Angular leaf spot: a disease caused by the fungus Phaeoisariopsis griseola (Sacc.) Ferraris on Phaseolus vulgaris L.
TLDR
Although the Pg –bean pathosystem is complex, continued basic and applied research should provide answers to solve many of the problems encountered by bean growers.
Molecular cloning and characterization of a sym plasmid locus that regulates cultivar‐specific nodulation of soybean by Rhizobium fredii USDA257
Rhizobium fredii strain USDA257 produces nitrogen‐fixing nodules on primitive soybean cultivars such as Peking but fails to nodulate agronomically improved cultivars such as McCall. Transposonmutant
Inter simple sequence repeat (ISSR) markers as a tool for the assessment of both genetic diversity and gene pool origin in common bean (Phaseolus vulgaris L.)
TLDR
It appears that ISSR are better tools than RAPD to identify beans by gene pool of origin though they did not revealed as many differences between individuals as RAPDs.
Genetic Diversity among Wild Common Beans from Northwestern Argentina Based on Morpho-agronomic and RAPD Data
The genetic diversity among 10 wild populations of common bean Phaseolusvulgaris var. aborigineus was analyzed by means of RAPD markers and morpho-agronomic data. The study was performed on
Pathogenic and molecular variability among isolates of Pyrenophora tritici-repentis, causal agent of tan spot of wheat in Argentina
TLDR
Results indicate that P. tritici-repentis on wheat in Argentina is a heterogeneous fungus, implying that screening wheat germoplasm for resistance for tan spot disease requires a wide range of pathogen isolates.
Identification of North American soybean lines that form nitrogen-fixing nodules with Rhizobium fredii USDA257
TLDR
The data indicate that the capacity to nodulate effectively with USDA257 is widespread in contemporary North American soybean lines, and the frequency of this response was positively correlated with increasing maturity group.
Differential regulation of laccase gene expression in Coriolopsis rigida LPSC No. 232.
TLDR
Results showed that upregulation due to copper was linked to growth stage, being highest during the trophophase and decreasing during the idiophase, and possible reasons for why laccase genes from C. rigida are differentially regulated at the transcriptional level are discussed.
Genetic diversity of Phaeoisariopsis griseola in Argentina as revealed by pathogenic and molecular markers
TLDR
The range of pathogenic responses might be conditioned by multigenic interactions between the pathogen and the host, and basic information about the diversity of the causative agent of the disease is provided.
Melanins in fungi: Types, localization and putative biological roles
TLDR
An enormous amount of work remains to be done to clarify the role melanins play in fungi, but it is clear that they play a different biological role than previously thought.
Transcriptional organization and expression of noIXWBTUV, a locus that regulates cultivar‐specific nodulatlon of soybean by Rhizobium fredii USDA257
TLDR
Analysis of transcriptional organization of a Sym plasmid locus that restricts the host range of R. fredii USDA257 and RNA dot blot data from a series of mutants indicates that noIBTUV is expressed as a single transcriptional unit in R.fredii.
