Although plant growth is affected by environmental factors, the final size and shape of organs are species-specific. Understanding the mechanisms controlling organ size and shape in different plant species could shed light on the nature of plant diversity. Meanwhile, organ size and shape directly associate with crop yield and quality. Identification of key regulators of organ size and shape would provide new genetic targets for crop improvement.

 

The final organ size and shape are determined by coordination of cell proliferation, expansion and differentiation during organ development, which is strictly controlled by the genetic and developmental signals. Although recent studies have identified some signals and pathways that regulate plant organ size and shape, challenges remain for understanding the genetic and molecular network controlling organ size and shape in plants. This research topic will focus on new advances in the genetic and molecular mechanisms that control final organ size and shape in plants.

 

We welcome submissions of different types of manuscripts including original research papers, reviews, and methods, including but not limited to:

 

1. Genetic and molecular mechanisms regulating the size or shape of leaves, flowers, and fruits or seeds

2. Identification and characterization of novel genetic and epigenetic regulators for organ size or shape

3. Conserved mechanisms of organ size and shape control in different plant species

4. Diverse mechanisms of organ size and shape control in different plant species

Keywords: plant, organ size, organ shape, leaf, floral organ, seed, fruit


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
