Summary: Plants face various environmental cues that lead to significant losses in crop productivity. The defense mechanisms developed by plants against herbivores and pathogens can be either preformed or inducible, helping them generate appropriate responses to attacks. The interplay between different signals in generating defense responses against biotic stress, especially the impact of light and dark signals, remains elusive.

Summary: This review highlights the novel roles of calcium signaling in coordinating plant stem cell niche homeostasis for root and shoot development, as well as its regulatory networks with other plant signaling pathways. It also discusses the possible functions of calcium in plant growth responses, the plant circadian system, and abiotic/biotic stress responses.

Summary: Phytochromes, as receptors for red and far-red light, not only regulate plant growth and development but also mediate resistance to various stresses. Recent studies have shown that phytochrome signaling pathways play a crucial role in enabling plants to cope with abiotic and biotic stresses. This paper reviews the mechanisms of action of phytochromes in plant resistance to adversity and discusses the importance of modulating genes involved in phytochrome signaling pathways for coordinating plant growth, development, and stress responses.

Summary: As sessile organisms, plants face constant challenges from a changing environment, including fluctuations in temperature, water availability, light levels, and changes in atmospheric constituents such as CO2 and O3. They also experience biotic stress from plant pathogens and herbivores. Increased atmospheric CO2 levels and climate change are impacting plant growth environments and the prevalence and virulence of plant pathogens. Closing the knowledge gap in plant responses to biotic and abiotic stress is crucial for developing climate resilient crops in the future.

Summary: Plants play a crucial role in ecological interactions and their transgenerational memory is essential for their ability to combat biotic stress. Recent studies have shown that plants can transfer stress signaling events as genomic imprints across successive generations, enhancing their immune response against biotic stresses.

Summary: The metabolism of green algae, particularly the interrelation between NADPH and H-2 accumulation, plays a crucial role in maintaining redox balance under light fluctuations. Energy transfer between H-2 and NADPH is found to be bidirectional and essential for initiating photosynthetic electron flow, as well as dark fermentative metabolism.

Summary: Putrescine is the starting point of the polyamines pathway and plays a crucial role in plant growth and development, as well as tolerance responses to stresses. Various research methods, including competitive inhibitors, exogenous Putrescine treatment, and mutant and transgenic plants, have been used to investigate its involvement in plant systems.

Summary: Plant epigenetics has great potential for improving plant adaptation to stress factors, but a thorough understanding and assessment of the functional relevance of epigenetic modifications are required. Modern technologies for profiling and engineering plants at the genome-wide scale have provided new insights into the mechanisms of epigenetic modifications in response to stress conditions and their contribution to plant phenotypes. Understanding the patterns of epigenetic variations can help develop breeding strategies for improving crop performance under stressed scenarios.

Summary: Human activity is causing a global change in plant environment, resulting in a significant decrease in plant growth and survival. This is due to the increase in the number and complexity of stressors, both biotic and abiotic, that simultaneously or sequentially impact plants. Even if each individual stressor does not have a significant effect, the cumulative effect of multiple stressors leads to a dramatic decline in plant growth and survival.

Summary: This review discusses the crucial role of nitric oxide (NO) in plant life cycle and its involvement in physiological and biochemical processes and gene expression. It also explores the interaction network of NO with other molecules in plant cells and highlights the defense response mechanisms against infestation with Ecdysozoa species. Further research on the involvement of NO in host plants and Ecdysozoa parasites interactions, especially arachnids, is emphasized.

Summary: Adverse variations of abiotic environmental cues can cause stress to plants, leading to reduced crop yield and negative impact on ecosystem stability. Ca2+ plays multifaceted roles in abiotic stress responses, serving as a versatile second messenger and connecting stress perception to signal transduction.
