Summary: The C-2 carbon-concentrating mechanism increases CO2 assimilation by shuttling photorespiratory CO2 from mesophyll to bundle sheath cells. NH3 influx caused by this mechanism may lead to nitrogen imbalance and select for C-4 mechanism. Our alternative hypothesis explains the vital roles of bundle sheath NH3 and serine in C-2 plants and their stress tolerance. Optimized bundle sheath nitrogen hub interacts with sulfur and carbon metabolism to mitigate the effects of high photorespiratory conditions.

Summary: Photolytic generation of nitric oxide (NO), isoprene, and reactive oxygen species (ROS) predates life on Earth. Isoprene-ROS-NO interactions became relevant to climate chemistry when isoprene-emitting diatoms and angiosperms dominated aquatic and terrestrial ecosystems. NOx is a dangerous biogenic atmospheric pollutant, while isoprene acts as an antioxidant and hormone 'enabler' in plants. Isoprene-NO interactions vary among plant species and can impact growth and stress responses in a future NO-rich climate.

Summary: This review provides an update on recent advances in grafting and discusses potential new applications in agriculture. Grafting is a traditional horticultural technique that utilizes plant wound healing mechanisms to join two different genotypes into one plant. Recent studies have challenged previous beliefs about grafting monocotyledonous plants and the compatibility between different scion/rootstock combinations, opening up new possibilities for research and applications in agriculture. The review focuses on describing and evaluating these recent advances, particularly the molecular mechanisms behind graft union formation and genotypic compatibility.

Summary: Plant cell walls, composed of polysaccharides, provide support and enable growth. Recent research has made significant progress in understanding cell wall synthesis, including the identification and study of enzymes, the development of tools, and structural information generation. However, many questions about plant cell wall polysaccharide synthesis remain unanswered. This article discusses these questions, reviews supporting data, and explores potential technological advancements for future answers.

Summary: Nanomaterials have unique effects on plants, which can be explained on spatial and time scales. They modify the composition and structure of cell walls and membranes, promoting internalization. Effects of nanomaterials on plant growth and metabolism occur at the organ and organism levels. Nanomaterials also interact with beneficial ecological plant partners, with varied effects on different organisms. Understanding of the bidirectional relationship between plants and nanomaterials is of great relevance.

Summary: The importance of multidisciplinary and multispecies approaches is demonstrated through the review of apical dominance and shoot branching research. Different research methods have revealed the physiological process of apical dominance and the discovery of novel plant hormones. Further exploration of the whole network is needed to address challenges like sustainable food supply and climate change.

Summary: This review summarizes the physiological roles and potential molecular functions of late embryogenesis abundant (LEA) proteins in plants and other organisms. The structure-function relationship of LEA proteins, including their state in solution, self-assembly, and liquid-liquid phase separation, is also discussed. Furthermore, the promising potential of LEA proteins in biotechnological and agronomic applications is highlighted.

Summary: This review discusses the N-terminal modifications and their associated processing machinery in organisms with plastids gained through primary or secondary endosymbiosis. The N-terminus is a frequently modified site of proteins. Drawing primarily from knowledge gained from land plants, this review provides an overview of the modifications that alter protein N-terminal residues and presents updated information about the associated machinery, including the machinery in Archaeplastida. These modifications include various proteolytic events as well as additions of small groups such as acylation, arginylation, and oxidation. The landscape of N-terminal modifications dedicated to plastids is more complex compared to that of mitochondria. In addition, this review extends to plastid-containing Chromalveolata, including Stramenopiles, Apicomplexa, and Rhizaria. A well-conserved machinery, especially in the plastid, is reported. Examination of the two most abundant proteins on Earth, Rubisco and actin, reveals the complexity of N-terminal modification processes. The transfer of genes from the plastid to the nuclear genome during evolution is exemplified by the N-terminus modification machinery, which appears to be one of the latest transferred to the nuclear genome along with crucial major photosynthetic landmarks. This is supported by the greater number of plastid genes in Paulinellidae and red algae, which are the most recent and fossil recipients of primary endosymbiosis.

Summary: This review provides a historical overview of biogenic plastid signals, their role in chloroplast biogenesis, and presents a coherent working model based on current knowledge. The coordination between nucleus and plastid signals, termed anterograde and retrograde, is crucial for chloroplast biogenesis and seedling development. However, the molecular nature, transport, targets, and signaling function of these signals are still under debate. Recent studies propose a feedback mechanism between plastid and cytosolic protein homeostasis and dual-localized nucleo-plastidic proteins for coordinating chloroplast biogenesis with light-dependent control of seedling development.
