“…The ERF transcription factor LATE FLOWERING SEMI-DWARF ( LSF ) in rice ( Oryza sativa ) responds to long photoperiods and induces flowering by removing the suppressive effect [ 21 ]. LlERF110 in lily is rapidly induced by high temperature, and its overexpression reduces plant heat tolerance while simultaneously suppressing key flowering genes AtFUL , AtAP1 , AtLFY , and AtSOC1 , resulting in delayed bolting in Arabidopsis [ 22 , 29 ]. CmERF110 in Chrysanthemum morifolium responds to photoperiodic signals and interacts with the key factor FLK in the autonomous pathway to regulate chrysanthemum flowering.…”

Background Larch is an important component of northern forests and a major cultivated tree species in restoration of forest cover using improved seed material. In recent years, the continuous low seed production has severely affected the production of improved variety seedlings and natural regeneration. However, research on the reproductive growth of gymnosperms is extremely scarce. Results In this study, based on differential transcriptome analysis of two asexual reproductive phases, namely high-yield and low-yield, we further screened 5 ERF family genes that may affect the reproductive development of larch. We analyzed their genetic relationships and predicted their physicochemical properties. The expression patterns of these genes were analyzed in different tissues, developmental stages, hormone treatments, and environmental conditions in hybrid larch. Conclusion The results showed that all 5 genes were induced by low temperature and ABA, and their expression patterns in different tissues suggested a suppressive role in the development of female cones in larch. Among them, LkoERF3-like1 and LkoERF071 may be involved in the flowering age pathway. This study enriches the scarce research on reproductive development in gymnosperms and provides a theoretical basis and research direction for regulating the reproductive development of larch in seed orchards.

“…AtWRKY25, AtWRKY26, and AtWRKY33 positively regulate the cooperation between the ET-activated and HSPs-related signaling pathways that mediate responses to HS ( Li et al., 2011 ). HSFA1, HSFA2a, HSFA2b, HSFA3a, HSFA3b, HSFA4, DREB2B, MYB305, WRKY22, WRKY39, MBF1c, NAC014, HB16, and ERF110 have been identified from ornamental lily, and all of these TFs are positively correlated with lily thermotolerance ( Xin et al., 2010 ; Gong et al., 2014 ; Wu et al., 2018a ; Wu et al., 2018b ; Wu et al., 2019 ; Ding et al., 2021 ; Wang C, et al, 2022 ; Wang Y, et al, 2022 ; Wu et al., 2021 ; Wu et al., 2022a ; Wu et al., 2022b ; Xin et al., 2017 ; Zhou Y, et al, 2022 ; Wu et al., 2023 ).

Lanzhou lily (Lilium davidii var. unicolor) is a renowned edible crop produced in China and relatively sensitive to high temperature (HT). Trichokonins (TKs) are antimicrobial peptaibols secreted from Trichoderma longibrachiatum strain SMF2. Here, we report that TKs application improves the thermotolerance of Lanzhou lily. The activity of the antioxidant enzyme system (SOD, CAT, and POD), the level of heat-resistance-associated phytohormones (ABA, SA, and JA), the relative water content (RWC), the content of chlorophyll (Chl), and the net photosynthetic rate (Pn) were promoted by TKs treatment in Lanzhou lily plants subjected to heat stress (HS). TKs treatment also mitigated cell injury as shown by a lower accumulation of malondialdehyde (MDA) and relative electrolyte leakage (REL) under HS conditions. RNA-seq data analysis showed that more than 4.5 times differentially expressed genes (DEGs) responded to TKs treatment under HS compared to non-HS, and TKs treatment reduced protein folding and enhanced cellular repair function under HS conditions. The analyses of DEGs involved in hormone (ABA, SA and JA) synthesis and signaling pathways suggested that TKs might improve Lanzhou lily heat tolerance by promoting ABA synthesis and signal transduction. TKs highly induced DEGs of the HSF-HSP pathway under HS, in which HSFA2 accounted for most of the HSF family. Furthermore, TKs treatment resulted in the upregulation of heat-protective genes LzDREB2B, LzHsfA2a, LzMBF1c, LzHsp90, and LzHsp70 involved in HSF-HSP signal pathway after long-term HS. LzHsfA2a-1 likely plays a key role in acquisition of TKs-induced thermotolerance of Lanzhou lily as evidenced by the sustained response to HS, the enhanced response to TKs treatment under long-term HS, and the high sequence similarity to LlHsfA2a which is a key regulator for the improvement of heat tolerance in Lilium longiflorum. Our results reveal the underlying mechanisms of TKs-mediated thermotolerance in Lanzhou lily and highlight an attractive approach to protecting crop plants from damage caused by HS in a global warming future.

“…Virus-induced gene silencing of LlERF110 in lilies resulted in reduced expression of LlHsfA2, LlHsfA3A, and LlHsfA5 (involved in the heat shock factor (HSF)–heat shock proteins (HSP) signaling pathway), as well as LlHsp17.6 and LlHsp22 whichseem to protect proteins under heat stress. Ethylene signaling via LlERF110 appears to play a crucial role in lily basal thermotolerance through regulation of the HSF–HSP signaling pathway [ 95 ] Basal thermotolerance targets the plant’s ability to resist heat stress, while acquired thermotolerance or thermopriming is a phenomenon based on improved heat tolerance due to previous exposure to sublethal heat stress [ 96 ], of which the following study provides an example. In Arabidopsis, ethylene signaling has been proposed to induce heat tolerance by transcriptionally activating ERF95 and ERF97 through EIN3, both of which then activate Heat Shock Factor A2 (HSFA2).…”

Plants are sessile organisms that face environmental threats throughout their life cycle, but increasing global warming poses an even more existential threat. Despite these unfavorable circumstances, plants try to adapt by developing a variety of strategies coordinated by plant hormones, resulting in a stress-specific phenotype. In this context, ethylene and jasmonates (JAs) present a fascinating case of synergism and antagonism. Here, Ethylene Insensitive 3/Ethylene Insensitive-Like Protein1 (EIN3/EIL1) and Jasmonate-Zim Domain (JAZs)-MYC2 of the ethylene and JAs signaling pathways, respectively, appear to act as nodes connecting multiple networks to regulate stress responses, including secondary metabolites. Secondary metabolites are multifunctional organic compounds that play crucial roles in stress acclimation of plants. Plants that exhibit high plasticity in their secondary metabolism, which allows them to generate near-infinite chemical diversity through structural and chemical modifications, are likely to have a selective and adaptive advantage, especially in the face of climate change challenges. In contrast, domestication of crop plants has resulted in change or even loss in diversity of phytochemicals, making them significantly more vulnerable to environmental stresses over time. For this reason, there is a need to advance our understanding of the underlying mechanisms by which plant hormones and secondary metabolites respond to abiotic stress. This knowledge may help to improve the adaptability and resilience of plants to changing climatic conditions without compromising yield and productivity. Our aim in this review was to provide a detailed overview of abiotic stress responses mediated by ethylene and JAs and their impact on secondary metabolites.
