About this Research Topic
Recent studies exploiting different experimental systems to investigate transfer cell biology have identified signaling pathways inducing transfer cell development and genes/gene networks that define transfer cell identity and/or are involved in building the wall ingrowth labyrinths themselves. Further studies have defined the structure and composition of wall ingrowths in different systems, leading in many instances to the conclusion that this process may involve previously uncharacterized mechanisms for localized wall deposition in plants. Since transfer cells play important roles in plant development and productivity, the latter being relevant to crop yield, especially so in major agricultural species such as wheat, barley, soybean and maize, understanding the molecular and cellular events leading to wall ingrowth deposition holds exciting promise to develop new strategies to improve plant performance, a key imperative in addressing global food security.
This Research Topic is seeking contributions covering all aspects of the biology of transfer cells and syncytia/giant cells. We believe it is timely to generate a comprehensive treatise on transfer cell biology to help define critical questions for future research and thereby generating a deeper understanding of these fascinating and important cells in plant biology. Contributions are welcomed in the form of opinion papers, reviews, or research papers, and will be selected based on peer-review according to the procedures used by Frontiers in Plant Science.
Research fields identified for coverage:
Experimental systems to study transfer cells
Morphology of wall ingrowths and their composition
