The Arabidopsis HOS1 gene negatively regulates cold signal transduction and encodes a RING finger protein that displays cold-regulated nucleo-cytoplasmic partitioning
Article Abstract:
The Arabidopsis thaliana HOS1 gene has been found to negatively regulate cold signal transduction. It also encodes a RING finger protein that displays cold-regulated nucleo-cytoplasmic partitioning. Low temperature is a very important environmental stimulus in controlling gene transcription programs and development in plants. Map-based cloning and molecular analysis of HOS1, the first genetic locus involved in cold-regulated plant development and signaling to be characterized at the molecular level, has been undertaken to find the molecular nature of the key regulatory genes involved.

BIG: a calossin-like protein required for polar auxin transport in Arabidopsis
Article Abstract:
Research has shown that doc1 mutants are allelic to tir3 mutants and that they define BIG, a calossin-like protein necessary for Arabidopsis polar auxin transport. The BIG gene, which is very large, giving a reason for the name, likely encodes an enormous protein with significant identity to the Drosophila protein Calossin/Pushover.
