The chemical investigation of one symbiotic strain, Aspergillus fumigatus D, from the coastal plant Edgeworthia chrysantha Lindl led to the isolation of eight compounds (1–8), which were respectively identified as rubrofusarin B (1), alternariol 9-O-methyl ether (2), fonsecinone D (3), asperpyrone A (4), asperpyrone D (5), fonsecinone B (6), fonsecinone A (7), and aurasperone A (8) by a combination of spectroscopic methods (1D NMR and ESI-MS) as well as by comparison with the literature data. An antimicrobial assay showed that these aromatic polyketides exhibited no remarkable inhibitory effect on Escherichia coli, Staphyloccocus aureus and Candida albicans. The genomic feature of strain D was analyzed, as well as its biosynthetic gene clusters, using antibiotics and Secondary Metabolite Analysis Shell 5.1.2 (antiSMASH). Plausible biosynthetic pathways for dimeric naphtho-γ-pyrones 3–8 were first proposed in this work. A non-reducing polyketide synthase (PKS) gene D8.t287 responsible for the biosynthesis of these aromatic polyketides 1–8 was identified and characterized by target gene knockout experiment and UPLC-MS analysis.

Features of reservoirs use make it necessary to collect, analyse and synthesise environmental information about the state of hydroecosystems with a purpose of their development forecast. Overgrowing processes are an important indicator of ecosystem. The following paper contains the results of the study of Chernovskoe reservoir flora and vegetation in different years. Floristic diversity is compared with other reservoirs and hydro botanic information about them has already been published in a number of the authors papers. The comparative analysis has shown that the overall composition of reservoirs flora is random, while there is some regularity in the environmental spectrum - each of them is characterized by a small number of aquatic species and by the dominance of coastal plant species. The study of Chernovskoe reservoir vegetation has shown that the composition of dominants has changed over the past 40 years, from 1974 to 2015. There is a dominance of air water vegetation above the water one, but the borders of the water vegetation growth have widened. Chernovskoe reservoir is currently in dynamic equilibrium. The lifetime of aquatic ecosystem at this stage may be unlimited if there is an unstable hydro regime and impulsive character of water use. The reservoir water level lowering may lead to overgrowth and accelerate activation of waterlogging.

To date, most research conducted on plant viruses has centred on agricultural systems where viruses greatly reduce economic output. Introduced viruses are globally common and there is a lack of knowledge around how they might affect natural populations. Although it has been suggested that infectious disease may have played an underestimated role in past species extinctions, there is little empirical evidence. Cook’s scurvy grass (Lepidium oleraceum Sparrm. ex G.Forst; Brassicaceae) is a threatened coastal plant endemic to New Zealand. Following the discovery of Turnip mosaic virus (TuMV) in some glasshouse cultivated specimens, we surveyed wild extant Lepidium populations on the Otago coast for TuMV while screening for two other common crop viruses. We show that TuMV is almost ubiquitous among remaining wild L. oleraceum populations on the South Island’s east coast and report the first record of L. oleraceum as a host for both Cauliflower mosaic virus and Turnip yellows virus. The high incidence of virus infection throughout the study populations may make this system one of the first examples of introduced viruses affecting the conservation of a threatened plant species.
