A new methionine-rich seed storage protein from maize.
The endosperm of maize (Zea mays) seeds contains severa1 classes of alcohol-soluble storage proteins called zeins, which together make up nearly 50% of the total seed protein content. The abundance of the zeins and their low content of the essential amino acid Lys is responsible for the relatively poor nutritional quality of maize protein. However, zeins rich in other nutritionally important am...
متن کاملSeed-Specific Expression of a Lysine-Rich Protein Gene, GhLRP, from Cotton Significantly Increases the Lysine Content in Maize Seeds
Maize seed storage proteins are a major source of human and livestock consumption. However, these proteins have poor nutritional value, because they are deficient in lysine and tryptophan. Much research has been done to elevate the lysine content by reducing zein content or regulating the activities of key enzymes in lysine metabolism. Using the naturally lysine-rich protein genes, sb401 and SB...
متن کاملMaize Seed Storage Mycoflora in Pakistan and Its Chemical Control
Eleven seed-borne fungal species were recorded in the 18 maize seed samples collected from 6 maize growing districts of Punjab and Khyber-Pakhtoonkhwa, Pakistan. Aspergillus flavus, A. niger and Fusarium moniliforme were the most prevalent species with the incidence range up to 94, 62 & 43%, respectively. Maximum number of fungal species i.e., 10 was observed from Okara, Sahiwal and Nowshehra, ...
متن کاملDuplication-dependent CG suppression of the seed storage protein genes of maize.
This study investigates the prevalence of CG and CNG suppression in single- vs. multicopy DNA regions of the maize genome. The analysis includes the single- and multicopy seed storage proteins (zeins), the miniature inverted-repeat transposable elements (MITEs), and long terminal repeat (LTR) retrotransposons. Zein genes are clustered on specific chromosomal regions, whereas MITEs and LTRs are ...
متن کاملLysine rich 18 kDa storage polypeptide front buckwheat seed
Lysine, which is a limited amino acid in cereals, has a remarkably high content in buckwheat seed proteins. We have analyzed the pattern of 14C lysine incorporation into buckwheat seed polypeptides during the mid-maturation stage of seed development. Based on this approach, an 18 kDa polypeptide could be assigned as being lysine rich.
