The expression of histone 2A in onion (Allium cepa) during the onset of dormancy, storage and emergence from dormancy.

The tissue-specific and developmental expression of histone 2A was studied in onion (Allium cepa'Robusta'), using northern blots. Histone 2A expression was enriched in basal tissues, particularly in the inner, meristematically active parts of bulbs. The expression was assessed during a time course of bulb development, dormancy onset and post-harvest sprouting in field-grown material.
