Transcriptional and hormonal profiling of Fusarium graminearum-infected wheat reveals an association between auxin and susceptibility
Publication date: Available online 19 April 2019Source: Physiological and Molecular Plant PathologyAuthor(s): Elizabeth K. Brauer, Hélène Rocheleau, Margaret Balcerzak, Youlian Pan, François Fauteux, Ziying Liu, Li Wang, Wenju Zheng, Thérèse OuelletAbstractResistance to Fusarium graminearum, a fungal pathogen of cereals, has been associated with increased defense-associated hormonal responses in wheat. A comparison of susceptible (Roblin) and moderately resistant wheat genotypes (Wuhan 1, Nyubai) revealed transcriptional regulation of 1,021 genes during infection. Only 4% of these genes were uniquely differentially ex...

The role of MicroRNAs in defense against viral phytopathogens
Publication date: Available online 17 April 2019Source: Physiological and Molecular Plant PathologyAuthor(s): Behzad Hajieghrari, Naser Farrokhi, Bahram Goliaei, Kaveh KavousiAbstractMicroRNAs have been considered as an endogenous post-transcriptional gene silencing mechanism for transcription regulation. Additionally, reports are indicative of their involvement in plant viral defense. It seems that horizontal miRNA transfer from pathogenic viral and viroid genomes into plants has evolved into the counter-defense mechanism(s) against their invasions. miRNAs of a green alga and 16 other higher plant species, with/without en...

Publication date: Available online 9 April 2019Source: Physiological and Molecular Plant PathologyAuthor(s): M.M. Gutierrez-Pacheco, A.T. Bernal-Mercado, F.J. Vazquez-Armenta, M.A. Martinez-Tellez, G.A. Gonzalez-Aguilar, J. Lizardi-Mendoza, T.J. Madera-Santana, F. Nazzaro, J.F. Ayala-ZavalaAbstractPathogenic bacteria use Quorum sensing (QS) to regulate the expression of virulence factors involved in plant tissue infection. Some of these factors are the production of biofilm, hydrolytic enzymes, toxins, and plasmids; therefore, the interruption of this system could be a useful tool to control plant tissue infections.

RSI1/FLD is a positive regulator for defense against necrotrophic pathogens
Publication date: Available online 6 April 2019Source: Physiological and Molecular Plant PathologyAuthor(s): Vijayata Singh, Deepjyoti Singh, Janesh Kumar Gautam, Ashis Kumar NandiAbstractThe reduced systemic immunity 1 (rsi1) mutant of Arabidopsis (allelic to fld; flowering locus D) is essential for systemic acquired resistance (SAR). RSI/FLD codes for putative histone-demethylase and modulates flowering and defense response. The rsi1/fld mutants are defective in systemic SA accumulation upon pathogen challenge and fail to respond to the SAR signals in the distal tissues. However, the role of RSI1/FLD in ethylene (ET)-jas...

Salicylic acid deficient Nicotiana benthamiana attenuated virus induced gene silencing but did not affect transgene-induced posttranscriptional gene silencing nor general biogenesis of microRNAs
Publication date: Available online 5 April 2019Source: Physiological and Molecular Plant PathologyAuthor(s): Xiaohe Song, Xiaobao YingAbstractRNA interfering (RNAi) is a conserved mechanism in plants which plays a vital role in plant development, response to abiotic stress and biotic stress mediated by endogenous small RNAs and miRNAs as well as small RNAs originated from exogenic RNAs. Salicylic acid (SA) is an important signal in plant resistance to viral infection, functioning in R-gene mediated resistance as well as RNAi. NIbV3, Nicotiana benthamiana (N.benthamiana) transformed with nuclear inclusion b (NIb) gene of pl...

Effect of trisodium phosphate treatment on black spot of apple fruit and the roles of anti-oxidative enzymes
In this study, apple fruit (cv. Golden delicious) was used as the materials to study the effects of 0.25, 0.5, 1.0, 2.0 mg/mL trisodium phosphate (TSP) dipping treatment on lesion development of fruit inoculated with A. alternata. In vitro test was conducted to investigate the effect of TSP on mycelia growth of A. alternata. The optimal concentration of TSP was screened to assay its effect on the activity of anti-oxidative enzymes, the content of H2O2 and phenylpropane metabolites in apple fruit. The results showed that the different concentrations of TSP significantly inhibited mycelia growth of A. alternata and indicat...

Genome-wide identification of Lysin-Motif Receptor-Like Kinase (LysM-RLK) gene family in Brachypodium distachyon and docking analysis of chitin/LYK binding
Publication date: Available online 9 March 2019Source: Physiological and Molecular Plant PathologyAuthor(s): Guzin Tombuloglu, Huseyin Tombuloglu, Emre Cevik, Hussain SabitAbstractLysin-Motif Receptor-Like Kinase (LysM-RLK) family proteins have critical function in plant-microbe interaction. During infection, common peptide domain of these proteins, namely LysM, interacts with bacterial gylcans or fungal chitins which triggers; (1) plant immune responses, (2) plant defense responses, or (3) plant-microorganism symbiotic interactions. Since pathogenic diseases cause severe annual loss in cereals, a better understanding of t...

Piriformospora indica colonization reprograms plants to improved P-uptake, enhanced crop performance, and biotic/abiotic stress tolerance
Publication date: Available online 5 March 2019Source: Physiological and Molecular Plant PathologyAuthor(s): Mehtab Muhammad Aslam, Joseph Karanja, Suleiman Kehinde BelloAbstractPiriformospora indica is an endophytic fungus that promotes plant growth by establishing mutually beneficial alliances with plant roots reminiscent of arbuscular mycorrhizal fungi. It solubilizes soil inaccessible organic P to readily available Pi, thus, constitutes an indirect source of phosphate for plant growth under P limitation. In exchange, P. indica derives photosynthates (carbon) from host plant cell that is necessary for its metabolic proc...
