Long-distance signaling is an important process in the development of Arabidopsis thaliana. A leucine-rich repeat receptor-like kinase (LRR-RLK), XYLEM INTERMIXED WITH PHLOEM1 a.k.a. C-TERMINALLY ENCODED PEPTIDE RECEPTOR 1 (XIP1/CEPR1), functions in vascular development and has recently been implicated in nitrogen sensing and response. Previous results indicate that XIP1/CEPR1 also interacts with multiple proteins involved in sugar metabolism and transport as well as other metabolic proteins, which indicates a possible role for XIP1/CEPR1 in mediating sugar transport. xip1-1 seeds, which grow slowly in the cold in comparison to Columbia wild-type plants, were previously EMS mutagenized and screened for suppressors of the cold-sensitive phenotype. One of these suppressors, 9-12, maps to the lower region of chromosome V and several possible causative EMS-like mutations have been identified that may link XIP1/CEPR1 to a more general vascular transport role.
