Heat shock protein genes involved in sensing and response to heat stress.
| Gene | Source | Trans-host/expression analysis | Function | References |
|---|---|---|---|---|
| TaHsfA6f | Cloned the TaHsfA6f gene from the heat and drought tolerant wheat cv. TAM107. | Arabidopsis | Through up-regulation of a number of genes involved in ABA metabolism and signaling, and other stress-associated genes. | Bi et al., 2020 |
| sHSP26 | Cloned the TaHsfA6f gene from bread wheat cv. CPAN1676 | Transgenic rice and Arabidopsis | Transgenic Arabidopsis plants were substantially tolerant under con tinuous high temperature regimen than wild-type plants, as measured by photosystem II (PSII) activity, accumulation of more photosynthetic pigments, higher biomass and seed yield. Transgenic plants produced bold seeds under high temperature, having higher germination potential than the wild-type plants. | Chauhan et al., 2012 |
| TaHsfA2d | Homology clone from rice gene rice OsHsfA2d | Arabidopsis | A heat shock factor (HSF) gene expressing preferentially in developing seed tissues of wheat grown under high temperatures, possess higher tolerance toward high temperature, also showed higher yield and biomass accumulation under constant heat stress conditions. | Chauhan et al., 2013 |
| TaHsfC2a-B | Using the sequences of Hsf DNA-binding domains from rice and Arabidopsis Hsf proteins for searching T. aestivum Hsf expressed sequence tags (ESTs) from the NBCI EST database | Transgenic wheat Fielder | A transcriptional activator of heat protection genes and serves as a proactive mechanism for heat protection in developing wheat grains via the ABA-mediated regulatory pathway. | Hu et al., 2018 |
| HSP90 | Clone from C-306 cultivar of wheat | Expression analysis of HSP90 gene in wheat C-306 | A high HSP90 transcript level along with high activities of antioxidant isoenzymes and low proline accumulation is a promising target for developing wheat genotypes with tolerance to heat stress. | Kumar et al., 2013 |
| HSP70 | Clone from a thermotolerant cultivar C306) of wheat | Expression analysis of HSP90 gene in wheat C-306 | The expression of HSP70 could decrease membrane stability and enhance total antioxidant capacity under heat stress. | Kumar et al., 2016 |
