Abstract Plants have evolved to anticipate and adjust their growth development in response environmental changes. To mitigate the negative influence of global climate change on crop production, understanding key regulators plant performance is imperative. EARLY FLOWERING 3 ( ELF3 ) such a regulator involved circadian clock thermomorphogenesis. Arabidopsis thaliana contains prion-like domain (PrLD) that functions as thermosensor, enabling its liquid-liquid phase separation at high ambient temperatures. understand conservation this function across kingdom, we traced evolutionary emergence with focus PrLD existence. We observed presence within ELF3, mainly contributed by length polyglutamine (polyQ) repeats, most prominent Brassicales . By analyzing 319 natural accessions, detected wide range polyQ variation ELF3. However, it only weakly associated geographic origin, conditions classic temperature-responsive phenotypes. Based available prediction tools limited experimental evidence, conclude although not likely be driver adaptation, adds an extra layer ELF3’s role

The escalating impact of global warming on crop yield and quality poses a significant threat to future food supplies. Breeding heat-resistant varieties holds promise, but necessitates deeper understanding the molecular mechanisms underlying plant heat tolerance. Recent studies have shed light initial events perception in plants. In this review, we provide comprehensive summary recent progress made unraveling response Calcium ion (Ca 2+ ), hydrogen peroxide (H 2 O nitric oxide (NO) emerged as key participants perception. Furthermore, discuss potential roles NAC transcription factor NTL3, thermo-tolerance 3.1 (TT3.1), Target temperature 3 (TOT3) thermosensors associated with plasma membrane. Additionally, explore involvement cytoplasmic HISTONE DEACETYLASE 9 (HDA9), mRNA encoding phytochrome-interacting 7 (PIF7), chloroplasts mediating This review also highlights role intranuclear transcriptional condensates formed by phytochrome B (phyB), EARLY FLOWERING (ELF3), guanylate-binding protein (GBP)-like GTPase (GBPL3) Finally, raise unresolved questions field that require further investigation future.
