We aimed to produce intergeneric hybrid plants with only one or a few alien chromosomes via microprotoplast fusion for genetic improvement and chromosome studies in Liliaceous ornamental plants. In order to apply this technique, it is essential to establish an efficient system for mass-preparation of microprotoplasts. We have established 2 different systems for isolating microprotoplasts, one f...

A tremendous diversity of avian color displays has stimulated numerous studies of natural and sexual selection. Yet, the developmental mechanisms that produce such diversification, and thus the proximate targets of selection pressures, are rarely addressed and poorly understood. In particular, because feathers are colored during growth, the dynamics of feather growth play a deterministic role i...
