Seed after-ripening and over-expression of class I ß-1,3-glucanase confer maternal effects on tobacco testa rupture and dormancy release

Gerhard Leubner-Metzger



Fig. 1  The effect of after-ripening and sense-ßGlu I transformation on testa (a-c) and endosperm (d-f) rupture of germinating tobacco seeds. Fresh (closed symbols) or after-ripened (open symbols) progeny seeds from reciprocal crosses of a homozygous monogenic sense-ßGlu I (TKSG7-32) or an empty-vector (TCIB1-2) line with wild-type (WT) were compared. The incidence of testa and endosperm rupture expressed as percentage was scored over time from the start of imbibition in continuous light in control medium. Mean values ± SE of four populations each with 100-150 seeds from independent capsules
