An Underutilized Orphan Tuber Crop—Chinese Yam : a Review
Planta (2020) 252:58 https://doi.org/10.1007/s00425-020-03458-3 REVIEW An underutilized orphan tuber crop—Chinese yam : a review Janina Epping1 · Natalie Laibach2 Received: 29 March 2020 / Accepted: 11 September 2020 / Published online: 21 September 2020 © The Author(s) 2020 Abstract Main conclusion The diversifcation of food crops can improve our diets and address the efects of climate change, and in this context the orphan crop Chinese yam shows signifcant potential as a functional food. Abstract As the efects of climate change become increasingly visible even in temperate regions, there is an urgent need to diversify our crops in order to address hunger and malnutrition. This has led to the re-evaluation of neglected species such as Chinese yam (Dioscorea polystachya Turcz.), which has been cultivated for centuries in East Asia as a food crop and as a widely-used ingredient in traditional Chinese medicine. The tubers are rich in nutrients, but also contain bioactive metabolites such as resistant starches, steroidal sapogenins (like diosgenin), the storage protein dioscorin, and mucilage polysaccharides. These health-promoting products can help to prevent cardiovascular disease, diabetes, and disorders of the gut microbiome. Whereas most edible yams are tropical species, Chinese yam could be cultivated widely in Europe and other temperate regions to take advantage of its nutritional and bioactive properties. However, this is a laborious process and agronomic knowledge is fragmented. The underground tubers contain most of the starch, but are vulnerable to breaking and thus difcult to harvest. Breeding to improve tuber shape is complex given the dioecious nature of the species, the mostly vegetative reproduction via bulbils, and the presence of more than 100 chromosomes. -

Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 25 June 2018 doi:10.20944/preprints201806.0398.v1 Abstract: The present study was conducted to investigate the effects of rhizome extract of Dioscorea batatas (Dioscoreae Rhizoma, Chinese Yam) and its bioactive compound, allantoin, on myoblast differentiation and mitochondrial biogenesis in skeletal muscle cells. Yams were extracted in water and the extract was analyzed by HPLC. The expression of C2C12 myotubes differentiation and mitochondrial biogenesis regulators were determined by reverse transcriptase (RT)-PCR or Western blot. The glucose levels and total ATP contents were determined by glucose consumption, glucose uptake and ATP assays, respectively. Treatment with yam extract (1 mg/mL) and allantoin (0.2 and 0.5 mM) significantly increased of MyHC expression compared with non-treated myotubes. -

INTRODUCTION This document is a summary of the Environmental and Social Impact Assessment (ESIA) of the Transport Sector Support Programme Phase 2 which involves the execution of works on the Yaounde-Bafoussam-Bamenda road. The impact assessment of the project was conducted in 2012. This assessment seeks to harmonize and update the previous one conducted in 2012. According to national regulations, the Yaounde-Bafoussam-Babadjou road section rehabilitation project is one of the activities that require the conduct of a full environmental and social impact assessment. This project has been classified under Environmental Category 1 in accordance with the African Development Bank’s Integrated Safeguards System (ISS) of July 2014.

Effect of Seed Tuber Weights on the Development of Tubers
J. Japan. Soc. Hort. Sci. 76 (3): 230–236. 2007. Available online at www.jstage.jst.go.jp/browse/jjshs JSHS © 2007 Effect of Seed Tuber Weights on the Development of Tubers and Flowering Spikes in Japanese Yams (Dioscorea japonica) Grown under Different Photoperiods and with Plant Growth Regulators Yasunori Yoshida1*, Harumi Takahashi1, Hiroomi Kanda1 and Koki Kanahama2 1Akita Prefectural College of Agriculture, Ohgata, Akita 010–0451, Japan 2Faculty of Agriculture, Tohoku University, Aobaku, Sendai 981–8555, Japan The effect of seed tuber (ST) weight on the development of main shoots, aerial tubers (bulbils, AT), new tubers (below ground, NT), and flowering spikes (inflorescences) was examined in Japanese yam plants (Dioscorea japonica) grown under different photoperiods and with plant growth regulators (PGRs). Within the same PGR and ST-weight group, the main shoot lengths of plants grown under a 24-h photoperiod (constant light, LD) were found to be longer than those grown under an 8-h photoperiod (SD) in all seasons. Furthermore, within the same photoperiod and ST-weight group, except for the plants grown from 25 g of ST (25gST plants) under SD conditions, the main shoot lengths of control and gibberellic acid (GA3)-treated plants were found to be longer than those of uniconazole-P (Uni)-treated plants. These tendencies were stronger in the 50gST plants than in the 25gST plants. In the 25gST plants, the final fresh weight (FW) of NT and the combined FW of AT and NT were greater in plants grown under LD conditions (LD plants) than those of SD plants; however, this was not observed in the case of the 50gST plants. -

Dioscorea Oppositifolia in Tripura
Pleione 8(1): 184 - 187. 2014. ISSN: 0973-9467 © East Himalayan Society for Spermatophyte Taxonomy Dioscorea oppositifolia Linnaeus [Dioscoreaceae] - a new distributional record for Tripura, India Chiranjit Paul1, Amal Debnath and Bimal Debnath Department of Forestry and Biodiversity, Tripura University, Suryamaninagar-799022, Tripura, India 1Corresponding Author: [email protected] [Received 08.04.2014; Revised 20.05.2014; Accepted 21.05.2014; Published 30.06.2014] Abstract The occurrence of Dioscorea oppositifolia Linnaeus (Dioscoreaceae) is recorded from the forest floor and the barren land in Tripura for the first time. The tuber of this plant is mostly popular to Chakma and Reang communities as delicious vegetable. The tuber is also applied externally to ulcers, boils and abscesses by different tribal inhabitant of the state. The Chakma community uses its leaf for the treatment of snakebites. The plant is rare in the state probably due to the loss of habitat by rubber plantation. Key words: Dioscorea oppositifolia, Distribution, New record, Ethnic uses, Tripura INTRODUCTION Dioscorea Linnaeus is a genus of over 600 species (Ayensu1972) of tuberous herbaceous angiospermic climbers, climbing to 20 meter on supports. The genus belongs to Dioscoreaceae of Dioscoreales. Species of Dioscorea are native throughout the tropical, especially in tropical America, subtropical and warm temperate regions of the world, with only a few species extending into the temperate regions (Caddick et al. 2002; Seikh et al. 2009). In India, so far 50 species of Dioscorea have been reported (Prain & Burkill 1936; Deb 1983) out of which 30 species are distributed in Arunachal Pradesh (Saikia et al. 2011). Ayensu & Coursey (1972) reported that Asia, South America and West Africa are the major yam growing regions in the world. -

Aldasoro Received 13 July 2012; accepted 29 December 2014 Abstract PLANT SPECIES AND COMMUNITIES IN POYANG LAKE, THE LARGEST FRESHWATER LAKE IN CHINA.— Studying plant species richness and composition of a wetland is essential when estimating its ecological importance and ecosystem services, especially if a particular wetland is subjected to human disturbances. Poyang Lake, located in the middle reaches of Yangtze River (central China), constitutes the largest freshwater lake of the country. It harbours high biodiversity and provides important habitat for local wildlife. A dam that will maintain the water capacity in Poyang Lake is currently being planned. However, the local biodiversity and the likely effects of this dam on the biodiversity (especially on the endemic and rare plants) have not been thoroughly examined.
