Pea seed-borne mosaic potyvirus pathotype 1 (PSbMV-P1) has the ability to infect most genotypes of Pisum sativum. The exception are those genotypes that are homozygous recessive for the sbm-1 gene. The life cycle of PSbMV pathotype 4 (PSbMV-P4) is unaffected by the sbm-1/sbm-1 genotype. Infectious clones of Pl-P4 recombinants were...
Polyclonal antisera were raised against isolates of bean
common mosaic virus (BCMV) and bean common mosaic necrosis
virus (BCMNV) using conventional serological methods.
Infected tissues containing, respectively, 22 recognized BCMV
and BCMNV isolates were tested against the two antisera by
antigen-coated plate (ACP) ELISA and double antibody sandwich
(DAS) ELISA....
Biological, serological, and molecular characteristics
of the P4 pathotype of pea seedborne mosaic potyvirus
(PSbMV) were investigated. The characterization allowed P4
to be differentiated from other pathotypes of the same
virus.
P4 was distinguished from P1 on the basis of host
symptomatology. It induced varied, but often distinctive
symptoms in...
The nutritive values of two fishery by-products, i.e. fish
protein hydrolysate (FPH) and liquefied fish (LF), were studied.
Three trials using Hubbard broilers, and Yorkshire pigs (starter
and grower phase) were conducted. The FPH was used in the broiler
trial and LF in the swine grower trial as supplemental protein...
A sensitive assay for the analysis of contaminating segments
in pseudorecombinants constructed from a seed-transmissible (CVM-Pg)
and a non-seed-transmissible (CMV-Le) strain of cucumber mosaic
virus was developed using partial RNase T₁ digestion. Isolated
genomic RNA segments produced unique digestion patterns when 3'-
end labeled, treated with RNase T₁, and subjected...
A survey of major bean (Phaseolus vulgaris) breeding programs and
seed producing areas in Idaho, Washington, and Oregon was conducted to
determine the occurrence of cucumber mosaic virus (CMV), recently reported
to be seedborne in beans. Some 259 plants, sampled from breeding
lines of diverse germplasm, were found by enzyme-linked...
The purpose of this study is to provide a systematic method to
analyze relationships between inputs, technology, and market structure
of an industry, and marketing activities among countries in general
and to develop an economic analysis of trade flow of the hardwood
plywood industry in the Far East exporting countries:...
