To B or Not to B a Flower: The Role of DEFICIENS and GLOBOSA Orthologs in the Evolution of the Angiosperms

Article Abstract:

Examples of subfunctionalization and neofunctionalization are observed for DEFICIENS and GLOBOSA, even though their subfamily's primary role is to specify inner perianth and stamens. Discussion includes phylogeny, expression, and function in the DEF/GLO subfamily.

Segregation distortion for seed testa color in mungbean (Vigna radiata L. Wilcek)

Article Abstract:

In the study severe segregation distortion for testa color in mungbean populations derived from more closely related taxa is reported. This distortion could lead to erroneous conclusions about the inheritance of an easily scored trait such as testa color.

A Genetic Test of Bioactive Gibberellins as Regulators of Heterosis in Maize

Article Abstract:

Research on maize indicates that bioactive gibberellin modulation is a primary basis of plant heterotic response, using hybrid dwarf plants as an illustration.
