| Unfolded protein response (UPR) is a signaling mechanism activated by misfolded protein accumulation in the endoplasmic reticulum. It is a widespread process that has been described in organisms ranging from yeasts to mammals. In recent years, our understanding of UPR signaling pathway in plants has advanced. Two transcription factors from Arabidopsis thaliana have been reported to function as the sensor/ transducer of this response (AtbZIP60 and AtbZIP28). They seem to be involved in both heat and biotic stress. Furthermore, overexpression of one of them (AtbZIP60) produces plants with a higher tolerance for salt stress, suggesting that this transcription factor may play a role in abiotic stress. Furthermore, some data suggest that crosstalk between genes... |

| In contrast to yeast or mammalian counterpart, BiP (Binding Protein) from several plant species, such as maize, tobacco, Arabidopsis and soybean, is encoded by a multigene family. A systematic characterization and analysis of soybean BiP expression have provided evidence for the existence of multiple, complex regulatory mechanisms controlling plant BiP gene expression. In support of this observation, the soybean BiP gene family has been shown to exhibit organ-specific expression and differential regulation in response to abiotic stresses through distinct signaling pathways. As a member of the stress-regulated HSP70 family of protein, the elucidation of plant BiP function and regulation is likely to lead do new strategies to enhance crop tolerance to... |
