Two Populations of Viral Minichromosomes Are Present in a Geminivirus-Infected Plant Showing Symptom Remission (Recovery).

Unlabelled: Geminiviruses are important plant pathogens characterized by circular, single-stranded DNA (ssDNA) genomes. However, in the nuclei of infected cells, viral double-stranded DNA (dsDNA) associates with host histones to form a minichromosome. In phloem-limited geminiviruses, the characterization of viral minichromosomes is hindered by the low concentration of recovered complexes due to the small number of infected cells.

Genome-wide analysis of the beta-glucosidase gene family in maize (Zea mays L. var B73).

The hydrolysis of beta-D: -glucosidic bonds which is required for the liberation of many physiologically important compounds is catalyzed by the enzyme beta-glucosidase (BGLU, EC 3.2.1.
