Joy Michele Bergelson is an American evolutionary biologist. She is currently the Dorothy Schiff Professor of Genomics at New York University. [1] Bergelson was previously and James D. Watson Distinguished Service Professor of Ecology and Evolution at the University of Chicago, where she chaired the department for ecology and evolution. Her research focuses on the evolution and ecology of plants. [2]
Born in Brooklyn, New York and raised in Metuchen, New Jersey, [3] She graduated in 1980 from Metuchen High School, which inducted her into its hall of fame in 2017. [4]
Bergelson graduated from Brown University with an ScB in Biology in 1984. She went on to further study as a Marshall Scholar at the University of York, receiving an MPhil in Biology in 1986 and a PhD in zoology from the University of Washington in 1990. [2] Bergelson worked as a demonstrator in Ecology at the University of Oxford, before joining the faculty of the Washington University in St. Louis in 1992. She left St. Louis for Chicago in 1994. [5]
She served as the section chair for Biology of the American Association for the Advancement of Science in 2012. [6]
Bergelson is known for her research on the model plant species Arabidopsis thaliana , its ecology and the evolution of plant-pathogen interactions. Her early research examined interactions between insects and trees, [7] spatial patterns in trees [8] and weeds, [9] and the energetic cost to plants to resist insects. [10] Subsequently, she examined genetic variation in Arabidopsis thaliana, [11] [12] the genetic basis for disease resistance in plants, [13] and polymorphisms in Arabidopsis. [14] [15] Bergelson's research has also examined genetic adaptations in plants to recent climate change. [16]
An annual plant is a plant that completes its life cycle, from germination to the production of seeds, within one growing season, and then dies. Globally, only 6% of all plant species and 15% of herbaceous plants are annuals. The annual life cycle has independently emerged in over 120 different plant families throughout the entire angiosperm phylogeny.
Arabidopsis (rockcress) is a genus in the family Brassicaceae. They are small flowering plants related to cabbage and mustard. This genus is of great interest since it contains thale cress, one of the model organisms used for studying plant biology and the first plant to have its entire genome sequenced. Changes in thale cress are easily observed, making it a very useful model.
Arabidopsis thaliana, the thale cress, mouse-ear cress or arabidopsis, is a small plant from the mustard family (Brassicaceae), native to Eurasia and Africa. Commonly found along the shoulders of roads and in disturbed land, it is generally considered a weed.
Self-pollination is a form of pollination in which pollen from the same plant arrives at the stigma of a flower or at the ovule. There are two types of self-pollination: in autogamy, pollen is transferred to the stigma of the same flower; in geitonogamy, pollen is transferred from the anther of one flower to the stigma of another flower on the same flowering plant, or from microsporangium to ovule within a single (monoecious) gymnosperm. Some plants have mechanisms that ensure autogamy, such as flowers that do not open (cleistogamy), or stamens that move to come into contact with the stigma. The term selfing that is often used as a synonym, is not limited to self-pollination, but also applies to other type of self-fertilization.
Deborah Charlesworth is a population geneticist from the UK, notable for her important discoveries in population genetics and evolutionary biology. Her most notable research is in understanding the evolution of recombination, sex chromosomes and mating system for plants.
A primordium in embryology, is an organ or tissue in its earliest recognizable stage of development. Cells of the primordium are called primordial cells. A primordium is the simplest set of cells capable of triggering growth of the would-be organ and the initial foundation from which an organ is able to grow. In flowering plants, a floral primordium gives rise to a flower.
The MADS box is a conserved sequence motif. The genes which contain this motif are called the MADS-box gene family. The MADS box encodes the DNA-binding MADS domain. The MADS domain binds to DNA sequences of high similarity to the motif CC[A/T]6GG termed the CArG-box. MADS-domain proteins are generally transcription factors. The length of the MADS-box reported by various researchers varies somewhat, but typical lengths are in the range of 168 to 180 base pairs, i.e. the encoded MADS domain has a length of 56 to 60 amino acids. There is evidence that the MADS domain evolved from a sequence stretch of a type II topoisomerase in a common ancestor of all extant eukaryotes.
Martin Edward Kreitman is an American geneticist at the University of Chicago, most well known for the McDonald–Kreitman test that is used to infer the amount of adaptive evolution in population genetic studies.
Detlef Weigel is a German American scientist working at the interface of developmental and evolutionary biology.
Joanne Chory is an American plant biologist and geneticist. Chory is a professor and director of the Plant Molecular and Cellular Biology Laboratory, at the Salk Institute for Biological Studies and an investigator of the Howard Hughes Medical Institute.
Johanna Schmitt is an evolutionary ecologist and plant geneticist. Her research is notable for its focus on the genetic basis of traits in ecologically valuable plants and on predicting how such plants will respond and adapt to environmental change such as climate warming. She has authored over 100 articles and her works have been cited over 7900 citations. She is honored with being the first female scientist at Brown University to be elected to the National Academy of Sciences.
Liam Dolan is a Senior Group Leader at the Gregor Mendel Institute of Molecular Plant Biology (GMI) of the Austrian Academy of Sciences, the Sherardian Professor of Botany in the Department of Biology at the University of Oxford and a Fellow of Magdalen College, Oxford.
Steven M. Smith is Emeritus Professor of Plant Genetics and Biochemistry at the University of Tasmania in Australia and Chief Investigator in the Australian Research Council Centre of Excellence for Plant Success in Nature and Agriculture.
Robert L. Last is a plant biochemical genomicist who studies metabolic processes that protect plants from the environment and produce products important for animal and human nutrition. His research has covered (1) production and breakdown of essential amino acids, (2) the synthesis and protective roles of Vitamin C and Vitamin E (tocopherols) as well as identification of mechanisms that protect photosystem II from damage, and (3) synthesis and biological functions of plant protective specialized metabolites. Four central questions are: (i) how are leaf and seed amino acids levels regulated, (ii.) what mechanisms protect and repair photosystem II from stress-induced damage, (iii.) how do plants produce protective metabolites in their glandular secreting trichomes (iv.) and what are the evolutionary mechanisms that contribute to the tremendous diversity of specialized metabolites that protect plants from insects and pathogens and are used as therapeutic agents.
Arabidopsis thaliana is a first class model organism and the single most important species for fundamental research in plant molecular genetics.
Sexual selection in Arabidopsis thaliana is a mode of natural selection by which the flowering plant Arabidopsis thaliana selects mates to maximize reproductive success.
Georg Jander is an American plant biologist at the Boyce Thompson Institute in Ithaca, New York. He has an adjunct appointment in the Plant Biology Section of the School of Integrative Plant Sciences at Cornell University. Jander is known for his molecular research identifying genes for biochemical compounds of ecological and agricultural importance, particularly those plant traits involved in resistance to insect pests.
June Nasrallah is Barbara McClintock Professor in the Plant Biology Section of the School of Integrative Plant Science at Cornell University. Her research focuses on plant reproductive biology and the cell-cell interactions that underlie self-incompatibility in plants belonging to the mustard (Brassicaceae) family. She was elected to the US National Academy of Sciences in 2003 for this work and her contributions generally to our understanding of receptor-based signaling in plants.
