Jane Alison Langdale, CBE FRS (born 1960) [1] is a British geneticist and academic. She is Professor of Plant Development in the Department of Biology at the University of Oxford [6] [7] and a Professorial Fellow at The Queen's College, Oxford. [8] [9] [10] [11] [12]
Langdale was educated at Barr's Hill Grammar School in Coventry [1] [8] and the University of Bath, where she was awarded a Bachelor of Science degree in Applied Biology in 1982, specialising in microbiology. [13] [3] [8] Her PhD was in human genetics [13] and carried out at St Mary's Hospital Medical School [8] and Charing Cross and Westminster Medical School [14] [15] and awarded by the University of London. [16]
Following her PhD, Langdale was employed for five years as a postdoctoral researcher at Yale University with Tim Nelson. [13] [17] She returned to the UK in 1990, to work in the Department of Plant Sciences (since 2022 the Department of Biology) where she has worked since. [13] Langdale's research interests [6] [7] [18] are in two main areas:
Langdale's research has been funded by the Biotechnology and Biological Sciences Research Council (BBSRC) [20] and has been published in leading peer reviewed scientific journals including Nature , [21] Science , [22] Current Opinion in Plant Biology , [23] Development , [24] Gene , [14] Trends in Genetics , [25] The Plant Cell , [26] [27] [28] Annual Review of Plant Biology , [29] Planta , [30] Plant Physiology , [31] Journal of Cell Science , [32] The EMBO Journal , [33] The Plant Journal, PLOS ONE [34] Genes & Development [5] and the New Phytologist . [35] [36] [37]
Langdale is the co-author of the book How to Succeed as a Scientist: From Postdoc to Professor [38] with materials scientist Barbara Gabrys. She featured on the BBC series, Plants: From Roots to Riches in 2014 with Kathy Willis. [39] [40]
Langdale was elected a Fellow of the Royal Society (FRS) in 2015. [41] Her certificate of election reads:
Jane Langdale has produced a body of work that has transformed our understanding of how plants make leaves and how leaves changed during major evolutionary transitions. The breadth of her research program has led to the elucidation of mechanisms operating throughout leaf development – from the earliest stages of organ inception and specification at the shoot apex, through patterning of distinct cell-types, to chloroplast biogenesis. She has done all of this in a comparative framework and has thus advanced our understanding of leaf development not just in model flowering plant species but in species from all major land plant lineages. [42]
Langdale was elected a member of the European Molecular Biology Organization (EMBO) in 2007 [2] and appointed Commander of the Most Excellent Order of the British Empire (CBE) in the 2018 Birthday Honours for services to Plant Science. [43] [44] She was awarded a Doctor of Science degree (DSc) honoris causa by the University of Bath in 2018. [3]
She was elected a foreign associate of the National Academy of Sciences of the United States in April 2019. [4]
She was elected a corresponding member of the Australian Academy of Science in 2020.[ citation needed ]
Langdale has always had Airedale Terriers [45] and is the elder sibling of the barrister Rachel Langdale King's Counsel (KC). [46] [47]
A chloroplast is a type of membrane-bound organelle known as a plastid that conducts photosynthesis mostly in plant and algal cells. The photosynthetic pigment chlorophyll captures the energy from sunlight, converts it, and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water in the cells. The ATP and NADPH is then used to make organic molecules from carbon dioxide in a process known as the Calvin cycle. Chloroplasts carry out a number of other functions, including fatty acid synthesis, amino acid synthesis, and the immune response in plants. The number of chloroplasts per cell varies from one, in unicellular algae, up to 100 in plants like Arabidopsis and wheat.
Photosynthesis is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism. Photosynthesis usually refers to oxygenic photosynthesis, a process that produces oxygen.
Photosynthetic organisms store the chemical energy so produced within intracellular organic compounds like sugars, glycogen, cellulose and starches. To use this stored chemical energy, an organism's cells metabolize the organic compounds through cellular respiration. Photosynthesis plays a critical role in producing and maintaining the oxygen content of the Earth's atmosphere, and it supplies most of the biological energy necessary for complex life on Earth.
A plastid is a membrane-bound organelle found in the cells of plants, algae, and some other eukaryotic organisms. Plastids are considered to be intracellular endosymbiotic cyanobacteria.
Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions that allows a plant to photosynthesize during the day, but only exchange gases at night. In a plant using full CAM, the stomata in the leaves remain shut during the day to reduce evapotranspiration, but they open at night to collect carbon dioxide and allow it to diffuse into the mesophyll cells. The CO2 is stored as four-carbon malic acid in vacuoles at night, and then in the daytime, the malate is transported to chloroplasts where it is converted back to CO2, which is then used during photosynthesis. The pre-collected CO2 is concentrated around the enzyme RuBisCO, increasing photosynthetic efficiency. This mechanism of acid metabolism was first discovered in plants of the family Crassulaceae.
C4 carbon fixation or the Hatch–Slack pathway is one of three known photosynthetic processes of carbon fixation in plants. It owes the names to the 1960s discovery by Marshall Davidson Hatch and Charles Roger Slack.

The ABC model of flower development is a scientific model of the process by which flowering plants produce a pattern of gene expression in meristems that leads to the appearance of an organ oriented towards sexual reproduction, a flower. There are three physiological developments that must occur in order for this to take place: firstly, the plant must pass from sexual immaturity into a sexually mature state ; secondly, the transformation of the apical meristem's function from a vegetative meristem into a floral meristem or inflorescence; and finally the growth of the flower's individual organs. The latter phase has been modelled using the ABC model, which aims to describe the biological basis of the process from the perspective of molecular and developmental genetics.
The evolution of plants has resulted in a wide range of complexity, from the earliest algal mats of unicellular archaeplastids evolved through endosymbiosis, through multicellular marine and freshwater green algae, to spore-bearing terrestrial bryophytes, lycopods and ferns, and eventually to the complex seed-bearing gymnosperms and angiosperms of today. While many of the earliest groups continue to thrive, as exemplified by red and green algae in marine environments, more recently derived groups have displaced previously ecologically dominant ones; for example, the ascendance of flowering plants over gymnosperms in terrestrial environments.

Evolutionary developmental biology (evo-devo) is the study of developmental programs and patterns from an evolutionary perspective. It seeks to understand the various influences shaping the form and nature of life on the planet. Evo-devo arose as a separate branch of science rather recently. An early sign of this occurred in 1999.

In molecular biology, the auxin binding protein family is a family of proteins which bind the plant hormone auxin. They are located in the lumen of the endoplasmic reticulum (ER). The primary structure of these proteins contains an N-terminal hydrophobic leader sequence of 30-40 amino acids, which could represent a signal for translocation of the protein to the ER. The mature protein comprises around 165 residues, and contains a number of potential N-glycosylation sites. In vitro transport studies have demonstrated co-translational glycosylation. Retention within the lumen of the ER correlates with an additional signal located at the C terminus, represented by the sequence Lys-Asp-Glu-Leu, known to be responsible for preventing secretion of proteins from the lumen of the ER in eukaryotic cells.
In molecular biology mir-390 microRNA is a short RNA molecule. MicroRNAs function to regulate the expression levels of other genes by several mechanisms.
The evolution of photosynthesis refers to the origin and subsequent evolution of photosynthesis, the process by which light energy is used to assemble sugars from carbon dioxide and a hydrogen and electron source such as water. It is believed that the pigments used for photosynthesis initially were used for protection from the harmful effects of light, particularly ultraviolet light. The process of photosynthesis was discovered by Jan Ingenhousz, a Dutch-born British physician and scientist, first publishing about it in 1779.
