Environmental adaptation of plants through the concert of synthesis and degradation of biomolecules
Living organisms acquire nutrients from their environment to build their bodies, while at the same time, the components within their bodies are continuously degraded and recycled back into nature.
Organisms skillfully regulate the balance between synthesis and degradation to maintain a dynamic equilibrium, but many of the molecular mechanisms underlying this balance remain unknown.
Increasing crop biomass is directly linked to improving agricultural production. Understanding the synthesis and degradation processes in plants and elucidating the molecular mechanisms that regulate them, we can apply this knowledge to control the equilibrium state, potentially leading to more efficient agriculture.
I have focused on autophagy, an intracellular mechanism of self-degradation, to clarify how plants degrade their own components in order to adapt to diverse environmental conditions.
In particular, under nutrient stress conditions where the balance of available nutrients is disrupted, plants must precisely coordinate degradation and synthesis to maintain an appropriate equilibrium status and support further growth.
I aim to reveal how plants sense their nutrient status and regulate uptake, transport, and metabolism of nutrients, leading to a comprehensive understanding of these processes in relation to degradation mechanisms.
Educational approach
Skills gained through research experience for survival in modern society
In research, we generate ideas, develop hypotheses, and conduct experiments to test those hypotheses.
However, many experiments do not proceed as planned, requiring careful analysis of the problems, consideration of countermeasures, and repeated challenges.
Through such trial and error, results are obtained, but completing research requires publishing a paper that summarizes these findings.
This process must be accomplished within a limited timeframe and budget.
One of the abilities acquired through research is creativity to generate interesting ideas.
Implementing the ideas requires planning and communication skills to effectively convey them to others.
Furthermore, during the experimental phase, autonomy, management skills, and stress management ability are granted.
When summarizing results, skills such as logical writing, effective presentation, and public communication are enhanced.
Individuals with these abilities have the poteintial not only to work as researchers contributing to academic advancement by applying advanced expertise at research institutions, but also to play important roles in society as individuals capable of independently acquiring and analyzing information and acting based on their convictions.
Vision for industry-academia collaboration
Uncovering the various physiological roles of intracellular degradation and sowing the seeds of future technologies
In recent years, impaired autophagy has been identified as a cause of various human diseases, promoting the exploration of therapies that target autophagy.
By contrast, technological developments in the field of plant science have been slower.
I have revealed that autophagy contributes to the suppression of zinc deficiency in plants (doi: 10.1104/pp.19.01522) and to the extension of seed storage longevity (doi: 10.1073/pnas.2321612121).
These findings are expected to contribute to the development of crops cultivable in zinc-deficient soils and technologies for long-term seed storage.
Currently, I aim to elucidate the molecular mechanisms by which plants sense nutrient status, regulate nutrient uptake and transport, and adjust their metabolism, as well as to understand the relationship between these mechanisms and the mechanisms regulating the intracellular degradation of biomolecules.
My research has the potential to enable the development of biomass-increasing techniques by controlling the amount of substances present in crops.
I sincerely hope that those in companies and industrial sectors take an interest in the insights generated by basic scientists and explore ways to apply them to society.
