“…Hortorum Cultus, 23(1), 29-40. https://doi.org/10.24326/ asphc.2024.5247 Chinese yam bulbils, similar to buds, are generated from axillary meristems at the axil, which are sometimes referred to as aerial tubers [Murty and Purnima 1983]. Bulbils have chemical compositions and nutrient substances similar to those of the tuber, such as essential amino acids, polysaccharides, flavonoids, phenolic acids and diosgenin [Choi et al 2012, Narula et al 2003. It also provides a valuable food and medicinal ingredient source in people's everyday lives [Zhang et al 2018].…”

Bulbil germination is crucial to the survival of Chinese yam plants, the preservation of germplasm resources and the worldwide supply of food and natural medicine. There are still some unknowns regarding bulbil biochemical variations associated with germination. The metabolic changes during the germination of Chinese yam (Dioscorea polystachya Turczaninow) bulbils were studied using ultrahigh-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) at eight-time points covering all four phases of germination. It was determined that 27 metabolites, including organic acids, amino acids, sugars, lipid metabolites, phenolics and steroids, were responsible for the variation in the Chinese yam bulbil groups. A metabolomics pathway was proposed based on the identified metabolites. The main processes affected during germination were those related to carbohydrate metabolism, the TCA cycle, lipid metabolism, nitrogen metabolism, lipid metabolism and polyphenol metabolism. It is one of the earliest reports on the metabolite identification and profiling of Chinese yam bulbils at different germination stages.

“…The genetic diversity of D. bulbifera accessions from Africa, Asia, and Polynesia was subsequently assessed using random amplified polymorphic DNA (RAPD) (Ramser et al, 1996). This marker was also used to assess in vitro D. bulbifera regenerants by Dixit et al (2003) and Narula et al (2003). Amplified fragment length polymorphism (AFLP) markers were used to investigate the genetic diversity of 48 yam accessions from Ethiopia, including five D. bulbifera accessions (Tamiru et al, 2007).…”

ABSTRACT. Dioscorea is the largest genus in the Dioscoreaceae family, and includes a number of economically important species including the air yam, D. bulbifera L. This study aimed to develop new single sequence repeat primers and characterize the genetic diversity of local varieties that originated in several municipalities of Brazil. We developed an enriched genomic library for D. bulbifera resulting in seven primers, six of which were polymorphic, and added four polymorphic loci developed for other Dioscorea species. This resulted in 10 polymorphic primers to evaluate 42 air yam accessions. Thirtythree alleles (bands) were found, with an average of 3.3 alleles per locus. The discrimination power ranged from 0.113 to 0.834, with an average of 0.595. Both principal coordinate and cluster analyses (using the Jaccard Index) failed to clearly separate the accessions according to their origins. However, the 13 accessions from Conceição dos Ouros, Minas Gerais State were clustered above zero on the principal coordinate 2 axis, and were also clustered into one subgroup in the cluster analysis. Accessions from Ubatuba, São Paulo State were clustered below zero on the same principal coordinate 2 axis, except for one accession, although they were scattered in several subgroups in the cluster analysis. Therefore, we found little spatial structure in the accessions, although those from Conceição dos Ouros and Ubatuba exhibited some spatial structure, and that there is a considerable level of genetic diversity in D. bulbifera maintained by traditional farmers in Brazil.
