Insights into epigenetics suggest a role of DNA methylation in regulating Chinese yam tuber shape [PDF]

BMC Plant Biology
Background Plant organ shape is an important trait in terms of economic efficiency in agriculture. The club-like or spindle-shaped underground tubers of Chinese yam (Dioscorea polystachya Turcz.) impede mechanical harvest resulting in unprofitable ...

Leaf physiological and transcriptomic analyses provide insights into the regulatory network underlying high yield in yam under directional cultivation [PDF]

BMC Plant Biology
Background Traditional cultivation of yam (Dioscorea polystachya Turcz.), a globally important tuber crop, is notoriously labor-intensive and inefficient. Directional cultivation (DC) is an innovative agronomic practice that utilizes physical constraints

Short-Term Continuous Cropping of Dioscorea polystachya Alters the Rhizosphere Soil Microbiome and Degrades Soil Fertility

Agronomy
Chinese yam (Dioscorea polystachya) serves as both a food crop and a traditional Chinese medicine herb, yet it suffers from severe continuous cropping obstacles, typically requiring a six-year fallow period before replanting.

A Protein from Dioscorea polystachya (Chinese Yam) Improves Hydrocortisone-Induced Testicular Dysfunction by Alleviating Leydig Cell Injury via Upregulation of the Nrf2 Pathway. [PDF]

Oxid Med Cell Longev, 2021
Leydig cell injury has been described as a primary driver of testicular dysfunction and is affected by oxidative stress. Dioscorea polystachya (Chinese yam) is used to improve testicular dysfunction in clinical and pharmacological research via its antioxidative activity, but the mechanisms underlying the beneficial effect of Chinese yam on testicular ...

Anatomical and histochemical features of the vegetative organs of Dioscorea polystachya (Dioscoreaceae)

Emirates Journal of Food and Agriculture, 2022
We investigated the anatomical and histochemical features of Dioscorea polystachya (Dioscoreaceae), an important food crop in China. The primary structures of D. polystachya include vertical tubers, adventitious roots, twining aerial stems, and leaves with bulblets. The vertical tubers have storage parenchyma with scattered vascular bundles, a cortical

Genetic relationship and species identification of Dioscorea polystachya Turcz. in Yams determined by ISSR, ISAP, SRAP and SCAR markers [PDF]

Genetic Resources and Crop Evolution, 2021
Abstract Dioscorea polystachya Turcz. is the authentic herb Yam in Chinese traditional medicine. In the medicine market, some relative species are misused as “Yams”, such as D. alata L., D. exalata C.T. Ting & M.C. Chang, D. persimili Prain et Burkill, D. fordii Prain et Burkill and D. japonica Thunb.

Determination via an Integration Strategy of the Potential Dermal ECM Reconstruction Mechanism by Which the WAW Formula Alleviates Skin Aging. [PDF]

J Cosmet Dermatol
ABSTRACT Background Traditional Chinese medicine (TCM) treats skin conditions and delays aging using specific formulas. TCM links skin health to internal organ functions: kidney qi deficiency accelerates aging, whereas spleen deficiency leads to dry, loose skin from insufficient qi and blood. The renowned spleen‐tonifying and kidney‐nourishing formula “
