The timing of harvest is a major factor affecting seed quality in soybean, particularly in Midsouthern USA, when rain during harvest period is not uncommon. The objective of this research was to evaluate the effects of time of harvest on soybean seed quality (seed composition, germination, seed coat boron, and lignin) in high germinability (HG) breeding lines (50% exotic) developed under high h...

UNLABELLED Icosahedral virus assembly requires a series of concerted and highly specific protein-protein interactions to produce a proper capsid. In bacteriophage P22, only coat protein (gp5) and scaffolding protein (gp8) are needed to assemble a procapsid-like particle, both in vivo and in vitro. In scaffolding protein's coat binding domain, residue R293 is required for procapsid assembly, whi...

Striped jack nervous necrosis virus (SJNNV), a fish nodavirus, is the causative agent of viral nervous necrosis in marine fishes. The fish nodaviruses are divided into four different genotypes based on the nucleotide sequence of the coat protein gene. In the present study, partial coat protein genes of fish nodaviruses were expressed. This allowed the serological relationship among the differen...

An unusual and distinguishing feature of alfalfa mosaic virus (AMV) and ilarviruses such as tobacco streak virus (TSV) is that the viral coat protein is required to activate the early stages of viral RNA replication, a phenomenon known as genome activation. AMV-TSV coat protein homology is limited; however, they are functionally interchangeable in activating virus replication. For example, TSV ...

Rice tungro bacilliform virus (RTBV) is a plant pararetrovirus and a member of the Caulimoviridae family and closely related to viruses in the Badnavirus genus. The coat protein of RTBV is part of the large polyprotein encoded by open reading frame 3 (ORF3). ORF3 of an RTBV isolate from Malaysia was sequenced (accession no. AF076470) and compared with published sequences for the region that enc...

Alfalfa mosaic virus (AlMV) coat protein is involved in systemic infection of host plants, and a specific mutation in this gene prevents the virus from moving into the upper uninoculated leaves. The coat protein also is required for different viral functions during early and late infection. To study the role of the coat protein in long-distance movement of AlMV independent of other vital functi...

Species from the genus Bacillus have the ability to form endospores, dormant cellular forms that are able to survive heat and acid preservation techniques commonly used in the food industry. Resistance characteristics of spores towards various environmental stresses are in part attributed to their coat proteins. Previously, 70 proteins have been assigned to the spore coat of Bacillus subtilis u...

Ribosome releasing factor (RR factor) releases ribosomes from mRNA at the termination codon in Escherichia coli. In the absence of this factor, polypeptides with molecular weights very close to the molecular weight of bacteriophage R17 coat protein were synthesized in vitro under the direction of a mutant R17 phage RNA having an amber mutation at codon 7 of the coat cistron. The major coat-prot...
