Nanoparticles, thanks to their superior properties such as large surface area and high reactivity, can be an alternative to traditional fertilizers for improving nutrient uptake. Furthermore, considering that chemical and physical synthesis methods require high energy consumption and cause environmental pollution, plant-mediated green synthesis of NPs has attracted great attention since it provides eco-friendly, biocompatible, and inexpensive solutions. In this present study, plant mediated green synthesis of Iron Oxide (FeO), Zinc Oxide (ZnO) and Titanium Dioxide (TiO) nanoparticles by using leaves (bay leaves) were carried out and their structural properties were characterized by UV visible spectra, Dynamic Light Scattering (DLS), Fourier Transform Infrared (FTIR), X-Ray Diffraction (XRD) and Transmission Electron Microscopy (TEM).

Background: Pistacia is a genus of dioecious plant species whose trees can take 4-5 years to reach the economically valuable fruit-bearing stage. The fruits have great importance as raw material in the food, healthcare, and baking industries. For that reason, the identification of individual plants in the early juvenile period for the pollination and positioning of trees is crucial for growers.

Sunflower is a globally important oilseed, food, and ornamental crop. This study seeks to investigate the genotoxic effects of tissue culture parameters in sunflower calli tissues belongs to two genotypes obtained via anther culture. Anthers were pretreated with cold for 24 hours at 4°C and heat for 2 days at 35°C in the dark and plated onto media supplemented with different concentrations and combinations of 6-benzylaminopurine, 2,4-dichlorophenoxyacetic acid, α-naphthalene acetic acid and indole-3-acetic acid.

The effectiveness of genes is known to be resistant to downy mildew (DM) disease affected by fungus in sunflower. In this study phenotypic analysis was performed using inoculation tests and genotypic analysis were carried out with three DM resistance genes and . A total of 69 simple sequence repeat markers and 241 F individuals derived from a cross of RHA-419 (R) x P6LC (S), RHA-419 (R) x CL (S), RHA-419 (R) x OL (S), RHA419 (R) x 9758R (S), HA-R5 (R) x P6LC (S) and HA89 (R) x P6LC (S) parental lines were used to identify resistant hybrids in sunflower.

In this study, the patterns of genetic variation and phylogenetic relationships of mastic tree (Pistacia lentiscus L.) genotypes including 12 males and 12 females were evaluated using SSR, RAPD, ISSR, and ITS markers yielding 40, 703, 929 alleles, and 260-292 base pairs for ITS1 region, respectively. The average number of alleles produced from SSR, RAPD, and ISSR primers were 5.

Expressed sequence tag (EST) markers have been used to assess variety and genetic diversity in wheat (Triticum aestivum). In this study, 1549 ESTs from wheat infested with yellow rust were used to examine the genetic diversity of six susceptible and resistant wheat cultivars. The aim of using these cultivars was to improve the competitiveness of public wheat breeding programs through the intensive use of modern, particularly marker-assisted, selection technologies.
