Abstract
The main storage components of the maize endosperm are starch, proteins and lipids. Starch and proteins are
heterogeneously deposited, leading to the formation of vitreous and floury regions at the periphery and at the centre of the
endosperm. The vitreous/floury mass ratio is a key physical parameter of maize end-uses for the food, feed and non-food
sectors, as well as for the resistance of seeds to environmental aggressions. To improve maize breeding for
vitreousness, one of the main issues is to finely delineate the molecular and physicochemical mechanisms associated with
the formation of endosperm texture. In this context, we use scanning transmission X-ray microscopy at the C K-edge on
maize endosperm resin-embedded ultrathin sections. The combination of local near edge X-ray absorption fine structure
(NEXAFS) spectroscopy and high-resolution images enable us to achieve a quantitative fine description of the spatial
distribution of the main components within the endosperm.
期刊介绍：
JSI—Journal of Spectral Imaging is the first journal to bring together current research from the diverse research areas of spectral, hyperspectral and chemical imaging as well as related areas such as remote sensing, chemometrics, data mining and data handling for spectral image data. We believe all those working in Spectral Imaging can benefit from the knowledge of others even in widely different fields. We welcome original research papers, letters, review articles, tutorial papers, short communications and technical notes.
