Glutamine synthetase (EC 6.3.1.2) is an enzyme which assimilates ammonium into amino acids. Therefore, GS plays an essential role in the metabolism of nitrogen. In vascular plants, GS is devided into two groups: cytosol - located isoform (GS1) and plastid – located isoform (GS2). Surveys have shown that GS1 gene was used widely to generate transgenic plants. Effects on the growth characteristics of GS1 transgenic plants have been reported in many researches.

The main goal of study "Effect of Bursaphelenchus spp. inoculation on carbohydrate concentrations of different pine species in forest stands of Düzce Forest Directorate" was to investigate the effects of nematode inoculation on the total carbohydrate concentrations of tree species. Native six Bursaphelenchus species were inoculated on three pine species (Pinus pinaster, P. nigra, and P. sylvestris) under natural stand conditions.

The raccoon dog (Nyctereutes procyonoides) was recorded for the first time in Turkey on May 10, 2019, and June 5, 2019, in the same location after 4668 nights of camera trapping in the forests of the Sarıkamış region and Allahuekber Mountains in eastern Turkey. It was recorded in a Scots pine (Pinus sylvestris) forest at 2340 m above sea level with extensive snow cover. Given that the nearest known population is in the forests of Georgia approximately 105 km away, there may already be a viable population in Turkey.

The cell cycle and cellular oxidative stress responses are tightly controlled for proper growth and development of Scots pine (Pinus sylvestris L.) seed. Programmed cell death (PCD) is an integral part of the embryogenesis during which megagametophyte cells in the embryo surrounding region (ESR) and cells in the nucellar layers face death.

The macrofungi collected from the Türkmenbaba mountain area in 2001-2003 were investigated. As a result of field and laboratory studies, 84 taxa belonging to 30 families were identified. Seven species belong to the class Ascomycetes and 77 species to Basidiomycetes. Seven of these taxa are new records for the Turkish macromycota.

The aim of this research was to determine the effects of bleaching chemicals on the bending strength of wood. For this purpose, sodium hydroxide + hydrogen peroxide, sodium hydroxide + calcium hydroxide + hydrogen peroxide, hypochlorite and hydrochloric acid were applied to pine (Pinus sylvestris L.), oriental beech (Fagus orientalis Lipsky), ash (Fraxinus excelsior L.) and oak (Quercus petraea spp.) for bleaching.

Various methods were progressively investigated to determine wood density within the most reliable void volume (porosity) values. Three softwood species of Bornmulleriana fir (Abies bornmulleriana Mattf.), Eastern spruce (Picea orientalis Lipsky), and Scots pine (Pinus sylvestris L.) grown indigenously in Turkey were selected to obtain a comparison among the green volume (GV), oven dry (OD) and maximum moisture content (MMC) methods.
