Abstract Disease suppressiveness is a complex phenomenon that assumed to be the resultant of actions local microbial antagonists in soil environments. Exploitation disease as tool manage pathogens hindered by our poor understanding this phenomenon. Here we investigated microbiome-based suppression potato cyst nematodes (PCN), and, end, four apparently homogeneous fields with an unexplained non-homogeneous PCN distribution were selected. We hypothesized patchy resulted from variation...
Abstract Frequencies of CpG and UpA dinucleotides in most plant RNA virus genomes show degrees suppression comparable to those vertebrate viruses. While pathways that target UpAs HIV-1 echovirus 7 restrict their replication have been partly characterised, whether an analogous process drives dinucleotide underrepresentation viruses remains undetermined. We examined phenotypes compositionally modified mutants potato Y (PVY) which or frequencies were maximised non-structural genes (including...
The activity of intracellular plant nucleotide-binding leucine-rich repeat (NB-LRR) immune receptors is fine-tuned by interactions between the and their partners. Identifying NB-LRR interacting proteins therefore crucial to advance our understanding how these function. A co-immunoprecipitation/mass spectrometry screening was performed in Nicotiana benthamiana identify host associated with resistance protein Gpa2, a CC-NB-LRR receptor conferring against potato cyst nematode Globodera pallida....
Polygonum ringspot virus (PolRSV) is a recently characterized Tospovirus reported in Italy. Northern blot analyses of PolRSV infections Nicotiana benthamiana and tomato plants showed that viral RNA species with nearly twice the length Small genomic (S-RNA) accumulated abundantly former host, but was not detected latter. Additional assays confirmed biogenesis this novel common to all isolates tested also an isolate Tomato spotted wilt (TSWV). Given its size, we hypothesized dimer molecule...
To identify host factors for tomato spotted wilt orthotospovirus (TSWV), a virus-induced gene silencing (VIGS) screen using tobacco rattle virus (TRV) was performed on Nicotiana benthamiana TSWV susceptibility. rule out any negative effect the plants' performance due to double viral infection, method optimized allow screening of hundreds clones in standardized fashion. normalize results obtained and between experiments, set controls developed evaluate consist manner both VIGS efficacy level...
The tripartite genome of the negative-stranded RNA virus Tomato spotted wilt orthotospovirus (TSWV) is assembled, together with two viral proteins, nucleocapsid protein and RNA-dependent polymerase, into infectious ribonucleoprotein complexes (RNPs). These proteins are, together, essential for replication transcription, yet our knowledge on host factors supporting these processes remains limited. To fill this gap, composition RNPs collected from TSWV-infected Nicotiana benthamiana plants,...
Cyst nematodes are considered a dominant threat to yield for wide range of major food crops. Current control strategies mainly dependent on crop rotation and the use resistant cultivars. Various crops exhibit single resistance (R) genes that able activate effective host-specific certain cyst nematode species and/or populations. An example is potato R gene Gpa2, which confers against (PCN), Globodera pallida population D383. Activation Gpa2 results in delayed response, characterized by layer...
