Seed Micromorphological Survey Of The Minuartia Species (Caryophyllaceae) In Iran, Golaleh Mostafavi, Mostafa Assadi, Taher Nejadsattari, Fariba Sharifnia, Iraj Mehregan

Turkish Journal of Botany

Seed micromorphology of 20 species of Minuartia L. (Caryophyllaceae) that represent 2 different subgenera (i.e. Minuartia subgen. Spergella (Fenzl) McNeill and Minuartia subgen. Minuartia) were examined using scanning electron microscopy. Some qualitative and quantitative characters such as seed length and width, seed shape, cell shape, and cell ornamentations were studied. The results showed that seed micromorphology might provide useful tools in recognition and separation of Minuartia hamata (Hausskn.) Mattf. from other species of sect. Minuartia. Minuartia khorassanica Assadi & Mostafavi, a recently described species from Iran, is another species that micromorphologically was quite different. The species M. juniperina (L.) Maire …

Temperature And Functional Traits Influence Differences In Nitrogen Uptake Capacity Between Native And Invasive Grasses, A. Joshua Leffler, Jeremy J. James, Thomas A. Monaco

Natural Resource Management Faculty Publications

Performance differences between native and exotic invasive plants are often considered static, but invasive grasses may achieve growth advantages in western North America shrublands and steppe under only optimal growing conditions. We examine differences in N uptake and several morphological variables that influence uptake at temperatures between 5 and 25 C. We contrast two native perennial grasses in western North America: Elymus elymoides and Pseudoroegneria spicata; two invasive annual grasses: Bromus tectorum and Taeniatherum caputmedusae; and one highly selected non-native perennial grass: Agropyron cristatum. The influence of temperature on N uptake is poorly characterized, yet these invasive annual grasses are …

Opportunistic Pathogenic Bacteria Colonize Thorns Of Native Rio Grande Valley Plants, Felicia A. Charles, Sergio Cepeda, J. Andrew Mcdonald, Kristine L. Lowe

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Thorns serve as mechanical defenses of plants against herbivory. However, plant thorns harbor microorganisms that are potentially pathogenic. These pathogens may be transferred to herbivores and other animals and provide an additional defense for the plants. Thorns from 5 plant species native to the Rio Grande Valley of South Texas were collected and used to isolate bacteria colonizing the thorn surface. Thorns, leaves and stems of plants were visualized using Scanning Electron Microscopy (SEM) to observe any bacteria on the plant surface. Isolated bacteria were tested for their ability to grow in aerobic versus anaerobic environments, to produce hemolysis, carbon …

Turkish Journal of Botany

Morphological revision and phylogenetic analysis of Stachys L. sect. Eriostomum (Hoffmanns. & Link) Dumort. (Lamiaceae) based on nuclear ribosomal internal transcribed spacer (nrITS) sequences were conducted. Morphological analysis confirmed the previous arrangements of 3 subsections, i.e. Germanicae R.Bhattacharjee, Creticae R.Bhattacharjee, and Spectabiles R.Bhattacharjee, while suggesting some status changes and new records that were also confirmed by the phylogenetic analysis. The phylogenetic analysis suggested, however, some arrangements different from those indicated by morphology. Two subsections, i.e. Creticae and Germanicae-Spectabiles, instead of 3 were observed in the phylogenetic tree. The tree also suggested that 9 Stachys cretica L. subspecies form a polyphyletic …
