Thermotolerance Mechanisms in Heliotropium thermophilum: Integrating Biochemical Responses and Gene Expression Patterns

This transcriptomic study focuses on the molecular responses of plants subjected to heat stress, specifically examining the regulatory mechanisms and gene expression profiles associated with the accumulation of osmoprotectants like proline, soluble sugars, glycine-betaine, and phenolic compounds. The research investigates how these compounds contribute to cellular integrity, osmotic balance, and overall plant thermotolerance. Transcriptomic data were collected from Heliotropium thermophilum, sampled from two distinct soil temperature conditions, moderate (20-30 C) and high (55-65 C), at two different growth stages (pre-flowering and post-flowering). These data aim to delineate the adaptive genetic responses crucial for plant survival under varying thermal stresses. The insights gained from this study are pivotal for developing strategies to enhance crop resilience to heat stress, thereby addressing food security challenges posed by climate change.
