Molecular identity of ramie germplasms using simple sequence repeat markers

M. B. Luan, Chen, B. F., Zou, Z. Z., Zhu, J. J., Wang, X. F., Xu, Y., Sun, Z. M., and Chen, J. H., “Molecular identity of ramie germplasms using simple sequence repeat markers”, vol. 14, pp. 2302-2311, 2015.

DNA identity is highly effective and efficient for distinguishing crop varieties regardless of their phenotypic similarities. To establish DNA identity in ramie, 21 simple sequence repeat primers were amplified in 108 accessions of domestic and exotic ramie germplasms. Sixty polymorphic bands were obtained, with an average of 2.9 bands per locus and 2-8 band types per primer locus (average of 5.19 band types). The Simpson’s diversity index of the 21 simple sequence repeat loci ranged from 0.158 to 0.808 with an average of 0.612.

Plant molecular identity (ID) is used to describe molecular characteristics of plants, which should contain all of the necessary information. Using inter-simple sequence repeat (ISSR) primers, molecular ID can be described in a way that reflects the polymerase chain reaction (PCR) conditions, annealing temperature, and the bands obtained in PCR amplification. A new complete molecular ID system is described in this study, which can be easily used and expanded to include more information.
