Cereal storage

In monocotyledonous plants, including all the cereals, storage proteins are found mainly in the endosperm. The major storage compounds are carbohydrates rather...

Pascual Villalobos (2003) found the potential of plant essential oils against stored-product beetle pests. Coriander oil (10 pi) showed activity against the bruchid Callosobruchus maculates, the cereal storage pest. 

Fig. 4. Schematic structure of y-gliadin. Modified from Kreis et al. (1985). Regions A, B, and C are found in other related cereal storage proteins. The disulphide pairing is inferred from the homology of the C-terminal domain to cereal seed inhibitions of amylase.

Another major use of computers for HPLC data should be varietal identification (see later). Qualitatively, cereal storage proteins vary little within genotypes but significantly among different varieties, so they provide characteristic fingerprints. Varietal identification can be automated by computer comparisons with stored standard data. Scanlon et al. [80] showed that normalization of peak retention times provided sufficient precision for cultivar identification. Resulting data based on peak heights and times could be used in an automated library search to identify wheat varieties [81].

In the quest to find other plants that are suitable as bioreactors, various monocoty-ledonous and dicotyledonous species have been tested. These include corn [16], rice and wheat [17], alfalfa [18], potato [19, 20], oilseed rape [21], pea [22], tomato [23] and soybean [24]. The major advantage of cereal crops is that recombinant proteins can be directed to accumulate in seeds, which are evolutionar specialized for storage and thus protect proteins from proteolytic degradation. Recombinant proteins are reported to remain stable in seeds for up to five months at room temperature [17] and for at least three years at refrigerator temperature without significant loss of activity [25]. In addition, the seed proteome is less complex than the leaf proteome, which makes purification quicker and more economical [26].

These organelles occur in the endosperm of cereal grains and their structures are tissue specific. They are about 2-5 im in diameter and often contain globoid and occasionally crystalloid inclusions. Prolamin accumulates in small or large spherical bodies. Crystalline protein bodies are the sites of accumulation of nonprolamin storage proteins.
