Altered morphology of buds, flowers, floral organs and siliques of pPLAIIIδ -overexpressing Brassica napus plants. (A) Morphology of buds, flowers, floral organs, and siliques. Overexpressing pPLAIIIδ in B. napus leads to morphologic alterations in floral organs and siliques similar to those in Arabidopsis. Bar = 1 cm. (B) Measurement of buds and various floral organs. Buds and all floral organs in independent lines overexpressing pPLAIIIδ (BnOE1 to BnOE4) decrease in length, whereas the width of the petal is increased. All values are means ± SE based on 15 samples. * and ** indicate significant differences at P ≤0.05 and at P ≤0.01, respectively, by Student’s t test.
