Mutagenic influences of colchicine on phenological and molecular diversity of Calendula officinalis L.

Y. I. El-Nashar, Ammar, M. H., El-Nashar, Y. I., Ammar, M. H., El-Nashar, Y. I., and Ammar, M. H., Mutagenic influences of colchicine on phenological and molecular diversity of Calendula officinalis L., vol. 15, p. -, 2016.

Six different colchicine concentrations: 0, 400, 800, 1200, 1600, and 2000 ppm, in combination with four soaking time treatments (1, 2, 3, and 4 h), were selected to assess the effects on germination, vegetative growth, and flower yield components in calendula plants. The molecular diversity among the treatments was assessed using ten SRAP marker combinations. Seed soaking in colchicine significantly enhanced both the fresh and the dry shoot and root masses, flowering date, number of flowers per plant, and flower diameter.

Molecular variation of Sporisorium scitamineum in Mainland China revealed by internal transcribed spacers

Y. Y. Zhang, Huang, N., Xiao, X. H., Huang, L., Liu, F., Su, W. H., and Que, Y. X., Molecular variation of Sporisorium scitamineum in Mainland China revealed by internal transcribed spacers, vol. 14, pp. 7894-7909, 2015.

Sugarcane smut caused by the fungus Sporisorium scita­mineum is a worldwide disease and also one of the most prevalent diseases in sugarcane production in mainland China. To study molecular variation in S. scitamineum, 23 S. scitamineum isolates from the 6 primary sugar­cane production areas in mainland, China (Guangxi, Yunnan, Guangdong, Hainan, Fujian, and Jiangxi Provinces), were assessed using internal tran­scribed spacer (ITS) methods.
