摘要：
The present invention relates to a method for modifying plant growth and development processes by affecting cell cycle regulation comprising modulating expression of members of the plant E2F transcription factor family. More specific the invention relates to methods for stimulating cell division in a plant. The invention further relates to transgenic plants produced by the methods of the invention having altered plant growth and development characteristics compared to their isogenic counterparts. Preferably, the plant characteristics modified by the present invention include enlarged cotyledons, enhanced growth rate, stress resistance and seedling survival, more cells, more tillers, more panicles.
