additional information | AGP-antisense plants show flowers with abnormal petal limbs due to the early termination of the expansion growth of the petal limbs between the corolla lobes, the cell expansion is limited in NtAGP-antisense plants but cell numbers remained unchanged. Enzyme mRNA levels and starch content in the sepal tissues of AGP-antisense plants are reduced, resulting in significantly lower levels of sugars, sucrose, glucose, and fructose, in the petal limbs. The feeding of these sugars to flower buds of the AGP-antisense plants restores the expansion growth in the limb area between the corolla lobes, which is severely arrested in ยXanthiย flowers from which sepals are removed | Nicotiana tabacum |
