Auxin Regulation Of Arabidopsis Flower Development Involves Members Of The Aintegumenta-Like/Plethora (Ail/Plt) Family, Beth A. Krizek
Faculty Publications
Auxin is an important regulator of many aspects of plant growth and development. During reproductive development, auxin specifies the site of flower initiation and subsequently regulates organ growth and patterning as well as later events that determine reproductive success. Underlying auxin action in plant tissues is its uneven distribution, resulting in groups of cells with high auxin levels (auxin maxima) or graded distributions of the hormone (auxin gradients). Dynamic auxin distribution within the periphery of the inflorescence meristems specifies the site of floral meristem initiation, while auxin maxima present at the tips of developing floral organ primordia probably mediate organ …

Deer Browse Monitoring Of The Lupine Population At John Merle Coulter Prairie And The Trillium Population At Hildebrand Lake, Jana C. Cram, Heather Dulaney
Symposium on Research and Creative Expression (SORCE)
A facet of ecological restoration practices in northwest Indiana involves monitoring and supporting the growth of various plants native to the region, including wild lupine (Lupinus perennis) and large-flowering trillium (Trillium grandiflorum). White-tailed deer are a common threat to these species because they eat, or browse, the flowers from these plants. This project investigated the amount of wild lupine and large-flowering trillium browsed by white-tailed deer at Coulter Prairie and Hildebrand Lake, respectively, over a four-year period. Plant counts are taken from permanent transect lines of 30 and 50 meters in length and measured in one …

Improving Ecological Monitoring Of Restoration Sites In Northwest Indiana Through A Glisten-Nirmi Partnership., Danyi Harper, Don Meola
Symposium on Research and Creative Expression (SORCE)
Northwest Indiana is an area of active ecological restoration with 169 documented restoration projects. However, the ability to assess the success of restoration projects is incomplete because monitoring of the progress of these restorations does not exist. NIRMI was created in 2010 to establish a system of evaluating and quantifying plant species in local habitat restoration projects throughout Northwest Indiana. NIRMI uses a standardized approach to collect data that is placed within an open-access database for use by other researchers, restoration groups, and individuals in evaluation of restoration efforts. Data collection uses the CVS-EEP protocol for recording vegetation, a standard …

Fruit And Seed Morphology Of The Fumaria L. Species (Papaveraceae) Of Iran, Fatemeh Ebrahimzadeh Araii, Maryam Keshavarzi, Masoud Sheidaii, Parinaz Ghadam
Turkish Journal of Botany
The macro and micro fruit and seed morphology and surface ornamentations of 21 populations of 6 Fumaria L. species were investigated using stereomicroscope and scanning electron microscopy. These data are shown to support data from the general morphology. The results indicate that the fruit and seed characters of the genus Fumaria are valuable for taxonomic applications and are useful for classification. F. officinalis show a different shape in their fruit. The close relationships are observed for F. parviflora and F. vaillantii. F. indica, as a hybrid between F. asepala and F. parviflora, shows intermediate micro-morphological features.

Ocimum basilicum L. seedlings were exposed to different concentrations of Cr (0-8 mg L^{-1} of Cr^{3+}) to evaluate the cellular localisation of chromium, plant accumulating capacity, and potential cellular defence mechanisms against Cr stress. Dried plant tissues (roots and shoots) were exposed to X-ray microanalysis for element determination (including Cr, Cu, Zn, Co, Ni, and Mo). Results showed that the highest amount of Cr had accumulated in the roots of the plants treated with 8 mg L^{-1} of Cr^{3+}, while less Cr was transported to the shoots. TEM micrographs of Ocimum basilicum root cortex cells exposed to 4, 6, and …

Strategies For Conserving Forest Genetic Resources In The Face Of Climate Change, John Bradley St.Clair, Glenn Thomas Howe
Turkish Journal of Botany
Conservation of genetic diversity is important for continued evolution of populations to new environments, as well as continued availability of traits of interest in genetic improvement programs. Rapidly changing climates present new threats to the conservation of forest genetic resources. We can no longer assume that in situ reserves will continue to preserve existing genetic diversity. Management of reserves should become more active. In some reserves, existing genetic diversity should be preserved by creating stands that are more resistant to threats using silvicultural treatments such as thinning and prescribed burning. In other reserves, natural selection and adaptation to changed environments …

Seed Morphology And Anatomy Of The Mediterranean Pentamerous Species Of Erica (Ericaceae), Jaime Fagundez, Jesus Izco
Turkish Journal of Botany
The species of the "Pentapera group" are distinguished from the rest of the European and Mediterranean Erica L. species by having 5 corolla lobes and sepals instead of 4, and 10 stamens instead of 8. The genus Pentapera Klotzsch was proposed for these taxa but recent studies regards it as part of Erica. Two species are recognised: Erica sicula Guss. and E. bocquetii (Peşmen) P.F.Stevens, and 3 subspecies have been described within E. sicula. This taxonomic treatment is still under discussion and relationships with other species have been poorly discussed. Seed morphology of the 2 species and the 3 subspecies …
