Abstract:
Change in climate means that there is more drought especially in regions (arid). Crop productivity mostly effected by drought stress. Despite huge data on drought stress in crops, there is still many ambigiuties concerning the responses of cereal crops at molecular level under drought. Particularly, if identify traits that are novel, we can breed crops for drought stress tolerance. In current work, Fourier Transform Infrared (FTIR) was used to explore the response of maize hybrids to drought at molecular level. Objective was to check whether FTIR can be used as monitoring technique to assess drought responces or not. Maize (Zea mays. L) seeds of both hybrids (3366, 6619) were grown for two weeks in a wirenet house then drought was imposed by withholding water for up to two weeks. FTIR spectroscopy was performed by using dried samples. Principal component analysis (PCA) indicated that water deficit elicited changes in spectra of FTIR within the in drought sensitive variety (6619) and drought tolerant variety (3366). Under drought, the intensities of the absorption bands were changed in both varieties. PCA loadings confirmed that the signals to the changes were lipids, amides and carbohydrates, respectively. This study shows that FTIR spectroscopy can provide valuable insights into drought responses of maize hybrids and maybe useful for identifying novel traits for drought tolerance.
