The "Havana 425" cultivar of Nicotiana tabacum L. is photodormant. Gibberellins (e.g. 10 .5 M GA4 or GA7) can substitute for light in releasing dormancy. Measurements of [3-1,3-glucanase activity, mRNA accumulation and the activity of the class I [3-1,3-glucanase B promoter indicated that class I [3
