Popis: | Plants have a remarkable regenerative capacity, but it varies widely among species and tissue types. Whether plant cells/tissues initiate regeneration largely depends on the extent to which they are constrained to their original tissue fate. Once cells start the regeneration program, they acquire a new fate, form meristems, and develop into organs. During these processes, the cells must continuously overcome various barriers to the progression of the regeneration program until the organ (or whole plant) is complete. Recent studies have revealed key factors and signals affecting cell fate during plant regeneration. Here, we review recent research on: (i) environmental signal inputs and physical stimuli that act as initial triggers of regeneration; (ii) epigenetic and transcriptional cellular responses to those triggers leading to cellular reprograming; and (iii) molecules that direct the formation and development of the new stem cell niche. We also discuss differences and similarities between regeneration and normal development. |
