the plant-pathogen interaction is a multifactor process that may lead to resistance or susceptible responses of plant to pathogens. during the arms race between plant and pathogens, various biochemical, molecular and physiological events are triggered in plant cells such as ros signaling, hormone activation and gene expression reprogramming. in plants, micrornas (mirnas) are key post-transcript...

While host immune receptors detect pathogen-associated molecular patterns to activate immunity, pathogens attempt to deregulate host immunity through secreted effectors. Fungi employ LysM effectors to prevent recognition of cell wall-derived chitin by host immune receptors, although the mechanism to compete for chitin binding remained unclear. Structural analysis of the LysM effector Ecp6 of th...

Botrytis cinerea, the causative agent of gray mold disease, is an aggressive fungal pathogen that infects more than 200 plant species. Here, we show that some B. cinerea small RNAs (Bc-sRNAs) can silence Arabidopsis and tomato genes involved in immunity. These Bc-sRNAs hijack the host RNA interference (RNAi) machinery by binding to Arabidopsis Argonaute 1 (AGO1) and selectively silencing host i...

Induction of innate immunity is essential for host survival of infection. Evasion and inhibition of innate immunity constitute a strategy used by pathogens, such as the highly virulent bacterium Francisella tularensis, to ensure their replication and transmission. The mechanism and bacterial components responsible for this suppression of innate immunity by F. tularensis are not defined. In this...

The noise immunity of radio communication systems based on IEEE 802.15.4–2020 and 802.15.4z–2020 standards under interference effect variable-duration impulse is investigated. simulation model a channel for estimation the bit error rate with different parameters developed using MATLAB. estimates standard modes taking into account structure transmitted data are obtained. comparison between chara...

Innate immunity is crucial in the response and defense against pathogens for invertebrates and vertebrates alike. The soil nematode Caenorhabditis elegans is a useful model to study the eukaryotic innate immune response to microbial pathogenesis. Prior research indicates that the protein receptor FSHR-1 plays an important role in the innate recognition of intestinal infection due to pathogen co...

Horizontal gene transfer (HGT) in bacteria and archaea occurs through phage transduction, transformation, or conjugation, and the latter is particularly important for the spread of antibiotic resistance. Clustered, regularly interspaced, short palindromic repeat (CRISPR) loci confer sequence-directed immunity against phages. A clinical isolate of Staphylococcus epidermidis harbors a CRISPR spac...

The effects of carrageenan and trypan blue on the expression of adoptive immunity to the syngeneic guinea pig line 10 hepatoma were investigated. Adoptive immunity was assessed by observing dermal tumor growth in recipients of immune cells and by bioassays in which tumor challenge sites were transplanted into secondary hosts. Carrageenan abrogated transferred immunity in treated animals as evid...

In this paper we compare the performance of OFDM with a cyclic prefix (CP) and isotropic orthogonal transform algorithm (IOTA) OFDM without cyclic prefix under typical system imperfections such as channel estimation errors and frequency offset. The IOTA-OFDM system is based on offset quadrature amplitude modulation (OQAM) and promises an increased immunity to both inter-carrier interference (IC...
