Two new methods, one of broad specificity and the other of
narrow specificity, were developed for the identification of
agrobacteria. The former method was based on ribosomal antigens
that were common to members of the closely related Agrobacterium
and Rhizobium genera. Antisera to unwashed 50 S ribosomal subunits
from five...
Involvement has been defined and researched by many student affairs professionals and theorists over the past 40 plus years. While many studies have researched the relationship between involvement and a student's academic success, little research has been done that explores what involvement means to them, and the motivations and factors...
Crown gall was found in numerous pecan orchards in Georgia. In
some instances, 60% of the trees were diseased. Galled trees were
less vigorous than noninfected trees. Among the pathogenic
Agrobacterium strains isolated from 18 galled trees from six
counties, biovar 1 strains predominated and most were sensitive to
agrocin...
In 2013, a large upper-ocean thermal anomaly formed in the Gulf of Alaska (GOA) with sea surface temperatures (SSTs) warmer than 4 degrees Celsius above the climatological norm. This warm anomaly persisted for the next three years and has been linked to downstream effects on North American climate and negative...
Tomato seedlings were used to assay the population of A.
tumefaciens in artificially contaminated soil. Aqueous soil suspensions
were applied directly to the wounded stem. The bioassay was
used because not all pathologically important physiological strains
of A. tumefaciens would grow on any of the selective media available.
This method...
A study was made of compounds produced by Agrobacterium radiobacter
strain 84 that are inhibitory to some pathogenic strains of A.
tumefaciens. Agrocins (inhibitory compounds) were partially purified
from large volumes of A. radiobacter strain 84 culture supernatants to
determine (i) if more than one agrocin is produced, (ii) if...
