Celebrating the Diamond Anniversary of the Journal of Experimental Botany
In the world of science, where new journals emerge with every shifting trend, sustaining a publication for 75 years is a monumental achievement. It speaks to a legacy of quality, community, and enduring relevance. The Journal of Experimental Botany (JXB), founded in 1950, has reached this remarkable diamond anniversary, a milestone that mirrors the sturdy, long-lived growth of the very organisms it studies 5 .
From its roots in the Society for Experimental Biology, JXB has grown into a mature, internationally recognized journal that supports a diverse and global community of plant scientists 5 . Its history, as the journal itself suggests, can be likened to the lifetime of a tree: it began as the "seed of an idea" and has since expanded into a towering presence that supports and nurtures the entire ecosystem of plant research 1 .
As we celebrate this legacy, we also look to the future, exploring how the groundbreaking research published in its pages is helping to solve some of humanity's most pressing challenges, from food security to climate change.
The story of JXB is inextricably linked to the post-war expansion of scientific inquiry. Established by the Society for Experimental Biology (SEB), its mission was to meet the needs of a burgeoning community of experimental plant biologists 5 . While its roots were British, its outlook was always international, quickly becoming a premier destination for high-quality plant research from across the globe.
JXB boasts a Journal Impact Factor of 5.6 and is ranked 25th out of 265 journals in the 'Plant Sciences' category 4 .
To mark its 75th anniversary, JXB is hosting a special symposium in Edinburgh in September 2025. The meeting's structure reflects the journal's own life cycle, with sessions organized around the themes of "Beginnings, Growing and Maturity," before finally looking to the "Future" and the challenges of the next 25 years 1 .
This event is more than a celebration; it is an active effort to "build links between people and research communities" and "inspire ideas to help the next generation" 1 . It embodies the journal's commitment to not just documenting scientific progress, but to actively fostering it.
To capture the state of plant science in 2025, JXB commissioned a special series of its flagship Darwin Reviews from leading scientists 5 . These comprehensive articles provide a panoramic view of the field, from molecular mechanisms to global agricultural challenges.

The anniversary collection highlights the diverse yet interconnected nature of modern plant science, with significant emphasis on stress resilience and molecular foundations.
Among the critical reviews in the anniversary collection, one titled "Building climate-resilient crops: genetic, environmental, and technological strategies for heat and drought stress tolerance" stands out for its immediate global relevance 5 . Authored by Prado and colleagues, this work synthesizes strategies to safeguard our food supply.
Let's walk through a simplified version of the methodology a researcher might use to contribute to this vital field, with the ultimate goal of identifying a gene that confers heat tolerance.
The process begins by screening a diverse population of a crop plant, such as tomato or wheat. This population includes many different varieties, each with slight genetic variations. Researchers expose young plants to controlled heat stress and identify the individuals that perform best (the "heat-tolerant" lines).
Scientists then use genomic tools to compare the DNA of the tolerant and susceptible plants. They look for genetic markers that are consistently present in the tolerant plants. This process, known as quantitative trait locus (QTL) mapping, helps narrow down the location of the gene(s) responsible for the trait.
Once a candidate gene is identified, its function must be validated. Researchers might use CRISPR gene-editing to "knock out" the gene in a tolerant plant to see if it becomes heat-sensitive. Conversely, they might insert the gene into a susceptible plant to see if it becomes more tolerant.
With the gene identified, scientists study the physiological mechanisms it controls. Does it produce a protein that protects other proteins from denaturing? Does it activate a network of other protective genes? This step confirms the biological pathway through which the gene operates.
Finally, plants with the validated gene are grown in real-world field conditions across multiple seasons and locations to ensure the trait improves yield under heat stress without negatively impacting other agricultural traits.
Imagine an experiment where researchers have identified a candidate gene, PlWRKY31, and used virus-induced gene silencing (VIGS) to reduce its expression in herbaceous peony to test its function in heat tolerance . The results could be visually and quantitatively striking.
| Plant Type | Leaf Wilting | Leaf Chlorosis (Yellowing) | Overall Plant Viability |
|---|---|---|---|
| Control Plant | Minimal | Slight | High |
| PlWRKY31-Silenced Plant | Severe | Extensive | Low |
| Gene Name | Expression in Control Plants | Expression in Silenced Plants | Implied Function |
|---|---|---|---|
| HSP17.6 | High | Low | PlWRKY31 is required for HSP17.6 activation |
| HSP70 | High | Very Low | PlWRKY31 is a key activator of HSP70 |
| HSP90 | Moderate | Low | PlWRKY31 significantly upregulates HSP90 |
This integrated analysis proves the gene's importance. The silenced plants, unable to activate their full heat-shock response, succumb to stress, while the control plants survive. This discovery, as highlighted in the JXB anniversary reviews, is exactly the kind of fundamental knowledge needed to develop "climate-resilient crops" 5 .
Modern plant science relies on a sophisticated array of tools to dissect complex traits like heat tolerance.
A rapid method to "knock down" gene expression without permanent transgenic plants.
Allows for precise, heritable knockout or modification of specific genes.
Measures expression levels of specific genes in response to stress.
Enables whole-genome sequencing and transcriptome analysis.
The 75th anniversary of the Journal of Experimental Botany is more than a look back at past accomplishments. It is a testament to the vibrant, ongoing journey of plant science. The research highlighted in its diamond anniversary collection—from the molecular dance of nucleotides to the global pursuit of climate-resilient crops—demonstrates a field that is both deeply fundamental and urgently applied.
As the journal's symposium looks to the future, it acknowledges the "challenges of the next 25 years" 1 . With the world's population growing and the climate changing, the work published in JXB has never been more critical.
The journal, like a well-established tree, provides a strong foundation from which the next generation of scientists can reach even higher. The next 25 years of discovery will be crucial, and with the solid roots of 75 years of excellence, the Journal of Experimental Botany is poised to continue its vital role in supporting the community that will make those discoveries happen.
