The unfolded protein response (UPR) or the endoplasmic reticulum (ER) stress response occurs when folding and maturation of secretory and membrane proteins are impaired in the ER. The UPR induces a number of genes that encode ER-localized molecular chaperones and folding enzymes to increase folding capacity in the ER. We have identified Tunicamycin Induced 1 ( TIN1 ), an Arabidopsis gene that is highly induced during the UPR. We have shown that TIN1 protein is localized in the ER but its physiological function remains to be elucidated. In the present study we generated and analyzed transgenic Arabidopsis plants expressing TIN1 under CaMV35S promoter to obtain insights into the physiological role of TIN1. We found that although TIN1 -overexpressing plants grew as did wild-type plants under ambient laboratory conditions, their pollen grains exhibited abnormal surface morphology. The result suggests a specific role of TIN1 in secretion of proteins and/or lipids during pollen development.
