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.

Genetic diversity in intraspecific hybrid populations of Eucommia ulmoides Oliver evaluated from ISSR and SRAP molecular marker analysis

J. Yu, Wang, Y., Ru, M., Peng, L., and Liang, Z. S., Genetic diversity in intraspecific hybrid populations of Eucommia ulmoides Oliver evaluated from ISSR and SRAP molecular marker analysis, vol. 14, pp. 7417-7425, 2015.

Eucommia ulmoides Oliver, the only extant species of Eucommiaceae, is a second-category state-protected endangered plant in China. Evaluation of genetic diversity among some intraspecific hybrid populations of E. ulmoides Oliver is vital for breeding programs and further conservation of this rare species. We studied the genetic diversity of 130 accessions from 13 E. ulmoides intraspecific hybrid populations using inter-simple sequence related (ISSR) and sequence-related amplified polymorphism (SRAP) markers.
