The heat shock response (HSR) is an evolutionarily conserved molecular/biochemical reaction to thermal stress that is essential to the survival of eukaryotic organisms. Recessive Mutator transposon mutations at the maize empty pericarp2 (emp2) locus led to dramatically increased expression of heat shock genes, retarded embryo development, and early-stage(More)
The paralogous maize proteins EMPTY PERICARP2 (EMP2) and HEAT SHOCK FACTOR BINDING PROTEIN2 (HSBP2) each contain a single recognizable motif: the coiled-coil domain. EMP2 and HSBP2 accumulate differentially during maize development and heat stress. Previous analyses revealed that EMP2 is required for regulation of heat shock protein (hsp) gene expression(More)
The heat shock response (HSR) is a conserved mechanism by which transcripts of heat shock protein (hsp) genes accumulate following mobilization of heat shock transcription factors (HSFs) in response to thermal stress. Studies in animals identified the heat shock factor-binding protein1 (HSBP1) that interacts with heat shock transcription factor1 (HSF1)(More)
