In the era of global climate change, five cardinal oilseed mustards such as Brassica juncea, Brassica nigra, Brassica rapa, Brassica carinata, and Brassica napusare at alarming risk. Indeed, heat stress adversely affects their survival potential, growth rate, metabolism, yield, productivity, and oil content. To withstand extreme temperature by supplementing more top-notched genetically engineered thermostable mustard crops, we need to understand the differential expression patterns of heat shock proteins (HSPs), transcription factors (e.g. HSFs, NAC, DREB) and growth regulators as well as the transcriptional modulator network between HSPs and other chaperone proteins (e.g. calnexin, protein kinases). Furthermore, some HSPs initiate the degradation of misfolded and denatured proteins while others interact and bind to numerous types of folding intermediates and inhibit misfolded proteins from aggregating and promote refolding and activation of non-native and other chaperone proteins that have initially aggregated. A condensed version of the information on the interactions between HSPs is presented in this review and other chaperone like proteins along with the comprehensive knowledge of their scavenging interaction and modulation under elevated temperature conditions in oilseed mustard crop varieties to develop thermo-resilient mustard crops.
