What is Pierce's Disease?

Pierce's Disease is a bacterial infection, which is spread by bugs that feed on grapevines, particularly the "glassy winged sharpshooter." Grapevines that become infected with PD can quickly become sick and die.

Randomly amplified polymorphic DNA analysis of Vitis species and Florida bunch grapes

  • Author(s): Chen, Jianchi; Lamikanra, O.; Lu, J.; Wang, Y.;
  • Abstract: Randomly amplified polymorphic DNA (RAPD) analysis was performed on 42 accessions of Vitis, representing 13 species. Inter- and intra-specific/varietal variation were observed. Principal component analysis of Nei and Lis similarity index separated V. rotundifolia from other bunch-grape species. Within the bunch-grape species, V. vinifera, the North American bunch grapes, and the East Asian bunch grapes formed three separate RAPD clusters. RAPD analysis also demonstrated its sensitivity by detecting the genetic diversity within Florida bunch-grape cultivars. RAPD analysis, together with the published morphological data, will lead to a more comprehensive understanding of Vitis genetic diversity.
