Autophagy modulates growth and development in the moss Physcomitrium patens

Physcomitrium patens apical growing protonemal cells have the singularity that they continue to undergo cell divisions as the plant develops. This feature provides a valuable tool to study autophagy in the context of a multicellular apical growing tissue coupled to development. Herein, we showed that the core autophagy machinery is present in the moss P. patens, and characterized the 2D and 3D growth and development of atg5 and atg7 loss-of-function mutants under optimal and nutrient-deprived conditions.

Abstract:
Physcomitrium patens apical growing protonemal cells have the singularity that they continue to undergo cell divisions as the plant develops.
