  • Special Issue of “International Journal of Molecular Sciences” on “Plant elicitors of resistance and the future of plant protection”

    The sustainable protection of plants relying on all tools and strategies that have minimal impact on human and environment health has become mandatory under the increasing demand and pressure from public opinion and, even more, under the dramatic challenges posed by climate change. In this context, an important role could be played by the elicitors of plant resistance as a valid alternative to the use of synthetic pesticides.  Strong evidence has accumulated on the role of plant-microorganism symbiosis, particularly at root level, in enhancing plant protection from biotic and abiotic stresses. Conversely, the study of the effects of abiotic elicitors, such as silicon, is still in its infancy.
    The species-specificity of these interactions and their final outcome require a thorough understanding of the molecular basis regulating them, in order to develop tools (and strategies) to be exploited in the near future for a sustainable approach in plant protection.

  • Virus-mediated export of chromosomal DNA in plants

    A new study, published in Nature Communications (https://www.nature.com/articles/s41467-018-07775-w), performed by the Institute for Sustainable Plant Protection of CNR and the University of Cambridge, documents the initial steps of virus-mediated horizontal transfer of chromosomal DNA between plant species. The propensity of viruses to acquire genetic material from relatives and possibly from infected hosts makes them excellent candidates as vectors for horizontal gene transfer. We report spontaneous and surprisingly efficient generation of hybrid virus/host DNA molecules in the form of minicircles during infection of sugar beet by a single-strand DNA virus. The hybrid minicircles replicated, became encapsidated into viral particles, and spread systemically throughout infected plants in parallel with the viral infection. Importantly, when co-infected with the virus, sugar beet DNA captured in minicircles replicated and was transcribed in other plant species. Thus, we have likely documented in real time the initial steps of a possible path of virus-mediated horizontal transfer of chromosomal DNA between plant species.

  • Special Issue of “Molecules” on “Recent Advances in Natural Products Chemistry Related to Metabolites and Microbiomes”

    The microbiome is generally referred to as the collective microbial genomes found in a particular habitat, while the microbiota is the set of microorganisms living in a specific environment. However, some authors use the term “microbiome” also to indicate the microbes that co-exist within complex communities. In this special issue the term “metabolites” refers only to the small molecules showing important functions in biological processes, with particular emphasis on secondary metabolites. The set of low molecular weight metabolites that are produced by organisms is defined as the “metabolome”. The components of the metabolome represent the end products of gene expression and define the biochemical status of an organism.
    In the special issue “Recent Advances in Natural Products Chemistry Related to Metabolites and Microbiomes” of the scientific journal “Molecules”, guest-edited by Dr. Francesco Vinale and Professor Maria Luisa Balestrieri, the following topics will be covered:

    • isolation of novel microbial compounds using metabolomic approaches;
    • molecules and metabolomes related with agricultural applications (crop and animal productions);
    • microbiomes and related natural products with beneficial effect in agriculture;
    • plant metabolites with bioactive properties;
    • influence of beneficial microbes and/or their metabolites on plant metabolome;
    • microbial metabolites involved in plant or animal interactions;
    • influence of production technologies on animal metabolomes and microbiomes.

    Full research papers, reviews, short communications reporting the finding and the characterization of molecules, metabolomes and related microbiomes showing their potential for agricultural applications both directly (e.g. increased nutritional value of crops) and indirectly (e.g. effects on the environment, agricultural practices, etc…), as well as their effects on health are invited for this editorial project. Deadline: 09 December 2019

  • Truffles’ smell of success is in their genes

    In the paper published online this week in Nature Ecology & Evolution (Murat et al., 2018), an international team led by Francis Martin, among which two Researchers at IPSP-CNR, Raffaella Balestrini and Antonietta Mello, has sequenced the genomes of the Piedmont white truffle (Tuber magnatum Pico) and the Burgundy black truffle (Tuber aestivum), as well as of lesser-known edible fungi such as the desert truffles (Terfezia boudieri), of pig truffles (Choiromyces venosus), and the genome of a black morel (Morchella importuna). Comparing these genomes with those of the already sequenced Perigord black truffle (Tuber melanosporum, Martin et al. 2010, Nature) the authors find unexpected genetic commonalities between the white and black truffle species, despite their separate evolutionary paths since their divergence over hundreds of millions of years. They also find that truffles have a limited set of the genes that allow other fungi to specialize in breaking down the cell walls of the plants on which they live. Instead, truffles finely tuned the expression of genes that produce smelly volatile organic compounds, generating the pungent aroma that attracts animals (famously pigs and truffle dogs) to disperse the truffle’s spores.

  • Lab tests demonstrate that Xylella is causing olive disease in Italy

    The pilot  project conducted by IPSP-CNR,  in collaboration with the University of Bari and “Centro di Ricerca, Sperimentazione e Formazione in Agricoltura” of Locorotondo, aimed at  “a better understanding of the susceptibility of some important  perennial crop species to the Apulian strain of  X. fastidiosa (denoted CoDiRO), by testing the susceptibility of major  Mediterranean crops such as grapes, citrus, peach and plum, but also of forest species such as oak or  other  temperate  trees.  [...] Results from needle inoculations revealed  the high susceptibility of olives, oleander and  Polygala  myrtifolia (high  rate  of  infected  plants)  to  the  CoDiRO  strain.  From  these  hosts,  the  bacterium  was  successfully  re-isolated  and  symptoms  resembling  those  associated  to  X.  fastidiosa (leaf  scorching, die back, discoloration) were recorded during the experiments. Conversely, the  experimental plants for  the  remaining  species  (citrus,  grapes  and  Q. ilex)  did  not  support  bacterial  infections  nor  developed  symptoms” (excerpt from the EFSA scientific Report). Therefore, Giuseppe Stancanelli, head of EFSA’s Animal and Plant Health Unit, stated: “These findings confirm that the CoDiRO strain of X. fastidiosa causes olive dieback”.
