Structural Changes Associated with Resistance of Soybean to Heterodera glycines.
Subcellular responses to infection by Race 3 of Heterodera glycines in susceptible ('Lee') and resistant ('Forrest' and 'Bedford') soybean cultivars were compared and differences in resistant responses reflect a difference in genetic composition of the soy bean cultivars tested.
Saccharomyces cerevisiae contains two functional citrate synthase genes
The isolation, by an immunological method, of a second nuclear gene encoding citrate synthase (CIT2) is reported, which showed that disruption of both genes in the yeast genome was necessary to produce classical citate synthase-deficient phenotypes: glutamate auxotrophy and poor growth on rich medium containing lactate, a nonfermentable carbon source.
Growth Inhibition and Root Ultrastructure of Cucumber Seedlings Exposed to Allelochemicals from Rye (Secale cereale)
Changes in cellular ultrastructure indicated that BOA and DIBOA reduced root growth by disrupting lipid metabolism, reducing protein synthesis, and reducing transport or secretory capabilities.
Textural changes in mushrooms (Agaricus bisporus) associated with tissue ultrastructure and composition
M Mushroom softening paralleled expansion of intercellular space at the pilei surface, hyphae shrinkage, central vacuole disruption, and loss of proteins and polysaccharides, while toughening was associated with increased chitin content.
5′-Terminal Deletions Occur in Coxsackievirus B3 during Replication in Murine Hearts and Cardiac Myocyte Cultures and Correlate with Encapsidation of Negative-Strand Viral RNA
A naturally occurring genomic alteration to an enteroviral genome associated with long-term viral persistence is described, demonstrated that CVB3/TD virus strains replicate and persist in vivo.

O-xylene was transformed to a metabolite in the presence of toluene but did not serve as the sole source of carbon for growth of strain T1, which was distinct from other bacteria that oxidize toLUene anaerobically, but it may utilize a similar biochemical pathway of oxidation.
Persistent coxsackievirus infection: enterovirus persistence in chronic myocarditis and dilated cardiomyopathy.
Factors that control the extent of cardiac infection with terminally deleted enteroviruses and the relative roles of continued immune response of the virus vs viral modification of cardiac function need to be measured to find effective therapies for the human disease.
Pectinolytic enzymes from actinomycetes for the degumming of ramie bast fibers.

Treatment of ramie bast fibers with crude enzyme preparations from a selection of strains showed a good correlation between the pectate lyase activity applied and the degumming effect, resulting in good separation of the bast fibers.
Infection of Phaseolus vulgaris by bean golden mosaic virus: ultrastructural aspects.
Simulation of apparent infection rate to predict severity of soybean rust using a fuzzy logic system.
It is suggested that a model could be developed to determine apparent infection rate and an initial value of disease severity in advance using forecasted weather data, which would provide accurate prediction of severity of soybean rust before the start of a season.
