Popped Secret: the Mysterious Origin of Corn Film Guide Educator Materials
Popped Secret: The Mysterious Origin of Corn Film Guide Educator Materials OVERVIEW In the HHMI film Popped Secret: The Mysterious Origin of Corn, evolutionary biologist Dr. Neil Losin embarks on a quest to discover the origin of maize (or corn). While the wild varieties of common crops, such as apples and wheat, looked much like the cultivated species, there are no wild plants that closely resemble maize. As the film unfolds, we learn how geneticists and archaeologists have come together to unravel the mysteries of how and where maize was domesticated nearly 9,000 years ago. KEY CONCEPTS A. Humans have transformed wild plants into useful crops by artificially selecting and propagating individuals with the most desirable traits or characteristics—such as size, color, or sweetness—over generations. B. Evidence of early maize domestication comes from many disciplines including evolutionary biology, genetics, and archaeology. C. The analysis of shared characteristics among different species, including extinct ones, enables scientists to determine evolutionary relationships. D. In general, the more closely related two groups of organisms are, the more similar their DNA sequences will be. Scientists can estimate how long ago two populations of organisms diverged by comparing their genomes. E. When the number of genes is relatively small, mathematical models based on Mendelian genetics can help scientists estimate how many genes are involved in the differences in traits between species. F. Regulatory genes code for proteins, such as transcription factors, that in turn control the expression of several—even hundreds—of other genes. As a result, changes in just a few regulatory genes can have a dramatic effect on traits. -

Who Doesn't Love Fresh Corn on the Cob in the Summer?
Corn Ahh - who doesn’t love fresh corn on the cob in the summer? It is so good, and so good for you! It not only provides the necessary calories for daily metabolism, but is a rich source of vitamins A, B, E and many minerals. Its high fiber content ensures that it plays a role in prevention of digestive ailments. Growing info: We're expanding our sweet corn production this year by popular demand. The issue with corn, is it takes a lot of space. You can get about 100 ears from every 100 row-feet of planting. When a share consists of 8 ears of corn, this is 8 feet for one share! We plant corn in succession starting in mid May. This will give us a constant supply through summer. Common Problems: Corn ear worms are the TIPS: major pest we deal with in corn. They are tiny little worms that crawl into the tip of the ear and Short-term Storage: Corn converts it's start eating. By the time they get an inch down sugars into starch soon after peak the tip of the ear, they will have grown to a large ripeness, so best to eat it soon. and ugly size.

Zimmerer 1 ABSTRACT. I examined agrobiodiversity in smallholder cultural landscapes with the goal of offering new insights into management and policy options for the resilience-based in situ conservation and social-ecological sustainability of local, food-producing crop types, i.e., landraces. I built a general, integrative approach to focus on both land use and livelihood functions of crop landraces in the context of nontraditional, migration-related livelihoods amid global change. The research involved a multimethod, case-study design focused on a cultural landscape of maize, i.e., corn, growing in the Andes of central Bolivia, which is a global hot spot for this crop’s agrobiodiversity. Central questions included the following: (1) What are major agroecological functions and food-related services of the agrobiodiversity of Andean maize landraces, and how are they related to cultural landscapes and associated knowledge systems? (2) What are new migration-related livelihood groups, and how are their dynamic livelihoods propelled through global change, in particular international and national migration, linked to the use and cultural landscapes of agrobiodiversity? (3) What are management and policy options derived from the previous questions? Combined social-ecological services as both cultivation and food resources are found to function in relation to the cultural landscape. -

Hugh H. Iltis Doctor Honoris Causa 2 El maíz ha sido una de las grandes contribuciones de México al mundo y el Dr. Hugh Iltis es uno de los científicos que con mayor tenacidad ha dedicado su vida a desentrañar los misterios evolutivos del segundo grano de mayor importancia en el planeta. La Universidad de Guadalajara brinda un reconocimiento al trabajo del Dr. Iltis, colaborador nuestro durante tres décadas ininterrumpidas, cuyas aportaciones no sólo representan avances ante los desafíos intelectuales de la investigación básica, sino también en la formación de recursos humanos, y en la aplicación práctica del conocimiento para la conservación de los recursos naturales y alimentarios de un mundo en franco deterioro. Historia personal Hugh H. Iltis nació el 7 de abril de 1925 en Brno, Checoslovaquia. Su padre, el destacado naturista Hugo Iltis, fue profesor de Biología, Botánica y Genética en Brünn Checoslovaquia y profesor de Biología en la Universidad de Virginia. Siendo niño tuvo que migrar a los Estados Unidos de Norteamérica como refugiado cuando su país fue invadido por los nazis. Estimulado por su padre, se interesó en la genética y la botánica, muy pronto se entusiasmó por la Taxonomía y la Evolución de las plantas. Su carrera como botánico inició a muy temprana edad, pues a los 14 años ya había construido su propio herbario, y los ejemplares contaban con sus nombres en latín y descripciones. Estos ejemplares tuvieron que ser vendidos para ayudarse en sus estudios en la Universidad de Tennessee. Al año de haber iniciado en la universidad, tuvo que incorporarse al ejército de los Estados Unidos durante la Segunda Guerra Mundial, donde participó como analista de información 3 Hugh H. -

Archaeologically Defining the Earlier Garden Landscapes at Morven: Preliminary Results Abstract The first phase of archaeology at Morven was designed to test the potential for further study of the early garden landscape at a ca. 1758 house in Princeton, New jersey. The research included intensive botanical analysis using a variety of archaeobotanical techniques integrated within a broader ethnobotanical framework. A study was also made of the garden's topography using map analysis combined with subsurface testing. Information on garden features related to the design of earlier garden surfaces
