Biology of mudplantain (Heteranthera reniformis Ruiz et Pavon) and its control in flooded rice

Creator:: Gabela, Francisco Jose A.
Abstract:: In CIAT, Centro Internacional de Agricultura Tropical, located in Palmira, Colombia, a series of experiments were conducted to study the biology and control of mudplantain (Heteranthera reniformis Ruiz et Pavon), a member of Pontederiaceae family. Mudplantain is a perennial aquatic plant which reproduces by both seeds and stolons. It is...

Physical structure and reconstitution of chromatin core particles

Creator:: Tatchell, Kelly George
Abstract:: The nucleosome appears to be the basic structural unit of the eukaryotic chromosome. The usual nucleosome preparation, isolated from a micrococcal nuclease digest of nuclei, is heterogenous in DNA length and protein composition with some particles containing spacer DNA and associated protein. This heterogeneity complicated physical and reconstitution studies. As...

Hydrogen-stimulated CO₂ fixation and coordinate derepression of hydrogenase and ribulosebisphosphate carboxylase in a H₂-uptake positive strain of Rhizobium japonicum

Creator:: Simpson, Frank Berry
Abstract:: H₂-uptake positive strains (122 DES and SR) and H₂-uptake negative strains SR2 and SR3 of Rhizobium japonicum were examined for ribulosebisphosphate (RuBP) carboxylase and H₂-uptake activities during growth conditions which induced formation of the hydrogenase system. The rate of ¹⁴CO₂ uptake by hydrogenase-induced cells was about six times greater in...

Ti plasmid coded protein in Agrobacterium tumefaciens

Creator:: Engelgau, Michael Maurice
Abstract:: Agrobacterium tumefaciens is a plant pathogenic bacteria which incites crown gall tumors. Although virulence has been associated with a 97-156 Mdalton "tumor-inducing" (Ti) plasmid, few potential plasmid gene products have been identified. The objective of this study was to identify plasmid-coded gene products through a comparison of protein fingerprints of...

Cell wall formation in Fucus zygotes : cellulose synthesis and deposition after fertilization

Creator:: Stevens, Patricia T.
Abstract:: Under defined cultural conditions, large populations of zygotes of the brown algae Fucus vesiculosus L. and F. distichus L. Powell synchronously form a cell wall shortly after fertilization. Intact cell walls, free of cytoplasm and maintaining shape properties of early stages of embryo development, have been isolated from these zygotes....

Physical studies of the yeast inner histones

Creator:: Mardian, James Kenneth Walker
Abstract:: In this work, the four yeast inner histones were prepared by the use of consecutive slab gel fractionation. The use of this technique allowed the first complete fractionation and rigorous identification of the four yeast inner histones, and made possible a study of their complexing behavior. Variants and adjuncts of...

Textural changes in broccoli and carrots cooked by microwave energy

Creator:: Schrumpf, Elaine
Abstract:: Carrots cooked by microwaves were judged less tender in both the core and external flesh area than those cooked by conventional boiling. Broccoli cooked by microwaves was less tender in the external layer but softer in the central flesh than that cooked conventionally. Cooking methods made essentially no difference in...

Measuring cultural competence in counselor-trainees : the development of an assessment process

Creator:: Tomine, Satsuki Ina
Abstract:: Statement of the Problem The primary purpose of this investigation was to determine if a valid and reliable assessment instrument could be developed to measure the cultural competence of counselor trainees. Hypotheses Five hypotheses were generated to establish the reliability and validity of the instrument. The instrument consisted of two...
