Diatoms are an important group of aquatic ecosystems. To date, there have been many important algological studies in different river basins in Turkey. However, the use of diatoms in biomonitoring (according to diatom indices, Watanabe's or Van Dam's systems) is relatively new in Turkey. In the present study, 41 samples of epilithic diatoms were collected from 5 stations along Felent creek between June 2006 and February 2007 and a total of 117 diatom taxa were identified. The bio-indication (autoecology and abundance scores in the communities) of Felent creek was investigated and, as a result, the organic pollution indicators of Watanabe's …

Turkish Journal of Botany
Mycorrhizas play key roles in important ecosystem processes and functions. To enhance our understanding of the impact of mycorrhizal strategies on important foliar traits of host plants and their response to climate changes, we analysed 6 selected foliar traits among 54 plant species in 129 sampling sites of ascertained mycorrhizal types on the Tibetan Plateau based on their functional groups. The selected traits were leaf mass per area (LMA), nitrogen concentration (on mass and area bases, N_{mass} and N_{area}, respectively), photosynthetic capacity (A_{mass} and A_{area}) and photosynthetic nitrogen use efficiency (PNUE). The analysed foliar traits showed no significant difference between …

An Evaluation Of The Species Status Of Physaria Intermedia (Brassicaceae), Katie Arp
Honors Program Theses
The taxonomy of the genus Physaria (Brassicaceae) has been continually under revision as many species groups have proved difficult to resolve. Physaria intermedia (S. Watson) O'Kane Al-Shehbaz, has been a species whose circumscription has more recently been questioned and in need of clarification. The uncertainty surrounding the species stemmed from a combination of its geographical distribution, inhabiting two disjunct locations, as well as some minor differences in morphology that warranted a closer look. The species had been described as occupying southern Utah, northern and eastern (in northern 2/3) Arizona and southwest New Mexico with the remaining specimens inhabiting an isolated …

Efficacy Of A Novel Molecular Tool In Silencing Arabidopsis Genes, Chase Purnell, Vibha Srivastava, M. Aydin Akbudak, Scott J. Nicholson
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
RNA interference (RNAi), a pathway capable of silencing genes, has until recently only been achievable in the laboratory by the use of one method, expression of inverted repeat sequences of DNA. These constructs generate a double-stranded RNA, which in turn induce post-transcriptional silencing of other genes that bear sequence homology with the transgene. This approach of targeted gene silencing is extremely useful for studying the function of genes and engineering new traits in both plants and animals. It has recently been discovered that a transgene lacking the polyadenylation signal, called a truncated transgene, is also capable of inducing RNAi in …
