The LEAFY COTYLEDON2 (LEC2) gene plays critically important regulatory roles during both early and late embryonic development. Here, we report the identification of the LEC2 gene from the castor bean plant (Ricinus communis), and characterize the effects of its overexpression on gene regulation and lipid metabolism in transgenic Arabidopsis plants. LEC2 exists as a single-copy gene in castor be...

The objectives of the present study were to monitor the effect of backcrossing through microsatellite markers and to compare different marker assisted selection strategies. Four populations were developed using donor parents resistant to the bean golden mosaic virus and, for all crosses, only individuals resistant to the bean golden mosaic virus were backcrossed. For crosses ARC100-4 x DOR303 a...

Gentiana species generally are of little importance to horticulture. This may explain that little attention has been given to virus infections in these ornamentals, so far. However, during the last couple of years the number of samples for virus diagnosis increased. The main symptoms recorded, were growth reduction, necrotic lesions and decline. The virus isolated most frequently was broad bean...

The most effective control of Bean common mosaic virus (BCMV) and necrosis (BCMNV) is achieved by using the seeds resistant cultivars. During conventional breeding, resistance against BCMV BCMNV in bean can be developed pyramiding strain-nonspecific dominant I gene with strain-specific recessive (bc-) genes for long-term control. In this study, a total 58 genotypes involving registered green dr...

Extracellular agents produced by newly isolated bacterial strains were able to catalyze the synthesis of silver nanoparticles (AgNPs). The most effective isolates were identified as Bacillus pumilus, B. persicus, and Bacillus licheniformis using molecular identification. DLS analysis revealed that the AgNPs synthesized by the above strains were in the size range of 77-92 nm. TEM observations sh...

Hobbs, H. A., and Kuhn, C. W. 1987. Differential field infection of cowpea genotypes by southern bean mosaic virus. Phytopathology 77:136-139. Natural spread of the cowpea strain of southern bean mosaic virus among susceptible lines and between susceptible and resistant lines. (SBMV) from infected cowpea to several cowpea genotypes, including Inoculation by needle pricking showed similar levels...
