A Heat-Shock Transcription Factor in <i>Panax ginseng</i>, <i>PgHSFA2</i>, Confers Heat and Salt Resistance in Transgenic Tobacco.

ABSTRACT: Panax ginseng plants are susceptible to high temperatures and intense sunlight, necessitating cultivation under artificially shaded structures. Identifying the genes associated with heat resistance is critical for advancing molecular breeding strategies to develop heat-tolerant ginseng varieties. Heat-shock transcription factors (HSFs) are widely recognized as key regulators of plant responses to abiotic stresses, primarily by controlling heat-shock proteins (HSPs). To identify HSF genes in P. ginseng, transcriptome analysis was conducted on ginseng plants subjected to heat-shock treatment (1 h at 40 °C). Among the 26 HSF unigenes annotated from the ginseng transcriptome, a unigene related to the HSFA2 family exhibited the highest transcriptional activity following heat-shock
