Effects Of Exogenous Methyl Jasmonate And 2-Isopentenyladenine On Artemisinin Production And Gene Expression In Artemisia Annua, Mahboobeh Zare Mehrjerdi, Mohammad Reza Bihamta, Mansoor Omidi, Mohammad Reza Naghavi, Hassan Soltanloo, Mojtaba Ranjbar
Turkish Journal of Botany
Artemisinin, produced in very low amounts in Artemisia annua L. plants, is one of the most effective drugs in treating malaria. In this study, the effect of exogenous applications of methyl jasmonate (MeJA) and 2-isopentenyladenine (2-iP) in artemisinin production and the main genes of its biosynthesis pathway within a 1-week time period were investigated. Both MeJA and 2-iP increased artemisinin content, but no correlation was found between gene expression and its content. In plants treated with 2-iP, despite increased gene expression following elicitor application, downregulation of gene expression was also observed, which might be attributed to the negative effects of …

Gamma-Induced Infraspecific Polyploidy Via Cytomixis-Mediated Syncyte Formation In Papaver Somniferum (Papaveraceae), Girjesh Kumar, Sana Naseem
Turkish Journal of Botany
This is the first report on the phenomenon of syncyte manifestation through cytomictic transmigration in Papaver somniferum L. The occurrence characteristics and cytological depictions of cytomixis in the meiotic course of gamma-irradiated population reveal the mechanism leading to the origin of the cell fusions/syncytes. The event was more frequent in meiosis I and rare in meiosis II, indicating that the process atrophies at the end of the first meiotic division. The degree of occurrence of the phenomenon virtually concurred with the increase in the treatment dose of gamma irradiation. The phenomenon also affected the qualitative composition of postmeiotic products, i.e. …

Morphological And Genetic Variation Within And Among Four Quercus Petraea And Q. Robur Natural Populations, Cengi̇z Yücedağ, Oliver Gailing
Turkish Journal of Botany
Numeric-taxonomical and molecular techniques [nuclear simple sequence repeats (nSSRs), expressed sequence tag (EST) SSRs, and chloroplast SSRs] were used to estimate morphological and genetic differentiation within and among 4 Quercus petraea and Q. robur natural populations in Turkey. Canonical discriminant analysis (CDA) and principal component analysis (PCA) showed that 3 out of 15 studied leaf morphological characters (clustered hairs, number of intercalary veins, petiole length) mainly accounted for the discrimination between species. In accordance with earlier observations, the mean genetic differentiation between Q. petraea and Q. robur at 8 microsatellite loci (F_{ST} = 0.030) and at chloroplast microsatellites (G_{ST} = …

The results of SEM at higher magnification showed 6 types of seed surface patterns: tuberculate, reticulate, ruminate, reticulate-tuberculate, reticulate-areolate, and reticulate-fovate. In these seed surface patterns, there were diagnostic characteristics and differences at the specific level for Lepidium.
Sexual Phenotype Of Capparis Herbacea (Capparaceae), Nana Shakarishvili, Liana Osishvili
Sexual Phenotype Of Capparis Herbacea (Capparaceae), Nana Shakarishvili, Liana Osishvili
Turkish Journal of Botany
Floral morphology coupled with the morphometry of androecium revealed that Capparis herbacea Willd. has an andromonoecious sexual system, producing both male and perfect flowers on the same plant. Functionally male flowers develop more stamens with larger anthers than bisexual ones (63.6 ± 0.6 and 4.1 ± 0.01 mm; 58.1 ± 0.7 and 3.6 ± 0.02 mm, respectively). The ratio of male to perfect flowers ranges from 0.5 to 2.6 during the flowering season. The development of dense trichomes on the adaxial surface of the cavity made by variegated connate petals is presumably adaptive and serves to protect nectary exudate from …

Cadmium-Induced Structural Disturbances In Pisum Sativum Leaves Are Alleviated By Nitric Oxide, Tuan Anh Tran, Valya Vassileva, Petar Petrov, Losanka Petrova Popova
Turkish Journal of Botany
In the present study, the protective effect of nitric oxide (NO) against Cd-induced structural disturbances in pea (Pisum sativum) leaves was investigated. Cadmium treatment resulted in a decreased leaf size and thickness of the lamina, reduced intercellular spaces in the mesophyll, small pavement cells, and a high density of stomata. These abnormalities were partially or fully reversed by a simultaneous application of Cd and the NO donor, sodium nitroprusside (SNP). The concentration of 1000 µM SNP was very effective in counteracting the adverse effects of Cd and resulted in leaf structural parameters close to those of the control leaves. These …
