Section: H 2 S Response To Ht Stressmentioning

“…HT leads to multiple injuries at the molecular, physiological, biochemical, subcellular, cellular, and whole plant body levels ( Wani and Kumar, 2020 ; Zhang et al., 2022 ; Huang et al., 2023 ; Kan et al., 2023 ). HT injury is implicated in biomembrane damage, protein denaturation, Ca 2+ overload toxicity, ion and acid imbalance, and oxidative, osmotic, and MG stress ( Kosová et al., 2021 ; Zhao et al., 2021 ; Zhang et al., 2022 ; Zhou et al., 2022a ,; Huang et al., 2023 ; Kan et al., 2023 ; Wang et al., 2023c ) ( Figure 3 ). Therefore, plant HT tolerance is closely related to the repair of biomembrane (RBM), stress protein biosynthesis (SPB), Ca 2+ ion equilibrium (CIE), ROS homeostasis (ROH), osmoregulation (OSR), MG balance (MGB), ion equilibrium (IEB), and pH value stability (PVS) in plants ( Zhang et al., 2022 ; Zhou et al., 2022a , Zhou et al., 2022b ; Huang et al., 2023 ; Kan et al., 2023 ; Wang et al., 2023c ) ( Figure 4 ; Table 1 ).…”

For the past 300 years, hydrogen sulfide (H2S) has been considered a toxic gas. Nowadays, it has been found to be a novel signaling molecule in plants involved in the regulation of cellular metabolism, seed germination, plant growth, development, and response to environmental stresses, including high temperature (HT) and low temperature (LT). As a signaling molecule, H2S can be actively synthesized and degraded in the cytosol, chloroplasts, and mitochondria of plant cells by enzymatic and non-enzymatic pathways to maintain homeostasis. To date, plant receptors for H2S have not been found. It usually exerts physiological functions through the persulfidation of target proteins. In the past 10 years, H2S signaling in plants has gained much attention. Therefore, in this review, based on that same attention, H2S homeostasis, protein persulfidation, and the signaling role of H2S in plant response to HT and LT stress were summarized. Also, the common mechanisms of H2S-induced HT and LT tolerance in plants were updated. These mechanisms involve restoration of biomembrane integrity, synthesis of stress proteins, enhancement of the antioxidant system and methylglyoxal (MG) detoxification system, improvement of the water homeostasis system, and reestablishment of Ca2+ homeostasis and acid-base balance. These updates lay the foundation for further understanding the physiological functions of H2S and acquiring temperature-stress-resistant crops to develop sustainable food and agriculture.

Brassinosteroids (BR) are essential plant hormones that play a crucial role in regulating plant growth and development, as well as their resistance to abiotic and biotic stresses, including pathogen infections. In the context of plant im-munity, BR influence various processes such as the expression of genes related to pathogen defense, the production of antimicrobial compounds, and the re-inforcement of the plant cell structure. The aim of work is understand the role of BR in plant defense against abiotic and biotic stresses. BR are involved in the regulation of metabolic processes, water economy, and photosynthesis, contributing to increased plant resistance to abiotic stresses. The study discusses various mechanisms of BR action on plant immunity, including the regulation of gene expression related to defense, activation of the plant defense system, in-teraction with other plant hormones, regulation of water and salt balance, and influence on photosynthetic processes. In the context of plant immunity, BR influence various processes, including the expression of genes related to pathogen defense, the production of antimicrobial compounds, and the reinforcement of the plant cell structure. Additionally, BR are involved in the regulation of metabolic processes, water economy, and photosynthesis, con-tributing to increased plant resistance to abiotic and biotic stresses. The paper emphasizes the importance of further research on the role and mechanisms of action of BR in plant immunity, which may contribute to the development of more effective strategies for the use of BR in agriculture, horticulture, and plant protection.

“…Changes in plant gene transcription levels not only directly re ect the species' adaptive potential to current environments but are also essential for assessing the viability of natural species under climate change and for developing effective ecological and forest management strategies. During the process of adapting to environmental stress, plants undergo extensive changes in gene expression (Z.-H. Chen and Soltis 2020; Kan et al 2023), providing a basis for natural selection on short evolutionary timescales (Xu et al 2016; Innes et al 2023).…”

In the context of climate change, assessing the adaptive potential of species and populations is crucial for developing effective conservation strategies. Changes in plant gene expression play a significant role in the adaptation process to climate change. This study aims to explore the adaptive responses of the near-threatened conifer species Chamaecyparis hodginsii to climate change and analyze the molecular-level reactions of these long-lived trees to climatic shifts. It seeks to understand their phenotypic responses to climate change, identify key environmental factors driving adaptive gene expression, and provide information for transplantation conservation strategies based on genetic adaptability. By conducting mixed-tissue RNA sequencing on seeds from multiple provenances and employing redundancy analysis (RDA), weighted gene co-expression network analysis (WGCNA), and partial least squares path modeling (PLS-PM), the study assesses the impact of climatic variables on gene expression and phenotype. It identifies key gene groups associated with environmental responses and elucidates the complex relationships between environmental factors, functional gene groups, and phenotypic traits. The findings reveal that C. hodginsiiadapts to environmental stresses by regulating specific gene activities related to morphological trait adjustments. Moreover, environmental factors such as the impact on tree architecture emphasize the importance of Precipitation Seasonality, Isothermality, and Precipitation of Driest Quarter for adapting to climate stresses. This research not only unveils the complex adaptive responses of C. hodginsii to climate change but also provides critical insights for the management and conservation of long-lived tree species facing climate change threats.
