Genetic structure and diversity in the Dioscorea cayenensis/D. rotundata complex revealed by morphological and isozyme markers

E. A. Bressan, T. Neto, B., Zucchi, M. I., Rabello, R. J., and Veasey, E. A., Genetic structure and diversity in the Dioscorea cayenensis/D. rotundata complex revealed by morphological and isozyme markers, vol. 13, pp. 425-437, 2014.

Of the 600 known yam species, only 10 are utilized as food, and the Dioscorea cayenensis/D. rotundata species complex is among the most cultivated. In Brazil, these species are commercially cultivated in the northeast region and are cultivated in the south and southeast regions as subsistence crops by traditional agriculturists. This study aimed to evaluate the genetic diversity of 21 local varieties of D. cayenensis and 2 D.

Assessment of genetic diversity and variation of Robinia pseudoacacia seeds induced by short-term spaceflight based on two molecular marker systems and morphological traits

C. Q. Yuan, Li, Y. F., Sun, P., Sun, Y. H., Zhang, G. J., Yang, M. S., Zhang, Y. Y., Li, Y., and Wang, L., Assessment of genetic diversity and variation of Robinia pseudoacacia seeds induced by short-term spaceflight based on two molecular marker systems and morphological traits, vol. 11, pp. 4268-4277, 2012.

The black locust (Robinia pseudoacacia) is a forest legume that is highly valued as a honey plant and for its wood. We explored the effect of short-term spaceflight on development of R. pseudoacacia seedlings derived from seeds that endured a 15-day flight; the genetic diversity and variation of plants sampled from space-mutagenized seeds were compared to plants from parallel ground-based control seeds using molecular markers and morphological traits.
