Abstract

Fourier Transform InfraRed (FTIR) spectroscopy is a powerful and rapid technique for analysing cell wall components and putative cross-links, which is able to non-destructively recognize polymers and functional groups and provide abundant information about their in muro organization. FTIR spectroscopy has been reported to be a useful tool for monitoring cell wall changes occurring in muro as a result of various factors, such as growth and development processes, mutations or biotic and abiotic stresses. This mini-review examines the use of FTIR spectroscopy in conjunction with multivariate analyses to monitor cell wall changes related to (1) the exposure of diverse plant materials to cellulose biosynthesis inhibitors (CBIs), and (2) the habituation/dehabituation of plant cell cultures to this kind of herbicides. The spectra analyses show differences not only regarding the inhibitor, but also regarding how long cells have been growing in its presence.

摘要

傅里叶变换红外(FTIR)光谱学是一种强大而快速的分析细胞壁成分和假定交联的技术,能够非破坏性地识别聚合物和官能团,并提供有关其在细胞壁内组织的丰富信息。已经报道 FTIR 光谱学是一种有用的工具,可用于监测由于各种因素(如生长和发育过程、突变或生物和非生物胁迫)而在细胞壁内发生的变化。本综述检查了使用 FTIR 光谱学结合多元分析来监测与以下方面相关的细胞壁变化:(1)不同植物材料暴露于纤维素生物合成抑制剂(CBIs),以及(2)植物细胞培养物对这种除草剂的习惯/去习惯。光谱分析不仅显示了抑制剂的差异,还显示了细胞在其存在下生长的时间长短。
