Education edit

Leaver was educated at Lyme Regis Grammar School and Imperial College London[5] where he was awarded a Bachelor of Science degree (first class) followed by a PhD in plant physiology in 1966.[6]

Career and research edit

Leaver's area of expertise is in plant biochemistry, development, plant physiology and signalling;[7][12][13] before his current positions, he has at the Department of Botany and Plant Pathology at Purdue University[14] and the University of Edinburgh.[15][16] During his career, Leaver held the following positions:

Awards and honours edit

Leaver was elected a Fellow of the Royal Society (FRS) in 1986.[18] His nomination reads:

Distinguished for his contributions to unravelling the role of nucleic acids in the development of higher plants. Leaver was the first person to isolate nucleic acids from higher plants in 1964, and produced the first description of the pathway of cytoplasmic ribosomal RNA synthesis. He discovered a novel species of 4.5S RNA in chloroplast ribosomes, and with W, Bottomley developed the coupled transcription-translation system now used in the analysis of chloroplast DNA. He established that the synthesis of glyoxysomal enzymes in cucumber seedlings is under transcriptional control. His more recent and innovative work concerns the structure, information content and expression of the plant mitochondrial genome, a field he has pioneered. He was the first to isolate plant mitochondrial ribosomes, establish their unique RNA composition, and develop the standard system now used for protein synthesis by isolated plant mitochondria. His work has produced strong evidence linking the agriculturally important trait of cytoplasmic male sterility in maize and sorghum with mutations in the mitochondrial genome which lead to the production of variant polypeptides. As well as isolating several protein-encoding plant mitochondrial genes, he has identified, cloned and sequenced the first nuclear gene for a plant mitochondrial protein.[18]

Leaver was also awarded EMBO Membership in 1982,[1] elected a member of the Academia Europaea in 1989[19] and appointed Commander of the British Empire (CBE) in the 2000 New Year Honours.[5]

Personal life edit

Leaver's Who's Who entry lists his recreations as “walking and talking in Upper Coquetdale” in Northumberland.[5]
