Multivesicular bodies (MVBs) play essential roles in many cellular processes. The MVB pathway requires reversible membrane association of the endosomal sorting complexes required for transports (ESCRTs) sustained protein trafficking. Membrane dissociation ESCRTs is catalyzed by AAA ATPase SKD1, which stimulated LYST-INTERACTING PROTEIN 5 (LIP5). We report here that LIP5 a target pathogen-responsive mitogen-activated kinases (MPKs) and plays critical role plant basal resistance. Arabidopsis...

Streptomyces species 1–14 isolated from cassava rhizosphere soil were evaluated for their antibacterial efficacy against Fusarium oxysporum f.sp. cubense race 4 (FOC4). Of the 63 strains tested, thirteen exhibited potent properties and further screened eight fungal pathogens. The strain that showed maximum inhibition all of test pathogens was identified by 16S rDNA sequencing as sp. 1–14, selected studies. Through propagation in under simulated conditions, we found FOC4 did not significantly...

Plant roots are usually colonized by various arbuscular mycorrhizal (AM) fungal species, which vary in morphological, physiological, and genetic traits. This colonization constitutes the nutrient uptake pathway (MP) supplements through roots. Simultaneously, extraradical hyphae of each AM fungus is associated with a community bacteria. However, whether structure function microbiome on differ between species remains unknown. In order to understand predicted functions different split-root...

Endophytic bacteria-based biocontrol is regarded as a potential plant disease management strategy. Present study analyzed the diversity of mulberry endophytic bacteria basing on culture-dependent approach and further evaluated their antimicrobial growth-promoting (PGP) activities. A total 608 cultivable bacteria, belonging to 4 phyla 36 genera, were isolated from four cultivars having different resistance sclerotiniosis in three seasons. Taxonomic compositional analysis results showed that...

Thaumatin-like proteins (TLPs), which are defined as pathogenesis-related protein family 5 (PR5) members, common plant involved in defense responses and confer antifungal activity against many pathogens. Our earlier studies have reported that the TaTLP1 gene was isolated from wheat proved to be response leaf rust attack. The present study aims identify interacting of characterize role interaction between Puccinia triticina (Pt). Pull-down experiments designed isolate molecular target tobacco...

Puccinia triticina (Pt), as the causal agent of wheat leaf rust, employs a plethora effector proteins to modulate immunity for successful colonization. Understanding molecular mechanisms underlying Pt effector-mediated susceptibility remains largely unexplored. In this study, an Pt_21 was identified interact with apoplast-localized thaumatin-like protein TaTLP1 using yeast two-hybrid assay and Pt_21-TaTLP1 interaction characterized. The between validated by in vivo co-immunoprecipitation...

Bacterial spot (BS), incited by Xanthomonas campestris pv. vesicatoria (Xcv), is one of the most serious diseases pepper. For a comparative analysis defense responses to Xcv infection, we performed transcriptomic susceptible cultivar, ECW, and resistant VI037601, using HiSeqTM 2500 sequencing platform. Approximately 120.23 G clean bases were generated from 18 libraries. From libraries generated, total 38,269 expressed genes containing 11,714 novel 11,232 differentially (DEGs) identified....

Drought stress often leads to heavy losses in mulberry planting, especially for fruits and leaves. Application of plant growth-promoting fungi (PGPF) endows various beneficial traits overcome adverse environmental conditions, but little is known about the effects on under drought stress. In present study, we isolated 64 from well-growing trees surviving periodical stress, Talaromyces sp. GS1, Pseudeurotium GRs12, Penicillium GR19, Trichoderma GR21 were screened out due their strong potential...

Thaumatin-like protein (TLP) plays an important role in combating plant pathogen infection. Common root rot caused by Bipolaris sorokiniana and leaf rust Puccinia triticina (Pt) are major fungal diseases wheat.
