Seed plants comprise angiosperms and gymnosperms. The latter includes gnetophytes, cycads, Ginkgo, and conifers. Conifers are distributed worldwide, with 630 species distributed across eight families and 70 genera. Their distinctiveness has triggered much debate on their origin, evolution, and phylogenetic placement among seed plants. To better understand the evolution of gymnosperms and their relation to other seed plants, we report here a high-quality genome sequence for a tree species, Chinese fir (Cunninghamia lanceolata), which has excellent timber quality and high aluminum adaptability and is a member of Cupressaceae with high levels of heterozygosity. We assembled an 11.24 Gb genome with a contig N50 value of 2.15 Mb and anchored the 10.89 Gb sequence to 11 chromosomes. Phylogenomic analyses showed that cycads sister to Ginkgo, which place to sister in all gymnosperm lineages, and Gnetales within conifers sister to Pinaceae. Whole-genome duplication (WGD) analysis showed that the ancestor of seed plants has differentiated into angiosperms and gymnosperms after having experienced a WGD event. The ancestor of extant gymnosperm has experienced a gymnosperm-specific WGD event and the extant angiosperms do not share a common WGD before their most recent common ancestor diverged into existing angiosperms lineages. Analysis of the MADS-box gene family of C. lanceolata revealed the developmental mechanism of the reproductive organs in C. lanceolata, which supported the (A)B(C) model of the development of gymnosperms reproductive organs. In addition, astringent seeds and shedding of whole branches (with withered leaves) might be a strategy of C. lanceolata that evolved during long-term adaptation to an aluminum-rich environment. The findings also reveal the molecular regulation mechanism of shade tolerance in C. lanceolata seedlings. Our results improve the resolution of ancestral genomic features within seed plants and the knowledge of genome evolution and diversification of gymnosperms.

“…Translocation processes in soils were significantly more visible in the control forest grasslands than in the forest-steppes. Due to the more humid, colder climate (Lapenis, et al 2008), and the strengthening influence of the forest vegetation (Hubová, et al 2018; Smolíková, 1967), the forest-grassland soils, Luvisols, showed a clearly developed metamorphic illuvial argic Bt horizon and at the same time an eluvial E horizon. On the other hand, forest-steppe soils, Phaeozems, were in an initial stage of (e.g.…”

The most species-rich grasslands worldwide are known from the Carpathian Mts and their periphery in East-Central Europe. They occur in forest-steppe regions, transitional between temperate forest and arid steppe biomes. Their climate, largely suitable for forests, raises questions about the origin of these grasslands. Have they been forested in the past, or locally maintained through a disturbance regime? We addressed these questions to contribute to the broader understanding of Holocene dynamics of open habitats in temperate Europe. We employed soil charcoal analysis and soil morphology to reconstruct past representation of woody species with fine spatial resolution. Our study area was Romanian Transylvania, a region renowned for a well-developed forest-steppe. Six soil profiles along a climatic gradient were assessed: four in forest-steppe grasslands, two in grasslands in adjacent forest region. The results revealed profound differences between forest-steppe and forest grasslands. Forest-steppe profiles showed Phaeozems with low specific anthracomass and continuous dominance by Juniperus, suggesting a long-term presence of grasslands. Forest profiles showed Luvisols with higher anthracomass and abundant charcoal of broad-leaved trees, indicating establishment after deforestation. The high radiocarbon ages of charcoals in basal soil horizons point to a glacial origin of soils and the link of forest-steppe grasslands to glacial forests. Siberian hemiboreal forests and related grasslands may be modern analogues of the reconstructed ecosystems, sharing many species with present day forest-steppe. We highlight the role of disturbances such as fire, herbivore grazing, and human activities in shaping the forest-steppe over time, contributing to the formation of today's richest grasslands.

“…The ion chromatography method using the ICS 1600 and ICS 6000 systems (Dionex, USA) was used to determine the basic inorganic anions and small organic acids in the extract (citrate, oxalate, malate, lactate, acetate, formate, butyrate, valerate, tartrate and isocitrate). The analysis was performed on an AS11-HC analytical and guard column with a KOH mobile phase and a gradient of 1-35.2 mM for 1-65 min (Hubová et al 2018). The chromatograms were processed using Chromeleon 6.80 (Dionex, USA).…”

The growth of shrubs in the Arctic is a key factor affecting environmental and vegetation changes framed by the currently accelerated dynamics of global warming. One of the phenomena involved in the shrubification of the Arctic is root exudation, which plays a part in nutrient acquisition by plants and thus the growth of both individual plants and whole communities. It is not known, however, to what extent root exudation differs across different environments in the Arctic tundra, how importantits role is in covering the nutrient demands of plants and what significance this might have for soil properties and vegetation succession. To shed light on the topic, we studied the content of biogenic elements in soils of different maturity following deglaciation, the age structure of the climax species Salix polaris, exudation by its roots,and the concentrations of different nutrients in its roots and leaves in the forefield of the Nordenskiöld glacier in the Svalbard archipelago. Our results reveal that polar willow shrubs have a greater relative propensity towards exudation, and thus larger potential for investing into growth, under more severe environmental conditions, which may be attributable to the stage of their root system development or the level of competition they face. This finding should be taken into consideration when interpreting current vegetation development and plant succession in the Arctic. Nevertheless, to what extent this relationship stays stable in the context of ongoing climate change remains a question to be explored.
