Adult male rats were fed on diets containing 100 g dietary fibre/kg either as alpha-cellulose or wheat bran or the pericarp-seed coat or aleurone layers prepared from that bran by sequential milling and air elutriation and electrostatic separation. After 10 d, concentrations of total volatile fatty acids (VFA) in caecal fluid were significantly different between groups and fell in the order: al...

Enzymically active cell wall from ripe tomato (Lycopersicon esculentum Mill.) fruit pericarp release uronic acids through the action of wall-bound polygalacturonase. The potential involvement of products of wall hydrolysis in the induction of ethylene synthesis during tomato ripening was investigated by vacuum infiltrating preclimacteric (green) fruit with solutions containing pectin fragments ...

Wheat (Triticum aestivum L.) cultivars possessing purple grain arethought to be more nutritious because of high anthocyanin contents in the pericarp. Comparative transcriptome analysis of purple (cv Gy115) and white pericarps was carried out using next-generation sequencing technology. There were 23,642 unigenes significantly differentially expressed in the purple and white pericarps, including...

Tandemly repeated endogenous genes are common in plants, but their transcriptional regulation is not well characterized. In maize, the P1-wr allele of pericarp color1 is composed of multiple copies arranged in a head-to-tail fashion. P1-wr confers a white kernel pericarp and red cob glume pigment phenotype that is stably inherited over generations. To understand the molecular mechanisms that re...

The present work was carried out to evaluate the ap plication of delayed ripening (employing controlled atmo sphere (CA) storage) to minimize or alleviate the development of the ripening disorder known as internal bruising. Tomato (Lycopersicon esculentum Mill.) fruits, cv. Solimar, were har vested in Bradenton (Florida) at the mature-green stage and gassed with 100 mLL1 of ethylene at 20 C to ...

The pericarp consist in the transformed wall of the ovary that covers the seed and acts as a protection for the embryo and endosperm. It takes the place of the seed coats or integuments in the ordinary seeds, which in maize are reduced to unnoticeable remnants in the mature kernel. A thin, suberized nucellar membrane derived from the outer epidermal wall of the nucellus persists as a continuous...

THE postfertilization development of the ovary of the hazel flower results in the formation from the outer integument of the ovule of a thin fibrous seed coat closely adherent to the embryo and from the ovary wall of a hard, lignified pericarp which is quite free from the seed coat at the time when the fruit is ripe. The work recorded in this paper was done on the pericarp of the hazel fruit. T...

A surface sampling method for analysis of pesticide residues in pome fruit was studied by layer-by-layer scan from pericarp to kernel. Phoxim residues of apples, pears and papayas was determined by GC-MS, respectively, in core, different layers of pulp, peel ,as well as the whole fruit. Phoxim residue content was decreased when depth of the layer increased. It was inferred from experimental dat...

to investigate the genotypic and phenotypic relationship between characteristics affecting tomato fruit weights, eleven tomato lines were compared in a rcb design with three replications. the anova showed that the difference among lines was significant for all characteristics. there was a significant phenotypic and genotypic correlations between fruit weight and most of the characteristics. the...

Rc is a domestication-related gene required for red pericarp in rice (Oryza sativa). The red grain color is ubiquitous among the wild ancestors of O. sativa, in which it is closely associated with seed shattering and dormancy. Rc encodes a basic helix-loop-helix (bHLH) protein that was fine-mapped to an 18.5-kb region on rice chromosome 7 using a cross between Oryza rufipogon (red pericarp) and...
