Abstract:
DNA 1 is a single-stranded DNA molecule of approximately 1370 nucleotides. It is associated with monopartite geminiviruses of the genus Begomovirus, which require a DNA beta component for symptomatic infection. The DNA 1 molecule requires the helper begomovirus for movement in plants, but is capable of self-replication. We designed two abutting primer pairs (DNA101/DNA102 and UN101/UN102) to conserved sequences of DNA 1. This allowed polymerase chain reaction-mediated amplification of the full-length molecule from total nucleic acid extracts produced from various host plants from geographically distinct, worldwide locations. These primers are useful both as diagnostic probes and for producing full-length infectious clones for in planta studies.
