The Dormancy Marker DRM1ARP Associated with Dormancy but a Broader Role In Planta

الملخص EN

Plants must carefully regulate their development in order to survive a wide range of conditions.

Of particular importance to this is dormancy release, deciding when to grow and when not to, given these varying conditions.

In order to better understand the growth release mechanism of dormant tissue at the molecular and physiological levels, molecular markers can be used.

One gene family that has a long association with dormancy, which is routinely used as a marker for dormancy release, is DRM1/ARP (dormancy-associated gene-1/auxin-repressed protein).

This plant-specific gene family has high sequence identity at the protein level throughout several plant species, but its function in planta remains undetermined.

This review brings together and critically analyzes findings on the DRM1/ARP family from a number of species.

We focus on the relevance of this gene as a molecular marker for dormancy, raising questions of what its role might actually be in the plant.
