Isolation of Multiple cDNAs Encoding the Vacuolar H+-ATPase Subunit B from Developing Cotton (Gossypium hirsutum L.) Ovules

A cDNA encoding ribosomal protein S4e from cotton (Gossypium hirsutum L.).

Ribosomes are complex ribonucleoprotein structures that function as the machinery for synthesizing proteins needed for the maintenance, growth, development, and reproduction of cells. During the biogenesis of these structures, ribosomal precursors, i.e. ribonucleoprotein particles, are formed by the assembly of rRNA and ribosomal proteins in the nucleolus. These particles are processed to matur...

A putative lplant homolog of the yeast P - l , 3 - glucan synthase subunit FKSI from ' cotton ( Gossypium hirsutum L . ) fibers

A novel plant gene CFLl was cloned from cotton (GossJPium hirsutum L.) fibers by expressed se­ quence tag (EST) database searching and 5'-RACE (rapid amplification of eDNA ends). This gene shows sequence homology with FKSl which has been identified as the putative catalytic subunit of the yeast fi-1,3-glucan syn­ thase. It encodes a protein (CFLlp) of 219 kDa with 13 deduced transmembrane helic...

Infraspecific DNA methylation polymorphism in cotton (Gossypium hirsutum L.).

Cytosine methylation is important in the epigenetic regulation of gene expression and development in plants and has been implicated in silencing duplicate genes after polyploid formation in several plant groups. Relatively little information exists, however, on levels and patterns of methylation polymorphism (MP) at homologous loci within species. Here we explored the levels and patterns of met...

Effect of Kinetin on Multiple Shoot Induction in Cotton (Gossypium hirsutum L.) cv. NIAB-999

Boron Deficiency in Unfertilized Cotton (Gossypium hirsutum) Ovules Grown in Vitro.

Boron deficiency and phytohormone interactions have been studied in unfertilized cotton (Gossypium hirsutum) ovules grown in vitro. Such ovules required exogenous indoleacetic acid and/or gibberellic acid for fiber elongation. Boron also was required for maintenance of fiber elongation and normal morphogenesis throughout 14 days of culture. The amount of exogenous boron necessary for maximum fi...
