ARL — Asparagus officinalis

Summary

A4U43_UNF2390 (AoARL, ARL) encodes an ARGOS-like protein, a member of the ARGOS/ARL/OSR1 family. In asparagus, this gene is associated with the cell cycle, particularly M phase and cell cycle phase, as well as positive regulation of organ growth, multidimensional cell growth, and upregulation of cell proliferation. It is associated with responses to hormones including auxin, ethylene, and brassinosteroids, and with brassinosteroid-mediated signalling. The protein is localised to the cytoplasm, nucleus, membrane, ER, and mitochondria. Studies of related genes in other species link the family to organ size traits such as leaf size, flower diameter, seed size, and stem size, as well as to stress responses including salt tolerance and drought tolerance, and to heterosis.
