Plant diversity in the Arctic and at high altitudes strongly depends on and rebounds to climatic and environmental variability and is nowadays tremendously impacted by recent climate warming. Therefore, past changes in plant diversity in the high Arctic and high-altitude regions are used to infer climatic and environmental changes through time and allow future predictions. Sedimentary DNA (sedDNA) is an established proxy for the detection of local plant diversity in lake sediments, but still relationships between environmental conditions and preservation of the plant sedDNA proxy are far from being fully understood. Studying modern relationships between environmental conditions and plant sedDNA will improve our understanding under which conditions sedDNA is well-preserved helping to a.) evaluate suitable localities for sedDNA approaches, b.) provide analogues for preservation conditions and c.) conduct reconstruction of plant diversity and climate change. This study investigates modern plant diversity applying a plant-specific metabarcoding approach on sedimentary DNA of surface sediment samples from 262 lake localities covering a large geographical, climatic and ecological gradient. Latitude ranges between 25°N and 73°N and longitude between 81°E and 161°E, including lowland lakes and elevated lakes up to 5168 m a.s.l. Further, our sampling localities cover a climatic gradient ranging in mean annual temperature between -15°C and +18°C and in mean annual precipitation between 36­ and 935 mm. The localities in Siberia span over a large vegetational gradient including tundra, open woodland and boreal forest. Lake localities in China include alpine meadow, shrub, forest and steppe and also cultivated areas. The assessment of plant diversity in the underlying dataset was conducted by a specific plant metabarcoding approach. We provide a large dataset of genetic plant diversity retrieved from surface sedimentary DNA from lakes in Siberia and China spanning over a large environmental gradient. Our dataset encompasses sedDNA sequence data of 259 surface lake sediments and three soil samples originating from Siberian and Chinese lakes. We used the established chloroplastidal P6 loop trnL marker for plant diversity assessment. The merged, filtered and assigned dataset includes 15,692,944 read counts resulting in 623 unique plant DNA sequence types which have a 100% match to either the EMBL or to the specific Arctic plant reference database. The underlying dataset includes a taxonomic list of identified plants and results from PCR replicates, as well as extraction blanks (BLANKs) and PCR negative controls (NTCs), which were run along with the investigated lake samples. This collection of plant metabarcoding data from modern lake sediments is still ongoing and additional data will be released in the future.

Since time immemorial, the natives were growing and maintaining plant diversity in the vicinity of dwelling places which is popularly known as Home Garden. The present study was conducted to assess role of home garden for in-situ conservation of plant diversity in Dhari Block, district Nainital, Uttarakhand with the major aim of understanding the plant diversity available especially with respect to the home gardens and role of vice-versa in their day to day life. With the help of questionnaire and survey, the information was collected from six villages i.e., Chaukuta, Dhanachuli, Gajar, Kasiyalekh, Podiyal and Pokhrar. Information regarding the occurrence of plant species, their local names, parts used and formulation through interviews and discussions held with elderly persons of rural communities were recorded. The study documented 93 plant species belonging to 79 genera and 51 families ranging from forestry to horticulture and agriculture including ethno-medicinal plants as grown in the home gardens and these plant species were used for multiple purposes i.e., Cereals, Fire woods, Fodders, Fruits, Leafy vegetables, Ornamentals, Pseudo-cereals, Spices, Vegetables and other cultural significance. These observations indicated that home garden play a important role in food security and in-situ conservation of agri-horticultural plants.

AbstractEvidence has been slowly accumulating that the urban home gardens of immigrants or transnational migrants in the USA conserve food plant diversity with roots in the developing world. Published species lists for home gardens indicate that, at least at the species level, this diversity is not novel but consists of widely grown, culturally important plant species that are also available through the horticultural trade. In 2018, we returned to the home garden of a Mexican-origin household in Chicago and confirmed the identity of a plant provisionally identified as Jaltomata darcyana during an earlier inventory of the garden. A recently named species of Central America, J. darcyana has not been previously recorded in cultivation. Collection of this species from a Chicago garden suggests that urban gardens may harbor other novel species awaiting documentation by urban ecologists and botanists.
