摘要： FK506 binding proteins, a member of peptidyl-prolyl cis-trans isomerase (PPIase), are essential for plant growth; however, the molecular function of FKBPs remains largely unknown. In this report, we isolated and identified an FK506 binding protein, OsFKBP42b, that regulates rice growth and development. The OsFKBP42b mutation led to reductions in plant height, panicle length, and seed setting rate. Scanning electron microscopy of the wild-type and the mutant stems showed no difference in cell size. OsFKBP42b was expressed in rice various organs, especially in panicles, leaves, and stems. Subcellular localization suggested that OsFKBP42b was a plasma membrane protein. Furthermore, we found that OsFKBP42b interacted with the ATP binding cassette B proteins, OsABCB1 and OsABCB14, by yeast two-hybrid and bimolecular fluorescence complementation assays. Taken together, our results provide new insights into OsFKBP42b in rice.
