Total proteins from pericarp tissue of different chronological ages from normally ripening tomato (Lycopersicon esculentum Mill. cv Rutgers) fruits and from fruits of the isogenic ripening-impaired mutants rin, nor, and Nr were extracted and separated by sodium dodecylsulfate-polyacrylamide gel electrophoresis. Analysis of the stained bands revealed increases in 5 polypeptides (94, 44, 34, 20, ...

Cultivated pepper (Capsicum annuum) is a phenotypically diverse species grown throughout the world. Wild and landrace peppers are typically small-fruited and pungent, but contain many important traits such as insect and disease resistance. Cultivated peppers vary dramatically in size, shape, pungency, and color, and often lack resistance traits. Fruit characteristics (e.g. shape and pericarp th...

BACKGROUND The pericarp color1 (p1) gene encodes for a myb-homologous protein that regulates the biosynthesis of brick-red flavonoid pigments called phlobahpenes. The pattern of pigmentation on the pericarp and cob glumes depends upon the allelic constitution at the p1 locus. p1 alleles have unique gene structure and copy number which have been proposed to influence the epigenetic regulation of...

The temporal and spatial variations of phoxim residue in apples were studied. The insecticide phoxim was applied by spraying according to the recommended dosage. The phoxim residues in different parts of apple were extracted with acetonitrile, purified by primary secondary amine (PSA) and C18 filler, and then determined by gel permeation chromatography-gas chromatograph mass spectrometer (GPC-G...

OBJECTIVES This study aimed to develop drugs from natural sources to overcome the side effects of many of synthetic drugs. Methanol extracts of both pericarp and seeds of Pleiogynium solandri were used to investigate antioxidant, hepatoprotective, and renal function protective, analgesic, and anti-inflammatory effects and to determine the chemical composition of the extract responsible for bioa...

Sucrose metabolism and the role of sucrose synthase were investigated in the fruit tissues (pericarp, perisperm, and endosperm) of Coffea arabica during development. Acid invertase, sucrose phosphate synthase, and sucrose synthase activities were monitored and compared with the levels of sucrose and reducing sugars. Among these enzymes, sucrose synthase showed the highest activities during the ...

The objective of this study is to determine the tyrosinase inhibition and antibacterial activities against the pathogenic bacteria in the oral cavity of the mangosteen pericarp extract. The results showed that the mangosteen pericarp extract inhibited the tyrosinase enzyme at IC50 = 67 ng/ml. Furthermore, the mangosteen pericarp extract also exhibited the antibacterial activities against the pa...

OLORLESS pericarp and cob is one of the least frequent mutant phenotypes C among the offspring of maize plants carrying the somatically unstable variegated pericarp allele, PV. BRAWN (1956) , for example, found only eight mutations to colorless pericarp and cob in contrast to 125 to red pericarp and cob(P") among 4575 offspring from the mating homozygous variegated times standard colorless (P""...

Condensed tannin is a ubiquitous polyphenol in plants that possesses substantial antioxidant capacity. In this study, we have investigated the polyphenol extraction recovery and 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity of the extracted polyphenol after litchi pericarp is treated with Aspergillus awamori, Aspergillus sojae or Aspergillus oryzae. We have further explored the activ...

Cnr (colorless non-ripening) is a pleiotropic tomato (Lycopersicon esculentum) fruit ripening mutant with altered tissue properties including weaker cell-to-cell contacts in the pericarp (A.J. Thompson, M. Tor, C.S. Barry, J. Vrebalov, C. Orfila, M.C. Jarvis, J.J. Giovannoni, D. Grierson, G.B. Seymour [1999] Plant Physiol 120: 383-390). Whereas the genetic basis of the Cnr mutation is being ide...
