encode cation channel localised endoplasmic reticulum. The accession Col-0 lacks functional gene; when transformed driven its native promoter it capable activating transcription response infection, but not sufficient confer Transient Nicotiana tabacum induced programmed cell death leaves.

Clubroot disease is a soil-borne caused by Plasmodiophora brassicae. It occurs in cruciferous crops exclusively, and causes serious damage to the economic value of worldwide. Although different measures have been taken prevent spread clubroot disease, most fundamental effective way explore use disease-resistance genes breed resistant varieties. However, resistance level plant hosts influenced both environment pathogen race. In this work, we described terms discovery current distribution, life cycle, race identification systems; particular, summarized recent progress on control methods breeding practices for cultivars. With knowledge these identified loci R genes, discussed feasible strategies future.

Clubroot, a soil-infective disease caused by Plasmodiophora brassicae, is serious affecting cruciferous plants around the world. There no effective control measure to completely remove this pathogen from fields after infection. Here, we screened and identified two strains (Hz36, Trichoderma guizhouense; Hk37, koningiopsis) of gall clubroot in rapeseed with biocontrol potential for clubroot. The fermentation broth Hz36 could significantly inhibit germination resting spores P. promote seed root growth rapeseed. efficiency strain on Arabidopsis thaliana was 44.29% 52.18%, respectively. qPCR results revealed that treatment reduce content brassicae cells, paraffin section analysis it delay development brassicae. Strain Hk37 showed similar effects Hz36, whose reach 57.30% 68.01% A. thaliana. These indicate have

Abstract The commercial aspect of growing Brassica crops has always been influenced by the worldwide occurrence clubroot pathogen, Plasmodiophora brassicae . Clubroot symptoms reduce crop yield dramatically and resilient protist is hard to eradicate from infested soils. Chemical treatments are not so efficient their use allowed only in a few areas world, none them EU. majority control mediated using resistant crops, but all species have good or durable resistance sources available, these can be overcome evolving new pathotypes. Some commercially available biocontrol agents tested found on such as rapeseed, cauliflower Chinese cabbage some extent. More organisms isolated described recent decades for many application still long way off. In this review we summarize trends bacterial fungal endophytes well mechanisms behind effects reported, antibiosis, defense induction competition space nutrients. There indeed plenty studies reached point where ready applied at field scale. potential endophytic microbes pest management against disease huge.

ABSTRACT Clubroot, caused by the biotrophic protist Plasmodiophora brassicae , is a devastating root disease that affects all members of Brassicaceae family. Significant progress has been made in understanding its occurrence, life cycle and management strategies. This posed considerable threat to producers breeders globally, including South Asia. The reported India, Nepal parts Bangladesh, Bhutan, Pakistan Sri Lanka. cool moist climatic conditions northern Himalayan belt, combined with acidic soils inadequate systems, are key factors, particularly areas India prone clubroot outbreaks. Disease strategies currently focus on soil amendments, use synthetic fungicides fumigants application resistant genotypes. However, limited research conducted modes transmission. Recent studies revealed contaminated infected seedlings major contributors spread pathogen. Brassica crops such as B. juncea (mustard), napus (canola) oleracea (cabbage) vulnerable. cultivars like ‘Midas’ ‘Big Sun 111’, ‘Nepa Star’ ‘Kathmandu Local’, have identified Nepal, offering some potential for mitigating disease. To combat effectively, there an urgent need integrated development genetic materials. These efforts should involve diverse stakeholders, producers, industries, government sectors academicians, aiming advance challenges bridging critical
