CCLINTOCK (1956) suggested that a transposable element in maize moves Mfrom the donor site to a different recipient site on the chromosome during the mitotic reduplication process. GREENBLATT and BRINK (1962, 1963) and GREENBLATT (1966) were able to offer experimental support for this idea, and further, developed a working hypothesis of a mechanism of the element's movement. Since the evidence ...
Pericarp browning occurs widely in postharvest pomegranate fruit, but little is known about its mechanism. In this study, ‘Baiyushizi’, a browning-sensitive cultivar, was used to investigate the physiological and genetic changes during pericarp browning. The index (BI) increased greatly after 3 d storage at room temperature, and, consequently, fruit appearance became unattractive 6 d. increasin...
The intracellular location of ADP-glucose pyrophosphorylase (AGP) in developing pericarp of tomato (Lycopersicon esculentum Mill) has been investigated by immunolocalization. With the use of a highly specific anti-tomato fruit AGP antibody, the enzyme was localized in cytoplasm as well as plastids at both the light and electron microscope levels. The immunogold particles in plastids were locali...
Corn hulls are composed of two major layers: the outer layer, the pericarp, is made up of non-living cell walls, and an inner layer, the aleurone, consists of a single layer of living cells, surrounded by thick cell walls. Dissected pure pericarp and aleurone fractions were ground and extracted with hexane and the yields and compositions of the resulting oils were examined. This study revealed ...
The relationship of respiration and growth of seed, pericarp tissue and whole fruit of snap beans (Phaseolus vulgaris L.) was studied. The whole fruit exhibited an apparent climacteric type of respiration pattern. This pattern resulted from an increase in CO(2) production by the enlarging seed followed by a rapid decrease in CO(2) evolution by the pericarp tissue, and the pattern was not associ...
A model of Modulator movement (Greenblatt 1968) from one chromosomal site to another requires that all movements produce potential twin mutations within the affected cell lineage. From this model the prediction would be that (1) untwinned red and untwinned light-variegated sectors within the pericarp of medium-variegated maize must occur in equal frequency even though partners become lost, duri...
A kernel of popping corn consists of a hard outer shell called the pericarp which is impermeable to moisture and a dense center filled with starch, water and some oil[8]. As the kernel is heated, internal pressure rises to approximately 135 psi, at which point the pericarp bursts. The steam and starch expands to a foam which rapidly cools forming the popcorn. Variations in the strength of the p...
conclusions ethanol extracts of p. granatum (pericarp, leaves, flowers, seeds) have antibacterial effects against p. haemolytica which has shown resistance to all studied antibiotics. background continuous researches on drugs that solve the problem of growing number of resistant bacteria are important. objectives this research aims to investigate the effectiveness of anti-bacterial properties s...
Objective(s) The role of Elaeagnus angustifolia fruit as an analgesic agent in acute pain has been proved earlier. In this study, the effects of aqueous extracts of three parts of this fruit (pericarp, medulla and seed) on chronic pain were investigated in mice. Materials and Methods A partial nerve injury was made using a tight ligature around the sciatic nerve, then doses (0.5, 1, 1.5 g/kg...
