Yesterday, I received the sad news that my dear friend and former colleague at the International Rice Research Institute (IRRI), John Sheehy, had passed away on 7 June after battling Parkinson’s Disease and Multiple System Atrophy (MSA) for several years. He was just 76.
I first met John in 1995, when he applied for the position of Systems Modeller at IRRI. I was Chair of the Search Committee. John came to IRRI after a successful career at the Grassland Research Institute (GRI) in Hurley, Berkshire, until it closed in 1992. His groundbreaking (and award-winning) work at GRI on nodulation, gaseous diffusion, and nitrogen fixation in grassland legumes, and other aspects of crop physiology focused on yield potential.
I knew the first time I spoke with John he was someone who would bring a very different scientific perspective to IRRI’s research. And that’s just what he did. He wasn’t some fresh-faced graduate or postdoc expected to toe the line in terms of rice science orthodoxy, so to speak. Always polite, he often challenged the perspectives and approaches of some IRRI old timers who couldn’t (or wouldn’t) appreciate John’s breadth of quantitative expertise. He had graduated with a BSc degree in Physics, completed an MSc in Electronics, and then studied for his PhD in ecophysiology under Professor John Cooper, CBE FRS at the Welsh Plant Breeding Station in Aberystwyth.
In coming to IRRI, he led research on and supported breeding the so-called New Plant Type (NPT) that was expected to push the yield barrier in rice.
Setting up the Applied Photosynthesis and Systems Modeling Laboratory, John came to the conclusion that a completely new approach was needed if rice yields were to be increased significantly. That’s because photosynthesis in rice (known as C3 photosynthesis) is inefficient compared to the system (C4) in other cereals like maize. John began to develop ideas to turbocharge photosynthesis by introducing ‘C4’ traits into rice, thereby aiming to increase photosynthetic efficiency by 50%, as well as improve nitrogen use efficiency, and double water use efficiency.
Rather than me trying to explain the rationale for this vision, why not listen to John explaining the need for a C4 rice.
John appreciated that IRRI could not realize this dream of a C4 rice alone. So he set about persuading, and bringing together, a group of many of the best scientists worldwide in a C4 Rice Project, that is partly funded by the Bill & Melinda Gates Foundation. The continuing Project is an important part of John’s scientific legacy.
It is now coordinated by Professor Jane Langdale, CBE FRS at the University of Oxford.
At the time of his death, and after 20 years of research, C4 rice is not yet a reality, but significant progress has been made.
John’s scientific output was prodigious, and his many publications appeared in some of the best rated journals in his field, like Field Crops Research for example, a reflection of his research stature at IRRI (and before he joined IRRI). You can check his publications on Google Scholar.
He also waded enthusiastically into the controversy over the System of Rice Intensification or SRI, questioning—based on solid quantitative analysis of yield potential in rice—the yield claims of SRI adherents.
John retired in 2009 and returned to the UK. Before leaving IRRI, he met with Gene Hettel (former Head of IRRI’s Communication and Publications Services, and ‘IRRI Historian’) to record his thoughts on rice science and the challenges that IRRI would face.
In 2012, John was recognized in the New Year Honours (see page N.24) with an OBE for services to agricultural research and development, which was conferred during an investiture at Buckingham Palace on 14 February.
In July 2014, John was honoured as a Fellow of his alma mater, Aberystwyth University.
In 2011, Steph and I joined John and Gaynor’s many friends and relatives to celebrate their 40th wedding anniversary.
While at IRRI, John had taken enthusiastically to golf, and could be seen almost every weekend out on the golf course south of Los Baños where he had become a member. On his retirement to the UK, he was unfortunately unable to continue with this passion, due to bouts of poor health.
After I retired in 2010 back to the UK, John and I kept in touch regularly by email, on the phone, or SMS, when either Wales or Ireland were doing well at rugby, especially in the Six Nations championship. He had divided loyalties, born in Wales of Irish ancestry.
The last time I saw John was in July 2017, when Steph and I spent the weekend with him and Gaynor in Marlow, and met up with other IRRI friends, Graham and Sue McLaren (who now reside in Canada),
It was also an opportunity for John and me to swap OBE investiture reminiscences. I had also been made an OBE in the same New Year Honours as John, but attended an investiture two weeks later on 29 February.
John was a far better scientist than I could ever aspire to be. I always sought his advice on science issues. In return, he asked my advice about how to manoeuvre through institute politics and management to influence his research agenda, especially after I had moved upstairs, so to speak, to join IRRI’s senior management team.
But what I remember most about John was his cracking, but rather dry, sense of humor. His generosity of spirit. He was an excellent host. Many’s the dinner or BBQ Steph and I enjoyed with John, at his house or ours.
John, you will be sadly missed. Rest in Peace!
