A Comparative Study Of Carnivorous Leaves In The Genus Sarracenia, Katie Nolan
A Comparative Study Of Carnivorous Leaves In The Genus Sarracenia, Katie Nolan
Master's Theses and Doctoral Dissertations
The carnivorous pitcher plant genus, Sarracenia, has modified leaves adapted to lure, trap, and digest insect prey. Little is known about surface microstructural ornamentation and variation throughout the genus. Four zones of the leaf were examined in four species throughout the range of the genus using scanning electron microscopy (SEM). Nine unique microstructures were identified in the carnivorous leaf. For the first time, microstructures (N=880) were systematically measured and zonal averages were compared among zones (with MANOVA) and species (with PCA). Microstructures are significantly different among zones of the same leaf and vary among different species. These data suggest …
Characterization Of Winter Microbial Communities In The Purple Pitcher Plant (Sarracenia Purpurea), Reid Jeffrey Tornquist
Characterization Of Winter Microbial Communities In The Purple Pitcher Plant (Sarracenia Purpurea), Reid Jeffrey Tornquist
Master's Theses and Doctoral Dissertations
Carnivorous pitcher plants trap insects in cone-shaped leaves and digest them to gain vital nutrients. For digestion to occur, plants in the genus Sarracenia require mutualistic microorganisms living in their leaves. Few studies have examined how these communities change over time. This study specifically examines the bacterial composition in the most widely distributed species, Sarracenia purpurea, in the winter. The leaves of this plant species live for several years, and it is unknown whether microbes overwinter in pitcher fluid or if community structure must be reestablished each spring. This study aims to characterize the winter microbiome in two population …
