Boron is required for fiber growth and development in cotton ovules cultured in vitro. Incorporation of [(14)C]glucose by such fiber from supplied UDP-[(14)C]glucose into the hot alkali-insoluble fraction is rapid and linear for about 30 minutes. Incorporation of [(14)C]glucose from such substrate by fibers grown in boron-deficient ovule cultures is much less than in the case with fibers from ovules cultured with boron in the medium. Total products (alkali-soluble plus alkali-insoluble… Expand
Incorporation of UDPGlucose into Cell Wall Glucans and Lipids by Intact Cotton Fibers.
TLDR
The data supports the concept that glucan synthesis, including cellulose, as well as the synthesis of steryl glucosides, acetylated steryl glucose, and glucosyl-phosphoryl-polyprenol from externally supplied UDPglucose occurs at the plasma membrane-cell wall interface. Expand
Pyrimidine Pathway in Boron-deficient Cotton Fiber.
TLDR
A primary event of boron deficiency in cotton fiber culture is an alteration in the flow of metabolites through the pyrimidine synthesis pathway. Expand
Isolation and culture of cotton ovule epidermal protoplasts (prefiber cells) and analysis of the regenerated wall
TLDR
Analysis of a cellular fraction indicated that the majority of 14C incorporated from [14C] glucose was present in the hot-water-soluble fraction of the cells, and only 5 to 15% of the regenerated cell wall could be characterized as β-1,4-linked glucose indicative of cellulose. Expand
Isolation and culture of anucleate protoplasts from cotton fiber; assessment of viability and analysis of regenerated wall polymers
TLDR
The composition of the regenerated cell walls formed by the anucleate protoplasts was similar to the secondary cell wall synthesized by intact cotton fibers under the same culture conditions. Expand
Inhibition of trehalose breakdown increases new carbon partitioning into cellulosic biomass in Nicotiana tabacum.
TLDR
Validamycin A was used to inhibit in vivo trehalase activity in tobacco enabling the study of subsequent changes in new C partitioning into cellulosic biomass and lignin precursors, which increased foliar cellulose and starch content, decreased sucrose, and total amino acid and nitrate content, and had no effect on total protein.

Boron deficiency in cultured pine cells : quantitative studies of the interaction with ca and mg.
TLDR
A pronounced interaction between calcium, magnesium, and boron was found in growth studies with Pinus radiata cell cultures and it was found that B is, surprisingly, not bound strongly and that the affinity for Ca is two orders of magnitude stronger than for Mg. Expand
Effects of boron on growth of tomato cell suspensions
TLDR
The results indicate that B enters the tomato cells through passive transport and that a passive equilibrium exists between B concentrations in the cells and in the media. Expand
Synthesis, salvage, and catabolism of uridine nucleotides in boron-deficient squash roots.
TLDR
Results provide evidence that boron-deficient plants are not starved for uridine nucleotides collectively, and whether a particular pyrimidine nucleotide or derivative is limiting during borons deprivation remains to be examined. Expand
Development of the Cotton Fiber
TLDR
The developing cotton fibers provide a rich source of homogeneous single cells, which should be preferred for structural and biosynthetic studies of the cell wall. Expand
Plant Cell Wall Dynamics are Regulated by Intercellular Sugar Trafficking
Cellulose biosynthesis in plant cell walls is continually modified to accommodate developmental stages of the plant and to respond to environmental changes. Here we used radioactive isotopes of 11CExpand

Utilization of nucleoside diphosphate glucoses in developing cotton fibers.
TLDR
Activity for the production of two of these three presumed glucolipids increased with increasing age of fibers and incorporation of radioactivity from GDP-(14)C-glucose into hot alkali-insoluble product increased. Expand
UDP-glucose: Glucan Synthetase in Developing Cotton Fibers: I. Kinetic and Physiological Properties.
TLDR
In detached fibers, glucan synthetase activity is high at all stages of fiber development and the ability to detect enzyme activity is more dependent on fiber age, showing maximal activity between 16 and 18 days postanthesis, coincident with the time of rapid onset of secondary wall cellulose deposition.

The Influence of Boron on Starch Phosphorylase and its Significance in Translocation of Sugars in Plants.
TLDR
A hypothesis is presented which could explain why translocation of sugars in plants is increased when the element is present in sugar feeding and in C/sup 14/ carbohydrate synthesis experiments. Expand
Synthesis of Cellulose by Enzyme Preparations from the Developing Cotton Boll
TLDR
The experiments reported here demonstrate that the incorporation of radio-activity into cellulose of cotton fibres in vitro and other polysaccharides were formed by the same cell-free enzyme system are brought about by enzymes isolated from the developing cotton boll. Expand
Biosynthesis of Insoluble Glucans From Uridine-Diphosphate-d-Glucose With Enzyme Preparations From Phaseolus aureus and Lupinus albus.
TLDR
Careful examination of the products of degradation of the polymers produced by various enzymic preparations showed that beta-1-->3)-glucans are produced, and no evidence was obtained for any measurable amount of beta-(1-->4)-d-glucose linkages. Expand
Changes in biochemical composition of the cell wall of the cotton fiber during development.
TLDR
Comparison of results on total cell wall composition and linkages of sugars as determined by a preliminary methylation analysis of unfractionated fiber walls indicates that the primary cell wall of cotton fibers is similar to that of primary cell walls of other dicotyledons and of gymnosperms as reported in the literature. Expand
UDP-glucose: Glucan Synthetase in Developing Cotton Fibers: II. Structure of the Reaction Product.
TLDR
The results of acetic and nitric acid digestion, enzyme digestion, total acid hydrolyses, periodate oxidation, partial acid hydroleyses, and methylation analyses all support the conclusion that the product of the glucan synthetase produced under all three assay conditions is a linear beta-(1-->3)-glucan.

Interaction of boron with components of nucleic Acid metabolism in cotton ovules cultured in vitro.
TLDR
Growth inhibition by most nucleoside base analogs tested, actinomycin D, fluorodeoxyuridine, and ethidium bromide, indicates that boron deficiency symptoms are not related to a reduction in nucleic acid biosynthesis, and a discussion of the possibility that borron deficiency causes reduced synthesis of UDP-glucose is presented.

Labeling of the Plasma Membrane of Pea Cells by a Surface-localized Glucan Synthetase.
TLDR
Evidence is given that this incorporation does not result from breakdown of UDP-glucose and utilization of the resultant free glucose, and that the incorporation most likely takes place at the cell surface, leading to a specific labeling of the plasma membrane. Expand
Biosynthesis of Alkali Insoluble Polysaccharide from UDP-d-Glucose with Particulate Enzyme Preparations from Phaseolus aureus.
TLDR
None of the glycosyl nucleotides containing bases other than guanine or uracil served as substrate for the production of alkali insoluble polysaccharide with this enzyme system, and dUDP-d-glucose could also not serve as substrate. Expand
