In order to cluster and identify 10 varieties of Chuxiong population of Camellia reticulata Lindl., the difference of DNA among the 10 varieties was detected by using Fourier transform infrared spectroscopy (FTIR), and then hierarchical cluster and principal component analysis based on average spectra of DNA was used to establish standard clustering and identifying model. The result indicated that (1) DNA fingerprints based on FTIR of the 10 varieties are different from each other, which is also supported by variance analysis (p < 0.05).(2) The rate of clustering of 30 samples is 100%. Likewise, the rate of identifying of 10 samples is 100% as well. (3) It was speculated based on clustering distance coefficients that Guomei (Variety 5) was formed by grafting the scion from the original old tree Xiangguo (Variety 1) to seedling from seed. The conclusion is that DNA FTIR is an effective manner of clustering and identifying Chuxiong population of C. reticulata Lindl., and can be used to calculate the origin of ancient Camellia tree.

“…These analytical tools, in combination with other sensitive spectroscopic methods i.e. circular dichroism (CD) and/or FTIR, which have been also applied for the resolution of structural changes introduced by cytosine methylation in model oligonucleotides [44,50] could contribute to the analysis of DNA methylation.…”

The electrochemical behavior and thermal stability of double stranded oligonucleotides containing 5-methyl-cytosine and 7-deaza-guanosine as nucleotide analogues, as well as of Jurkat genomic DNAs methylated to different degree were studied by ACV and SWV and by thernal denaturation analysis. ACV and SWV combined with thermal denaturation analysis of the natural and modified oligonucleotides gave information regarding the presence of methylation and the concomitant conformational changes. ACV and SWV of Jurkat DNA mixtures methylated to different degrees revealed a decrease of the peak heights with increasing methylation, indicating an increase of structural rigidity, in agreement with the thermal denaturation data. These results verify the, possibly local, conformational changes introduced by DNA methylation. The results obtained in all cases were reproducible.

“…Currently, correlation spectroscopy is an established method to facilitate the interpretation of spectra obtained from natural and synthetic compounds within a dynamic or reacting system [3,4]. The technique has been successfully applied to fluorescence, infrared, Raman, and UV spectra and generalized to include combinations of analytical methods such as mass spectroscopy or NMR with FT-IR [5][6][7]. Correlation spectroscopy is especially suited to the study of chemically reactive systems where spectral changes occur over time.…”
