Summary: Understanding the regulation of fleshy fruit ripening is important for controlling ripening time and improving fruit quality. MADS-box transcription factors (TFs) play a key role in the genetic networks controlling fruit ripening. This review highlights the involvement of MADS-box TFs in ethylene-dependent and independent pathways, carotenoid biosynthesis, cell wall metabolism, gibberellin synthesis, and abscission pathways in controlling fleshy fruit ripening. The review also discusses the diversity of components in the control network and their interactions in ripening progression.

Summary: Abscisic acid (ABA) is a plant growth regulator that plays crucial roles in seed maturation, dormancy, stress responses, and leaf and bud abscission. ABA activity is controlled by multiple regulatory pathways, including biosynthesis, signal transduction, and transport. ABA transports from the shoot to the fruit, where it interacts with ethylene during fruit ripening. The understanding of the mechanisms governing ABA's role in fruit growth and ripening is still unfolding.

Summary: Fruit ripening is a highly regulated developmental process aiming to attract herbivores by maximizing organoleptic traits. The process involves coordinated changes in color, flavor, and firmness. Dynamic interactions between hormones, transcription factors, and epigenetic modifications establish a complex regulatory network for ripening-related gene expression.

Summary: Exogenous treatment with BR suppresses ethylene production and delays fruit ripening, while inhibition of BR biosynthesis promotes ethylene production and accelerates fruit ripening in pear. The transcription factor PuBZR1 interacts with PuACO1 to suppress its activity, thereby reducing ethylene production and inhibiting fruit ripening. This mechanism may be conserved in other climacteric fruits like apple.

Summary: High-altitude climates have unique characteristics that affect the physical structure and physiological functions of plants. Studying plant adaptation to high altitudes is crucial for understanding how they respond to abiotic stress. The adverse environment of mountainous areas provides an ideal natural laboratory for examining speciation and adaptive evolution. Recent research suggests that climate change may impact plant adaptation and disrupt local adaptation. Genome/transcriptome sequencing and other techniques have revealed the genes and molecular mechanisms involved in energy consumption and stress response in high-altitude plants. Secondary metabolites from medicinal plants, such as alkaloids and polyphenols, are widely used in traditional medicine and drug development, and are analyzed using omics technologies. Morphological statistics and multi-omics approaches have been used to explore plant adaptation to high-altitude settings and have advanced our understanding of the underlying biology. This review provides valuable insights for researchers in the fields of medicinal plant biotechnology, chemical genetics, and adaptation biology.

Summary: In this study, the function of the GNEV727M mutation was investigated. The mutation caused deregulated expression of lincRNAs, and the associated target genes were found to play important roles in regulating Wnt, TGF-beta, and apoptotic signaling. Additionally, a 13 gene signature specific to the COL6A3 gene was found to be altered in multiple muscular disorders. Therefore, investigating the changes in the COL6A3 gene provides valuable information for understanding the molecular cause of HIBM and may lead to improved diagnosis and treatment strategies for various muscular disorders.

Summary: Cadmium (Cd) and Mercury (Hg) are hazardous heavy metals to plant and human health. They induce oxidative stress and disrupt the antioxidant defence system, leading to damage at cellular and molecular levels. This study investigated the deleterious effects of Cd and Hg on soybean plants and the response of antioxidant enzymes and RNA. Both Cd and Hg increased oxidative stress and upregulated antioxidant enzymes. The quality and stability of RNA were affected, but the Actin gene was upregulated in the presence of Cd to limit the damage caused by the metals.

Summary: Tropospheric ozone has significant effects on the remobilization and allocation efficiency of aboveground biomass and nutrients in cereal crops. Long-term ozone exposure increases straw C:N ratio and affects grain C:N ratio. Grain N concentrations increase significantly under ozone stress, but N yield declines due to grain yield losses. Various indicators of N use efficiency are reduced, indicating reduced N absorption from soil and allocation from vegetative to reproductive organs. Straw C:N ratio is not suitable for predicting wheat productivity. Nitrogen harvest index (NHI) is not affected by ozone stress, but the relationship between harvest index (HI) and NHI is changed by elevated ozone concentration.

Summary: This study aimed to investigate the physiological response of broccoli leaves to abiotic stresses such as salinity and boron toxicity/deficiency. The results showed that the combined stress of salinity and boron deficiency resulted in a significant reduction in plant biomass, and the adaptation mechanisms were associated with water and boron concentration in the leaves. The expression patterns of PIP aquaporins varied among the different stress treatments, and their presence in the plasma membrane and interaction with the lipid environment played potential regulatory roles in facilitating salinity-boron stress adaptation mechanisms.

Summary: Plants activate a sophisticated signaling cascade in response to pests and pathogens, with lipids playing a crucial role in mediating these defense responses. Different types of lipids are involved in cell signaling during plant-pathogen interaction and each lipid has specific relevance and contributes to specific signaling cascades. Lipid biosynthetic enzymes, including phospholipases, are involved in the production of defense signaling molecules. Lipids participate in stress signaling by mediating signal transduction, acting as precursors for bioactive molecules, regulating ROS formation, and interacting with phytohormones.
