Plant cultivars are important germplasm resources for
socio-economic development. However, it is difficult to conduct accurate
genetic evaluation on plant diversity solely on the basis of morphological
traits which are easily affected by environmental conditions and may change
during developmental stages of the planta.
Developing
DNA markers with high resolution and sensitivity, especially at cultivar
level, is a global challenge. We report a good methodology for rapid and
efficient detection of plant genetic diversity at cultivar level.
A unique nucleotide molecular formula (NMF) was constructed
for each crape myrtle using polymorphic nucleotide sites. Our results showed
that the DNA sequence from chromatin remodeling gene region of the
ubiquitin-proteasome system is useful for molecularly characterizing crape
myrtle cultivars.
