Available in PDF, EPUB and Kindle. Book excerpt: The presence of polymorphic seed colors in plant species of the Fabaceae (legume) family has been attributed to several factors including genetics and the environment. These colors are determined primarily by the relative amounts of anthocyanin pigments present in the seed coat. Anthocyanins play significant roles in seed dispersal and tolerance to environmental stressors including ultraviolet (UV) radiation. UV-B radiation can be particularly damaging to plants and anthocyanins are thought to mitigate UV-B damage through absorption and antioxidant characteristics. Lupinus perennis is a perennial, herbaceous plant in which Ohio populations are polymorphic for seed color with seed coats ranging from completely white seed coats to varying amounts of brown/black speckling due to differences in coat biochemistry including anthocyanins. This study aimed to examine growth and leaf color characteristics of different seed color phenotypes in Lupinus perennis in response to UV stress. To determine the effects of seed color and UV on plant growth we grew seeds from two seed phenotypes, white (0-5% speckling) and dark (40-100% speckling) in a common environment with or without UV-B radiation. We hypothesized that seed coat phenotypes are likely to have differences in seedling biochemistry and therefore seedlings from dark seeds will have greater growth than those from white seeds when exposed to UV-B wavelengths. In addition, we used image analysis of digital photographs to examine differences in leaf tissue colors between seed phenotypes and UV treatments to determine differences in leaf pigment content without destructive harvests. We found that contrary to our predictions, white seeds produced larger plants with more leaves and greater total leaf surface areas than those plants grown from dark seeds. Furthermore, we found that plants grown under UV lights were also larger than those grown without UV. Finally, we found that leaf tissues of plants exposed to UV-B wavelengths were more yellow-green in color than those left unexposed. These results have important implications for endangered butterfly habitat restoration and crop breeding in the genus Lupinus and suggest that white seeds may be more desirable for restoration plantings and crop selection in domesticated lupin. Further work is warranted to examine possible differences in fitness and leaf tissue chemistry associated with seed color variation in L. perennis.

Book Synopsis IMPACTS OF A SEED PREDATOR ON SUNDIAL LUPINE by : Jennifer Shimola

Available in PDF, EPUB and Kindle. Book excerpt: Sundial lupine, Lupinus perennis (L.), is a perennial flowering legume integral to maintaining reproductive populations of the federally endangered Karner Blue butterfly. The seed coats of L. perennis are polymorphic, with variable amounts of dark speckling ranging from light to heavily speckled against a white to gray background. In this legume species, darker seeds may contain secondary metabolites like tannins and anthocyanins, which may be associated with deterring seed predation. Other studies have found lighter colored seeds to have weaker seed coats, be more digestible, and have higher nutritional value than darker seeds. The chemical and physical traits of lighter seed coats could make this seed type more desirable for seed predators as well as agriculturalists. The seeds of L. perennis are a known food source of ant-mimicking alydid insects, Megalotomus quinquespinosus and Alydus spp. This study explored whether alydids have a preference for seed coat color variants of L. perennis and simultaneously determined the relative abundance of this seed predator and the frequency of L. perennis seed colors in field surveys of ten populations. We expected to find that 1) alydids would be found at greater frequencies when lighter seeds were present and 2) the most amount of time during a seed choice experiment will be spent interacting with lighter seeds. We also measured environmental characteristics to determine whether other factors may be playing a role in the distribution of L. perennis seed color or alydids. We expected soil characteristics to camouflage seeds, canopy cover and litter depth would influence site productivity, and that greater food availability would increase alydid abundance. Populations of L. perennis were surveyed for seed color frequencies, alydid frequencies, environmental variables, and the presence of other legume species. Sites were confirmed to differ in the amount of speckling and proportion of seeds with speckling present. Seed speckling was impacted by soil characteristics, canopy cover, and pod abundance. Alydid abundance was impacted by food availability (pod abundance and the presence of other legumes), soil characteristics, and the amount of speckling. Fewer alydids were found in populations with darker speckled seeds. A multiple choice behavioral experiment was performed on adult M. quinquespinosus to clarify findings of the population survey. There was no significant difference in alydid behavior with different seed colors, though we observed a trend of greater time interacting, a greater proportion of time, and more frequent visits to darker seeds. Based on the findings of our population survey and behavioral experiment, alydids did not have a strong preference for lighter seed colors in L. perennis. Some explanations for the differences in seed color abundance among sites are that seed color is random or undergoing selective pressures that we did not consider such as post-dispersal seed predators, the attraction of beneficial microbes, maintaining non-synchronous germination, or pleiotropic effects. Understanding whether this seed color polymorphism is important to L. perennis fitness may be important in future management decisions and should be further studied.

Book Synopsis Seedling Ecology and Evolution by : Mary Allessio Leck
Download or read book Seedling Ecology and Evolution written by Mary Allessio Leck and published by Cambridge University Press. This book was released on 2008-09-18 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seedlings are highly sensitive to their environment. After seeds, they typically suffer the highest mortality of any life history stage. This book provides a comprehensive exploration of the seedling stage of the plant life cycle. It considers the importance of seedlings in plant communities; environmental factors with special impact on seedlings; the morphological and physiological diversity of seedlings including mycorrhizae; the relationship of the seedling with other life stages; seedling evolution; and seedlings in human altered ecosystems, including deserts, tropical rainforests, and habitat restoration projects. The diversity of seedlings is portrayed by including specialised groups like orchids, bromeliads, and parasitic and carnivorous plants. Discussions of physiology, morphology, evolution and ecology are brought together to focus on how and why seedlings are successful. This important text sets the stage for future research and is valuable to graduate students and researchers in plant ecology, botany, agriculture and conservation.
