Reply to Dong and Zhao: Plant stress via Raman spectroscopy

Abstract

Dong and Zhao (1) attempt to provide perspective on our use of Raman spectroscopy in plant stress studies (2). Unfortunately, their experimental criticism is incorrect and their technical suggestions won't work. The following points support these strong statements. Dong and Zhao claim that Raman spectroscopy is limited by its “poor repeatability” (1). Our experimental data speak for themselves, as shown in Fig. 1. The spectra are remarkably consistent between experiments and across species, even though the red-leaved Begonias (Fig. 1) had higher levels of anthocyanins initially. Fig. 1. Texas A&M University data are shown reproducing Raman spectra from …[↵][1]1To whom correspondence should be addressed. Email: scully{at}tamu.edu. [1]: #xref-corresp-1-1
