Turkish Journal of Botany

Peganum harmala is a halonitrophilous perennial herb that is relevant in the landscape of steppe, semidesert, and desert territories in southern Europe, northern Africa, and southwestern Asia. We present here data on the nuclear DNA amount assessment in one Iberian and 17 Tunisian populations of this species. The 2C values, belonging to the very small genome category, ranged from 0.61 to 0.67 pg. These data are the first on genome size for the species and for the whole genus and the whole family. In addition, the somatic chromosome number (2n = 24) has been counted in one population, confirming previous …

Phlomis Iranica (Lamiaceae: Lamioideae), A New Species Fromthe Khorassan-Kopet Dagh Floristic Province, Ne Iran, Jamil Vaezi, Maryam Behroozian, Mohammad Reza Joharchi, Farshid Memariani

Micro-Spectroscopy Of Bio-Assemblies At The Single Cell Level, Jeslin Kera

Honors Undergraduate Theses

In this thesis, we investigate biological molecules on a micron scale in the ultraviolet spectral region through the non-destructive confocal absorption microscopy. The setup involves a combination of confocal microscope with a UV light excitation beam to measure the optical absorption spectra with spatial resolution of 1.4 μm in the lateral and 3.6 μm in the axial direction. Confocal absorption microscopy has the benefits of requiring no labels and only low light intensity for excitation while providing a strong signal from the contrast generated by the attenuation of propagating light due to absorption. This enables spatially resolved measurements of single …

Taxonomic Position Of Abies Equi-Trojani On The Basis Of Needlecharacters By Comparison With Different Fir Species, Anna Katarzyna Jasinska, Katarzyna Sekiewicz, Tolga Ok, Angel Romo, Adam Boratynski, Krystyna Boratynska

Turkish Journal of Botany

The needles from 25 trees of Abies equi-trojani from Kazdağı (Mount Ida) were compared with those from four populations of A. alba, two of A. cephalonica, and three of each of A. xborisii-regis, A. bornmuelleriana, and A. nordmanniana, each represented by 29-31 individuals. Thirty-nine morphological and anatomical needle characters (26 main and 13 estimated ones) were examined biometrically to verify the systematic position of A. equi-trojani. To evaluate the relationships among taxa, Student's t-test for independent samples, the Mann-Whitney U test, and discrimination and clustering analyses were applied. The differences between taxa were statistically significant for several characters, but the …

Seed Dispersal For The Unusual Inflated Berries Of Burmeistera (Campanulaceae), Diana Gamba, N. Maguiña, Camilo Calderón-Acevedo, Karina Torres, Nathan Muchhala

Biology Department Faculty Works

Examining dispersal is critical for understanding the diversity of Andean-centered plant lineages, like Burmeistera (Campanulaceae). One-third of its species present an unusual inflated berry. Unlike the bright colors of non-inflated fruits in the genus, these fruits are typically dull-green; however, the fact that the seeds are loosely held in the placenta and easily removed when touched seems to suggest adaptation to animal dispersal. We studied two inflated-baccate species, Burmeistera glabrata and B. borjensis, with the aim of testing the non-exclusive hypotheses that their seeds are dispersed by (1) small mammals, (2) slugs, or (3) adult flies that develop inside the …

Sexual Dimorphism In The Moss Bryum Argenteum And Its Implications For Sex Ratio Bias, Jonathan David Moore Iii

Theses and Dissertations--Biology

In dioecious plants, selection due to sex function differences has produced sex-specific life histories, morphologies, and physiologies. In many dioecious seed plants, dimorphisms and population sex ratios have been plausibly linked, but similar links are not yet apparent in dioecious bryophytes. Population sex ratio bias is often expected to favor the sex with lower investment in sexual reproduction, especially in resource-poor environments. Unlike in seed plants, bryophyte males may have higher average reproductive investment than females, which typically have low offspring production rates due to sperm limitation. However, traits aside from reproductive investment such as shoot and leaf arrangement may …

Local Wind Monitoring Matched With Lichen Pseudevernia Furfuracea (L.) Zopf Transplantation Technique To Assess The Environmental Impact Of A Biomass Power Plant, Lucio Lucadamo, Anna Corapi, Luana Gallo

Turkish Journal of Botany

The potential environmental impact of a biomass power plant (BPP) was evaluated by transplanting thalli of the lichen Pseudevernia furfuracea (L.) Zopf in the surrounding area for 3 months. Four meteorological stations were placed at four sites to monitor local winds. At the end of the period, thalli were retrieved and electrical conductivity percentage (EC%), lipid peroxidation, lichen vitality, photosynthetic efficiency, chlorophylls, xanthophylls+carotenoids, OD435/OD415, and concentrations of some elements frequently emitted by BPPs were measured. A univariate-multivariate analysis revealed clusters of sites with dissimilar mean values of ecophysiological parameters. They were merged, when not significantly differing, and classified as different …

Characterization Of The Beta1 Gene, Which Might Play A Role In Beta Vulgaris Subsp. Maritima Salt Tolerance, Özge Uysal, Çi̇ğdem Çakiroğlu, Ahmet Koç, Hüseyi̇n Çağlar Karakaya

Turkish Journal of Botany

Salinity stress has a negative impact on plant growth, which affects homeostasis and productivity. The uptake of nonessential salt ions changes the osmotic balance of the cell and causes dehydration. Higher plants develop salt tolerance mechanisms to avoid dehydration. Sea beet (Beta vulgaris subsp. maritima) is a halophytic ancestor of cultivated sugar beet that displays salt stress tolerance. In this study, we screened a B. vulgaris subsp. maritima cDNA library in Saccharomyces cerevisiae strain Ab11c (ena1Δ, nha1/4Δ, nhx1Δ), which is deficient in sodium transport, to find sodium-detoxifying genes. We identified a cDNA construct, named BETA1, providing salt tolerance to yeast …

Remarkable productivity has been achieved in crop species through artificial selection and adaptation to modern agronomic practices. Whether intensive selection has changed the ability of improved cultivars to maintain high productivity across variable environments is unknown. Understanding the genetic control of phenotypic plasticity and genotype by environment (G × E) interaction will enhance crop performance predictions across diverse environments. Here we use data generated from the Genomes to Fields (G2F) Maize G × E project to assess the effect of selection on G × E variation and characterize polymorphisms associated with plasticity. Genomic regions putatively selected during modern temperate maize …

Allelic Variants Of Oshkt1;1 Underlie The Divergence Between Indica And Japonica Subspecies Of Rice (Oryza Sativa) For Root Sodium Content, Malachy T. Campbell, Nonoy Bandillo, Fouad Razzaq A. Al Shiblawi, Sandeep Sharma, Kan Liu, Qian Du, Aaron J. Schmitz, Chi Zhang, Anne-Alienor Very, Aaron J. Lorenz, Harkamal Walia

Department of Agronomy and Horticulture: Faculty Publications

Salinity is a major factor limiting crop productivity. Rice (Oryza sativa), a staple crop for the majority of the world, is highly sensitive to salinity stress. To discover novel sources of genetic variation for salt tolerance-related traits in rice, we screened 390 diverse accessions under 14 days of moderate (9 dS m^-1) salinity. In this study, shoot growth responses to moderate levels of salinity were independent of tissue Na⁺ content. A significant difference in root Na+ content was observed between the major subpopulations of rice, with indica accessions displaying higher root Na⁺ and japonica …

Jasmonoyl-L-Tryptophan Disrupts Iaa Activity Through The Aux1 Auxin Permease, Paul E. Staswick, Martha Rowe, Edgar P. Spalding, Bessie L. Splitt

Department of Agronomy and Horticulture: Faculty Publications

Amide-linked conjugates between tryptophan (Trp) and jasmonic (JA) or indole-3- acetic (IAA) acids interfered with gravitropism and other auxin-dependent activities in Arabidopsis, but the mechanism was unclear. To identify structural features necessary for activity several additional Trp conjugates were synthesized. The phenylacetic acid (PAA) conjugate was active, while several others were not. Common features of active conjugates is that they have ring structures that are linked to Trp through an acetic acid side chain, while longer or shorter linkages are inactive or less active. A dominant mutant, called tryptophan conjugate response1-D that is insensitive to JA-Trp, but still sensitive …
