PAW-plasma activated water-triggers plant defence responses

ABSTRACT: Nowadays one of the main challenges is moving towards an eco-sustainable agriculture, able to preserve the food production through a reduced use of pesticides. The current global food sustenance by intensive agriculture mainly based on economic crop monocultures drastically reduces the biodiversity increasing the yield losses due to biotic and abiotic stress. To try to ensure yield stability also enhancing the plant resistance responses to promote an eco-sustainable management of plant diseases, a technology based on plasma activated water (PAW), characterized by the production of reactive oxygen and nitrogen species, was tested. Differential expression levels of selected genes involved in the plant defence pathways and the microRNAs composition in PAW treated- micropropagated periwinkle shoots and grapevines were analyzed. The results indicate that PAW treatment enhances plant defence responses at both, transcriptional and post-transcriptional level, leading to an increased synthesis in periwinkle of vinblastine and vindoline, anti-oxidant compounds employed in the pharmaceutical industry and in grapevine of resveratrol that is an important compound for human health.

Microbial communities of wheat plants inoculated with endophytic bacterium Enterobacter sp. SA187

Project description:Global warming has become a critical challenge to food safety, causing severe yield losses of major crops worldwide. Here, we report that the endophytic bacterium Enterobacter sp. SA187 induces thermotolerance of crops in a sustainable manner. Microbiome diversity of wheat plants is positively influenced by SA187 in open field agriculture, indicating that beneficial microbes can be a powerful tool to enhance agriculture in open field agriculture.

Transcriptomic profiling of Arabidopsis hypocotyls of brl3 mutants and tissue-specific overexpressors under elevated temperatures

Project description:Climate change is having a drastic impact on global agriculture. Indeed stress factors such as elevated temperature, drought and rising atmospheric CO2 reduce arable land surface, crop cultivation and yield and overall sustainable food production on earth. However, plants possess immense innate adaptive plasticity and a more in-depth understanding of the underlying molecular mechanisms is crucial to strategize for sustaining populations under worsening climate change. Brassinosteroids (BRs) are constitutive plant growth regulators that also control plant adaptation to abiotic stress. Downstream components of the BR biosynthetic pathway, BES1/BZR1 play central role in thermomorphogenesis, but involvement of the BR receptors is not well understood. Here, we show that the BRL3 receptor is essential for plant adaptation to warmer environment. The brl3 mutants lack thermal responsiveness and the BRL3 overexpression causes hyper-thermomorphogenesis response. BRL3 activates canonical BRI1 pathway upon elevated temperature. Further, phloem-specific expression of BRL3 completely rescues the growth adaptation defects of the brl3 mutant. This ability of BRL3 represents a previously unknown thermoresponsive mechanism specifically from phloem and uncouples the roles of BR receptors in generic growth vs adaptation to changing climate conditions.

Aging effect on interfollicular epidermis (paw skin)

Project description:We have employed whole genome microarray expression profiling to identify genes with the potential to distinguish young and aged interfollicular epidermis. Gene expression of paw whole skin samples from 4 young (6 week-old) and 4 aged (102 week-old) C57BL6 mice was analyzed.

Characterizing microbiome-directed fibre snacks in gnotobiotic mice and humans

Project description:Knowledge of the interrelationships between what we eat and the configurations of our gut microbial communities is providing important insights into how food components that are not directly metabolized by human enzymes are linked to our physiology and health status. Changing food preferences brought about by Westernization that have deleterious health effects1,2, plus rapid population expansion, ongoing challenges to sustainable agriculture, and other forces contributing to increased food insecurity, are catalyzing efforts to identify more nutritious and affordable foods3. The gut microbial community is complex, dynamic, and exhibits considerable intra- and interpersonal variation in its composition and functions. The massive number of potential interactions between its components makes it challenging to define the mechanisms by which food ingredients affect community properties. There is also a paucity of information about the Ã¢Â€Â˜bioactiveÃ¢Â€Â™ ingredients of foods that influence the fitness and expressed functions of community members. Here, plant fibres, from different sustainable sources and targeting distinct features of obese human gut microbiomes in gnotobiotic mice, were formulated into snack prototypes and used to supplement controlled diets consumed by overweight and obese adults; the results revealed fibre-specific changes in their microbiomes that were linked to changes in their plasma proteomes indicative of altered physiologic state.

Transcriptome analysis of mycorrhizal and non-mycorrhizal soybean root associated with F. virguliforme inoculation

Project description:Many of the microorganisms that are normally present in the soil, actually inhabit the rhizosphere and interact with plants. Those plant–microorganisms interactions may be beneficial or harmful. Among the first are the arbuscular mycorrhizal fungi (AMF). These soil fungi have been reported to improve plant resistance/tolerance to pests and diseases. On the other hand, soilborne pathogens represent a threat to agriculture generating important yield losses, depending upon the pathogen and the crop. One example is the “Sudden Death Syndrome” (SDS), a severe disease in soybean (Glycine max (L.) Merr) caused by a complex of at least four species of Fusarium sp., among which Fusarium virguliforme and F. tuccumaniae are the most prevalent in Argentina. This study provides, under strict in vitro culture conditions, a global analysis of transcript modifications in mycorrhizal and non-mycorrhizal soybean root associated with F. virguliforme inoculation. Microarray results showed qualitative and quantitative changes in the expression of defense-related genes in mycorrhizal soybean, suggesting that AMF are good candidates for sustainable plant protection against F. virguliforme.

Gene expression in Krt16 null paw lesions relative to WT paw skin

Project description:The type I intermediate filament keratin 16 (Krt16 gene; K16 protein) is constitutively expressed in ectoderm-derived appendages and volar palmar/plantar epidermis, and is otherwise inducibly expressed in non-volar epidermis when skin epithelia are under stress. Mutations at the (human) KRT16 locus can cause pachyonychia congenita (PC) and focal non-epidermolytic palmoplantar keratoderma (PPK), which each entail painful calluses on palmar and/or plantar skin. Krt16 null mice develop footpad lesions that mimic several aspects of PC-associated PPK and FNEPPK, including hypoactive Keap1-Nrf2 signaling and elevated expression of skin barrier homeostasis genes and Danger Associated Molecular Patterns (DAMPs). This provides a unique opportunity to understand the intricacies of PPK and devise effective therapies (see Lessard and Coulombe, J. Invest. Dermatol. 2012; Lessard et al. PNAS (USA) 2013; Kerns et al. J. Clin. Invest. 2016; Kerns et al., J. Invest. Dermatol. 2018; Zieman and Coulombe Exp. Dermatol. 2018). Here, we report on insight gained from a genome-wide analysis of gene expression in PPK-like lesions of Krt16 null mice. In this dataset, we include expression data obtained from Krt16 null paw skin lesions and WT littermate controls (C57Bl/6 strain background) at two months of age.
