Disruption of the S. sclerotiorum CAZymes arabinofuranosidase/β-xylosidase and an endo-β-1, 4-xylanase showed reduced or lost virulence [18], an indication of their importance in the growth and virulence of the pathogen.. (2) catalogue upregulated and downregulated genes in the S. At 72 hpi, the average percentage of reads mapping to the fungal genome in the S line was higher (68.1%) than...

Background: Bacillus subtilis strain NCD-2 is an excellent biocontrol agent against plant soil-borne diseases and shows broad-spectrum antifungal activities. This study aimed to explore some secondary metabolite biosynthetic gene clusters and related antimicrobial compounds in strain NCD-2. Fengycin, surfactin, bacillaene and bacillibactin were successfully detected from the fermentation broth of strain NCD-2 by UHPLC-QTOF-MS/MS. velezensis strain FZB42, whereas the identities...

Comparative transcriptome analysis of root, stem, and leaf tissues of Entada. phaseoloides reveals potential genes involved in triterpenoid saponin. Background: Entada phaseoloides (L.) Merr. The stem of Entada phaseoloides is popularly used as traditional medicine because of its significance in dispelling wind and dampness and remarkable anti-inflammatory activities. Triterpenoid saponins are the major bioactive compounds of Entada phaseoloides. Results: We...

Involvement of jasmonic acid, ethylene and salicylic acid signaling pathways behind the systemic resistance induced by Trichoderma longibrachiatum H9 in cucumber. To assess the impact of Trichoderma inoculation on the plant response, a multi-omics approach was performed in the Trichoderma-inoculated cucumber plants through the analyses of the plant transcriptome, proteome, and phytohormone content.. longibrachiatum H9. longibrachiatum H9 to cucumber roots...

In addition, the expression levels of the transcription factor (TF) PAP1 were significantly higher in TGY than in BS. Therefore, high accumulation of flavonoids, caffeine, and limonene metabolites and the expression patterns of their related genes in TGY might be beneficial for the formation of the “ Yin Rhyme ” flavor.. Conclusions: Transcriptomic, HPLC, and GC-MS analyses of TGY (Wei),...

Background: Members of the genus Bacillus are important plant growth-promoting rhizobacteria that serve as biocontrol agents. To further uncover the genetic mechanism of the plant growth- promoting traits of MDJK30 and its closely related strains, we used comparative genomics to provide insights into the genetic diversity and evolutionary relationship between B. licheniformis were evaluated by studying the phylogeny of the...

Background: Streptomyces clavuligerus ATCC 27064, the industrial producer of the β -lactamase inhibitor clavulanic acid, carries 49 putative secondary metabolite gene clusters. Construction of the S. clavuligerus pSCL4 − strain resulted in the excision of a 303 kb stretch in the right arm of the chromosome and its translocation to pSCL4, producing a 2.1 Mb plasmid named pSCL4*. Conclusions: The...

It usually stimulates declines in stomatal conductance and changes in the photochemical apparatus, which may eventually decrease photosynthetic rates (Boughalleb et al., 2017. Abdellaoui et al., 2017). To reduce the negative effects of salt stress, plants initiate different mechanisms, such as enzymatic antioxidants (Parida and Jha, 2010) and nonenzymatic low molecular compounds (Slama et al., 2015), to produce scavenging activity...

Terpenoids, essential oil composition, fatty acid profile, and biological activities of Anatolian Salvia fruticosa Mill.. Abstract: The hexane and dichloromethane extracts, obtained by re-extraction of the methanol extract of Salvia fruticosa Mill., afforded 7 diterpenoids (carnosol, carnosic acid, carnosic acid 12-methyl ether, rosmadial, isorosmanol, ferruginol, and manool), 4 triterpenoids (α -amyryltetracosanoate, oleanolic acid, ursolic acid, and erythrodiol), a steroid (3-acetylsitosterol),...
