Nicola Jane Spence CBE (born 22 February 1961 [1] ) is the Chief Plant Health Officer and Deputy Director for plant and bee health at the Department for Environment, Food and Rural Affairs.
Spence was educated at The Mount School, York and Bridlington School. [2] She obtained a BSc degree in Botany from the University of Durham. [3] Before starting her Master's degree, Spence volunteered at the Bermuda Marine Biology Research Institute then worked as a tutor for O level and A level students, and was unsure whether she wanted to pursue a career in research. [4] Spence undertook an MSc degree in Microbiology from Birkbeck College, [3] which she states 'turned out to be the best decision I made at the start of my career.' [4] Spence then obtained a PhD degree in Plant Virology from the University of Birmingham; [3] her thesis was entitled The identification, distribution and ecology of bean common mosaic virus in Africa. [5]
In December 2018 Spence represented the University of Birmingham on the Christmas edition of University Challenge . [6]
Spence was a scientific researcher in plant virology at Horticulture Research International and Fera. She has researched viral diseases of crops and horticulture both in Africa and the UK.
Her research into viral diseases of crops in Africa has included investigations into the pathogenicity of bean common mosaic virus [7] and its occurrence in legumes in Uganda. [8] She has also published on the economic impact of turnip mosaic virus, cauliflower mosaic virus and beet mosaic virus in Kenya [9] and patterns of plant pest introductions into Europe and Africa. [10] She was the vegetables technical advisor for the Department for International Development's crop protection programme, [11] leading projects on management of viral diseases in vegetable crops in Kenya [12] and promotion of quality kale seed in Kenya. [13]
In UK horticultural systems, Spence has worked on identifying viruses present in Alstroemeria crops in the UK, [14] as well as isolating and characterising viruses from petunia [15] and Cineraria . [16] Other research included studying the effect of pepino mosaic virus on tomato yield. [17] She was an editor and contributor to the book Biotic Interactions in Plant-pathogen Associations. [18] and she was previously a member of the editorial board for the scientific journal Plant Pathology .
Spence was appointed chief scientist at Fera in 2009. [4]
In 2009 Spence was appointed the chief executive of Science City York, [2] later known as SCY, an organisation supporting the development of science and technology industries in York, England. [19] In this role, Spence promoted connections between academics and local businesses, managing events such as Venturefest. [20] She was key in the development of the concept of the BioVale, [21] which aims to promote the bioeconomy in Yorkshire and the Humber. [22] She remained in the role for four years, until her appointment as Chief Plant Health Officer. [21]
Spence took up her post as chief plant health officer in April 2014, [23] and later also became deputy director for plant and bee health.
Spence has made several media appearances in relation to her work at Defra. In April 2016 she appeared on the Today Programme to discuss the finding of a resistant ash tree in Norfolk, [24] and has also appeared on the BBC's Countryfile programme. She has also been a guest on Farming Today discussing tree diseases in the UK. [25] In 2016, she was involved in the management of the Asian hornet outbreak response, [26] [27] and appeared on the World at One to explain Asian hornet biology and the Defra response to the outbreak. [28]
In 2017, in response to the Xylella fastidiosa outbreak in several European countries, Spence wrote to the horticulture sector urging them to follow the example of those which had committed not to bring in host plants from the affected countries. [29] [30] In 2018, she was a guest and speaker at summit examining the risks posed by Xylella to the horticulture industry hosted by Prince Charles. [31]
In May 2018, Spence gave evidence to the EU Select Committee on Brexit and the potential implications for plant health. [32]
Whilst at Defra, Spence has been active in promoting plant health as a career. In conjunction with the Royal Society of Biology and Charles Lane at Fera Science, Spence developed the Plant Health Professional Register – a way for those working in the area of plant health to gain a formal recognition of their professional skills and continue their professional development. [33] She worked with Harper Adams University to put together a course on plant biosecurity, and is a visiting professor at the university. [34]
Spence was appointed Commander of the Order of the British Empire (CBE) in the 2022 New Year Honours for services to plant health. [35]
Spence has previously served on the Board of Trustees for Kew Gardens. [36] She is currently a Trustee for The Yorkshire Arboretum [37] and a Fellow of the Royal Society of Biology.
Spence is a visiting professor in plant pathology at Harper Adams University. She sits on the board of governors at her former school in York, The Mount. [38] and a member of the University of York Court. [39] She is Vice-President of the British Society for Plant Pathology. [3] Spence is chair of the management board of the CONNECTED project that aims to tackle vector borne plant diseases in Africa. [40]
The mung bean or green gram is a plant species in the legume family. The mung bean is mainly cultivated in East, Southeast and South Asia. It is used as an ingredient in both savoury and sweet dishes.
Lettuce mosaic virus (LMV) is a typical potyvirus, which causes one of the major virus diseases of lettuce crops worldwide.
Xylella fastidiosa is an aerobic, Gram-negative bacterium of the genus Xylella. It is a plant pathogen, that grows in the water transport tissues of plants and is transmitted exclusively by xylem sap-feeding insects such as sharpshooters and spittlebugs. Many plant diseases are due to infections of X. fastidiosa, including bacterial leaf scorch, oleander leaf scorch, coffee leaf scorch (CLS), alfalfa dwarf, phony peach disease, and the economically important Pierce's disease of grapes (PD), olive quick decline syndrome (OQDS), and citrus variegated chlorosis (CVC). While the largest outbreaks of X. fastidiosa–related diseases have occurred in the Americas and Europe, this pathogen has also been found in Taiwan, Israel, and a few other countries worldwide.
Cassava mosaic virus is the common name used to refer to any of eleven different species of plant pathogenic virus in the genus Begomovirus. African cassava mosaic virus (ACMV), East African cassava mosaic virus (EACMV), and South African cassava mosaic virus (SACMV) are distinct species of circular single-stranded DNA viruses which are transmitted by whiteflies and primarily infect cassava plants; these have thus far only been reported from Africa. Related species of viruses are found in India and neighbouring islands, though cassava is cultivated in Latin America as well as Southeast Asia. Nine species of cassava-infecting geminiviruses have been identified between Africa and India based on genomic sequencing and phylogenetic analysis. This number is likely to grow due to a high rate of natural transformation associated with CMV.
Barley yellow mosaic virus is plant pathogenic virus that causes the yellow mosaic disease of barley. Its shape is categorized as being flexuous filamentous, with lengths of 275 and 550 nanometers. The virus has a limited host range, and barley appears to be the only known susceptible host. The virus is transmitted via Polymyxa graminis, which is a plasmodiophorid protist, through the resting spores that survive in the soil, and eventually zoospores. Eastern Asia is the most affected region, but the virus can be found worldwide. Current agricultural practices have been ineffective at eliminating the virus, but breeding resistance appears to be the only way to help reduce the disease.
Bean pod mottle virus, or BPMV, is a species of plant pathogenic virus in the family Secoviridae. It is known to infect soybean crops.
Cucumber mosaic virus (CMV) is a plant pathogenic virus in the family Bromoviridae. This virus has a worldwide distribution and a very wide host range, having the reputation of the widest host range of any known plant virus. It can be transmitted from plant to plant both mechanically by sap and by aphids in a stylet-borne fashion. It can also be transmitted in seeds and by the parasitic weeds, Cuscuta sp. (dodder).
Soybean mosaic virus (SMV) is a member of the plant virus genus Potyvirus. It infects mainly plants belonging to the family Fabaceae but has also been found infecting other economically important crops. SMV is the cause of soybean mosaic disease that occurs in all the soybean production areas of the world. Soybean is one of the most important sources of edible oil and proteins and pathogenic infections are responsible for annual yield losses of about $4 billion in the United States. Among these pathogens, SMV is the most important and prevalent viral pathogen in soybean production worldwide. It causes yield reductions of about 8% to 35%, but losses as high as 94% have been reported.
Sugarcane mosaic virus (SCMV) is a plant pathogenic virus of the family Potyviridae. The virus was first noticed in Puerto Rico in 1916 and spread rapidly throughout the southern United States in the early 1920s. SCMV is of great concern because of the high economic impact it has on sugarcane and maize.
Elsayed Elsayed Wagih PhD, DIC, CIDTT is an Egyptian professor of virology and biotechnology and vice President of the Arab Society for Biotechnology. He was born in Alexandria, Egypt. Wagih is well known for having invented Zymoblot, the fastest available microtechnique to detect gene expression and/or enzyme activity in any biological specimen as well as the ”Mirror Image in vivo electro-blotting technique” that detects virus particles or any foreign protein in any tissue. He also discovered two viruses reported under his name in the world data bank of viruses, the first was named "Peanut Chlorotic Ringspot Virus (PCRV)" and the second was called “Peanut Top Paralysis (PTPV)".
Orthotospovirus is a genus of negative-strand RNA viruses, in the family Tospoviridae of the order Bunyavirales, which infects plants. Tospoviruses take their name from the species Tomato spotted wilt orthotospovirus (TSWV) which was discovered in Australia in 1919. TSWV remained the only known member of the family until the early 1990s when genetic characterisation of plant viruses became more common. There are now at least twenty species in the genus with more being discovered on a regular basis. Member viruses infect over eight hundred plant species from 82 different families.
Agriculture in Kenya dominates Kenya's economy. 15–17 percent of Kenya's total land area has sufficient fertility and rainfall to be farmed, and 7–8 percent can be classified as first-class land. In 2006, almost 75 percent of working Kenyans made their living by farming, compared with 80 percent in 1980. About one-half of Kenya's total agricultural output is non-marketed subsistence production.
Alternanthera mosaic virus (AltMV) is a plant pathogenic virus. AltMV belongs to the virus genus Potexvirus and the virus family Alphaflexiviridae.
Lawrence Ogilvie was a Scottish plant pathologist who pioneered the study of wheat, fruit and vegetable diseases in the 20th century.
Nerine bowdenii is a species of flowering plant in the family Amaryllidaceae. It is an herbaceous bulbous perennial, growing to 45 cm (18 in) tall by 8 cm (3 in), with strap-shaped leaves and large umbels of lily-like pink flowers in late summer and autumn. The common names of the species are Cornish lily, Cape flower, Guernsey lily, and Bowden lily. However, it is neither a true lily nor from Cornwall or Guernsey, but originates from South Africa. Confusingly the name “Guernsey lily” is also applied to a related species, Nerine sarniensis.
Aphis nerii is an aphid of the family Aphididae. Its common names include oleander aphid, milkweed aphid, sweet pepper aphid, and nerium aphid.
Maize lethal necrosis disease is a viral disease affecting maize (corn) predominantly in East Africa, Southeast Asia and South America, which was recognised in 2010. It is caused by simultaneous infection with two viruses, MCMoV and any of several Potyviridae.
Frances Joan Harvey Moore, OBE was a British plant pathologist, science administrator and conservationist.
Elijah Miinda Ateka is a Professor of Plant Virology at the Jomo Kenyatta University of Agriculture and Technology. He is involved with the diagnosis and characterisation of the sweet potato virus and the cassava virus, and is part of the Cassava Virus Action Project (CVAP).
The Ash Archive is a project founded in 2019 to restore ash trees to the landscape in England. English ash trees experienced massive dieback beginning in 2012 as a result of a fungal pathogen, Hymenoscyphus fraxineus. The archive contains over 3,000 trees, all of which propagated from the shoots of trees that had demonstrated some resistance to the fungus. The archive was established with £1.9 million in government funding, and followed a five-year project to identify ash trees that were resistant to the fungus. One of the final trees in the archive was planted in January 2020 by Nicola Spence, the Chief Plant Health Officer of the UK government. Spence said, "I'm delighted to acknowledge the successes of the Ash Archive project and welcome the International Year of Plant Health by planting an ash dieback-tolerant tree."
