SPECTROCHIMICA ACTA. PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2019; 213:330-336. [PMID: 30711903 DOI: 10.1016/j.saa.2019.01.064] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/23/2018] [Revised: 12/26/2018] [Accepted: 01/20/2019] [Indexed: 06/09/2023]
Abstract
To date there is no any study on imaging molecular chemistry and chemical structure of biotech-modified plant tissue on a molecular basis. The objective of this methodology study was to apply a non-invasive and non-destructive synchrotron powered technology - SR-IMS to image molecular chemistry of the modified forage leaf tissue. The infrared molecular vibrational microspectroscopy powered with synchrotron light at Advanced Light Source (ALS, Lawrence Berkeley National Lab, Berkeley, California, Dept. of Energy, USA) were applied. The synchrotron beamline time was arranged by National Synchrotron Light Source (Scientist Dr. Lisa Miller, Brookhaven National Lab, Dept. of Energy, USA). The various molecular functional groups in the forage tissue included CH symmetric and asymmetric regions, amides I and II regions, structure and non-structure CHO regions, carbonyl ester region with peak areas at ca. 3644-3000 cm-1, ca 3005-2979 cm-1, ca. 1722-1483 cm-1, ca. 1488-1412 cm-1, ca. 1296-1189 cm-1, and ca. 1194-951 cm-1. The spectral peak area ratio imaging of chemical functional groups were also studied which included the ratio of peak area under ca. 1722-1483 cm-1 to peak area under ca. 3005-2979 cm-1 and the ratio of peak area under ca. 1722-1483 cm-1 to peak area under ca. 1194-951 cm-1. The results showed that the advanced synchrotron-based technology - SR-IMS was able to image the forage tissue at an ultra-highly resolution within intact tissue within cellular and subcellular dimension. It revealed the forage tissue in a molecular chemical sense and provided an insight on nutrient properties and their molecular structure as well as chemical features. In conclusion, the synchrotron-radiation SR-IMS is able to image molecular structure of the forage leaf tissue at an ultra-highly resolution. The advanced SR-IMS technique could provide leaf tissue four kinds of information simultaneously: tissue structure, tissue chemistry, tissue nutrients, and tissue environment of forage.

Bio-functions and molecular carbohydrate structure association study in forage with different source origins revealed using non-destructive vibrational molecular spectroscopy techniques.

Abstract
The objectives of this study were to: 1) investigate forage carbohydrate molecular structure profiles; 2) bio-functions in terms of CHO rumen degradation characteristics and hourly effective degradation ratio of N to OM (HEDN/OM), and 3) quantify interactive association between molecular structures, bio-functions and nutrient availability. The vibrational molecular spectroscopy was applied to investigate the structure feature on a molecular basis. Two sourced-origin alfalfa forages were used as modeled forages. The results showed that the carbohydrate molecular structure profiles were highly linked to the bio-functions in terms of rumen degradation characteristics and hourly effective degradation ratio. The molecular spectroscopic technique can be used to detect forage carbohydrate structure features on a molecular basis and can be used to study interactive association between forage molecular structure and bio-functions.

Vibrational microspectroscopy enables chemical characterization of single pollen grains as well as comparative analysis of plant species based on pollen ultrastructure. PLANTA 2015; 242:1237-50.

Abstract
Chemical imaging of pollen by vibrational microspectroscopy enables characterization of pollen ultrastructure, in particular phenylpropanoid components in grain wall for comparative study of extant and extinct plant species. A detailed characterization of conifer (Pinales) pollen by vibrational microspectroscopy is presented. The main problems that arise during vibrational measurements were scatter and saturation issues in Fourier transform infrared (FTIR), and fluorescence and penetration depth issues in Raman. Single pollen grains larger than approx. 15 µm can be measured by FTIR microspectroscopy using conventional light sources, while smaller grains may be measured by employing synchrotron light sources. Pollen grains that were larger than 50 µm were too thick for FTIR imaging since the grain constituents absorbed almost all infrared light. Chemical images of pollen were obtained on sectioned samples, unveiling the distribution and concentration of proteins, carbohydrates, sporopollenins and lipids within pollen substructures. The comparative analysis of pollen species revealed that, compared with other Pinales pollens, Cedrus atlantica has a higher relative amount of lipid nutrients, as well as different chemical composition of grain wall sporopollenin. The pre-processing and data analysis, namely extended multiplicative signal correction and principal component analysis, offer simple estimate of imaging spectral data and indirect estimation of physical properties of pollen. The vibrational microspectroscopy study demonstrates that detailed chemical characterization of pollen can be obtained by measurement of an individual grain and pollen ultrastructure. Measurement of phenylpropanoid components in pollen grain wall could be used, not only for the reconstruction of past environments, but for assessment of diversity of plant species as well. Therefore, analysis of extant and extinct pollen species by vibrational spectroscopies is suggested as a valuable tool in biology, ecology and palaeosciences.

Abstract
All trans-retinoic acid (ATRA) is widely used to direct the differentiation of cultured stem cells. When exposed to the pluripotent human embryonal carcinoma (EC) stem cell line, TERA2.cl.SP12, ATRA induces ectoderm differentiation and the formation of neuronal cell types. We have previously generated synthetic analogues of retinoic acid (EC23 and EC19) which also induce the differentiation of EC cells. Even though EC23 and EC19 have similar chemical structures, they have differing biochemical effects in terms of EC cell differentiation. EC23 induces neuronal differentiation in a manner similar to ATRA, whereas EC19 directs the cells to form epithelial-like derivatives. Previous MALDI-TOF MS analysis examined the response of TERA2.cl.SP12 cells after exposure to ATRA, EC23 and EC19 and further demonstrated the similarly in the effect of ATRA and EC23 activity whilst responses to EC19 were very different. In this study, we show that Fourier Transform Infrared Micro-Spectroscopy (FT-IRMS) coupled with appropriate scatter correction and multivariate analysis can be used as an effective tool to further investigate the differentiation of human pluripotent stem cells and monitor the alternative affects different retinoid compounds have on the induction of differentiation. FT-IRMS detected differences between cell populations as early as 3 days of compound treatment. Populations of cells treated with different retinoid compounds could easily be distinguished from one another during the early stages of cell differentiation. These data demonstrate that FT-IRMS technology can be used as a sensitive screening technique to monitor the status of the stem cell phenotype and progression of differentiation along alternative pathways in response to different compounds.
