PLSCI 1130Light and Life: The Relationship between Light and Life in the Natural World3
By most accounts, whether theological or scientific, light is fundamental for life. Throughout the living world, there are vital processes, such as photosynthesis and vision that are associated with light. Living organisms use the daily and seasonal changes in illumination to regulate their rhythms. However, too much of a good thing is not necessarily a good thing as too much light can result in photodamage. The extraordinary relationship between light and life provides an important unifying framework for understanding the luminescence of living organisms, the striking and flamboyant coloration of plants and animals as well as the inconspicuous nature of their camouflage in terms of physics, chemistry and biology. This course will enhance your understanding of the natural world through studying the relationships between light and life. This course is suitable for life sciences majors.
Plant-based evidence has been an important component in solving crimes for centuries. Modern techniques and facilities have made plant evidence more important and useful than ever, and there are some stunning examples of trials where plant evidence played a critical roles in the outcomes. We will blend criminal cases and plant science in this course. We will review important cases that have involved and even depended upon significant plant-based evidence. Along the way, students will learn, at the introductory level, the plant science needed to appreciate the importance of plant-based evidence in crime solving. An overriding but intrinsic theme will be how the scientific method is useful and integral to applying logic to a body of plant-based evidence in specific cases. This course is suitable for life sciences majors.

PLSCI 1560Application of CHEM 1560 to Plant Sciences2
The purpose of this course is to facilitate making connections between biology and chemistry at the time you are learning the chemistry. In reality, chemistry is essential to biology. Life is, after all, a specialized set of chemical reactions, highly diverse and complex to be sure, but chemical reactions nonetheless. Developing an understanding and appreciation of this critical connection between chemistry and plant science is the primary goal of this course. At the same time, we should all recognize that chemistry is a challenging subject for most students. Because the application of chemistry to concepts and problems in biology first requires one to understand the chemistry, the course will also place a significant emphasis on making sure students understand the basic chemistry as well.

This course introduces the concept of plant-microbe interactions from mutualism to pathogens. The course explores how plants and microbes have co-evolved over time and the impact of climate change on plant-microbe interactions. Students should take this course if they are interested in microbial ecology and in preparation for upper-level plant pathology, virology, mycology, and plant-microbe interactions courses.
Plants have always played a key role in the history of life on Earth and have served as medicinal agents in all societies since prehistoric times. Medical Ethnobotany is the study of medicinal plants used by a group of people. Medicinal plants are either critical constituents of many modern drugs or provide templates for synthetic analogous molecules. In this course we will introduce and be acquainted with past and current plant-based natural remedies used across the globe, exploring their efficacy and mode of actions.

Crop ecology is the integrative study of biological, physical, social, and technological factors that govern the emergent properties arising from cropping systems at different spatial and temporal scales. It implicitly recognizes that achieving the goals for multi-functional (i.e. 'sustainable') agriculture cannot be achieved without understanding the functional interdependencies among these factors. This course serves as a graduate-level synthesis of 1) how crop and crop communities are influenced by the physical and chemical growth environment, 2) how the growth environment is modified by agronomy and, in turn, 3) how production processes are shaped by both managed and unmanaged factors. Readings and class discussions of key concepts compose the first half of the course, with the hands-on application of systems analysis tools emphasized in the second half.
Plant propagation, the multiplication of plants, is both a science and an art. This class will introduce the principles, practices and techniques of sexual and asexual propagation of horticultural plants.

The art of plant propagation will be learned through hands-on experiences with seed propagation, cutting propagation, grafting & budding systems, layering, specialized plant structures (bulbs, corms, etc.), and tissue culture for micropropagation. In addition, propagation media, greenhouse environmental control and management, and plant care, as they relate to propagation, will be emphasized. The science behind the methods that are learned will be explained in order to develop a better understanding of plant propagation and how to make it successful. This knowledge base and the practical, hands-on experiences will give students the ability to better solve problems that arise during the propagation and growth of plants.

PLSCI 6070Nutritional Quality Improvement of Food Crops2
The nutrients in human diets are ultimately derived from plants. However, the edible portions of the world's most extensively grown staple food crops are poor sources for numerous micronutrients and health-promoting compounds that are essential for sustaining and enhancing life. The improvement of crop nutritional quality through breeding, termed biofortification, is a sustainable strategy being used to address micronutrient deficiences worldwide. This course covers recent progress on crop nutritional quality trait improvement. The lectures will focus on vitamins, minerals, prebiotics, phytonutrients, essential amino acids, and fatty acids in the context of better human nutrition and health.

PLSCI 6100Plant Responses to Environmental Stresses and Global Climate Change3
Abiotic stresses including drought, temperature extremes, flooding, salinity, and toxic metals limit crop productivity, particularly in developing countries where people are resource-poor and have limited options. Anticipated global climate changes are expected to exacerbate the impact of stresses even further. Therefore, knowledge of stress response mechanisms is urgently needed for developing novel molecular breeding and genomics approaches for generating plants and management systems that will improve performance in hostile environmental conditions. This course explores the molecular, physiological, developmental and morphological characteristics that plants use to adapt to environmental stresses. Emphases are placed on stresses associated with global climate change including drought, flooding, extreme temperatures, salt, and environmental pollution. The course will also discuss strategies for improving stress tolerance in crops. Graduate students will have assignments for in-depth learning of each topic. Examination questions will differ for graduate students to evaluate assigned material. Graduate students will write a paper for one of the topics and present it in class.

PLSCI 6420Mineral Nutrition: From Plants to Humans3
Plants provide almost all essential minerals for humans and therefore plants are critical components of the human diet. Plant biologists address challenges of meeting the nutritional needs of the increasing world's population by studying plants' ability to uptake, translocate and accumulate mineral nutrients in edible tissues. By integrating basic plant biology with molecular breeding and genomics approaches, fundamental discoveries are utilized to have the greatest impact on solving biofortification of plant-based foods. This team-taught course explores the mechanisms of acquisition of mineral nutrients from the soil, translocation and accumulation in plant tissues, strategies to prevent mineral element deficiencies while avoiding their overload, and toxicity of noxious metals. Selected lectures focus on the relation between the nutrient status of plants and human nutrition and health. Graduate students will have assignments for in-depth learning of each topic. Examination questions will differ for graduate students to evaluate assigned material. Graduate students will write a paper for one of the topics and present it in class.
