Lateral root initiation in Arabidopsis thaliana: a force awakens.

摘要: Osmotically driven turgor pressure of plant cells can be higher than that a car tire. It puts tremendous forces onto cell walls and drives growth changes in shape. This has given rise to unique mechanisms control organ formation compared metazoans. The fascinating interplay between local cellular reorganization is still poorly understood. Growth lateral roots prominent example developmental process which mechanical neighboring are generated must dealt with. Lateral initiate from single layer resides deep within the primary root. On their way out, grow through overlying endodermal, cortical, epidermal layers. was recently demonstrated endodermal actively accommodate root formation. Interfering genetically with these accommodating responses endodermis completely blocks proliferation pericycle. system provides opportunity elucidate molecular whereby intercellular communication regulate spatial accommodation during development.
