Fusarium circinatum is the causal agent of Pine Pitch Canker (PPC) of pines and established in the Iberian Peninsula in Europe only. However, it is hypothesized that its range could expand through the Europe in the near future. The disease is very harmful to forests and nurseries all around the world. Despite the aggressiveness of this fungus, no trials on the susceptibility of Ukrainian Scots pine provenances from Pinus sylvestris to F. circinatum have been performed. The first preliminary pathogenicity test was carried out in vitro and revealed the strong probability of high level of pine seedlings susceptibility to pitch canker.

The fungal pathogen Fusarium circinatum is the causal agent of Pine Pitch Canker (PPC), a disease which seriously affects different species of pine in forests and nurseries worldwide. In Europe, the fungus affects pines in northern Spain and Portugal, and it has also been detected in France and Italy. Here, we report the findings of the first trial investigating the susceptibility of Polish provenances of Scots pine, Pinus sylvestris L., to infection by F. circinatum. In a greenhouse experiment, 16 Polish provenances of Scots pine were artificially inoculated with F. circinatum and with six other Fusarium species known to infect pine seedlings in nurseries. All pines proved highly susceptible to PPC and displayed different levels of susceptibility to the other Fusarium spp. tested. The findings obtained indicate the potentially strong threat of establishment of an invasive pathogen such as F. circinatum following unintentional introduction into Poland.

Gazproms human capital (as HDI) is one of the most important resources of the corporation, which ensures its competitive strength in the Russian and international energy market. One of the main goals of PJSC Gazprom is the formation of a highly professional, responsible and cohesive team that effectively develops projects and solves a variety of tasks not only at the corporate level, but the country and the world. Therefore, the assessment of PJSC Gazprom staff readiness for the competition of the corporation in the domestic and external markets is relevant. Modeling the level of development of the enterprises human capital, based on the example of Gazprom corporation, according to certain indicators, determining their role in the development and competitiveness of the organization. To conduct the study, the works of scientists were analyzed, official data of the annual reports on the activities of PJSC Gazprom in the field of sustainable development for 2000-2018 were used. In order to assess the readiness of the corporation's human capital to sustainable development of the enterprise, a regression analysis and an econometric study were carried out using the MS Excel and Eviews10 application software packages. As a result of the study, it was found that a positive corporate human capital has a significant impact on competitiveness and an increase in the companys value and the constructed model for assessing companys human capital, based on the example of PJSC Gazprom, enables to make a forecast for the near future. Russia has occupied 49 place in the World Ranking (HDI = 0.824) in 2019 in terms of the level of development of the human capital according to the World Bank and has got into a very high level of development. Despite this fact, Russian HDI in World Ranking occupies only 46% against 70% of developed countries. World Bank experts claims, it will take Russia about 100 years to catch up with developed countries on this indicator. Russia does not have that kind of time, so the country has actively joined on every front. Obviously, the human capital of each corporation makes a certain contribution to changing the human capital of the country in one direction or another, and the human capital of PJSC Gazprom is able to significantly increase this indicator.

Nutrition is one of the factors that most limits forestry plant growth; thus, current production in nurseries is based on conventional fertilization focused on enhancing vigor. However, an excessive intake of mineral nitrogen can cause morphological imbalances and the formation of more succulent tissues which, consequently, increase susceptibility to plant pathogens. Fusarium circinatum is the causal agent of pitch canker in plants of the Pinus genus, with Pinus radiata being the species most susceptible to this disease. This study compares the response of P. radiata seedlings to infection by F. circinatum as influenced by two fertilizers—conventional and aerated compost tea (ACT)—applied during the nursery phase. The potential of ACT against F. circinatum was first tested in vitro, where it was found to inhibit the pathogen’s mycelial growth and conidial germination. In the greenhouse, infected plants fertilized with ACT exhibited less severe internal and external symptoms of pitch canker and lower levels of pathogen colonization of both stems and needles than with conventional fertilizer. An analysis of the hormone content and defense-related gene expression shows greater salicylic acid production and phenylalanine ammonium-lyase and chalcone synthase expression in ACT-fertilized pine. All of the parameters assessed are consistent in showing that biofertilization with ACT reduces the susceptibility of pine seedlings to the disease compared with conventional fertilization.

Fusarium circinatum is the causal agent of pine pitch canker (PPC), one of the most devastating forest diseases worldwide. This fungus causes severe damping-off in pine seedlings and growth reduction, wilting and the development of cankers in pine forests and plantations. A draft of the complete genome sequence of this phytopathogen was recently made available. This information was used to annotate in silico the gene Fcrho1 as a putative homolog of Rho1 GTPase genes. In this study, we generated Fcrho1 deletion mutants in two F. circinatum wildtype strains isolated from damaged trees in northern Spain. For that, we used a modified version of the OSCAR methodology, an approach not previously used in F. circinatum that allows the generation of deletion constructs in a single cloning step. The conidiation and spore germination of the resulting deletion mutants were not affected, neither the hyphal morphology. However, the mutant strains showed significantly reduced growth in vitro and more foamy macroscopic hyphal morphology than their corresponding ectopic and wildtype strains. Finally, an in vivo virulence assay showed that the reduced in vitro growth rate characteristic to the deletion mutants does not impact their pathogenicity.

The pitch canker fungus, Fusarium circinatum (teleomorph Gibberella circinata), was isolated from a branch originating from rootstock of a Douglas-fir (Pseudotsuga menziesii) graft in a breeding orchard at 1,000m elevation in El Dorado County, California. We visited the orchard after the New Zealand Ministry of Agriculture and Forestry reported in November 2003 that a Douglas-fir scion (branch cutting) shipped from there in January—and subsequently grafted and held in a quarantine facility near Christchurch—was infected with the pitch canker fungus. We took samples throughout the orchard of any branches that appeared unhealthy. In addition, asymptomatic branches from the tree alleged to be the source of the New Zealand infestation were collected to assay for propagules of F. circinatum. Wash water from these branches was negative for the pathogen. Likewise, F. circinatum was not recovered from water washings of 20 branches collected randomly throughout the orchard. Fifteen branch samples collected from symptomatic Douglas-fir grafts were cultured on water agar and only one yielded a colony with an appearance consistent with F. circinatum. A single spore subculture of this isolate was confirmed as F. circinatum on the basis of colony morphology and the structure of the microconidiophores (1). The virulence of this isolate was evaluated by inoculating susceptible 2-year-old Monterey pine (Pinus radiata) seedlings with a toothpick to wound the main stem and insert potato dextrose agar colonized by the fungus. Twenty-four days later, pitching and yellow needles were evident at the site of inoculation, and removal of the bark revealed resin-soaked and discolored tissue. Concurrent with the pathogenicity test described above, a culture of the putative F. circinatum isolated in New Zealand was inoculated into Monterey pines with an identical outcome. The fungus was reisolated from lesions from both sets of inoculations and confirmed as F. circinatum based on morphological criteria. Isolates GL285 and GL286 are available from T. R. Gordon upon request. Prior to its discovery in the Sierra Nevada, pitch canker in California was known only from counties on or near the coast. Our report indicates the pathogen can survive and infect trees 110 km east of the previous most-inland site of infestation. It remains to be seen how extensively pitch canker will develop in the Sierra Nevada. Douglas-fir is only moderately susceptible to F. circinatum, which has not been observed to cause significant damage to this species. On the other hand, low-elevation Sierra Nevada pines including P. sabiniana, P. coulteri, and P. ponderosa are substantially more susceptible than are Douglas-fir in greenhouse tests (2).

Epimedium elatum (Morren & Decne) of family Berberidaceace is a rare perennial medicinal plant, endemic to high altitude forests of Northwestern Himalayas in India. Ethnobotanically, it has been used as an ingredient for treatment of bone-joint disorders, impotence and kidney disorders in Kashmir Himalayas. Phytochemically, it is rich in Epimedin ABC and Icariin; all of these have been demonstrated to possess remarkable biological activities like PDE-5 inhibition (treatment of erectile dysfunction), anticancer, antiosteoporosis antioxidant and antiviral properties. The present investigation reports its traditional usage, comprehensive distribution and conservation status from twenty ecogeographical regions in Kashmir Himalayas, India. The species was reported from Gurez valley for the first time. Numerous threats like excessive grazing, deforestration, habitat fragmentation, tourism encroachment, landslides and excessive exploitation have decreased its natural populations in most of the surveyed habitats. Consequently, its existence may become threatened in near future if timely conservation steps are not taken immediately by concerned stakeholders involved in medicinal plant research. Moreover, use of plant tissue culture techniques is recommended for development of its in vitro propagation protocols. Therefore, introduction of this medicinal plant in botanical gardens, protected sites and development of monitoring programmes are needed for its immediate conservation in Northwestern Himalayas, India.

Margaret Atwood, one of the most spectacular authors of postmodern movement, achieved to unite debatable and in demand critical points of 21st century such as science fiction, postmodernism and ecocriticism in the novel The Year of The Flood written in 2009. The novel could be regarded as an ecocritical manifesto and a dystopic mirror against today’s degenerated world, tending to a superficial base to keep the already order in use, by moving away from the fundamental solution of all humanity: nature. Although Atwood does not want her works to be called science fiction, it is obvious that science fiction plays an introductory role and gives the novel a ground explaining all ‘why’ questions of the novel. However, Atwood is not unjust while claiming that her works are not science fiction because of the inevitable rapid change of 21st century world becoming addicted to technology, especially Internet. It is easily observed by the reader that what she fictionalises throughout the novel is quite close to possibility, and the world may witness in the near future what she creates in the novel as science fiction. Additionally, postmodernism serves to the novel as the answerer of ‘how’ questions: How the world embraces pluralities, how heterogeneous social order is needed, and how impossible to run the world by dichotomies of patriarchal social order anymore. And lastly, ecocriticism gives the answers of ‘why’ questions of the novel: Why humanity is in chaos, why humanity has organized the world according to its own needs as if there were no living creatures apart from humanity. Therefore, The Year of The Flood meets the reader as a compact embodiment of science fiction, postmodernism and ecocriticism not only with its theme, but also with its narrative techniques.

The new SARS-CoV-2 belonging to the coronaviruses family has caused a pandemic affecting millions of people around the world. This pandemic has been declared by the World Health Organization as an international public health emergency. Although several clinical trials involving a large number of drugs are currently underway, no treatment protocol for COVID-19 has been officially approved so far. Here we demonstrate through a search in the scientific literature that the traditional Moroccan pharmacopoeia, which includes more than 500 medicinal plants, is a fascinating and promising source for the research of natural molecules active against SARS-CoV-2. Multiple in-silico and in-vitro studies showed that some of the medicinal plants used by Moroccans for centuries possess inhibitory activity against SARS-CoV or SARS-CoV-2. These inhibitory activities are achieved through the different molecular mechanisms of virus penetration and replication, or indirectly through stimulation of immunity. Thus, the potential of plants, plant extracts and molecules derived from plants that are traditionally used in Morocco and have activity against SARS-CoV-2, could be explored in the search for a preventive or curative treatment against COVID-19. Furthermore, safe plants or plant extracts that are proven to stimulate immunity could be officially recommended by governments as nutritional supplements.
