Constitutive E2F expression in tobacco plants exhibits altered cell cycle control and morphological change in a cell type-specific manner

From: Plant Physiology | Date: August 1, 2003| Author: | Copyright information

The E2F family plays a pivotal role in cell cycle control and is conserved among plants and animals, but not in fungi. This provides for the possibility that the E2F family was integrated during the development of higher organisms, but little is known about this. We examined the effect of E2F ectopically expressed in transgenic tobacco (Nicotiana tabacum) plants on growth and development using E2Fa (AtE2F3) and DPa from Arabidopsis. E2Fa-DPa double transgenic lines exhibited altered phervotypes with curled leaves, round shaped petals, and shortened pistils. In mature but not immature leaves ...
