Eleanor leaves for Bristol University

Filed under: Diary,Not extinct — John Allen @ 6:03 pm

Among a large class of 2018, on September 22nd Bristol University received our youngest daughter, Eleanor, to read Zoology. We wish her well. It’s a great place, and she is a multi-talented young lady.

16th International Symposium on Phototrophic Prokaryotes

University of British Columbia, Vancouver, Canada, 5 – 9 August 2018

This was a fine meeting with many reports of first-rate new research. My own contribution was entitled Two-component redox regulatory control in the origins of oxygen evolution, cyanobacteria, and chloroplasts. Some photos… The first is a remarkable UBC memorial. The last is the location of the banquet, in the Museum of Anthropology.

I was surprised and pleased to find my simple graphic on the cover of the journal Physiologia Plantarum.

The special issue.

The conception of Queen Mary, University of London

Quoting “ALL SORTS AND CONDITIONS OF MEN” by Walter Besant.

There was so much to cherish, and to maintain. Let us hope for future reconception.

Today is our wedding anniversary. This year it happens to be fathers’ day, too.
To love and be loved.
How lucky am I.

Enhancing photosynthesis in crop plants: targets for improvement

October 10 and 11, 2016.

Contributors presented interesting new findings, approaches and techniques, while the outlook and prospect of “enhancing photosynthesis” seems not to have changed significantly over many years. Crop plants rely totally on the same photosynthetic mechanisms as those used by all plants, and some bacteria. I like the idea of tinkering with these machines to see what might be done. Totally unexpected results, rather than targets, will be the most useful. Important discoveries and new possibilities always arise from a problem in understanding, and from thinking of ways to solve it. There were definitely some important problems, good ideas, and experimental tests freely reported at the meeting. Some were very good indeed. I shall comment on these. It was unfortunate that the meeting opened with an unscheduled ten minutes intelligible only to those already aware of some sort of bid for funding, thus excluding most of those present.  I was happy to be in the majority on this.

There is progress – resting always on the possibility of ideas being open to examination and criticism.

The 13th International Colloquium on Endocytobiology and Symbiosis, Kyoto

Filed under: Diary,Not extinct — John Allen @ 4:13 pm

The 13th International Colloquium on Endocytobiology and Symbiosis was held in Kyoto from September 10 to 14, 2016. A fine poster advertised the colloquium.

The organiser was Junichi Obokata of Kyoto Prefectoral University. My painstakingly generous local host was Mitsumasa Hanaoka of Chiba University. I am so grateful to them both, as to the colloquium staff and fellow participants.

At Mitsumasa’s invitation I gave a seminar in his laboratory in Chiba, immediately after getting off the train from Narita airport on 8 September, and a longer and better version on 9 September at Kyoto University. Both seminars were entitled Mitochondria, ageing and separate sexes, and elicited excellent questions.

My plenary lecture at the colloquium itself was an account of progress with a consistent theme over a number of years and in different laboratories, countries, and universities, including recent results published in 2016. This lecture was entitled Why chloroplasts and mitochondria retain their own genomes and genetic systems: Co-location for Redox Regulation of gene expression.

The full programme of the Colloquium is available, and includes abstracts.

Photosynthetic and Respiratory complexes: from structure to function

Filed under: Diary,Not extinct — John Allen @ 4:06 pm

Photosynthetic and Respiratory complexes: from structure to function in Verviers, Belgium, from August 13 to 16, 2016. A satellite conference organised by Egbert Boekema and Pierre Cardol. The programme was full of interest.

I gave a Plenary Lecture soon after arrival: Redox control of thylakoid protein phosphorylation and reaction centre gene transcription. Molecular recognition redistributes mobile light-harvesting antennae and adjusts the stoichiometry of photosystems I and II.

The 17th International Congress on Photosynthesis Research, Maastricht

Filed under: Diary,Not extinct — John Allen @ 3:55 pm

The 17th International Congress on Photosynthesis Research. Photosynthesis in a Changing World took place in Maastricht, The Netherlands, from 7 to 12 August 2016. The organisers were Roberta Croce and Herbert van Amerongen.

My own contribution, in the session Evolution of Photosynthesis, was about photosynthesis in a radically changing world. It was entitled Conserved two-component transcriptional redox regulation in cyanobacteria and chloroplasts. Implications for the origin and evolutionary trajectory of oxygenic photosynthesis.

The full programme of the Congress.
