When Island-Like Populations At High Elevation Show Genetic Divergence Despite No Morphological Variability: The Case Of Lupinus Montanus In Central Mexico, Maxime Ferval, Luc Legal, Charles Gers, Céline Pélissier, Peter Winterton, Jesús Arnoldo Sánchez López, María Luisa Corona Rangel, Kalina Bermudez Torres

Turkish Journal of Botany

Lupinus montanus subsp. montanus var. montanus Kunth is a widespread taxon occurring throughout the highlands of Central Mexico and Guatemala. Populations of this variety show little variation in plant morphology, but their highly disjunct island-like distribution suggests that genetic differentiation between populations should be expected. To test this idea, we assessed genetic diversity among 13 populations of Lupinus montanus var. montanus growing on the 6 main volcanoes of the Trans-Mexican Volcanic Belt (TMVB) using 4 intersimple sequence repeat markers to quantify genetic divergence. The 93 loci identified showed significant differentiation between populations (F_{ST} \approx 0.5) and high levels of genetic …

Comparative Anatomy Of Elaiophores And Oil Secretion In The Genus Gomesa (Orchidaceae), Natalia Elva Gomiz, Juan Pablo Torretta, Sandra Silvina Aliscioni

Turkish Journal of Botany

Oils are atypical floral rewards in Orchidaceae and are produced by epidermal glands called elaiophores. Flowers of many members of the subtribe Oncidiinae either produce oil or mimic oil-producing flowers of Malpighiaceae. We focus our research on 3 species of Gomesa, namely, G. flexuosa, G. riograndensis, and G. varicosa in order to investigate the presence of elaiophores, their micromorphology and internal structure, and the process of oil secretion. Elaiophores were located using Sudan III and their internal and external features examined using light and scanning electron microscopy, respectively. The presence of elaiophores was confirmed for regions of calli that are …

Cadmium Detoxification In Populus × Canescens, Huiping Dai, Chanjuan Shan, Gengliang Jia, Chao Lu, Tuxi Yang, Anzhi Wei

Turkish Journal of Botany

Cadmium is one of the most toxic heavy metals and affects all viable cells, even at low concentrations. It is introduced to agricultural soils mainly by phosphate fertilisers and causes many toxic symptoms in cells. Phytochelatins (PCs) are heavy metal-binding peptides that play an important role in sequestration and detoxification of heavy metals in plants. In this study, after a 12-week cultivation, the plants were treated with 5 CdSO4•7 H_{2}O concentrations of 0 (control), 10, 30, 50, and 70 µM for 28 days. The effects of Cd on growth and on glutathione (GSH) and PC contents were investigated in the …

Factors Influencing The Establishment And Survival Of Native Hardwood Tree Seedlings Of The Kentucky Inner Bluegrass Blue Ash-Oak Savanna-Woodland, James D. Shaffer 2013 University of Kentucky

Factors Influencing The Establishment And Survival Of Native Hardwood Tree Seedlings Of The Kentucky Inner Bluegrass Blue Ash-Oak Savanna-Woodland, James D. Shaffer

Theses and Dissertations--Biology

Historically, the Kentucky Inner Bluegrass blue ash-oak savanna-woodland was the primary ecosystem of the Inner Bluegrass Region (IBR) of Kentucky. After European settlement, the majority (>99%) of Bluegrass savanna was converted to agricultural and urban land uses. Currently remnant savanna tree species are failing to recruit. Therefore, a long-term restoration ecology project researching competition and disturbance on seedling establishment, survival, and growth has been established at Griffith Woods (the largest remaining savanna in Kentucky) in Harrison Co., KY. Fourteen native hardwood tree species (a total of 6,168 seedlings) have been experimentally planted. Light, soil, surrounding vegetation, and herbivory, factors …
