The invention relates to
Nymphaea tetragona
DNA fingerprint, a primer to acquire the same and a construction method of the
Nymphaea tetragona
DNA fingerprint and belongs to the technical field of
biology. The construction method of the
Nymphaea tetragona
DNA fingerprint comprises the specific steps of 1) extracting
Nymphaea tetragona DNA; 2) performing ISSR-PCR (inter-simple
sequence repeat-
polymerase chain reaction) amplification reaction and
electrophoresis detection, to be specific, amplifying
Nymphaea tetragona DNA with an ISSR primer, and electrophoretically detecting the ISSR-PCR productwith 1.8%
agarose gel, wherein the ISSR primer is from one or more of UBC840, UBC841, UBC811, UBC834, UBC835, UBC843, UBC844, UBC845, UBC873, and UBC880; 3) constructing DNA fingerprint. A stripe amplified with a
Nymphaea tetragona ISSR-PCR
system established herein has good
repeatability and high polymorphism; the defects of domestic studies on Nymphaea tetragona
germplasm resource
genetic diversity and molecular mapping are overcome. The Nymphaea tetragona DNA fingerprint constructed via the method herein can act as basis to identify and classify corresponding primary
germplasm resources ofNymphaea tetragona, and also guarantee the classification and identification of new germplasms and new varieties and the protection of intellectual properties at molecular technical level.
