Cultivating the Next Generation: Early Career Researchers at the Forefront of Plant Science

Abstract

Scientific exploration is a relay race across generations. From Darwin's observations on plant movement and adaptation, to Mendel's elucidation of fundamental genetic principles using peas, to the modern molecular dissection of plant stress response mechanisms, every advance has depended not only on the strategic vision of established scientists but on their mentorship of young scholars and graduate students in the laboratory as well. It is this intergenerational transmission that enables each generation of researchers to revisit problems and questions with new tools, building on prior knowledge and continually pushing the boundaries of inquiry. Within this chain of succession, one group is critically important yet often overlooked. This group is Early Career Researchers, or ECRs. As defined for this Special Issue, ECRs are investigators who have obtained their PhD within the last 7 years and are under 40 years of age. They are the backbone of daily laboratory operations, deeply involved in experimental design, data acquisition, and technical problem solving. They are adept at emerging technologies and possess a practical understanding of the strengths and limitations of modern research tools. Although ECRs perform the majority of the research execution in most teams, their opportunities to publish as corresponding authors are often limited, and their independent academic identity is frequently intertwined with the guidance of senior mentors. This situation constrains their own career development to some extent and, at the same time, hinders the field from fully benefiting from diverse perspectives and fresh ideas, precisely the kind of vitality that sustains disciplinary progress. Recognizing the importance of identifying and supporting early career talent, several plant science journals under Wiley, including JIPB, Nordic Journal of Botany, Food and Energy Security, Plant Environment Interactions, and our own Plant, Cell and Environment, jointly launched this Special Issue on Early Career Researchers in Focus, Breakthroughs in Plant Science in August 2024. The response was overwhelming, reflecting the remarkable creativity of researchers at this career stage. Over the past 2 years, PCE received over 100 submissions. Following rigorous peer review, 28 papers were ultimately accepted for publication. This Special Issue serves both as a showcase of ECRs' scientific contributions and as a concrete effort to build an academic platform for them. The breadth of research covered in this issue is truly impressive, reflecting the multifaceted nature of modern plant science, ranging from macroecology to molecular mechanisms. Thematically, the papers encompass everything from global-scale ecological surveys to local physiological adaptation mechanisms. Methodologically, they extend from traditional physiological measurements to cutting-edge deep learning applications and CRISPR gene editing technologies. The issue comprises 23 original research articles, 2 brief communications and 3 review articles, covering topics such as volatile-mediated plant defense (Li et al. 2026), the molecular regulation of anthocyanin biosynthesis in apple under low nitrogen (Meng et al. 2026), and transgene-free genome editing in trees using CRISPR ribonucleoproteins (Ramakrishnan et al. 2025). Several contributions integrate or synthesize multi-omics evidence to reveal novel molecular mechanisms, including the role of lysine acetylation in plant immunity (Villette et al. 2025) and lipidome reprogramming that enhances photosynthetic performance (Deepa et al. 2026). These works are not merely incremental advances; they also propose new conceptual frameworks, for example by revealing a universal genome size–cell size relationship across land plants (Mir-Rosselló et al. 2025) and demonstrating the decoupling of water and nitrogen translocation from subsoil to the canopy in forest trees (Mrak et al. 2025). By bringing these outstanding contributions together in a single collection, this Special Issue serves both to highlight the remarkable contributions of ECRs and to inspire future discoveries. We are confident that these emerging leaders will continue to shape the trajectory of plant science, and we hope this issue serves as an entry point for readers to appreciate their exceptional research.
