Overexpression of a Gene Involved in Phytic Acid Biosynthesis Substantially Increases Phytic Acid and Total Phosphorus in Rice Seeds.
The manipulation of seed phosphorus is important for seedling growth and environmental P sustainability in agriculture. The mechanism of regulating P content in seed, however, is poorly understood. To study regulation of total P, we focused on phytic acid (inositol hexakisphosphate; InsP₆) biosynthesis-related genes, as InsP₆ is a major storage form of P in seeds. The rice (Oryza sativa L.) low...
متن کاملPhytic acid prevents oxidative stress in seeds: evidence from a maize (Zea mays L.) low phytic acid mutant.
A maize mutant defective in the synthesis of phytic acid during seed maturation was used as a tool to study the consequences of the lack of this important reserve substance on seed survival. Data on germinability, free iron level, free radical relative abundance, protein carbonylation level, damage to DNA, degree of lipid peroxidation, alpha- and gamma-tocopherol amount and antioxidant capacity...

Cereal Chem. 82(5):5 17-522 Phytie acid iins'o-inositolI .2.3.4.5.6-hexaki.sphosphate) is the most abundant lorni of phosphorus (P) in cereal grains and is important to grain nutritional qualit y . In [nature rice ( Orv:a rota L) erains, the bulk Of phytic acid P is found in the germ and aleurone layer. deposited primarily as a mixed K/Mg salt. Phosphorus components and minerals were measured i...
متن کاملRadioactively Labelled Phytic Acid from Maturing Seeds of Sinapis alba
Maturing seeds of Sinapis alba were incubated with D-[U-14C]glucose, sodium [l-14C]acetate or m>>0-[U-14C]inositol in order to prepare radioactively labelled phytic acid with high specific activity. Although each substrate was utilized for the biosynthesis of phytic acid, maximum incorporation of radioactivity into phytic acid was found with rayo-inositol. Radiochemical purity of the [U-14C]phy...
متن کاملHormonal Regulation and Expression Profiles of Wheat Genes Involved during Phytic Acid Biosynthesis Pathway
Phytic acid (PA) biosynthesis pathway genes were reported from multiple crop species. PA accumulation was enhanced during grain filling and at that time, hormones like Abscisic acid (ABA) and Gibberellic acid (GA₃) interplay to control the process of seed development. Regulation of wheat PA pathway genes has not yet been reported in seeds. In an attempt to find the clues for the regulation by h...
